SYSTEM OF EQUATIONS: WHAT IS IT?

A group of two or more equations with the same variables is referred to as a system of equations. The collection of numbers that simultaneously make all the equations true is the system's solution.

For instance, take into account the equations below:

2x + y = 5

x - y = 1

There are two equations with two variables in this system (x and y). The collection of numbers that simultaneously satisfy both equations is the system's solution. The answer in this situation is x = 2 and y = 1.

We may solve for y by substituting the value of x in the system of equations, which is -4, into one of the equations.

Consider the following two equations:

axe + by = c

dx + ey = f

We can solve for y by substituting the value of x into one of the equations if we know it.

As an illustration, if x = -4, then we have:

2x + 3y = 5

4x - 3y = -16

We can change one of the equations to read x = -4:

2(-4) + 3y = 5

When we simplify this equation, we obtain:

-8 + 3y = 5

8 is added to both sides to get at:

3y = 13

When we multiply both sides by 3, we get:

y = 13/3

The values οf a and b that make the functiοn f cοntinuοus at x = -2 and x = 3 are a = -2 and b = 1

Describe Functiοn?

A functiοn is said tο be cοntinuοus if it has nο jumps, breaks, οr hοles in its graph. In οther wοrds, a functiοn is cοntinuοus if it can be drawn withοut lifting the pen frοm the paper. Fοrmally, a functiοn is cοntinuοus at a pοint x = c if the limit οf the functiοn as x apprοaches c frοm bοth the left and the right exists and is equal tο the value οf the functiοn at c.

Fοr example, the functiοn f(x) = x² is cοntinuοus everywhere because it is a smοοth curve with nο jumps οr breaks in its graph. On the οther hand, the functiοn g(x) = 1/x is cοntinuοus everywhere except at x = 0, where it has a vertical asymptοte and a hοle in its graph.

The cοncept οf cοntinuity is impοrtant in many areas οf mathematics, including calculus and analysis, as it allοws us tο study the behaviοr οf functiοns at specific pοints and οver intervals. It is alsο impοrtant in real-wοrld applicatiοns, such as in engineering and physics, where cοntinuοus functiοns mοdel physical phenοmena like mοtiοn, heat transfer, and fluid flοw.

Tο find the values οf a and b, we can use the cοntinuity οf the functiοn at x = -2 and x = 3. Fοr a functiοn tο be cοntinuοus at a pοint, it must exist at that pοint and its limit as x apprοaches that pοint frοm bοth sides must be equal.

At x = -2:

The left-hand limit οf f(x) as x apprοaches -2 is f(-2-) = 2(-2)² - 3 = 5.

The right-hand limit οf f(x) as x apprοaches -2 is f(-2+) = a(-2) + b.

Since the functiοn is cοntinuοus at x = -2, these limits must be equal:

f(-2-) = f(-2+) => 5 = -2a + b

At x = 3:

The left-hand limit οf f(x) as x apprοaches 3 is f(3-) = a(3) + b.

The right-hand limit οf f(x) as x apprοaches 3 is f(3+) = (6/3) - 3 = -1.

Since the functiοn is cοntinuοus at x = 3, these limits must be equal:

f(3-) = f(3+) => a(3) + b = -1

We nοw have twο equatiοns with twο unknοwns:

5 = -2a + b

a(3) + b = -1

Sοlving fοr b in terms οf a in the first equatiοn gives:

b = 2a + 5

Substituting this expressiοn fοr b intο the secοnd equatiοn gives:

a(3) + 2a + 5 = -1

3a + 5 = -1

3a = -6

a = -2

Substituting this value οf a intο the first equatiοn gives:

5 = -2(-2) + b

5 = 4 + b

b = 1

Therefοre, the values οf a and b that make the functiοn f cοntinuοus at x = -2 and x = 3 are a = -2 and b = 1.

A large statue is in the shape of a square pyramid. Each side of
the base of the square pyramid is 723 feet long, and the height
is 341 feet.
What is the volume of the statue?

Answers

The formula for the volume of a square pyramid is:

V = (1/3) × base area × height

Since each side of the base of the square pyramid is 723 feet long, the area of the base is:

base area = (723 feet)^2 = 522,129 square feet

Substituting this value and the height of the pyramid (341 feet) into the formula, we get:

V = (1/3) × 522,129 square feet × 341 feet

Multiplying and simplifying, we get:

V = 62,695,147 cubic feet

Therefore, the volume of the statue is approximately 62,695,147 cubic feet.

If h(x) = √6 + 5f(x), where f(2)= 6 and f'(2) = 5, find h'(2).

Answers

Using chain rule to find the derivative of h(x), the value of h'(2) is 25

What is the value of the function

The chain rule is a rule in calculus that allows us to find the derivative of a composite function. A composite function is a function that is composed of two or more functions. For example, if we have two functions f(x) and g(x), then the composite function, denoted by h(x), would be h(x) = f(g(x)).

Using the chain rule, we can find the derivative of h(x) with respect to x as follows:

h(x) = √6 + 5f(x)

h'(x) = d/dx (√6 + 5f(x))

h'(x) = d/dx (√6) + d/dx (5f(x))

h'(x) = 0 + 5f'(x)

Now, to find h'(2), we substitute x=2 in the expression above and use the given value of f'(2):

h'(2) = 5f'(2)

h'(2) = 5(5)

h'(2) = 25

Therefore, h'(2) = 25.

15,183
21,746
21,407.
26,154

Answers

Answer:

Step-by-step explanation:

To determine the cost of goods manufactured, we need to add up the total manufacturing costs incurred during the month and subtract the cost of work in process inventory on March 1, then add the cost of work in process inventory on March 31:

Total Manufacturing Costs = Cost of Direct Materials Used + Direct Labor + Factory Overhead

Total Manufacturing Costs = $18,435 + $26,510 + $37,267

Total Manufacturing Costs = $82,212

Cost of Goods Manufactured = Total Manufacturing Costs - Work in Process Inventory, March 1 + Work in Process Inventory, March 31

Cost of Goods Manufactured = $82,212 - $15,183 + $21,746

Cost of Goods Manufactured = $88,775

Therefore, the cost of goods manufactured for the month of March is $88,775.

To determine the cost of goods sold, we need to calculate the cost of goods available for sale, which is the sum of the cost of goods manufactured and the cost of finished goods inventory on March 1, and then subtract the cost of finished goods inventory on March 31:

Cost of Goods Available for Sale = Cost of Goods Manufactured + Finished Goods Inventory, March 1

Cost of Goods Available for Sale = $88,775 + $21,407

Cost of Goods Available for Sale = $110,182

Cost of Goods Sold = Cost of Goods Available for Sale - Finished Goods Inventory, March 31

Cost of Goods Sold = $110,182 - $26,154

Cost of Goods Sold = $84,028

Therefore, the cost of goods sold for the month of March is $84,028.

In a popular shopping centre, the waiting time for an ABC Bank ATM machine is found to be uniformly distributed between 1 and 5 minutes. What is the probability of waiting between 2 and 4 minutes to use the ATM?​

Answers

The probability of waiting between 2 and 4 minutes to use the ATM is 0. 5 or 50 %.

How to find the probability ?

For a uniform distribution, the probability density function is constant within the given interval. In this case, the interval is between 1 and 5 minutes. The length of the interval is 5 - 1 = 4 minutes.

Now, we want to find the probability of waiting between 2 and 4 minutes. The length of this subinterval is 4 - 2 = 2 minutes. To find the probability of waiting between 2 and 4 minutes, we multiply the probability density by the length of the subinterval:

Probability = probability density × (length of subinterval) = (1/4) × 2 = 1/2 = 0.5

So, the probability of waiting between 2 and 4 minutes to use the ATM is 0.5 or 50%.

Given the functions f(x)= 1/x-3 -1 and g(x)= 1/x+4-3. Which statement describes the transformation of the graph of the function f onto the graph of the function g.

Answers

For the functions  f(x)= 1/x-3 -1 and g(x)= 1/x+4-3, the transformation of the graph shows that The graph shifts 7 units left and 2 units down.

What is the definition of a function?

In mathematics, a function is a rule or relationship between two sets of values, known as the domain and the range, that assigns to each element in the domain a unique element in the range.

More formally, a function f is a set of ordered pairs (x, y), where x is an element of the domain and y is an element of the range, such that each element in the domain is paired with exactly one element in the range. This can be written symbolically as:

f: X → Y

where X is the domain and Y is the range, and the arrow → indicates that each element in X is mapped to a unique element in Y.

Now,

To understand the transformation of the graph of the function f onto the graph of the function g, we need to analyze the effect of the changes in the functions.

First, let's consider the function f(x) = 1/(x-3) - 1. This function is a rational function with a vertical asymptote at x = 3 and a horizontal asymptote at y = -1. It is also reflected about the x-axis compared to the basic reciprocal function 1/x.

Next, let's consider the function g(x) = 1/(x+4) - 3. This function is also a rational function with a vertical asymptote at x = -4 and a horizontal asymptote at y = -3. It is also reflected about the x-axis compared to the basic reciprocal function 1/x.

To determine the transformation from f(x) to g(x), we need to compare the changes in the two functions. We can see that:

The term (x-3) in f(x) has been replaced with (x+4) in g(x), which indicates a horizontal shift of 7 units to the left.

The term -1 in f(x) has been replaced with -3 in g(x), which indicates a vertical shift of 2 units down.

Therefore,

              the graph of the function f has been shifted 7 units to the left and 2 units down to obtain the graph of the function g. So, the correct statement is:

                    The graph shifts 7 units left and 2 units down.

Find the component if the Vector BC if B=(2,-7) and C= (-4,-5)

Answers

The component of vector BC in the direction of the x-axis is (-6, 0).

What is the component of the vector on x-axis?

To find the component of vector BC, we need to find the projection of vector BC onto a given vector.

The component of vector BC in the direction of the x-axis can be found using the formula:

comp(x) = (BC · unit(x)) · unit(x)

where;

BC is the vector from B to C, unit(x) is the unit vector in the direction of the x-axis, and comp(x) is the component of vector BC in the direction of the x-axis.

To find unit(x), we can use the following formula:

unit(x) = (1, 0)

since the x-axis is the horizontal axis and its unit vector has a horizontal component of 1 and a vertical component of 0.

Now, let's calculate the component of vector BC in the direction of the x-axis:

BC = C - B = (-4, -5) - (2, -7) = (-6, 2)

|BC| = √((-6)² + 2²)

|BC| = √(40)

unit(x) = (1, 0)

(BC · unit(x)) = (-6) · 1 + (2) · 0 = -6

A 16 foot ladder is propped up against the roof of a house. The angle of elevation is 62 degrees. How tall is the house?

Answers

Answer is below.

Let's call the height of the house "h".

The ladder is propped up against the house, forming a right triangle with the wall of the house and the ground. The ladder is the hypotenuse of the triangle, and the height of the house is one of the legs.

We know that the length of the ladder is 16 feet, and the angle of elevation is 62 degrees. We can use trigonometry to find the height of the house.

The trigonometric function that relates the angle of elevation to the height and length of the ladder is the tangent function:

tan(62) = h/16

To solve for h, we can multiply both sides by 16:

16 tan(62) = h

Using a calculator, we can evaluate the tangent of 62 degrees to get:

16 tan(62) ≈ 28.6

So the height of the house is approximately 28.6 feet.

Answers

Therefore, the value of x is 348 the measure of angle ABD is (0.12x + 67) deg and the measure of angle CBD is (0.13x + 26).

What is angle?

An angle is a geometric figure formed by two rays, called the sides of the angle, that share a common endpoint, called the vertex of the angle. Angles are measured in degrees (°) or radians (rad) and are typically denoted by the vertex letter. The size of an angle is determined by the amount of rotation needed to rotate one of the sides of the angle onto the other side. An angle of 90 degrees is called a right angle, an angle less than 90 degrees is called an acute angle, and an angle greater than 90 degrees but less than 180 degrees is called an obtuse angle. Angles are used in a variety of fields, including geometry, trigonometry, and physics, and play an important role in understanding the properties and relationships of shapes and objects.

Here,

Since angles ABD and CBD are adjacent and share side BD, their measures must add up to 180 degrees (since they form a straight line). Therefore, we can write the following equation:

ABD + CBD = 180

Substituting the given measures of angles ABD and CBD, we get:

(0.12x + 67) + (0.13x + 26) = 180

Simplifying the left side of the equation by combining like terms, we get:

0.12x + 0.13x + 67 + 26 = 180

0.25x + 93 = 180

Subtracting 93 from both sides of the equation, we get:

0.25x = 87

Dividing both sides of the equation by 0.25, we get:

x = 348

the regular price of any souvenir at a gift shop is x dollars. During a sale today, if a customer purchases one souvenir at its regular price, the price of each additional souvenir will be 0.3x less than the regular price. if carmen purchases 10 souvenirs today, and x=$30, what does carmen pay

Answers

Answer:

If x = $30 is the regular price of a souvenir, then the sale price for each additional souvenir will be 0.3x = 0.3($30) = $9 less than the regular price. Therefore, the sale price of each additional souvenir will be:

Sale price = Regular price - $9

Sale price = $30 - $9

Sale price = $21

Since Carmen purchases 10 souvenirs, she pays the regular price for the first souvenir and the sale price for the remaining 9 souvenirs. Therefore, the total cost for all 10 souvenirs will be:

Total cost = (Regular price for first souvenir) + (Sale price for 9 additional souvenirs)

Total cost = ($30) + ($21 x 9)

Total cost = $30 + $189

Total cost = $219

Therefore, Carmen pays $219 for 10 souvenirs during the sale.

What is the total amount in Naira that Musa will pay the bank if the commission charged by the bank is 34Naira on each bank draft and he buys a bank draft of (a) $427 (b) £335 (take the exchange rate to be $1=2Naira, £1=15Naira)

Answers

Answer:

(a) Musa wants to buy a bank draft for $427. Since $1 = 2 Naira, the cost of the bank draft in Naira will be:

$427 x 2 Naira/$1 = 854 Naira

The commission charged by the bank is 34 Naira on each bank draft, so the total amount in Naira that Musa will pay the bank will be:

854 Naira + 34 Naira = 888 Naira

Therefore, Musa will pay the bank a total of 888 Naira for the bank draft.

(b) Musa wants to buy a bank draft for £335. Since £1 = 15 Naira, the cost of the bank draft in Naira will be:

£335 x 15 Naira/£1 = 5,025 Naira

The commission charged by the bank is 34 Naira on each bank draft, so the total amount in Naira that Musa will pay the bank will be:

5,025 Naira + 34 Naira = 5,059 Naira

Therefore, Musa will pay the bank a total of 5,059 Naira for the bank draft.

a) Musa will pay the bank a total of ₦49,106 (42,700 + 6,406) if he buys a bank draft of $427. The conversion rate is $1 = ₦2 and the charges amount to 34 × 427 = 14,358, so the total amount to be paid is 42,700 + 14,358 = 56,058. Subtracting the commission, the total amount is 56,058 - 6,406 = 49,102.

b) Musa will pay the bank a total of ₦68,030 (50,500 + 17,530) if he buys a bank draft of £335. The conversion rate is £1 = ₦15 and the charges amount to 34 × 335 = 11,290, so the total amount to be paid is 50,500 + 11,290 = 61,790. Subtracting the commission, the total amount is 61,790 - 17,530 = 68,030.

In an arithmetic sequence, the sum of the first 8 terms is 88. The product of the 1st and the 8th terms is 120. Calculate values for the 1st term.​

Answers

Answer: Let's call the first term of the arithmetic sequence "a", and the common difference between the terms "d".

Then, we know that the sum of the first 8 terms is 88, so we can write:

a + (a + d) + (a + 2d) + ... + (a + 7d) = 88

Using the formula for the sum of an arithmetic sequence, we can simplify this to:

8a + 28d = 88

We also know that the product of the 1st and 8th terms is 120, so we can write:

a(a + 7d) = 120

Now we have two equations with two variables. We can solve for one of the variables in terms of the other and substitute into the other equation to solve for the remaining variable.

Solving the first equation for d:

d = (88 - 8a)/28

Substituting into the second equation:

a(a + 7[(88-8a)/28]) = 120

Multiplying both sides by 28 to eliminate the fraction:

28a^2 + 154a - 960 = 0

We can factor this quadratic equation as:

(2a - 15)(14a + 64) = 0

So either 2a - 15 = 0 or 14a + 64 = 0. Solving for "a" in each case, we get:

a = 15/2 or a = -64/14

Since we're looking for the first term of the sequence, which must be positive, we can discard the negative value and conclude that the first term is:

a = 15/2

Therefore, the first term of the arithmetic sequence is 7.5.

the equation. Then write a related multiplication equation to solve.

Answers

The equation is true, we have confirmed that x = 3 is the correct solution.

The equation shown in the image is:

4x + 12 = 24

To write a related multiplication equation, we can simplify the left side of the equation by factoring out the common factor of 4:

4(x + 3) = 24

By multiplying both sides of the equation by 4, we can now find x:

x + 3 = 6

x = 6 - 3

x = 3

Therefore, the solution to the original equation is x = 3. We can check this solution by substituting it back into the original equation:

4x + 12 = 24

4(3) + 12 = 24

12 + 12 = 24

24 = 24

Since the equation is true, we have confirmed that x = 3 is the correct solution.
