"Problem:

Jenny earns a base pay of $1000 per month plus a 5% commission on all sales. Last month she sold $8000 worth of products. What was her total earnings for the month?

Solution:

Jenny's commission for the month is 5% of $8000, which can be calculated as:

Commission = 5% of $8000 = (5/100) * $8000 = $400

Her total earnings for the month can be found by adding her base pay and commission:

Total Earnings = Base Pay + Commission

Total Earnings = $1000 + $400

Total Earnings = $1400

Therefore, Jenny's total earnings for the month were $1400." (ChatGPT, 2023)

The interest earned by Sarah in four (4) years is approximately $62.16.

The formula accrued amount in a compounded interest is expressed as;

A = P( 1 + r/n )^( n × t )

Where A is accrued amount, P is principal, r is interest rate and t is time.

Given that;

First, we convert R as a percent to r as a decimal

r = R/100

r = 7/100

r = 0.07

Now, the the values into the above formula and solve for accrued amount (A).

A = P( 1 + r/n )^( n × t )

A = $200( 1 + 0.07/1 )^( 1 × 4 )

A = $200( 1 + 0.07 )^( 4 )

A = $200( 1.07 )^( 4 )

A = $262.16

Now, we know that;

Accrued amount (A) = Principal (P) + Interest (I)

Solve for Interest (I)

$262.16 = $200 + I

I = $262.16 - $200

I = $62.16

Therefore, the interest earned is $62.16.

Step-by-step explanation:

that makes ORQ a right-angled triangle, and we can use Pythagoras

c² = a² + b²

c being the Hypotenuse (the side opposite of the 90° angle), a and b are the legs.

OQ is the radius of the circle = OM = LM/2 = 20/2 = 10 cm.

RQ = PQ/2 = 16/2 = 8 cm.

so, our Pythagoras equation looks like :

OQ² = RQ² + OR²

10² = 8² + OR²

100 = 64 + OR²

36 = OR²

OR = 6 cm

RM = OM - OR = 10 - 6 = 4 cm

The area of the region bounded by the curves y = x² + 6x + 9 and y = 4 is 16  ² / ₃ square units.

First, we need to find the points of intersection between the two curves. Set y = x² + 6x + 9 equal to y = 4:

x² + 6x + 9 = 4

Now, solve for x:

x² + 6x + 5 = 0

Factor the quadratic equation:

(x + 5)(x + 1) = 0

This gives us the solutions x = -5 and x = -1. These are the x-coordinates of the points of intersection.

Now, to find the area of the region bounded by the curves, we'll integrate the difference between the two functions with respect to x, from x = -5 to x = -1:

Area = ∫[4 - (x² + 6x + 9)]dx from -5 to -1

Area = ∫[5 - x² - 6x]dx from -5 to -1

Now, integrate:

Area = [5x - (x³/3) - 3x²] from -5 to -1

Plug in the limits:

Area = (5(-1) - (-1)³/3 - 3(-1)²) - (5(-5) - (-5)³/3 - 3(-5)²)

Area = (-5 - 1/3 - 3) - (-25 + 125/3 - 75)

Area = (-8 1/3) - (- 25/3)

Area = 16  ² / ₃ square units

The values of the variables and the side lengths are

From the question, we have the following parameters that can be used in our computation:

AB = AC

Perimeter = 27.3

Using the attached figure, we have

6x - 2y = x + 5

Evaluate

5x = 2y + 5

For the perimeter, we have

AC + AB + BC = 27.3

So, we have

6x - 2y + x + 5 + y + 6.3 = 27.3

Simplify

7x = y + 16

Multiply by 2

14x = 2y + 32

Subtract from 5x = 2y + 5

9x = 27

So, we have

x = 3

This means that

2y + 32 = 14 * 3

2y + 32 = 42

Evaluate

2y = 10

y = 5

For the side lengths, we have

AC + AB + BC = 27.3

So, we have

AC = 6(3) - 2(5) = 8

AB = 3 + 5 = 8

BC = 5 + 6.3 = 11.3

Answer:

Write the whole number as a fraction by placing it over 1. For example, if you want to multiply 2/5 by 3, you can write 3 as 3/1.

Multiply the numerators of the two fractions together. For example, 2/5 x 3/1 = (2 x 3) / 5 = 6/5.

Simplify the resulting fraction, if necessary, by reducing it to its lowest terms. For example, 6/5 can be simplified to 1 1/5 (or 1.2 as a decimal).

Therefore, when you multiply a fraction by a whole number, you multiply the numerator of the fraction by the whole number and keep the denominator the same.

Answer:

the value of (4m-n)/(n+2p) is 3/7.

Step-by-step explanation:

Let's substitute the given ratio in terms of a common multiplier, k:

m = 3k

n = 6k

p = 4k

Now we can substitute these values in the expression:

(4m-n)/(n+2p) = (4(3k) - 6k)/(6k + 2(4k)) = (12k - 6k)/(6k + 8k) = 6k/14k = 3/7

Therefore, the value of (4m-n)/(n+2p) is 3/7.

The jeweler made 4 bracelets and 6 necklaces using 172 grams of gold.

An equation is a mathematical statement that shows that two expressions are equal. It contains variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. Equations are used to solve problems by finding the values of the variables that make the equation true.

Let x be the number of bracelets made, and y be the number of necklaces made.

Then, we can create the following system of equations:

Equation 1: 7x + 24y = 172 (the total amount of gold used is 172 grams)

Equation 2: y = x + 2 (the number of necklaces made is 2 more than the number of bracelets made)

So, the variables are x (the number of bracelets made) and y (the number of necklaces made).

We can solve this system of equations to find the values of x and y. We can use substitution or elimination to solve for one variable and then plug it into the other equation.

Substitution method:

From Equation 2, we have y = x + 2. Substituting this into Equation 1, we get:

7x + 24(x+2) = 172

7x + 24x + 48 = 172

31x = 124

x = 4

So, the jeweler made 4 bracelets.

Plugging this into Equation 2, we get:

y = x + 2 = 4 + 2 = 6

So, the jeweler made 6 necklaces.

Therefore, the jeweler made 4 bracelets and 6 necklaces using 172 grams of gold.

5. The quadratic function for the height of the rock, h = -16·t² + 79·t + 50, indicates;

a. The height of the rock will be 125 feet above the beach at 1.28 seconds and 3.66 seconds after it is thrown

b. The maximum height reached is about 147.5 feet

The time it takes the rock to reach the maximum height is about 2.47 seconds

A quadratic function is a function of the form; f(x) = a·x² + b·x + c, where, a, b, and c are numbers, and a ≠ 0.

The initial velocity of the rock = 79 ft/s

Height of the cliff above the beach from which the rock is thrown = 50 feet

The function for the height of the rock above the beach is; h = -16·t² + 79·t + 50

Please find attached the graph of the height of the rock as a function of time, created with MS Excel.

Required; When the height of the rock will be 125 feet above the beach

When the height of the rock is 125 feet, we get;

h = 125 = -16·t² + 79·t + 50

-16·t² + 79·t + 50 - 125 = 0

-16·t² + 79·t - 75 = 0

The value of t obtained using an online tool are;

t = (79 + √(1441))/32 ≈ 3.66 and t = (79 - √(1441))/32 ≈ 1.28

The times at which the height of the rock will be 125 feet above the beach are; 1.28 seconds and 3.66 seconds after the rock is thrown

b. The maximum height of the rock can be obtained from the formula for finding the maximum height of a quadratic equation of the form; f(x) = a·x² + b·x + c, which is;

At the maximum point, x = -b/(2·a)

The function for the height; h = -16·t² + 79·t + 50, indicates that we get;

a = -16, b = 79, and c = 50

Therefore;

The time it takes the rock to reach the maximum height, t(max), is therefore;

t(max) = -79/(2 × (-16)) ≈ 2.47

It takes about 2.47 seconds for the rock to reach the maximum height

The maximum height, h(max) = -16 × 2.46875² + 79×2.46875 + 50 ≈ 147.5

The maximum height reached by the rock is about 147.5 feet

Answer:

Step-by-step explanation:

The possible rational zeros of a polynomial function are all the possible values of x, where x is a factor of the constant term of the function divided by a factor of the leading coefficient of the function.

For the polynomial function f(x) = x^4 - 5x^3 + 8x^2 - 20x + 16, the constant term is 16 and the leading coefficient is 1. Therefore, the possible rational zeros are all the possible values of x, where x is a factor of 16 divided by a factor of 1. That is, the possible rational zeros are:

±1, ±2, ±4, ±8, ±16

To check if any of these possible zeros are actually zeros of the function, we can use synthetic division or long division to test each one.

∠EAB and ∠ECD are alternate interior angles because AB and CD are parallel lines and line AC crosses through both parallel lines.

m∠EAB = m∠ECD because they are alternate interior angles.

ΔABE ≅ ΔCDE because there are two sets of congruent angles.

Answer:

CF =  12
DE  = 23
CD =  23
DF = 23.9

Step-by-step explanation:

We can see that there are 2 right-angled triangles: DEF and CDF with common side FD.

They are right angled triangles because the EF and CF are radii of the circle and these segments intersect the tangents at 90°

The common side DF is the hypotenuse for both triangles

The sides EF and CF are radii of the circle so EF = CF

We have two triangles which have two sides equal and one of the angles equal to the corresponding angle of the other

By the SSA theorem, the two triangles are similar

SSA Theorem

if two sides and an angle not included between them are respectively equal to two sides and an angle of the other then the two triangles are equal

Therefore by the law of similar triangles,

CD  = EF

Plugging in the expressions we get
13x - 16 = 4x + 11

Subtract 4x from both sides:
13x - 4x - 16 = 11
9x - 16 = 11

Add 16 to both sides:
9x - 16 + 16 = 11 + 16

9x = 27

x = 27/9 = 3

Therefore
ED = 4x + 11 = 4(3) + 11 = 12 + 11 = 23

and this is equal to CD

Using the Pythagorean theorem for right triangles,

For ΔDEF,

DF² = EF² + DE²

DF² = 12² + 23²

= 144 + 529

= 673

DF = √673

= 25.9422

= 25.9 rounded to the nearest tenth

So the measures of the segments are
CF = 12
DE = 23
CD = 23
DF = 23.9
