The line x+y=3 and the circle x^2+y^2=17
Solve the simultaneous equations

Answers

Answer 1

The two solutions of the system of equations are (4, -1) and (-1, 4).

How to solve the system of equations?

Here we want to solve the system of equations below:

x + y = 3

x^2 + y^2 = 17

We can isolate x on the first equation to get:

x = 3 - y

And replace that in the other equation to get:

(3 - y)^2 + y^2 = 17

9 - 6y  + y^2 + y^2 = 17

2y^2 - 6y + 9 - 17 = 0

2y^2 - 6y - 8 = 0

y^2 - 3y -4 = 0

Using the quadratic formula we will get the solutions:

[tex]y = \frac{3 \pm \sqrt{(-3)^2 - 4*1*(-4)} }{2} \\\\y = \frac{3 \pm5 }{2}[/tex]

So the two solutions are:

y = (3 + 5)/2 = 4

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

The correspondent values of x are given by evaluating the line.

x + 4 = 3

x = 3 - 4 = -1

So we have the point (-1, 4)

x - 1 = 3

x = 3 + 1

x = 4

So we have the point (4, -1)

The minimum value of Y is -6 and the maximum value is 10. The range is {-6, 1, 2, 3, 10}.

What is the domain and how is the range calculated range ?

Domain of Y = -x³ + 2: A = {-2, -1, 0, 1, 2}. The equation is defined for all x in the set A.

Range of Y = -x³ + 2: To find the range, we need to find the minimum and maximum values of Y for x in the set A. Using the formula Y = -x³ + 2, we can substitute the values of x from the set A and find the corresponding values of Y:

x = -2, Y = -(-8) + 2 = 10

x = -1, Y = -(-1) + 2 = 3

x = 0, Y = -(0) + 2 = 2

x = 1, Y = -(1) + 2 = 1

x = 2, Y = -(8) + 2 = -6

Thus, the minimum value of Y is -6 and the maximum value is 10. The range is {-6, 1, 2, 3, 10}.

Relation Y = -x³ + 2 is a function: A relation is a function if every input x in the domain corresponds to only one output Y in the range. To check if the relation is a function, we need to ensure that no two different inputs in the domain result in the same output.

For this relation, every input x in the domain results in only one unique output Y, so the relation is a function.

Function Notation: If the relation is a function, we can write it in function notation as: f(x) = -x³ + 2, where f is the function name and x is the input.

Evaluating f(-5), f(0) and f(1):

f(-5) = -(-125) + 2 = 127

f(0) = -(0) + 2 = 2

f(1) = -(1) + 2 = 1

Thus, f(-5) = 127, f(0) = 2 and f(1) = 1.

Carol is cross-country skiing. The table shows the distance she traveled after various numbers of minutes. What is the rate of change?

Answers

The rate of change for the Carol with respect to time is 3/16 miles per minute.

What is the rate of change?

The rate of change (ROC) measures how quickly a variable alters over a predetermined amount of time. When discussing momentum, the term "rate of change" (ROC) is frequently used. It is typically defined as the ratio of a change in one variable to a matching change in another; visually, the rate of change is represented by the slope of a line.

Given The table shows the distance Carol traveled after various numbers of minutes,

Input        Output

 2            1/6

 3          17/48

 4          13/24

 5          35/48

 6          11/12

Here, the output values from 1/6 to 11/12 indicate the distance in miles whereas the input values from 2 to 6 describe the time in minutes.

by utilizing the first two sets of input-output numbers, calculating the rate of change

Relative change = change in distance/change in time

(17/48 - 1/6)/(3-2) = (17/48 - 8/48) /1 = 9/48 = 3/16 miles per minute

Find the area of the polygon with the given vertices. $K(-3,3),L(3,3),M(3,-1),N(-3,-1)$

Answers

The area of the polygon is 24 unit².

What is Polygons?

Polygons are closed figures which has at least three set of line segments joined together.

The polygon with least number of sides is triangle.

We have four coordinates of vertices given, K(-3,3), L(3,3), M(3,-1), N(-3,-1).

So the polygon must be a quadrilateral.

Length of KL = [tex]\sqrt{(3--3)^{2} + (3-3)^2 }[/tex] = [tex]\sqrt{6^2}[/tex] = 6

Length of LM = [tex]\sqrt{(3-3)^2+(-1-3)^2}[/tex] = [tex]\sqrt{(-4)^2}[/tex] = 4

Length of MN =[tex]\sqrt{(-3-3)^2+(-1--1)^2}[/tex] = [tex]\sqrt{(-6)^2}[/tex] = 6

Length of NK = [tex]\sqrt{(-3--3)^2+(3--1)^2}[/tex] = [tex]\sqrt{4^2}[/tex] = 4

So we get that, opposite sides are having equal length.

So the polygon must be a rectangle.

Area of the rectangle = Length × Width

                                    = 6 × 4

                                    = 24 units²

Given that the interest is paid into his account monthly (and calculated monthly), work out how much money Luke

will have in his account after 6 years and 3 months.

Answers

As per the formula of compound interest the amount in his account after 6 year 3 months is $40,085.307

In math the term called compound interest is defined as when you earn interest on both the money you've saved and the interest you earn.

Here we know that Luke invests 34000 into an account that pays 3. 4% compound interest per annum for the first two years and 2. 3% thereafter.

Here we need to find the amount in his account after 6 years and 3 months.

Then it can be calculated as,

FV = PV(1 + i)ⁿ

Here we know that PV = 34000 and i = 3.4% for two years,

Then the FV is value is calculated as,

=> FV = 34000(1 + 3.4/100)²

=> FV = 34000 ( 1 + 0.034)²

=> FV = 36351.304

Similarly, the FV value of 4 years 3 months is calculated as,

=>  FV = 36351.304(1 + 2.3/100)⁴°³

=> FV = 36351.304(1 + 0.023)⁴°³

Answers

Height is an example of a variable that uses the ratio scale.

Hence, option (a) is the correct choice.

Weight, height, and distance are all ratio variables. The ratio scale allows you to add, subtract, divide, and multiply data. Ratio scales are further distinguished from interval scales by the presence of a 'true zero'.

Height is an excellent example of a measuring scale based on a ratio. It is not nominal or ordinal since each change in the height unit (inches, metres, feet, etc.) has a standard distance between them, and it is not interval because height has a genuine zero.

Height, for example, is ratio data. There is no such thing as negative height. If the height of an item is 0, there is no object. This is not the same as talking about temperature.

To represents JKLM is a parallelogram the required value of x is equal to 7.

In the parallelogram JKLM,

Let us consider the measure of each side in form of 'x' is represented by :

JK = 4x + 13

KL = 4x - 1

LM = 3x + 20

MJ = 5x - 8

Opposite side of the parallelogram JKLM are congruent to each other.

JK = LM

⇒ 4x + 13 = 3x + 20

⇒ 4x - 3x = 20 - 13

⇒ x = 7

When

KL = MJ

⇒ 4x - 1 = 5x - 8

⇒ 5x - 4x = 8 - 1

⇒ x = 7

JK = 4(7) + 13

    = 41

LM = 3(7) + 20

     = 41

KL = 4(7) -1

Answers

To find out how many cans of white paint Emma will need to mix with 12 cans of pink paint, we can use the proportion of white paint to pink paint that she is currently using: 6 cans of white paint to every 4 cans of pink paint.

We can set up an equation using the proportion:

white paint/pink paint = 6/4 =3/2

We know that Emma wants to use 12 cans of pink paint, so we can use this information to solve for the number of cans of white paint she needs:

white paint/pink paint = 3/2

white paint = (3/2) * pink paint

white paint = (3/2) * 12 cans

white paint = 18 cans

So Emma will need 18 cans of white paint to mix with 12 cans of pink paint to get the desired color.

The amount of paint needed is 176/36000 = 0.0049 gallons, which is equivalent to 4.9 milliliters, rounded to the nearest hundredth.

To calculate how much paint Mr.Todd needs to buy to cover the outside of the entire birdhouse, we must first know the dimensions of the birdhouse. Let's assume the birdhouse has the dimensions of 10 inches long, 8 inches wide and 6 inches tall, and each side requires 1 coat of paint. The total surface area of the birdhouse is then 10 x 8 + 10 x 6 + 8 x 6 = 176 inches squared. Next, we need to know the coverage of the paint, which we will assume is 250 square feet per gallon. Since 1 square foot is equal to 144 square inches, the coverage of the paint is 36000 square inches per gallon. To find out how many gallons of paint are needed to cover the birdhouse, we need to divide the total surface area of the birdhouse (176 square inches) by the coverage of the paint (36000 square inches per gallon). Therefore, the amount of paint needed is 176/36000 = 0.0049 gallons, which is equivalent to 4.9 milliliters, rounded to the nearest hundredth.

Let x be the number of cupcakes sold for John's total pay to be the same for both companies

For the first company

Salary = $800/week

Commission is $0.30 per cupcake

For sales of x cupcakes, total commission = 0.30x

Total pay = Weekly salary + Total commission from sales

Total Pay = 800+ 0.3x

For the second company
Salary = 350 /week

Commission: $1.30 per cupcake

For sales of x cupcakes, total commission = 1.30x

Total Pay = Weekly salary + Total commission from sales

Total Pay = 350 + 1.3x

If both pay must be he same,
800 + 0.3x = 350 + 1.3x

800-350 = 1.3x - 0.3x

450 = 1x

x = 450 cupcakes ANSWER

Answer: 450

Step-by-step explanation:

    If we let x and y represent the number of cupcakes John sells and his total weekly income, respectively, we get the following system of equations.

=0.35x+845

=1.4x+372.5

Since both equations are solved for y​, any substitution for y​ will result in the following

211.4 x+372.5&=0.35

x+845

1.4x+372.5

=0.35x+845

Solving for x will give us the number of cupcakes John needs to sell weekly for each paycheck to be the same. Doing so, we get

1.4 x+372.5&=0.35     x+845

1.05 x&=472.5x=450

1.4x+372.5

1.05x

x

=0.35x+845

=472.5

=450

Therefore, John needs to sell 450450​ cupcakes each week for both salaries to be the same.

Write an equation that represents the line use exact numbers

Answers

The equation of the line is 6x-5y = 25.

What is equation of line?

When the slope of the line being studied is known, and the provided point is also the y intercept, the slope intercept formula, y = mx + b, is utilised (0, b).   It provides both a slope and an intercept, which is why the form is known as the slope-intercept equation.

Here in the given graph the points are [tex](x_1,y_1)=(0,-5)[/tex] and [tex](x_2,y_2)=(5,1)[/tex]

Now using slope formula  m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

=> slope m = [tex]\frac{1-(-5)}{5-0}[/tex]

=> m =  [tex]\frac{1+5}{5} = \frac{6}{5}[/tex]

Now using equation formula [tex]y-y_1 = m(x-x_1)[/tex] then

=> [tex]y - (-5) = \frac{6}{5}(x-0)[/tex]

=> y+5 = [tex]\frac{6}{5}[/tex]x

=> 5y+25 = 6x

=> 6x-5y = 25.

Hence the equation of line is 6x-5y = 25.

at time , a tank contains oz of salt dissolved in gallons of water. then brine containing oz of salt per gallon of brine is allowed to enter the tank at a rate of gal/min and the mixed solution is drained from the tank at the same rate. (a) how much salt is in the tank at an arbitrary time? 200-140e^(-t/25) oz. (b) how much salt is in the tank at time min?

Answers

The amount of salt in the tank is decreasing exponentially with time.

At time t, the amount of salt in a tank containing oz of salt dissolved in gallons of water can be calculated using the following formula:

Salt in tank (oz) = 200 - 140e^(-t/25)

For example, at time t = 10 min, the amount of salt in the tank is 200 - 140e^(-10/25) = 200 - 140(0.7787) = 124.42 oz.

This calculation assumes that brine containing oz of salt per gallon of brine is allowed to enter the tank at a rate of gal/min and the mixed solution is drained from the tank at the same rate. Thus, the amount of salt in the tank is decreasing exponentially with time.

Circle one: KE / GPE / both

Show your work for finding the values of each type of energy the object has:

Answers

The object has both kinetic energy and potential energy.

The values of each type of energy the object has are KE = 67.5 J

GPE = 367.5 J

How to find the energy of the object?

Energy is the ability to do work. It can take many forms, such as kinetic energy (energy of motion), potential energy (stored energy) etc.

If a 15-kg child is tossed up into the air by her parent and the child is 2.5 meters off the ground traveling 3 m/s.

Then boy has kinetic energy due to his motion and also has potential energy due to his height.

Thus, M = 15-kg, h = 2.5 meters and V = 3 m/s

KE = 1/2(M)(V)² = 1/2 × 15 × 3² = 67.5 J

GPE = mgh = 15 × 9.8 × 2.5 = 367.5 J

KE + PE = 67.5 + 367.5 = 435 J
