Answer 1

Answer:

B

Step-by-step explanation:

Soemthing is a function if it can pass the vertical line test

the vertical line test is when you draw a vertical line and it only touches the graph once

Another way of thinking about this is no function can have two of the same values on the x axis

I'm not too sure what's happening with the third response but the answer is B

now let's plug in the values to see

51-5= 66 63-6 = 57

The expression for the given rectangle with width x and area y is[tex]y = -x^{2} +32[/tex]

it is given that

area of the rectangle = y

width of the rectangle = x

so the length of the rectangle will be = area/width = [tex]\frac{y}{x}[/tex]

perimeter = 64

What is the perimeter of a rectangle?

Perimeter is the sum of all four sides of the rectangle.

we can say that,

2(length + breadth) = 64

[tex]2( \frac{y}{x} + x)=64\\\\[/tex]

[tex]\frac{y}{x} + x= 32[/tex]

[tex]\frac{y + x^{2} }{x} = 32[/tex]

[tex]y+x^{2} = 32x[/tex]

[tex]y = -x^{2} +32[/tex]

therefore, the expression for the area of the rectangle,

[tex]y = -x^{2} +32[/tex]

Which of the following equations could represent a town with an initial population of 875 people and an annual growth rate of approximately 2%?

A. y = 875 ⋅ x1.02
B. y = 875 (1.02)x
C. y = 875(2)x
D. y = 875 • 1.02x

Answers

Answer:

B

Step-by-step explanation:

1+0.02=1.02

875(1.02)^x

The equation is y = 875 (1.02)ˣ represents a town with an initial population of 875 people and an annual growth rate of approximately 2%. which is the correct answer would be an option (B).

What is an exponential function?

An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.

Initial population = 875 people

Growth rate = 2%

The growth rate is the base of the exponent instead of the initial population.

As per the given situation, the required equation would be as:

y = 875 (1 + 2%)ˣ

y = 875 (1 + 0.02)ˣ

y = 875 (1.02)ˣ

In this equation, x represents the number of years after the initial population of 875 people.

Hence, the correct answer would be option (B).

The number of visitors to a certain Web site triples every month. The number of visitors is modeled by the expression 900 * 3^m​, where m is the number of months after the number of visitors was measured. Evaluate the expression for m=-2. What does the value of the expression represent in the​ situation?

Answers

Answer:

[tex]900\times 3^m[/tex] = 100

Step-by-step explanation:

The number of visitors is modeled by the expression [tex]900\times 3^m[/tex]

Where m is the number of months after the number of visitors was measured.

We need to evaluate the above expression for m = -2.

So,

[tex]900\times 3^m=900\times 3^{-2}\\\\=900\times \dfrac{1}{3^2}\\\\=900\times \dfrac{1}{9}\\\\=100[/tex]

At m = -2, the value of the above expression is equal to 100.

Simplify both sides of the equation.

7y - 4 = 5y + 13

Subtract 5y from both sides.

2y - 4 = 13

Add 4 to both sides.

2y = 17

Trapezoid ABCD has vertices A(-5,9) B(-2,9) C(-8,0) D(1,0) after a translation of 2 units right and 3 units down followed by a dilation with a scale factor of 2/3. What are the vertices of trapezoid RSTU

Answers

Answer:

(-2,4), (0,4), (-4,-2) and (2,-2)

Step-by-step explanation:

Given

[tex]A = (-5,9)[/tex]

[tex]B = (-2,9)[/tex]

[tex]C = (-8,0)[/tex]

[tex]D = (1,0)[/tex]

[tex]Translation: 2\ units\ right\ \& \ 3\ units\ down[/tex]

[tex]Dilation: \frac{2}{3}[/tex]

Required

Determine the vertices of the image RSTU

When a coordinate (x,y) is translates b units right, the new coordinate is: (x + b, y)

So, translation 2 units right gives:

[tex]A = (-5,9)[/tex] ---> [tex]A' = (-5 + 2,9) = (-3,9)[/tex]

[tex]B = (-2,9)[/tex] ---> [tex]B' = (-2 + 2,9) = (0,9)[/tex]

[tex]C = (-8,0)[/tex] ---> [tex]C' = (-8 + 2,0) = (-6,0)[/tex]

[tex]D = (1,0)[/tex] --- > [tex]D' = (1 + 2,0) = (3,0)[/tex]

When a coordinate (x,y) is translates b units down, the new coordinate is: (x, y-b)

So, translation 3 units down gives:

[tex]A' = (-3,9)[/tex] ---> [tex]A" =(-3,9-3) =(-3,6)[/tex]

[tex]B' = (0,9)[/tex] --> [tex]B" =(0,9-3) =(0,6)[/tex]

[tex]C' = (-6,0)[/tex] --> [tex]C" =(-6,0-3) = (-6,-3)[/tex]

[tex]D' = (3,0)[/tex]--> [tex]D"=(3,0-3) = (3,-3)[/tex]

Lastly, dilation of 2/3 gives:

[tex]New = Old * \frac{2}{3}[/tex]

[tex]R = (-3,6) * \frac{2}{3} = (-2,4)[/tex]

[tex]S = (0,6) * \frac{2}{3} = (0,4)[/tex]

[tex]T = (-6,-3) * \frac{2}{3} = (-4,-2)[/tex]

[tex]U = (3,-3) * \frac{2}{3} = (2,-2)[/tex]

Hence, the coordinates of RSTU are: (-2,4), (0,4), (-4,-2) and (2,-2)

Jackie's commute is 15 minutes longer than Laura's. If Laura drives 12 minutes for every 17 minutes Jackie drives what are both Jackie's and Laura's drives?

Answers

Answer:

Laura drives for [tex]36\ \text{minutes}[/tex] while Jackie drives for [tex]51\ \text{minutes}[/tex]

Step-by-step explanation:

Laura's commute is [tex]x\ \text{minutes}[/tex]

Jackie's commute is

[tex]x+15[/tex]

Laura drives 12 minutes for every 17 minutes Jackie drives so

For every minutes Laura drives Jackie drives [tex]\dfrac{17}{12}\ \text{minutes}[/tex]

So,

[tex]\dfrac{17}{12}=\dfrac{x+15}{x}\\\Rightarrow 17x=12x+180\\\Rightarrow 5x=180\\\Rightarrow x=\dfrac{180}{5}\\\Rightarrow x=36\ \text{minutes}[/tex]

Hence, Laura drives for [tex]36\ \text{minutes}[/tex] while Jackie drives for [tex]36+15=51\ \text{minutes}[/tex].
