Amanda went into the grocery business starting with five stores. After one year, she opened two more stores. After two years, sh

e opened two more stores than the previous year. If Amanda expands her grocery business following the same pattern, which of the following graphs represents the number of stores she will own over time?

Step-by-step explanation:

We have been given that Amanda went into the grocery business starting with five stores. This means that initial value or y-intercept is 5.

We are also told that after one year, she opened two more stores. After two years, she opened two more stores than the previous year. This means that rate of change or slope is 2.

So the line representing the number of stores Amanda will own over time would be y=2x+5.

Upon graphing our given equation we will get our required graph as shown in the attachment.

I need help with this
VashaNatasha [74]
The answer is b. It cannot be c cause the answer would be a negative number. It cannot be a because there would be more than 100 lollipops altogether. And it cannot be d because the answer would be a fraction. There was 29 lollipops altogether. Hope this helps!

Which function is shown in the graph below?
Paha777 [63]
It is the second function:
y=(1/2)^(x-3)
When x=0, the exponent is -3.  (1/2)^-3 is 8.
y = 8+1 = 9

Find the missing length of the triangles.
slega [8]

They are both right triangles so we can use the Pythagorean

theorem to solve.

6. B = sqrt(15^2-9^2)

B = 12 mm

7. B = sqrt(26^2-10^2)

B = 24 Cm

A rocket is launched from a tower what time will the rocket reach its max
Lena [83]

Answer:

Step-by-step explanation:

A science class designed a ball launcher and tested it by shooting a tennis ball up and off the top of a 15-story building. They determined that the motion of the ball could be described by the function: h(t) = -16t2 + 144t + 160, where ‘t’ represents the time the ball is in the air in seconds and h(t) represents the height, in feet, of the ball above the ground at time t.

a) Graph the function h(t) = -16t2 + 144t + 160 (see below)

      b) What is the height of the building?

The height of the building is also the height of the tennis ball before it is launched into the air. This occurs when t=0 so substitute 0 for t and you get:

H(0) = -16(0)2 + 144(0) + 160

The height of the building is 160 feet.

 c) At what time did the ball hit the ground?

The ball hits the ground when the height is 0. Therefore, we are looking for a solution to: -16t2 + 144t + 160 = 0

Use the quadratic formula or put this into a calculator. The solution is t=10 and -1, but only 10 makes sense. Therefore, the ball hits the ground at 10 seconds.

  d) At what time did the ball reach its maximum height?

You can put this into the calculator or you can realize that the maximum height is also

− the vertex. The x-value (‘t’ in this case) is 2

−144

which is (2)(−16) = 4.5.

Therefore, the ball reached its maximum height at 4.5 seconds.

   e) What is the maximum height of the ball?

We calculated the time of the maximum height (4.5 seconds). Therefore, substitute 4.5 into the function to find the maximum height.

-16(4.5)2 + 144(4.5) + 160

The maximum height is 484 feet.
