3 0

Answer:

see below

Step-by-step explanation:

h(t) = -16t^2 + 256

h(4) =0

This means at t=4 second the height above the ground is 0

At 4 seconds, the penny will hit the ground

Which of the following describes the graph of y=\sqrt(-4x-36) compared to the parent square root function?
borishaifa [10]

Answer:

Option D - Stretched by a factor of 2, reflected over the y-axis, and translated 9 units left.

Step-by-step explanation:

Given : The function y=\sqrt{-4x-36}

To find : Which of the following describes the graph of y=\sqrt{-4x-36}compared to the parent square root function?

Solution :

First we simplify the given expression

y=\sqrt{-4x-36}

y=\sqrt{4(-x-9)}

y=2\sqrt{-(x+9)}

→When we see the original square root function minus was taken outside x and 9 was added from x and 2 was multiplied to the entire function.

  • Multiplying 2 in the function will give you the stretched by a factor of 2.
  • g(x)=\sqrt{-x} shows the reflection about y-axis i.e, (x,y)→(-x,y).
  • If f(x)→f(x+b) then function is shifted left by unit b

        ⇒ g(x))→g(x+9) then function is shifted left by unit 9

Therefore, The graph of was stretched by a factor of 2, reflected over the y-axis, and translated 9 units left to obtain the graph of the function .

So, Option D is correct.
