From the equation, h(t)=-16t^2+150. You are given the height of the building which is 15ft and you are asked to find the time it takes to fall in seconds.

h(t)=-16t^2+150

15=-16t^2+150

15 – 150 = -16t^2

-135 = -16t^2

t = 2.9 seconds

Tia states that the graph of g(x) = (x – 2)3 + 7 is a translation of 2 units to the left and 7 units up from f(x) = x3. Is Tia’s
Lina20 [59]

Answer:

No.

Step-by-step explanation:

Compare g(x) = (x – 2)^3 + 7 to f(x) = (x - h)^3 + k.  Here, h denotes horizontal translation and k denotes vertical translation.  Translation to the left by 2 units would be (x + 2)^3 + 7.  Translation to the right by 2 units would be (x - 2)^3 + 7.  So, no, Tia's description of horiz. translation is incorrect.

However, her adding 7 does denote a positive vertical translation.

natali 33 [55]

Answer:

  • Graph D

Step-by-step explanation:

According to the question, the correct graph is D.

It's not A because, the ball is thrown after some pause and the ball doesn't roll on the roof, falls immediately.

It's not B or C because the ball goes up after reaching the roof but should fall down.
