First calculate the time it takes to reach the building using the x-component of the velocity.

t = 57.6 m / (42.7 m/s * cos35.2) = 1.65 s

 

Then we calculate the height y using the y-component of the velocity:

y = (42.7 m/s * sin35.2) * 1.65 s – 0.5 (9.81 m/s^2) (1.65 s)^2

<span>y = 11.26 m</span>

(8x – 20)-16 =10x+51
Lemur [1.5K]

When solving this equation, you get the answer as -43.5.

To solve, we simply need to collect like-terms and then rearrange to get x on one side and numbers on the other:

(8x - 20) - 16 = 10x + 51

8x - 36 = 10x + 51

- 8x

-36 = 2x + 51

- 51

-87 = 2x

÷ 2

-43.5 = x

I hope this helps!

notka56 [123]

Answer:

  (-4, -2)

Step-by-step explanation:

  A = (-1, 2)

Add (-3, -4) to that and you get ...

  A' = (-1-3, 2-4) = (-4, -2) . . . . matches the last choice

__

The translation function has the effect of moving the point left 3 and down 4. You can count grid squares on the graph to see that A' ends up at (-4, -2).
