A ball is dropped from a 75 foot tall tower, and the height of the ball (in feet) can be represented by the equation h = —16t^2

damaskus [11]

Answer:

The ball will take approximately 2.165 seconds.

Step-by-step explanation:

The height of the ball is represented by the function $h(t) = -16\cdot t^{2}+75$ , the time taken by the ball to hit the ground is a value of $t$ such that $h(t) = 0$ , we proceed to solve the following equation for $t$ :

$-16\cdot t^{2}+75 = 0$ (1)

$16\cdot t^{2} = 75$

$t = \sqrt{\frac{75}{16} }$

$t \approx 2.165\,s$

The ball will take approximately 2.165 seconds.

2x + 2 y = -2<br> 3x - 2y = 12

Serggg [28]

Answer:

x=2 and y=-6 aka. (2,-6) which is the point of intersection

Step-by-step explanation:

Use elimination to cancel out y by adding the equations:

5x=10

x=2

Plug x=2 into one of the equations and find y:

2(5)+2y=-2

10+2y=-2

2y=-12

y=-6

Therefore, x=2 and y=-6
