Answer:
1
Step-by-step explanation:
We pick two points on the line and use the slope formula
Two points ( 0,2) and ( 1,3)
m = ( y2-y1) / ( x2-x1)
= ( 3-2) /( 1-0)
= 1 /1
= 1
When the ball hits the ground, h will be 0 so set up the equation
-16t^2+16t+32=0
divide all by -16 to simply the equation
t^2-t-2=0
(t-2)(t+1)=0
t=2 t=-1
you can’t have -1 second
so the answer is it takes 2 seconds for the ball to hit the ground

Step-by-step explanation:
2 right triangles (2a) make a square
4 right triangles (4a) make a rectangle
2 right triangles (2a) make a bigger triangle
This alone can help with most of them by combining these together and adding/removing semicircles.
