The maximum time 1.75 second in case of not having the height:
1. change in ax²+bx+c form⇆ -16t²+56t-40=h
h=(8-8t)(2t-5)
h=16t-40-16t²+40t
h=-16t²+56t-40
2. t max=-b/(-2a)=-56/(-2×-16)=1.75 second

1) Since these triangles are congruent, then we can write out the following for congruent triangles have congruent sides:

2) Still based on that principle, we can plug v=2 into any of those formulas to get the measure of QS and TV. So let's pick the simpler one:

As we can see these segments are congruent.
Answer:
Distance is 8.485
Midpoint is (3,4)
Step-by-step explanation:
Use the points (-1,7) and (5,1)
Insert them into the equation and solve for D

Insert points into second equation to find midpoint

Answer:
1) An triangle
2)Area is the same
3) Length times width then times 1/2
4)To find the polygon's area using the circle's measurement you us pi times radius squared(to find the circles area which is the same as the polygon's area)
HOPE THIS HELPS :)
