When the height is 0 that is when it hits the ground
solve
0=-16t²+25x+3
cant factor so use quadratic formula
for
0=ax²+bx+c

so for
0=-16t²+25t+3
a=-16
b=25
c=3
so



it has to be a positive time
so it will hit the ground after

seconds
Answer:
the answer is 3 and 9. 9 is 6 greater than 3 and 9 squared and 3 squared added up give you 90.
a.
has an average value on [5, 11] of

b. The mean value theorem guarantees the existence of
such that
. This happens for

Answer:
x = 3
Step-by-step explanation:
x + 3 = 4x - 6
add 6 to both sides
x + 9 = 4x
subtract x from both sides
9 = 3x
divide 3 from both sides
x = 3
