Answer:
0.5 seconds
Step-by-step explanation:
Equation: h(t) = -5t²+5t=10
Where h(t) is in meter, t is in seconds.
The driver will reach maximum height when d[h(t)]/d(t) = 0
From the equation,
d[h(t)]/d(t) = -10t+5
Therefore,
-10t+5 = 0
Solve for t
-10t = -5
10t = 5
t = 5/10
t = 0.5 seconds.
Hence the height will be maximum in 0.5 seconds.
c. 11
it's c because if they start with 5 then
1=5
2=6
3=7
4=8
5=9
6=10
7=11
Answer:
0.82 ≤ x ≤ 0.89
Step-by-step explanation:
hope this helps, pls mark brainliest :D
X^2-6x+9
use fiol then add like terms
-(4 1/5)
5(4)+1 = 21
Thus the answer would be -21/5
