Answer:
31.9secs
6,183.3m
Step-by-step explanation:
Given the equation that models the height expressed as;
h(t ) = -4.9t²+313t+269
At the the max g=height, the velocity is zero
dh/dt = 0
dh/dt = -9,8t+313
0 = -9.8t + 313
9.8t = 313
t = 313/9.8
t = 31.94secs
Hence it takes the rocket 31.9secs to reach the max height
Get the max height
Recall that h(t ) = -4.9t²+313t+269
h(31.9) = -4.9(31.9)²+313(31.9)+269
h(31.9) = -4,070.44+9,984.7+269
h(31.9) = 6,183.3m
Hence the maximum height reached is 6,183.3m
Answer:
Yes, that is correct.
Step-by-step explanation:
a would always have to be greater than b since you're just multiplying each variable by itself.
Answer:
50yds²
Step-by-step explanation:
area of a triangle equals base times height divided by 2
a=20*5/2
a=100/2
a=50yds²
Hi there....
-8f > 56
Divide both sides by -8
-8f/-8 > 56/-8
f < -7
The correct option is : B
