Answer:
72.17 m to the nearest hundredth.
Step-by-step explanation:
It is sin not cos.
We use the Sine Rule to do this
a / sin A = b / sin C = c / sin C.
Here we have:
100 / sin 49 = x / sin 33
x = 100 * sin 33 / sin 49
= 72.17 m.
the answer is 7 because all of the other numbers opposites aren't negative
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
The number with the same value will be 40 because 10 tens make 100 and 4 tens make 40 so it wili be 140
