Answer:
392
Step-by-step explanation:
1.49×10⁸/3.8×10⁵ = 392

Round by 10,000 is 215,210,000</span>
1. 538 - 247 = ?
2. 8 - 7 = 1
3. You can't subtract 3 and 4, so you have to take number from 5 (turning it into a 4) and then you add a 1 right next to 3 (which makes it 13;13 - 4 = 9
4. 4 - 2 = 2
538 - 247 = 291
So the answer is 291.
You use the slope formula, (y2-y1/x2-x1)
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
