The correct option is: B. 
<u><em>Explanation</em></u>
<u>The general form of growth equation</u> is: 
, where A = final amount, P = initial amount, r = growth rate in decimal form and t = time duration
Here, the speed of the rocket at the beginning was 5,000 kilometers per hour and at the end will be 25,000 kilometers per hour. The speed increases at a rate of 4.3% per minute.
That means, 
Now <u>plugging these values into the above equation</u>, we will get......
So, the equation that could be used to determine the time for the speed of the rocket to reach 25,000 kilometers per hour will be:

Answer:
B. 427
Step-by-step explanation:
The median is the middle number. When you cross out numbers on the list you end up with 420 and 434. We take the average:
(420 + 434)/2 = 427
Answer:
See below
Step-by-step explanation:
I'm not sure if there are any specific instructions on how these answers are supposed to be written, but here's my best shot:
1. U
2. XZ, VY
3. VU, WU
4. XY, ZY
5. ⊙U
6. XZ, VY (they are diameters but also intersect)
7. VY = 10 cm, WU = 5 cm
8. Diameter (of larger circle)
9. Diameter (of smaller circle)
10. Radius (of larger circle)
11. Radius (of smaller circle)
