Take the root of both sides and solve.
c = - 7 sqr root 5
c = -1.258
Answer: D (both the sum and the product).
Step-by-step explanation:
Let's add: 4 + sqrt5 will still seem irrational.
Let's multiply: 4*sqrt5 = 4sqrt5, which is irrational.
Answer:
197.625
Step-by-step explanation:
6324/32 = 1581 =8
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:
an = 2/5 * (5) ^ (n-1)
Step-by-step explanation:
The common ratio is 5
(That is the number we multiply by)
The formula is
an = a1 (r) ^ (n-1)
an = 2/5 * (5) ^ (n-1)
