Answer:
V = 500 pi in^3
or approximately 1570 in ^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
The diameter is 10. so the radius is d/2 = 10/2 =5
V = pi (5)^2 * 20
V = pi *25*20
V = 500 pi in^3
We can approximate pi by 3.14
V = 3.14 * 500
V = 1570 in ^3
The value of the trigonometric ratio, Cos C is 5/13. The answer is A.

The power 0 only affects the x. x^0 = 1
-2 * 1 = -2
25
Here everything inside the brackets is affected by the 0.
(11abx)^0 = 1 There is nothing left over.
26
(xy)^0 = 1
(pq)^0 = 1
1 - 1 = 0
Answer:
19 days
Step-by-step explanation:
Given
--- initial
-- rate
Required
Days when the fish gets to 30
The function is exponential and as such it follows;

Where x represents the number of days and y the number of fishes
Because the fishes decreases;

So, we have:

Express as decimal


In 



So, we have:

Divide both sides by 150

Take log of both sides

Apply law of logarithm

Make x the subject




<em>Hence, it takes approximately 19 days</em>
