Answer:
Last option: Keep the base the same and then subtract the exponents.
Step-by-step explanation:
There is a property called "Quotient of power property".
This property states that if you need to divide two powers with the same base, you must keep the same base and subtract the exponents:
Then, you need to apply this property to the expression to simplify it.
Therefore, you get that the expression simplified is:
Answer:
the surface area will increase 16 feet per minute
Step-by-step explanation:
Allow me to revise your question for a better understanding.
<em>A spherical balloon is inflating with helium at a rate of 64π Start Fraction ft cubed Over min End Fraction ft3 min. How fast is the balloon's radius increasing at the instant the radius is 2 ft? How fast is the surface area increasing? </em>
My answer:
Given that:
(1)
As we know that, the volume of a spherical balloon can be calculated by using the following formula:
where r is the radius
Substitute V into (1), we have:
In this situation, the instant radius is: 2f
So we have:
The radius of the balloon is increasing at a rate of 4 feet per minute
The the surface area has the formula as:
SA1 = 4π
If the radius of the balloon is increasing at a rate of 4 feet per minute, so the
the surface area will increase 16 feet per minute because:
SA2 : 4π = 16 (4π
) = 16 SA1
Hope it will find you well.
