Is it possible to combine multiple discounts that are less than 100% off so that an item is 100% off and essentially free?

Mkey [24]

Sort of, say you take 99% off of something that is $100. You will end up paying $1. Then if you take another 99% off, you wil pay $0.01. Takig another 99% off will give you $0.001, but money only goes to two decimal points, so its free from a money standpoint, but there is still a cost.

A spherical party balloon is being inflated with helium pumped in at a rate of 10 cubic feet per minute. How fast is the radius

Anastaziya [24]

Answer:

The radius is growing at a rate of $\frac{dr}{dt} = \frac{10}{4 \pi} = 0.795$ ft per minute.

Step-by-step explanation:

From the information given we know that

$\frac{dV}{dt} = 10$

And we know as well that .

$V = \frac{4}{3} \pi r^3$

Since everything is changing with the time we can compute the implicit derivative and we would get that

$\frac{dV}{dt} = 10 = 4\pi r^2 \frac{dr}{dt}$

We are told that we are looking for how fast is the radius growing at the instant when the radius has reached 1 ft, therefore $r = 1.$

And when we solve for $\frac{dr}{dt} = \frac{10}{4 \pi} = 0.795$
