Answer:

B) Three inches and some number of feet have a total measurement a of 39 inches. How many feet are there?

Step-by-step explanation:

A is wrong since you add 3, not remove it.

C is wrong because 12 is the one being multiplied, not 3

D is wrong because x has to be the same thing as 12, just how many of it there are.

A tanker truck has overturned and is spilling oil onto the highway. Amazingly, the region covered by the oil spill maintains a p
Sav [38]

Answer:

The radius of the oil spill growing at 2 feet per minute

Step-by-step explanation:

Area of a circle is

A=\pi r^2

Differentiating A with respect to r,

\dfrac{dA}{dr} = 2\pi r

When A=100\pi,

100\pi = \pi r^2

r = 10

The rate of growth of the spill is

\dfrac{dA}{dt} = 40\pi

This is equivalent to

\dfrac{dA}{dt} = \dfrac{dA}{dr} \times \dfrac{dr}{dt}

\dfrac{dr}{dt} = \dfrac{dA}{dt}/\dfrac{dA}{dr} = \dfrac{40\pi}{2\pi r} = \dfrac{20}{r}

\dfrac{dr}{dt} = \dfrac{20}{10} = 2

Find the sum of this infinite geometric series: 4 - 2.88 + 2.0736- 1.492992+...
kirza4 [7]
Let r be the common ratio between terms. Then

-2.88=4r\implies r=-0.72

Now denote the nth partial sum of the series by

S_n=4-2.88+2.0736-1.492992+\cdots+4(-0.72)^{n-1}+4(-0.72)^n

Multiply both sides by -0.72, then subtract from the above to get

S_n-(-0.72S_n)=4-4(-0.72)^{n+1}
1.72S_n=4(1-(-0.72)^{n+1})
S_n=2.32558(1-(-0.72)^{n+1})

As n\to\infty, you're left with

S_\infty=2.32558
