The volume of a cylinder is 2,200π cubic inches. The diameter of the circular base is 10 inches. what is the height of the cylin

umka21 [38]

If the diameter of the cylinder's base is 10, then the radius is half that, or 5.

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h\qquad 
\begin{cases}
r=radius\\
h=height\\
------\\
r=5\\
V=2200\pi 
\end{cases}\implies 2200\pi =\pi (5)^2h
\\\\\\
\cfrac{2200\pi }{\pi (5)^2}=h\implies \cfrac{2200}{25}=h\implies 88=h$

Use each model to predict the life expectancy of residents of a country for which the average annual income is $80,000

Mandarinka [93]

The life expectancies of residents of a country for which the average annual income is $80,000 for the three models are 12309.9352, 172.2436 and 4828.1393

The life expectancies of the models are given as:

$y =69.9352 + 0.1530\times (income)$ --- model 1

$y =4.2436 + 0.0021\times (income)$ --- model 2

$y =4.1393 + 0.0603\times (income)$ --- model 3

Given that the average annual income is $80,000;

We simply substitute 80000 for income in the equations of the three models.

So, we have:

Model 1

$y =69.9352 + 0.1530\times (income)$

$y =69.9352 + 0.1530\times 80000$

$y =12309.9352$

Model 2

$y =4.2436 + 0.0021\times (income)$

$y =4.2436 + 0.0021\times 80000$

$y =172.2436$

Model 3

$y =4.1393 + 0.0603\times (income)$

$y =4.1393 + 0.0603\times 80000$

$y =4828.1393$

Hence, the life expectancies are 12309.9352, 172.2436 and 4828.1393

Suppose a population has a doubling time of 25 years. By what factor will it grow in 25 years? 50 years? In 100 years?

rewona [7]

Answer:

2,4, and 8.

Step-by-step explanation:

If the population has a doubling time of 25 years, that means that in 25 years the population will double. So for 25 years, the factor will be 2. For 50 years, the factor would be 2x2, which is 4. For 100 years, it is 4x2 which is a scale factor of 8.

If A = –2p + 7 and B = p2 + 3p – 5, find an expression that equals A – 3B in standard form.

Sophie [7]

Answer:

-3p^2 - 11p + 22

Step-by-step explanation:

A - 3B becomes (-2p + 7) - 3*(p^2 + 3p - 5).

Perform the indicated multiplication, obtaining:

(-2p + 7) - 3p^2 - 9p + 15, and then:

-2p + 7 - 3p^2 - 9p + 15, or (combining like terms):

-3p^2 - 11p + 22
