A cylinder and a cone have the same volume. The cylinder has a radius of 2 inches and a height of 3 inches. The cone has a radiu

jolli1 [7]

ANSWER

$h= 4in.$

EXPLANATION

The volume of a cylinder is calculated using the formula;

$v = \pi \: {r}^{2} h$

It was given that, the cylinder has a radius of 2 inches and a height of 3 inches.

This implies that,

$v = \pi \times {2}^{2} \times 3$

$v =12 \pi$

The volume of a cone is given by

$v = \frac{1}{3} \times \pi {r}^{2} h$

The cone has a radius of 3 inches:

$v=\frac{1}{3} \times \pi \times {3}^{2} h$

$v=3 \pi h$

The two volumes are the same:

This implies that,

$3 \pi h = 12\pi$

Divide both sides by 3π

$h= 4in$

Hal is asked to write an exponential function to represent the value of a $10,000 investment decreasing at 2% annually. What

jek_recluse [69]

Answer:

0.98

Step-by-step explanation:

The investment starts at $10,000.

$10,000 is 100% of the investment.

In the first year, it loses 2% of its value. That means that after 1 year, the value of 100% of $10,000 is decreased by 2% of $10,000.

100% - 2% = 98%

After the first year, the investment is worth 98% of the original value.

98% as a decimal is 0.98

Answer: 0.98

Write an equation of the line in slope- intercept form

gavmur [86]

Answer:

$a)\ y=-\frac{1}{3}x$

Step-by-step explanation:

Slope (m) form: $\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{1-0}{-3-0} \\\\m=\frac{1}{-3} \\\\m=-\frac{1}{3}$

$y=mx+b\\y=-\frac{1}{3}x +b$

(0, 0)

$y=-\frac{1}{3}x +b\\0=-\frac{1}{3}(0) +b\\0=0+b\\0=b$

$y=-\frac{1}{3}x +0\\y=-\frac{1}{3}x$

Check your answer:

$y=-\frac{1}{3}x \\1=-\frac{1}{3}(-3)\\1=-1$

This statement is true

Hope this helps!
