Marta is solving the equation s=2πrh+2πr^2 for h. which should be the result?

Marta_Voda [28]

Answer: First option.

Step-by-step explanation:

Marta needs to subtract $2\pi r^2$ from both sides of the equation:

$s=2\pi rh+2\pi r^2$

$s- 2\pi r^2=2\pi rh+2\pi r^2- 2\pi r^2$

$s- 2\pi r^2=2\pi rh$

Now she needs to divide both sides of the equation by $2\pi r$ , then:

$h=\frac{s- 2\pi r^2}{2\pi r}$

Rewriting:

$h=\frac{s}{2\pi r}-\frac{2\pi r^2}{2\pi r}$

Simplifying, she should get:

$h=\frac{s}{2\pi r}-r$

This matches with the first option.

The gasoline gauge on a van initially read one fourth 1 4 full. when 1010 gallons were added to the tank, the gauge read two th

Serga [27]

It is a 24 gallon tank
at 1/4 full =
6 gallons / 24 gallons = 1/4

after 10 gallons added,
= 16/24
= 2/3 full

So 8 more gallons are needed to fill the tank completely.

At an annual effective interest rate of i, the following are all equal:

Kipish [7]

Answer:

PV = 1414.213562

Step-by-step explanation:

Find:

PV = 8,000*V^(t+3)

Solution:

- Split the the exponent of V into t and 3:

PV = 8,000*V^t*V^3

- We will calculate the V^t and V^3 from information given.

- The present value of 10,000 at the end of 6 years and immediate value of $5,000. De-crypt this statement we have:

10,000*V^6 = 5,000

V^6 = 5,000/10,000

V^6 = 0.5

V^3 = sqrt(0.5)

- Using 2 and 3, De-crypt:

6000*V^t + 56,000*V^2t = 5000

Solving the quadratic in V^t:

V^t = 0.25

- Hence, we have the present value as:

PV = 8,000*V^t*V^3

PV = 8,000*sqrt(0.5)*0.25

PV = 1414.213562
