Q1
r = (2A/θ)^.5 = ((14/(1/8))^.5 = 10.583 ft <--------

q2
θ = 2A/r^2 = 2*3/7^2 = .122 rad <--------

Here, θ/360 * πr² = 69
θ/360 * 3.14 * (14)² = 69
θ/360 * 615.75 = 69
θ = 69*615.75 /360
θ = 40.36

In short, Your Answer would be 40.36 degrees

Hope this helps!

Roman created the following table to represent the balance of his loan, y, over a period of months, x. The equation for the line
Ronch [10]

Answer: extrapolation, and 25 months

Step-by-step explanation:

I took the Plato test and got it right, but if you want to know. Interpolation means based on the numbers given you could see the answer, extrapolation means you have to go farther than the last plot point given to get your answer. Which you do since it does not go past 12 months.

The second answer you can roughly get by pluging in each of the choices in the equation for x

For example: y=-200.22(25)+5015.20

That should give you an answer pretty close to zero so there is your answer

Solve the equation: 5 + 2(3 + 2x) = x + 3(x + 1)
Ann [662]

Answer:

No solutions

Step-by-step explanation:

In this question, you would be solving for x.

Solve:

5 + 2(3 + 2x) = x + 3(x + 1)

Use the distributive property.

5 + 6 + 4x = x + 3x + 3

Combine like terms.

11 + 4x = 4x + 3

Subtract 4x from both sides.

11 = 3

Since we don't have an "x value", there are no solutions.

"No solutions" would be your answer.
