Answer: 628 cubic feet

Step-by-step explanation: First, find the area of the circle. Using the formula "TTr^2", you can find the area of the circle. Since the diameter is given, and not the radius, divide 10 by 2, and it gives you 5. Now, use the formula. 5 x 5 = 25, and then multiply it by 3.14 which gives you 78.5. Now that we have found the area of the circle, multiply the area by 8 to find the volume of the cylinder. 78.5 x 8 is 628 cubic feet, and that is the volume of the cylinder.

What is this equation in point-slope form?

deff fn [24]

Answer:

y - 2 = $\frac{1}{2}$ (x + 8)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = $\frac{1}{2}$ and (a, b) = (- 8, 2), hence

y - 2 = $\frac{1}{2}$ (x + 8) ← in point- slope form

A construction company is moving large rocks. It takes 3/4 hour to move 12 rocks. The construction company has already moved 60

Luden [163]

First divide the rocks per 3/4 of an hour by 3 and multiply by 4 to get the production per hour. then subtract the already moved rocks from the total job and divide the answer by 16 (the rocks moved per hour) getting the time needed to move the rest

Express 2x^2+8x+3 in the form 2(x+p)^2+q

e-lub [12.9K]

Answer:

2(x + 2)² - 5

Step-by-step explanation:

Given

2x² + 8x + 3

To obtain the required form use the method of completing the square.

The coefficient of the x² term must be 1, thus factor 2 out of 2x² + 8x

= 2(x² + 4x) + 3

add/subtract ( half the coefficient of the x- term)² to x² + 4x

= 2(x² + 2(2)x + 4 - 4) + 3

= 2(x + 2)² - 8 + 3

= 2(x + 2)² - 5

with p = 2 and q = - 5
