Answer:

(-8, 1), (8, -8) has a negative slope

Step-by-step explanation:

1). y2 - y1 / x2 - x1

7 - 9 / 5 - 6

= 2

2). y2 - y1 / x2 - x1

6 - (-2) / 3 - (-9)

= 2/3

3). y2 - y1 / x2 - x1

-8 - 1 / 8 - (-8)

-9/16

4). y2 - y1 / x2 - x1

-9 - (-8) / -1 - 2

= 1/3

Hi there!

$\huge\boxed{\text{22 cm}}$

We know that:

Area of a rectangle = l × w

The areas are the same, so:

3x · 4 = 6(3x - 2.5)

Simplify:

12x = 18x - 15

Solve for x:

15 = 6x

x = 2.5

Plug in this value of x to find the perimeter of rectangle B:

P = 2l + 2w

l = 6

w = 3(2.5) - 2.5 = 5

P = 2(6) + 2(5) = 22 cm

A right circular cylinder has a height of 2214 ft and a diameter 225 times its height.

Temka [501]

Answer:

Volume is 431288166770775 cubic feet.

Step-by-step explanation:

The height of the cylinder = 2214 ft

Let d be the diameter . Hence, we have

d = 225 × 2214 = 498150 ft

Hence, the radius should be half of diameter.

$r=\frac{d}{2}\\\\r=\frac{498150}{2}\\\\r=249075ft$

The volume of cylinder is given by

$V=\pi r^2h\\\\V=3.14(249075)^2(2214)\\\\V=431288166770775ft^3$

What is the equation for r

Cloud [144]

V = lhr

V ÷ lh = lhr ÷ lh

V/lh = r

r = V/lh

Just divide both sides by what you want removed, leaving behind r.
