Take west to be the positive direction. The height of a sloped roof above the place where you stand is 12
feet. If you move 3 feet west, the height is 10 feet. What is the slope?

Given:

Take west to be the positive direction. The height of a sloped roof above the place where you stand is 12  feet. If you move 3 feet west, the height is 10 feet.

We need to determine the slope.

Let x denote the standing place.

Let y denote the height.

Writing the given as coordinates, we get;

(0,12) and (3,10)

Slope:

The slope can be determined using the formula,

Substituting the coordinates (0,12) and (3,10), we have;

Thus, the slope is

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
