Answer:

-1/6

Step-by-step explanation:

First find the slope of the line through the points

m = (y2-y1)/(x2-x1)

    = (-4-8)/(1-3)

     = -12/-2

      =6

Now we need to find the slope of the line that is perpendicular

Perpendicular lines multiply to -1

6 * mp = -1

mp = -1/6

Paul orders 3 different sizes of pizzas. Each pizza is cut into equal-sized slices as described in the table. Put the pizzas in
Elza [17]

The area of a slice from smallest area to largest area is given by:

  1. Pizza 1 (32π in²).
  2. Pizza 2 (32.7π in²).
  3. Pizza 3 (36π in²).

<h3>What is the area of a circle?</h3>

The area of a circle can be defined as the total space occupied or region enclosed by a circle within its boundary, and in a two-dimensional plane.

<h3>How to calculate the area of a circle?</h3>

Mathematically, the area of a circle is calculated by using this formula:

Area = πr²

<u>Where:</u>

r is the radius of a circle.

For Pizza 1, we have:

Area = π × 16²

Area = π × 256

Area = 256π in².

Area of a slice = 256π/8

Area of a slice = 32π in².

For Pizza 2, we have:

Area = π × 14²

Area = π × 196

Area = 196π in².

Area of a slice = 196π/6

Area of a slice = 32.7π in².

For Pizza 3, we have:

Area = π × 12²

Area = π × 144

Area = 144π in².

Area of a slice = 144π/4

Area of a slice = 36π in².

In conclusion, we can infer and logically deduce that the area of a slice from smallest area to largest area is given by:

  1. Pizza 1 (32π in²).
  2. Pizza 2 (32.7π in²).
  3. Pizza 3 (36π in²).

What is the percent of increase for a population that changed from 438,000 to 561,000?
BARSIC [14]

New number - original number

561,000 - 438,000 = 123,000.

Increased number divided by the original number

123,000 ÷ 438,000 = 0.28

Multiply by 100

0.28 x 100 = 28%

The percentage increase would be 28%
