Given the following table, find the rate of change between f(-1) and f(2). x -1 0 1 2 3 f(x) -2 -1
salantis [7]

Answer:

[f(2) - f(-1)]/3

Step-by-step explanation:

The table is incomplete, so I will answer the question in general terms. The rate of change between f(-1) and f(2) is computed as follows:

rate of change = [f(2) - f(-1)]/[2 - (-1)] = [f(2) - f(-1)]/3

To complete the calculation you need to replace the values of the function at x = 2 and x = -1, and compute the result.

Find the area and perimeter of the square 6 meters
Mkey [24]
<h2>AREA</h2>

The formula for finding area of a square is:

length \times width

In a square, all the sides are the same. Each side is 6 meters long. Plug in 6 to the formula.

length \times width \rightarrow 6 \times 6

Multiply:

6 \times 6 = 36

The area of the square is 36 m²

<h2>PERIMETER</h2>

Perimeter is the distance around a shape. To find perimeter, you have to add all all the side lengths. The formula for finding perimeter is:

2(l) \times 2(w)

Remember that squares have 4 sides, and all length(s) and width(s) measure the same. The length and width measure the same. Plug in the numbers into the formula:

2(l) + 2(w) \rightarrow 2(6) + 2(6)

Simplify:

2(6) + 2(6) = 12 + 12

Add:

12 + 12 = 24

The perimeter of the square is 24 m
