Create a table of values for the function f(x) = (1/3)^–x
mr_godi [17]

Answer:

See the explanation

Step-by-step explanation:

The function given to us is:

f(x) = (1/3)⁻ˣ

We can convert the negative power into positive one by interchanging the numerator and denominator.

f(x) = (3/1)ˣ

f(x) = 3ˣ

Substitute value for x= -3 , -2, -1, 0, 1, 2, 3

f(-3) = 3⁻³ = 0.037

f(-2) = 3⁻² = 0.111

f(-1) = 3⁻¹ = 0.333

f(0) = 3⁰ = 1

f(1) = 3¹ = 3

f(2) = 3² = 9

f(3) = 3³ = 27

f(4) = 3⁴ = 81

and so on

The table of the found values of f(x) or y for the corresponding values of x, along with their graph is given below.

A rectangle has a length of 8 inches and a width of 7 inches. The perimeter of the rectangle is ___ inches.
natta225 [31]

Answer: 30 inches.

Step-by-step explanation:

We need to use the formula for calculate the perimeter of a rectangle. This is:

P=2l+2w

Where "l" is the length and "w" is the width.

In this case, we know that the lenght and the width of this rectangle are:

l=8\ in\\\\w=7\ in

Therefore, substituting values into the formula, we get that the perimeter of this rectangle is:

P=2(8\ in)+2(7\ in)\\\\P=30\ in
