Answer:

21x - 42, see below :)

Step-by-step explanation:

Hello!

We know that f(x) is equal to 3x - 6

We want to know what 7 * f(x) is so we should first substitute f(x) for 3x - 6

7 * f(x)

7(3x-6)

We use distributive property to open the parenthesis:

7 * 3x + 7 * -6

21x - 42

Answer:

21x - 42

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Distributive Property

<u>Algebra I</u>

  • Function Notation

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 3x - 6

7f(x)

<u>Step 2: Find</u>

  1. Substitute:                    7f(x) = 7(3x - 6)
  2. Distribute 7:                  7f(x) = 21x - 42

Given the explicit expression f (n) = 5n - 2, write a set showing the sequence, and write a recursive expression.
denpristay [2]

Answer:

f(n) = 5 + f(n - 1)

Step-by-step explanation:

Given

f(n) = 5n - 2

Required

Write a recursive expression

f(n) = 5n - 2

When n = 1

f(1) = 5 * 1 - 2 = 5 - 2 = 3

f(1) = 3

When n = 2

f(2) = 5 * 2 - 2 = 10 - 2 = 8

f(2) = 8 can be rewritten as

f(2) = 5 + 3

Substitute 3 for f(1)

f(2) = 5 + f(1)

Express 1 as 2 - 1

f(2) = 5 + f(2-1) ----- (1)

When n = 3

f(3) = 5 * 3 - 2 = 15 - 2 = 13

f(3) = 13 can be rewritten as

f(3) = 5 + 8

Substitute 8 for f(2)

f(3) = 5 + f(2)

Express 2 as 3 - 1

f(3) = 5 + f(3 - 1)  ------ (2)

Write out (1) and (2)

f(2) = 5 + f(2-1)

f(3) = 5 + f(3 - 1)

Replace 2 and 3 with n in both cases; This gives

f(n) = 5 + f(n - 1)

Hence;

The recursive is f(n) = 5 + f(n - 1)

Pls help me with this problem. Also the answer has to be in terms of pi
katovenus [111]
Answer: 25pi
Explanation: area = piR^2 so 10(radius)^2 = 100pi, only 1/4 of the circle is there so divide the area found (100pi) by 4 to find the one quarter of the circle.
