Answer:

9^4

Step-by-step explanation:

If you wanted to change it to a number with an exponent yourself, you would count how many 9's there are and that would the the exponent. Since there's 4 9's, the exponent is 4

disa [49]

Freya begins started with 200 yards.

Freya then increased her distance by adding five yards a day for two days.

x = 200 + (n - 1)5.

<em>[x = The distance Freya sprints on day 21]</em>

x = 200 + (21 - 1)5

x = 200 +  (20) 5 = 300 yards

Please help me- thank you

Answer:
(2^2)(z^7)

Explanation:
The quotient rule states that if two powers have the same base and are on opposite places of a fraction (one is on the numerator, the other on the denominator), you subtract the exponents.

First looking at the powers with the bases of 2, 2^8 is the numerator and 2^6 is the denominator. When we subtract 8-6 we get 2, so 2^8/2^6 would simplify to 2^2.

Then, we look at the powers with the base of z. z^10 is the numerator and z^3 is the denominator. When we subtract 10-3 we get 7, so z^10/z^3 would simplify to z^7.

I hope this helps! Please comment if you have any questions:)

Answer:

A = 12.56 m²

General Formulas and Concepts:

<u>Pre-Alg</u>

  • Order of Operations: BPEMDAS

<u>Geometry</u>

  • Area of a Circle: A = πr²
  • d = 2r

Step-by-step explanation:

<u>Step 1: Define</u>

d = 4 m

<u>Step 2: Find </u><em><u>r</u></em>

  1. Substitute:               4 = 2r
  2. Isolate <em>r</em>:                   2 = r
  3. Rewrite:                    r = 2 m

<u>Step 3: Find Area</u>

  1. Substitute:               A = π(2)²
  2. Substitute:               A = (3.14)(2)²
  3. Evaluate:                  A = (3.14)(4)
  4. Multiply:                   A = 12.56 m²
