In six months the membership at a fitness center went from 3,500 to 4,200. what was the percent of increase in the membership?

slega [8]

It is definitely C: 20%

Subtract the original value from the new value, then divide the result by the original value then multiply the result by 100 and it will give you the answer

$\frac{4200 - 3500}{3500} \times 100$
$\frac{700}{3500} \times 100$
$0.2 \times 100 = 20\%$

Answer:

α = 27.9794744° ≈ 28.0 m (nearest tenth)

Step-by-step explanation:

Step 1:

Opposite (O) = 42.5 (the side opposite to the reference angle, α)

Adjacent (A) = 80

Hypotenuse (H) = the longest side opposite to the right angle

2. We are given the adjacent (A) and opposite (O) lengths, we would use TOA. Which is:

Tan α = Opp/Adj

Plug in the values

Tan α = 42.5/80

3. Make α stand alone

α = $tan^{-1}(\frac{42.5}{80})$

4. α = 27.9794744° ≈ 28.0 m (nearest tenth)

Answer:

(b) 3 terms, degree 10

Step-by-step explanation:

When simplifying polynomials, the first thing you look at is the exponents of the variables in each term. (The terms are separated by + or - signs.) Only terms with the same set of exponents can be combined.

When considering the degree of the polynomial, you look at the sum of exponents of the variables in each term. That sum is the degree of the term. The degree of the polynomial is the highest of the degrees of the terms.

<h3>exponents and degree</h3>

The four terms have variables s and t. If we write the exponents of those variables as an ordered pair, we will have one ordered pair for each term:

5s⁶t² ⇒ (exponent of s, exponent of t) ⇒ (6, 2); degree = 6+2 = 8

6st⁹ ⇒ (1, 9); degree = 1+9 = 10

-8s⁶t² ⇒ (6, 2); degree 6+2 = 8 (this is a like term to the first term)

-6t⁷ ⇒ (0, 7); degree 0+7 = 7

The degrees are 8, 10, 8, 7, so the highest degree is 10. This is the degree of the polynomial.

<h3>combining terms</h3>

We can only combine the terms containing s⁶t². Doing that gives ...

(5 -8)s⁶t² +6st⁹ -6t⁷ = -3s⁶t² +6st⁹ -6t⁷ . . . . . three terms

In "standard form", the terms are written in order of decreasing degree:

6st⁹ -3s⁶t² -6t⁷ . . . . . . 3 terms, degree 10
