So start off with the shipping fee which is $5 per cd and you have 4 cds so 5x4=$20 That’s how much shipping cost. Then you would subtract that from the total. $68.96-$20=48.96 Then divide that buy 4 because that’s how many cds you have. 48.96/4=12.24. That means each cd is $12.24 :)

Can the function f(x) = x²-4x+4 be factored? If so, write the factored form.​
Colt1911 [192]

Answer:

f(x) = (x - 2)²

Step-by-step explanation:

f(x) = x² - 4x + 4 is a perfect trinomial.

You know a trinomial is perfect when double the square root of the first term multiplied by the square root of the last term equals the middle term.

As an equation, a trinomial in the form ax² + bx + c = 0:

2√a√c = b is a perfect trinomial.

Perfect trinomial are factored in this form:

(√a ± √c )(√a ± √c ) = (√a ± √c )²

Whether the sign is + or - depends on if the middle term is positive or negative.

In f(x) = x²-4x+4, the middle term is a negative.

The square root of the first term is 1.

The square root of the second term is 2.

The factored form is (x - 2)²

Finding the average rate of change of g(z) =4x^2_5 between the points( -2,11) and (2,11
krok68 [10]

Answer:

The average rate of change of g(z) =4x^2_5 between the points( -2,11) and (2,11) is 0.

Step-by-step explanation:

Given a function y, the average rate of change S of y=g(z) in an interval  (z_{s}, z_{f}) will be given by the following equation:

S = \frac{g(z_{f}) - g(z_{s})}{z_{f} - z_{s}}

In this problem, we have that:

g(z) = 4z^{2} - 5

Between the points( -2,11) and (2,11).

So z_{f} = 2, z_{s} = -2

g(z_{f}) = g(2) = 4*(2)^{2} - 5 = 11

g(z_{s}) = g(-2) = 4*(-2)^{2} - 5 = 11

So

S = \frac{g(z_{f}) - g(z_{s})}{z_{f} - z_{s}} = \frac{11 - 11}{2 - (-2)} = \frac{0}{4} = 0

The average rate of change of g(z) =4x^2_5 between the points( -2,11) and (2,11) is 0.

What is equivalent to 24/16
gulaghasi [49]
We can convert 24/16 to a mixed number. It will be equivalent to 24/16.

24/16
24 ÷ 16 = 1.5
16 can go in to 24 once.
24 - 16 = 8 

1 = whole number
8 = numerator 
16 = denominator
 
Lets write our mixed number:-

1 \frac{8}{16}

This can be simplified ^^^^

\frac{8/8}{16/8} = \frac{1}{2}

So, our old mixed number simplified is 1 \frac{1}{2}

So, 24/16 is equivalent to 1. 1 \frac{8}{16}, 2. 1 \frac{1}{2}

Hope I helped ya!!! xD
