Answer:

A and B are functions

Step-by-step explanation:

for A, none of the x's repeat which makes it a FUNCTION

for B, when it starts with x^2, it will always be a FUNCTION (its a quadratic)

for C, 10 repeats for the x so it is NOT A FUNCTION

Use the grid to create a model to solve the percent problem. 12 is 60% of what number? Enter your answer in the box
Elenna [48]
Is means equal to and of means multiply. So....your equation would be 12=60%x. Now since u can't multiply by a percent, u gotta do 12=.6x. Now divide by .6 so that it cancels out. Your answer is 20. Hope this helps!

Is a tray with a circumference of 32 inches is big enough to
yKpoI14uk [10]

Answer:

Yes

Step-by-step explanation:

Circumference formula is C=2 pi r, if you divide the pizza by 2 to get the radius,5, then input it into the formula to get 31.41592654, and since this number is smaller than 32 it will fit. If 10 is the radius it will not fit.

A 6-inch candle burns down in 12 hours. After how many hours will it have burned<br> 4 inches?
Zielflug [23.3K]

Answer:

8 hours

Step-by-step explanation:

Let's first find how many inches the candle would have burned in 1 hour.

6 in:12 hours

x: 1 hour

We can divide 12 by 12 to get 1. This means we need to divide 6 by 12 to get x

x=1/2 inches

1/2 inches:1 hour

4 inches: x hours

We divide 4 by 1/2 to get 8. 1/2*8=4. This means...

x=1 hour*8=8 hours

P(x)=x^3+2x^2-4x-8 how do you factor this polynomial function
Wewaii [24]
<h2>Steps:</h2>

So for this, I will be factoring by grouping. Firstly, factor x³ + 2x² and -4x - 8 separately. Make sure that they have the same quantity inside of the parentheses:

p(x)=x^2(x+2)-4(x+2)

Now we can rewrite it as:

p(x)=(x^2-4)(x+2)

However, we aren't finished factoring yet. The first factor, x² - 4, can be factored further using the difference of squares. The difference of squares goes by the formula here: x^2-y^2=(x+y)(x-y) . In this case:

x^2-4=(x+2)(x-2)\\p(x)=(x+2)(x-2)(x+2)

<h2>Answer:</h2>

<u>In short, the answer is p(x)=(x+2)(x-2)(x+2)\ \textsf{OR}\ p(x)=(x-2)(x+2)^2</u>
