Answer:

Step-by-step explanation:

This is a straight forward proportion.

9 hours = 35 dollars

1 hour = x                      

9:1::35:x                                                              Cross multiply

9 hour * x = 1 hour * 35 dollars.                        Divide by 9

9 hour / 9 hour x = 1 hour   35 dollars/9 hour

x = 35/9

x = $3.89 rounded.

Which diagram best represents the following expression?<br> 2(n - 1) + 1
joja [24]
<h2>Explanation:</h2>

Here we have the following expression:

2(n - 1) + 1

So we can rewrite this as follows:

a_{n}=2(n - 1) + 1

So this is an arithmetic series whose general form is given by:

a_{n} = a + d(n-1)

Where:

a: \text{is the first term} \\ \\ d: \text{is the difference between the terms, also called "common difference"}

So, for some n-values we have:

a=1 \\ \\ a_{2}=2(2-1)+1=3 \\ \\ a_{3}=2(3-1)+1=5 \\ \\ a_{4}=2(4-1)+1=7 \\ \\ a_{5}=2(5-1)+1=9

From this information, the diagram that best represents the given expression is shown below.

What must be a factor of the polynomial function fx) graphed on the coordinate plane below?
Reptile [31]

See in the explanation

<h2>Explanation:</h2>

Hello! Recall that you need to write complete questions in order to get good and precise answers. However, I'll try to explain this problem in a general way. The definition of polynomial functions states:

A \ \mathbf{polynomial \ function} \ of \ x \ with \ degree \ n \ is \ given \ by:\\ \\ f(x)=a_{n}x^{n}+a_{n-1}x^{n-1}+\ldots +a_{2}x^{2}+a_{1}x+a_{0} \\ \\ where \ n \ is \ a \ nonnegative \ integer \ and \ a_{n}, a_{n-1}, \ldots a_{2}, a_{1}, a_{0} \\ with \ a_{n}\neq 0

Suppose we have the following polynomial function:

f(x)=x^3+x^2-8x-12

If (x-3) is a factor of this polynomial function, we can write f(x) as:

f(x)=\left(ax^2+bx+c\right)\left(x-3\right)

In whose case:

f(3)=0

Evaluating x=3

f(x)=x^3+x^2-8x-12 \\ \\ f(3)=3^3+3^2-8(3)-12 \\ \\ f(3)=27+9-24-12 \\ \\ f(3)=32-32 \\ \\ f(3)=0

So in conclusion:

(x-3) \ is \ a \ factor \ of \ f(x)=x^3+x^2-8x-12

The graph is shown below and is consistent with our conclusion.
