the equation framed in the form of y=kx is  y = 9.6(x) and ,  x as a function of y x=\frac{1}{ 9.6}(y) .

<u>Step-by-step explanation:</u>

Here we have , The amount Lin's sister earns at her part-time job is proportional to the number  of hours she works. She earns $9.60 per hour. We need to find  an equation in the form y=kx  to describe this situation, where x represents the hours she works and y  represents the dollars she earns.Is y a function of x . Also , Write  an equation describing x as a function of y . Let's find out:

Here , Lin's sister earns $9.60 per hour . Let  x represents the hours she works and y  represents the dollars she earns . So , According to question following is the equation framed in the form of y=kx :

⇒ y = 9.6(x)

Yes, y is a function of x , as a straight line with a slope of 9.6

Now ,  x as a function of y :

⇒ \frac{y}{ 9.6}=(x)

⇒ x=\frac{1}{ 9.6}(y)

Therefore , the equation framed in the form of y=kx is  y = 9.6(x) and ,  x as a function of y x=\frac{1}{ 9.6}(y) .

Question - Find each f(c) using synthetic substitution. f(x) =5x 5 + 10x 4 + 3x 3 + 8x 2 – 6x – 3; c = 3
SpyIntel [72]

Answer:

2157

Step-by-step explanation:

The given function is

f(x)=5x^5+10x^4+3x^3+8x^2-6x-3

We want to find f(c) when c=3.

This means the remainder when f(x) is divided by x-3

We perform the synthetic division:

    5     10      3      8       -6      -3

<u>3|         15    75    234    726    2160</u>

    5     25    78    242    720    2157

Therefore the remainder is 2157

You are right

On a map of North America, the scale is:
Zolol [24]
The scale factor as I understand it will just be 1 to 30, inches to miles.

however, in this case it seems to be suggesting a conversion to the same unit, say hmmm let's convert the miles to inches.

\bf 30~\underline{mi}\cdot \cfrac{5280~\underline{ft}}{\underline{mi}}\cdot \cfrac{12~in}{\underline{ft}}\implies \cfrac{30\cdot 5280\cdot 12~in}{1}\implies 1900800~in\\\\&#10;-------------------------------\\\\&#10;\stackrel{in}{1}:\stackrel{mi}{30}\implies \stackrel{in}{1}:\stackrel{in}{1900800}
