Answer:

Step-by-step explanation:

A point of the function g(x) is known: (1, 5)

The proper function is

$g(x)=5x^{2}$

Demonstration calculating g(1)

$g(1)=5(1)^{2} =5(1)=5$

The point (1, 5 ) belongs to this function

Hope this helps

kia thinks she can make her new product for $5.80. She plans to sell for $12. what is her percent mark up?

gavmur [86]

First, count the difference of the cost production and the selling cost
difference = 12 - 5.8
difference = 6.2

Second, transform the difference to percentage
percentage = difference/product cost × 100%
percentage = 6.2/5.8 × 100%
percentage = (620/5.8) %
percentage = 106.9%

The mark up cost is 106.9%

Which of the following is written as a rational function?

Brrunno [24]

We have to identify the rational function among the given functions.

Rational function is a function that is the ratio of two polynomials. It is rational because one polynomial is divided by the other polynomial, like a ratio.

1. Consider the first function $G(x)= -2x$ , since it is not a function that is the ratio of two polynomials. So, it is not a rational function.

2. Consider the second function $P(x)= 3x+4$ , since it is not a function that is the ratio of two polynomials. So, it is not a rational function.

3. Consider the third function $Q(x)= x^2-8x+1$ , since it is not a function that is the ratio of two polynomials. So, it is not a rational function.

4. Consider the fourth function $F(x)= \frac{x+2}{5x}$ , since it is a function that is the ratio of two polynomials (x+2) and (5x). So, it is a rational function.
