Step 1: Define
f(x) = 3x³ + 8x - 2
k(x) = 4x
k(f(x)) is x = f(x)

Step-by-step explanation:
The x- intercepts are where the graph intersects with the x- axis.
Here, there are 2 points where the graph crosses the x- axis, that is

A pot holds 16 gallons of soup. A server will empty the pot into one pint containers
How many containers will the server fill?
Answers
Answer:
The server will fill 128 containers.
Step-by-step explanation:
1 gallon = 8 pints
In order to find out how many pints is 16 gallons, we need to multiply 16 by 8.
16 x 8 = 128 pints
If each container can only hold one pint of soup, and the pot hold 16 gallons of soup, than the server will fill 128 containers.

y = 8
y^2 + 15^2 = x^2
64 + 225 = x^2

if x < 81,000
c(x) =
{
if 81,000 < x < $1,200
if x > $1,200
Answers
Answer:
The answer is below
Step-by-step explanation:
Let x represent the profit made from sales and c(x) the commission based on sells. If the profit is less then $1000,they 21%, hence:
if x < 1000, c(x) = 0.21x
If the profit is less between $1000 and $1200,they 22.5%, hence:
if 1000 < x < 1200, c(x) = 0.225x
If the profit is greater than $1200,they 23.5%, hence:
if x > 1200, c(x) = 0.235x
Therefore the commission represented as a piecewise function is:
[tex]c(x)=\left \{ {{0.21x\ \ x<1000} \atop {0.225x\ \ 1200<x<1000}} \atop {0.235x\ \ x>1200} \right.[/tex]

An experiment consists of rolling two fair dice and adding the dots on the two sides facing up. What is the probability that the sun of the dots is 7 or 11
Answers
Answer:
4 /9
Step-by-step explanation:
Given that :
Number of faces on a number cube = 6
Sample space for two number faces = 6² = 36
Probability that sum of a roll is 7 or 11:
Probability = number required outcome / Total possible outcomes
Number of Required outcome = number of 7's + number of 11's
Number of 7's = 6
Number of 11's = 2
Total = 8
Total possible outcomes = 6² =36
P(sum of 7 or 11 ) = 8 /36 = 4 /9

Select the slope-intercept form of an equation for a line with y-intercept –5 and slope 2.
Answers
Answer:
y = 2x - 5

B. g(x) = a + 2
C. g(x) = 27
Answers
Answer:
g(x) = [tex]2(\sqrt[3]{x})[/tex]
Step-by-step explanation:
Parent function given in the graph attached is,
f(x) = [tex]\sqrt[3]{x}[/tex]
Function 'f' passes through a point (1, 1).
If the parent function is stretched vertically by 'k' unit,
Transformed function will be,
g(x) = k.f(x)
Therefore, the image of the parent function will be,
g(x) = [tex]k(\sqrt[3]{x})[/tex]
Since, the given function passes through (1, 2)
g(1) = [tex]k(\sqrt[3]{1})[/tex] = 2
⇒ k = 2
Therefore, image of the function 'f' will be,
g(x) = [tex]2(\sqrt[3]{x})[/tex]
