Answers

Answer 1

Answer:

D. 12x³ + 32x - 8

General Formulas and Concepts:

Pre-Algebra

Distributive Property

Algebra I

Function NotationComposite Functions

Step-by-step explanation:

Step 1: Define

f(x) = 3x³ + 8x - 2

k(x) = 4x

k(f(x)) is x = f(x)

Step 2: Find k(f(x))

Substitute:                     k(f(x)) = 4(3x³ + 8x - 2)Distribute 4:                   k(f(x)) = 12x³ + 32x - 8

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

The function g(x) is a transformation of the cube root parent function,

A. g(x) = 1 va
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]

the sale? Fill in the blanks below,
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]

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.
