Answer:

\frac{1}{12y}

Step-by-step explanation:

This is a multiplication problem.

We want to multiply \frac{9z^3}{16xy}\cdot \frac{4x}{27z^3}

We factor to get:

\frac{9z^3}{4\times 4xy}\cdot \frac{4x}{9\times 3z^3}

We now cancel out the common factors to get:

\frac{1}{4\times y}\cdot \frac{1}{1\times 3}

We now multiply the numerators and the denominators separately to get.

This simplifies to \frac{1}{12y}

Therefore the simplified expression is \frac{1}{12y}

A photo booth’s profit as a function of users is represented in the table. The function is quadratic.
Luda [366]

Answer:

The vertex represent the minimum amount of profit

Step-by-step explanation:

Plot the function to better understand the problem

Let

x ----> the number of users in thousands

y ---> the Monthly profit in thousands

using a graphing tool

see the attached figure

we have a vertical parabola open upward

The vertex represent a minimum

In the context of this problem

The vertex represent the minimum amount of profit

In this problem the vertex is the point (0.4,-4)

0.4 represent -----> 0.4(1,000)=400 users

-4=-4(1,000)=-$4,000 (profit negative)

Rita is starting a running program. the table shows the total number of miles she runs in different weeks. what is the equation
Stolb23 [73]

Based on the table, the equation of the line of best fit to the nearest thousandths is equal to y = 1.671x + 4.699.

<h3>How to determine the equation of the line of best fit?</h3>

Mathematically, the equation of the line of best fit is calculated by using this formula:

y = mx + c

<u>Where:</u>

  • m is the slope.
  • c is the intercept.

Based on the table, the slope and intercept to the nearest thousandths are equal to 1.671 and 4.699 respectively.

Therefore, the equation of the line of best fit is equal to y = 1.671x + 4.699.

Answer:

  • D. f(q) = 2q + 3

Step-by-step explanation:

<u>Given equation:</u>

  • 6q = 3s - 9

<u>q is independent variable, we need to solve it for s:</u>

  • 6q = 3s - 9
  • 3s = 6q + 9
  • s = 2q + 3

<u>Correct choice is </u>

  • D. f(q) = 2q + 3
