Do whatever is in the parenthesis first because PEMDAS. the rule is if it’s adding and subtracting, go from left to right so you would do 7-3 first

Find (f/g) (x) and state the domain restriction. f (x) = 6x - 3 and g(x) = 12x^2 - 6x

Rufina [12.5K]

Answer:

(f/g)(x) = 1/(2x)

x ≠ 1/2

Step-by-step explanation:

$(f/g)(x)=\dfrac{f(x)}{g(x)}=\dfrac{6x-3}{12x^2-6x}=\dfrac{6x-3}{2x(6x-3)}\\\\\boxed{(f/g)(x)=\dfrac{1}{2x}}\quad x\ne\dfrac{1}{2}$

The domain restriction x ≠ 1/2 comes from the requirement to prevent the denominator factor 6x-3 from being zero.

Alina [70]

A composite number is one that can be made by multiply two numbers to each other. Since 49=7*7, 49 is a composite number.

Check:

You can check a multiplication chart, but you will see that 49 is the only one that can be multiplied by 2 numbers

A paper sheet is cut 28 inches to the nearest inches. Find the maximum and minimum length of the patient possible.

aliina [53]

Answer:

max: 28.5 inches
min: 27.5 inches

Step-by-step explanation:

If the actual dimension were different from 28 inches by more than 1/2 inch, it would be reported as a different dimension. So, the minimum that will be reported as 28 is 27.5. The maximum that will be reported as 28 will be 28.4999999.... ≈ 28.5

The maximum and minimum length of the sheet are 28.5 inches and 27.5 inches, respectively.

A group of 5 students took 15 days to finish a project. After 9 days, 3 students left the group. How many days did it take the s

sladkih [1.3K]

Using proportions, it is found that it took 15 days for the students to finish the project.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

In this problem, we have that:

100% of the project is done by 5 students in 15 days.

After the 3 students left, 2 students will have a time of x days to do 100 - (9/15) = 40% of the project.

The compound <em>rule of three</em> is given as follows:

1 project - 5 students - 15 days

0.4 project - 2 students - x days

Increasing the number of students, the number of days is reduced, hence the measures are inverse proportional and the <em>rule of three</em> is given by:

$\frac{15}{x} = \frac{2}[5} \times \frac{1}{0.4}$
