Answer:

1/x = 1/4 + 1/3

Step-by-step explanation:

In 4 hours Bethany did the whole fraction 1 of the house.

In 1 hour he would do 1/4 of it.

In 3 hours Colin did the whole fraction 1 of the house.

In 1 hour he would do 1/3 of it.

In 1 hour they would both do (1/4 + 1/3)

If it takes both of them x hours to finish 1 whole fraction of the house.

In 1 hour they will both do 1/x

That means that:

1/x = 1/4 + 1/3

That is the equation. x can be solved for.

Question 6 (5 points)
AnnyKZ [126]

The amplitude of the function is 3/2 after comparing with the general equation option (C) is correct.

<h3>What is cos function?</h3>

It is defined as the function which is in the form of cosine waves in nature, and it has a domain of all real numbers and lies between the [a, a] where is a amplitude of the function.

We have a cos function:

y = 3/2 cos(3x) + 1

We know,

f(x) = acos(bx - c) + d

The above function represents the cos function where:

a = amplitude

b = is the period of the function

c = phase shift

d = vertical shift

On comparing we get:

a = 3/2

Thus, the amplitude of the function is 3/2 after comparing with the general equation option (C) is correct.
