Given the graph below, which of the following points would be included in the graph of the inverse of the function?

Svetlanka [38]

Answer : (1,-1)

a line through the points (-1, 1), (0, 2), (1, 3)

To find the point in the graph of inverse function we interchange x and y values

For point (-1 , 1) , the point on inverse function is (1, -1)

For point (0 , 2) , the point on inverse function is (2, 0)

For point (1 , 3) , the point on inverse function is (3, 1)

so (1,-1) will be included in the graph of the inverse of the function

The equation tan(55) = 15/b can be used to find the length of line AC.what is the length of line AC round to the nearest 10th 3.

Nadusha1986 [10]

Answer:

10.5 in

Step-by-step explanation:

Given

$tan(55) = \frac{15}{b}$

Required

Find length AC

The question is not detailed enough; so, I'll assume that b represents line AC.

Having said that;

We start by multiplying both sides by b

$tan(55) = \frac{15}{b}$

$b * tan(55) = \frac{15}{b} * b$

$b * tan(55) =15$

Divide both sides by tan(55)

$\frac{b * tan(55)}{tan(55)} = \frac{15}{tan(55)}$

$b = \frac{15}{tan(55)}$

Find tan(55)

$b = \frac{15}{1.42814800674}$

$b = 10.5031130731$

$b = 10.5$ (Approximated)

Length AC is 10.5

3 people work full time together on a project, but their total time on the project is to be equivalent to only 1 person working

NikAS [45]

Let x = the amount of time that the third person needs to work on the job to add up to one

1 = 1/2 + 1/3 + x

1 - 1/2 - 1/3 = x

To subtract the fractions we need to put them all over a common denominator. Let's use 3*2 = 6 as the denominator; so 1 = 6/6, 1/2 = 3/6, 1/3 = 2/6:

6/6 - 3/6 - 2/6 = x

1/6 = x

The third person must work 1/6 time on the project.

What is the circumference of the circle? Assume pi = 3.14

mezya [45]

Answer:

5 x 2 x 3.14 = 31.4

Formula of circumference:

radius(half of your diameter or given radius) x pi(3.14 or 22/7 depending on what they tell you to use for pi) x 2(just always there when finding circumference)
