Hope you can see my workout in the picture I attached below.

f⁻¹(x) = $\frac{x - 20}{5}$

AND

f⁻¹(19) = $- \frac{1}{5}$

Answer:

Step-by-step explanation:

This is a stem and leaf plot. If you don't know what a stem and leaf plot is, try searching it before coming back and viewing the solution. I also see an "example" button. It might help to hit that too.

First, we sort the list of numbers. Here is what we get:

64, 66, 67, 68, 69, 74, 75, 76, 78, 79

Here, the stems are the tens digits and the leaves are the ones digits.

Therefore, for the stem 6, the leaves are:

4, 6, 7, 8, 9

For the stem 7, the leaves are:

4, 5, 6, 8, 9

The answer, I believe, is C

50 POINTS find the length of ab plz help me

Umnica [9.8K]

Answer:

about 9.4 units

Step-by-step explanation:

Distance formula:

√(x1 - x2)² + (y2 - y1)²

Coordinates:

A (4, 2)

B (9, 10)

Let's make 9 = x1

Let's make 4 = x2

Let's make 10 = y1

Let's make 2 = y2

Substitute into the distance formula:

√(x1 - x2)² + (y2 - y1)²

√(9 - 4)² + (2 - 10)²

Solve:

√(9 - 4)² + (2 - 10)²

√(5)² + (-8)²

√25 + 64

√89

≈ 9.4

Therefore, the length of AB is approximately 9.4 units.

Answer:

A Sarah earns more money per hour $15

Step-by-step explanation:

We need to find the slope to determine the rate ( amount per hour

Sarah

m = (y2-y1)/(x2-x1)

= (50-5)/(3-0)

= 45/3

= $15 per hour

Mia

m = (y2-y1)/(x2-x1)

= (20-10)/(2-0)

= 10/2

= $5 per hour

Find the measure of the indicated angle to the nearest degree. Thanks.

Sholpan [36]

Answer:

θ ≈ 40°

Step-by-step explanation:

Since, sinθ = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

cosθ = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

tanθ = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

In the picture attached,

Measures of adjacent side and opposite side of the triangle have been given. Therefore, tangent rule will be applied in the given triangle.

tanθ = $\frac{19}{23}$

θ = $\text{tan}^{-1}(\frac{19}{23})$

θ = 39.56

θ ≈ 40°
