what is the inverse of the function below f(x) =x/5 -2

Answers

inverse f(x) =x/5 -2 = 5(x+2)

Answer:

[tex]y=5x+10[/tex]

Step-by-step explanation:

[tex]f(x)=\frac{x}{5} -2[/tex]

To find the inverse of the function we do the following steps

Replace f(x) with y

[tex]y=\frac{x}{5} -2[/tex]

Replace y with x and x with y

[tex]x=\frac{y}{5} -2[/tex]

Solve the equation for y

Add 2 on both sides

[tex]x+2=\frac{y}{5}[/tex]

Now multiply by 5 on both sides

[tex]5(x+2)=y[/tex]

Now distribute 5 inside the parenthesis

[tex]5x+10= y[/tex]

[tex]y=5x+10[/tex]

First, you have to do the formula:


A= 1/2(b1+ b2)×h

-----------------------------------------------------

Now plug in the numbers:

A=1/2(18+14)×12

----------------------------------------------------

Now solve:

A=1/2(18+14)×12

A=1/2(32)×12

A=16×12

When it says 7 more than a number equals 21, the "more than" is addition, a number is x (because it's the unknown number). So this one is x+7=21.

When it says 39 less than a number is 21. "Less than" means to subtract. The 39 is less than x, so it's x-39=21.

8 times a certain number increased by 1 is 65. Break it down, first 8 times a number, so it's 8*x or 8x. Then we add 1 to that, so it's 8x+1=65.

5 times some number decreased by 2 times the number is 42. Decreased by is subtraction. So it's 5x-2x=42.

When you look for the key words increased by (add), more than (add), multiplied by, times, less than (subtract), decreased by (subtract), is (equal sign), they will help determine what you need to do.

I hope this gives you a little more understanding. Good luck with it! :)

A cone - shaped building has a height of 6 meters and a base with a diameter of 10 meters. The building will be filled with road salt that costs $25 per cubic meter. How much will it cost to fill the building with road salt? Use 3.14 for π Round to the nearest hundredth HELP ME ASAP!!!!

Answers

The formula for the volume of a cone is
.. V = (1/3)*π*r^2*h
The radius (r) is half the diameter, so is 5 m. Fill in the numbers and do the arithmetic.
.. V = (1/3)*3.14*(5 m)^2*(6 m) = 157 m^3

The cost will be $25 for each of those cubic meters, so is
$25*157 = $3925.00.
Formula
V= (1/3) pi r^2 h
r = d/2 = 10/2 = 5
h = 6
pi = 3.14
V = (1/3) * 3.14 * 5^2 * 6
V = (1/3) * 471
V = 157 cubic meters.

1 cubic foot cost $25
157 cubic feet cost x Cross multiply.

x = 25 * 157
x = 3925 dollars.

Find the magnitude and direction of the vector. Round the length to the nearest tenth and the degree to the nearest unit. Diagram is not drawn to scale.

Answers

Refer to the diagram shown below.

The vector has a magnitude of a and a direction of θ degrees south of west. 

Use the Pythagorean Theorem to calculate a.
a² = (-530)² + (-200)² = 320900
a = √(320900) = 566.48 mi ≈ 566.5 mi

By definition,
tan θ = (-200)/(-530) = 0.3774
θ = tan⁻¹ 0.3774 = 20.68° ≈ 21°

Answer: about 566.5 mi; 21° south of west.

Hopes this helps u :) 

Answer:

[tex]IQR=4.75[/tex]

Step-by-step explanation:

The given data is:

12,14,16,17.5,10,18,15,15.5,19

In order to find the interquartile range, we have to arrange the given data set in ascending order, thus

10, 12, 14, 15, 15.5, 16, 17.5, 18, 19

Now, the lower quartile is: 10, 12, 14, 15

Median is given as:

[tex]M=\frac{14+16}{2}=\frac{26}{2}=13[/tex]

And the upper quartile is given as:

16, 17.5, 18, 19

Median is given as:

[tex]M=\frac{17.5+18}{2}=17.75[/tex]

thus, the Interquartile range is given as:

[tex]IQR=Upper quartile-Lower quartile[/tex]

[tex]IQR=17.75-13[/tex]

Pe ling needs 2 yard of fabric for a craft project. She has 3 feet already. How many inches of fabric does she still need ?

Answers

First, you want them to be the same units. 
We'll convert yards to feet.

Since there are 3 feet in a yard 

2 yards * 3 = 6 feet

So she needs 6 yards and has 3 feet.

6-3=3     3 feet is needed

So to make things easier convert 3 feet to inches
12 in. in a foot

12*3 feet= 36 inches
She needs 36 inches of fabric
She needs 2 yards. 

2 yards = 6 feet

3 feet = 36 inches

So, she has half of it done already.
If 2 yard = 6ft, then 1 yard = 3ft.
In 1 foot, there is 12in.

Therefore, she still needs 36 inches of fabric.
