A wire 31ft long is stretched from the top of a flagpole to the ground at a point of a flagpole to the ground at a point 15ft fr

Answer:the height of the flagpole is 27.12 ft

Step-by-step explanation:

The wire makes an angle with the ground and forms a right angle triangle with the flag pole. The length of the wire represents the hypotenuse of the right angle triangle. The height of the flag pole and the ground distance from the wire represents the adjacent and opposite sides respectively.

To determine the height of the flagpole, x we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

31² = x² + 15²

x² = 961 - 225 = 736

x = √736. = 27.12 ft

How to graph this! Thank you
matrenka [14]

Answer:

Step-by-step explanation:

Yay graphs!!!!!!

Okay so as you should know, the structure of a linear equation is y = mx + b.

B is the y-intercept

so the first thing to do is mark the coordinates (0,1) as the y-intercept

Now the slope is 1/4 x

this is also known as rise/run

A simpler way to do that is from (0,1) move up 1 and over four and place a point there

The coordinate should be (4,1)

Then draw a line through the two points

Suppose that replacement times for washing machines are normally distributed with a mean of 9.3 years and a standard deviation o
Harlamova29_29 [7]

Answer:

The probability is 0.0643

Step-by-step explanation:

* Lets revise some definition to solve the problem

- The standard deviation of the distribution of sample means is called σM

- σM = σ/√n , where σ is the standard deviation and n is the sample size

- z-score = (M - μ)/σM, where M is the mean of the sample , μ is the mean

 of the population  

* Lets solve the problem

- The mean of the washing machine is 9.3 years

∴ μ = 9.3

- The standard deviation is 1.1 years

∴ σ = 1.1

- There are 70 washing machines randomly selected

∴ n = 70

- The mean replacement time less than 9.1 years

∴ M = 9.1

- Lets calculate z-score

∵ σM = σ/√n

∴ σM = 1.1/√70 = 0.1315

∵ z-score = (M - μ)/σM

∴ z-score = (9.1 - 9.3)/0.1315 = - 1.5209

- Use the normal distribution table of z to find P(z < -1.5209)

∴ P(z < -1.5209) = 0.06426

∵ P(M < 9.1) = P(z < -1.5209)

∴ P(M < 9.1) = 0.0643

* The probability is 0.0643

What is the inverse of the function f(x) = 2x + 1?
Liula [17]

<em><u>Inverse</u></em><em><u> </u></em><em><u>Of</u></em><em><u> </u></em><em><u>Functions</u></em>

I use a certain way to find the inverse of a function.

Replace H(x) with y.

y=2x+1

Replace y and x.

x=2y+1

Find y.

x-1=2y

Divide both sides by two.

x-1/2=y

<em>The</em><em> </em><em>Answer</em><em> </em><em>Is</em>

<em>h^{ - 1} (x) =  \frac{x - 1}{2}</em>
