I do want to help.

I already told you the situation in the message center

I would recommend for you to search them up on the web.

Really sorry!

and:  P(A) and P(B)  =  P(A) x P(B)

or:     P(A) or P(B)  =  P(A) + P(B) - [ P(A) and P(B) ]

I'll attempt this problem in a different way ...

Draw right triangle(ABC) with C the right angle.

Let AC = 8 and BC = 15.

Using the Pythagorean Theorem AB = 17.

Drop a perpendicular from angle(C) to the hypotenuse AB. 

Label the point of intersection P.

PC is the height.

By similar triangles (or a theorem from your textbook):

PA / AC  =  AC / AB    --->     PA / 8  =  8 / 17        --->     PA  =  64 / 17

PB / BC  =  BC / BA    --->     PB /15  =  15 / 17     --->     PB =  225 / 17

Continuing with similar trianges (or another theorem):

AP / PC  =  PC / PB     --->     ( 64 / 17 ) / PC  =  PC / ( 225 / 17 )

   cross-multiplying:     ( 64 / 17 ) · ( 225 / 17 )  =  PC² 

                                    ( 64 · 225 ) / ( 17 · 17 )  =  PC² 

                                                    14,400 / 289  =  PC² 

                                                           120 / 17  =  PC

   as a decimal:  7.0588...

Geno's answser

I just answered this on a different thread. It is really annoying and rude when people repost with no link.

Here is my answer

I'd do it like this

2+3a=3+2b

3a-2b=1

One solution is a=1 and b=1  (these are not real solutions yet but they work for this equation.

3(1)-2(1)=1

3(1+2t)-2(1+3t)=1        here I have added 6t and then taken it away again.

Now you can answer it.

Hello! I'm working on the problem now. There's quite a bit of steps. However, it is possible. Don't get discouraged. First you need to determine the length of the hypotenuse using the Pythagorean theorem. It's length is 17. 

From there, I looked up how to do altitude and you need the height of the triangle so I decided to use this formula: 
a = 1/2 * bh

Before using this formula, you need to calculate the area first. For this, I used Heron's Formula. You need to find the semi perimeter, so to get this, add all of the sides together & divide by 2. You should get 20. Then I got the area by using Heron's Formula:

\(\sqrt{20(20-17)(20-15)(20-8)} = \sqrt{20(3)(5)(12)} = \sqrt{3600} = 60\)
 

Now that you have your area, 60, you can use the formula above, a = 1/2 * bh. Just substitute your area into the equation and solve for you height.

\(60 = \frac{1}{2}(14)h\)

\(60 = 7h\)

\(h = 8.57\)

(Will continue... still solving)

9x² + 7x  =  0

x(9x + 7)  =  0

Either  x = 0     or     9x + 7  =  0

                                       9x  =  -7

                                         x  =  -7/9

These two values for x are the solution.

32₅  =  17

23₇  =  17

5 + 7  =  12

Does anyone have a better answer?

Slope = rise / run     given for this problem as   -2 /1 = -2

y = mx + b      m = slope   

   so we have    y = -2x+b     Now substitute in the point given to calc 'b'

                         2 = -2(-2) + b

                                   so b = -2

 y = -2x-2   

There are  (  1+5 +10+6+37) = 59 JOBS     Median is the one in the middle..... 29 above    29 below

                   there is 37 Admin Spec jobs  of which on is # 30  (29 above   29 below)   Median Value = 23 000

answered.

Get cos(theta) in terms of x

Get sin(theta) in terms of y

then my hint is     sin^2(theta)+cos(^2(theta)=1

It is an isosceles triangle so the equal sides must be 10 or 4.

10 + 10 + 4 = 24.

20 > 4.

4 + 4 + 10 = 18.

8 is not > 10 thus it is not a triangle.

The perimeter is 24.

If you don't understand anything feel free to ask!

He/She forgot to mention that these questions are for a BillNye video(told me in message center).

Usually we don't do anything other than math but science is sometimes ok especially when it's physics, since physics is the most scientific science.

If you know what I mean.

In the future it should be noted that if your question comes with other content it should not be excluded as "What evidence do you see" and "Was there evidence" point towards a source withheld. 

Also even if you didn't make it it's ok to say it's homework as... 99.9% of the questions here are homework.

Hello! Welcome to the site. I've been here for over half a year. I just want to let you know, this is mainly a site for math and sometimes science as well, because sometimes there is math in science
However, there is a site you can use to get help for questions like this. You can ask all different types of questions, regarding pretty much anything. It's called Brainly. :) 

We're happy to have you, and we hope that we can help you with any problems you may have!

sumfor(n, 1, 20, (5*n - 2)^2) = 67,630

Let's get the inverse of                                                             y  =  x² - 6x + 12

Interchange x and y:                                                                 x  =  y² - 6y + 12

                                                                                           x - 12  =  y² - 6y

Complete the square:                                                   x - 12 + 9  =  y² - 6y + 9

                                                                                             x - 3  =  (y - 3)²

Take the square root (choose the negative):              - sqrt(x - 3)  =  y - 3

Finish:                                                                   - sqrt(x - 3) + 3  =  y

Create k(x) to be the inverse:     k(x)  =  - sqrt(x - 3) + 3

Now, if you choose a value for x            (say, 2),

                                                 find f(2)  (it's 4) 

                                  and then find f(4)  (it's back to your original number, 2)

Nevermind, I got it. But thanks. :)

33336 , 33363 , 33633 , 36333 , 36666 , 63333 , 63666 , 66366 , 66636 , 66663 , Total =  10 such numbers

Doing the math, I did cscθ = 3.16/3 and I got 71.56 degrees.

Now the only part I'm confused about is what it means by simplest form lol

Okay, so I did it both ways and I think based off of my knowledge, it is more logical for it to be the angle near the orgin, because if it was the other one, it would be 17 degrees, which is obviously not the answer, because that would make the third angle obtuse, and it isn't.
