Solve for the missing side: simplify the radical ​

Mathematics
1 answer:
Viefleur [7K]2 years ago
5 0

Answer:

x=8\sqrt{5}

Step-by-step explanation:

I will assume the following:

  • You know how to use  the quadratic formula
  • You know how to simplify radicals
  • You know how to use the pythagorean theorem.

The challenge of this exercise comes from using the pythagorean theorem and setting up a few equations.

Given that we have a segment 36 units long and another segment that is 16, it is trivial to get the other segment, 20. Additionally, there are two sides that I want to name so that way I can make a couple of substitutions. I will call these side a and side b. (see attachment 1)

Now comes with setting up three equations. I will start with the two smaller triangles, using side a and side b. See attachments 2 and 3.

Now with the big triangle. I will set up one last equation. See attachment 4.

Given what we know about attachment 2 and 3, we can make two substitutions. See attachment 5. I assume you know how to do the rest and arrive at your only real solution.

Given f(x)<br> 6x – 5<br> a) Evaluate f(5)<br> f(5)<br> b) Evaluate f( - 3)<br> f(-3) =
prisoha [69]
We have the equation f(x)=6x-5 to start with
Now in order to answer the question we have to know that f(5) is the same thing as setting x=5 and solving for f(5)

(A) f(5) = 6(5) - 5 = 30 - 5 = 25
(B) f(-3) = 6(-3) - 5 = (-18) - 5 = -23

So f(5) = 25 and f(-3) = -23

7x10^6 is _________ x the value of 2x10^4
sashaice [31]

Answer:

350

Step-by-step explanation:

so the first step is to find the values of each of them

7x10^6=7000000

2x10^4=20000

then we divide 7000000 by 20000

7000000/20000=350

so the answer is 350

hope this helps :)
