Answer:

8, I believe?

Step-by-step explanation:

This is very hard with the expression not being in the correct form, but if i'm right, I believe you are saying: 3·(-8 + -4²-6) + 2. first, we have the -4², which is 16. Keep in mind i'm using PEMDAS for this equation. Then, instead of doing -8 + 16 and then (-8 +16) -6, we can combine the like terms (-8 and -6) and get -14. 16 - 14 is 2, and now we are out of the parentheses. 3*2 is 6, and 6+2 is 8. This means that your answer would be 8.

However, is you meant $(-4)^2$ , then -16 -14, or -(16+14), is -30.

-30*2 is -60, and -60 + 2 is 58.

That means that your answer is either 58 or 8, depending on the format of the equation.

Answer:

The answer is " $\bold{\frac{22}{171}}$ "

Step-by-step explanation:

There are 22 million males that have completed four years of undergraduate, according to the data below: (or more). This is predicated on a population of 171 million.

The chances we're searching about $\frac{(22\ million)}{(171\ million)} = \frac{22}{171}$

however

This proportion could be further reduced because 22 and 171 have no common features (other than 1).

Use special right triangles to find the exact value (no decimals).

fgiga [73]

Let’s find some exact values using some well-known triangles. Then we’ll use these exact values to answer the above challenges.

sin 45°: You may recall that an isosceles right triangle with sides of 1 and with hypotenuse of square root of 2 will give you the sine of 45 degrees as half the square root of 2.

sin 30° and sin 60°: An equilateral triangle has all angles measuring 60 degrees and all three sides are equal. For convenience, we choose each side to be length 2. When you bisect an angle, you get 30 degrees and the side opposite is 1/2 of 2, which gives you 1. Using that right triangle, you get exact answers for sine of 30°, and sin 60° which are 1/2 and the square root of 3 over 2 respectively.

Now using the formula for the sine of the sum of 2 angles,

sin(A + B) = sin A cos B + cos A sin B,

we can find the sine of (45° + 30°) to give sine of 75 degrees.

We now find the sine of 36°, by first finding the cos of 36°.

The cosine of 36 degrees can be calculated by using a pentagon.

that is as much as i know about that.
