15. The terminal side of 
intercepted the unit circle at:
(0,-1).
This implies that:
This implies that:
16) We have that: 
.
We illustrate this on the right triangle and apply the Pythagoras Theorem as follows:
Using the mnemonics SOH-CAH-TOAH, we have:
17. We want to verify that: 
Verifying from the LHS
Recall that from the Pythagorean identity:
18. We have:
When 
, we have
When 
, 
We can see this is not defined for all real values of x.
M=6 is the correct answer

9 is 82 blue v-necks and 43 red crew necks. 10 is for one angle it's 56 and fornthe other it is 34. For the first one, let a = blue v-necks and b = red crew necks. Then we have a system of equations: a + b = 125(total amount of shirts) and 7.95a + 8.95b = 1036.75(cost of shirts times how many shirts sold is the profit they got). Multiplyig the top equation by 8.95 we get 8.95a + 8.95b = 1118.75. Subtract that from the second and we get (8.95 - 7.95)a + (8.95 - 8.95)b = 82. The b is gone from that zero and a is being multiplied by one so that means a = 82. Plugging that into a + b = 125 and we get 82 + b = 125 ∴ b = 43. For the second question, since two angles are complementary, we can say ∠A = 90° - ∠B Then its says ∠A = 2∠B - 12. So putting the second ∠A def. into the first equation we get 2∠B - 12 = 90° - ∠B. Adding ∠B to both sides we get 3∠B -12 = 90°. Then adding 12 to both sides we get 3∠B = 102°. Divide by three and you get ∠B = 34 ∴ ∠A = 56.
Answer:
Step-by-step explanation:
You can't see the diagram for 27. We do not know what the entire question consists of.

This is a calculator question. Your calcualator has a ^ or y^x or x^y key.
To solve this problem, use one of these keys.
225 y^x 0.5 = 15 There are two answers: - 15 and 15. The question only wants 15.
If you repost 27, I'll come back and do it.
Divide both sides of the equation by 3 to get p by its self.
