Answer:
(C)
Step-by-step explanation:
Plug in 1 for s, and 2 for t:
5t - 2 = 5(2) - 2 = 10 - 2 = 8
t + 6 = (2) + 6 = 8
2s + 3 = 2(1) + 3 = 2 + 3 = 5
3s + 2 = 3(1) + 2 = 3 + 2 = 5
NM = PO = 8 ; NO = MP = 5 ∴ (C) is your answer

Answer:
10
β
Step-by-step explanation:
We can find this two ways, first by seeing in the step after it, cosines are canceled out. Since you already have 10β on the next step, you can assume that (since only the cosines changed and the cosine next ot the blank was removed), the value is 10β.
You can also use double angle formulas from the previous step:
(sin(2β) = 2 sin(β) cos(β))and find that:
5 sin (2β) sin(β) = 5 * (2 sin(β) cos(β)) sin(β)) = (10 sin(β) sin(β)) cos(β) =
10β cos(β)
But since cos(β) is already present, we can see that the answer is 10β
Answer:
If I'm thinking right then the answer should be 5% ?
There's 8 students total if I'm correct?
2 people got 15.
2 people got 16.
1 person got 17.
2+2+1=5
2 person got 14.
1 person got 12.
2+1=3 There's 8 students total. but the answer should be 5%.
