Answer:
I've seen this question before :)
Step-by-step explanation:
Divide $0.90 by 2 to get the cost per part. You get $0.45.
To get the cost of 11 parts, multiply $0.45 by $11.
The answer is $4.95.

Answer:
a. 6, b. 99, c. 63
Step-by-step explanation:
A) The function s(t) is in the vertex form. The standard vertex form is a(x-h)+k where the vertex is (h,k). The vertex is the highest (or lowest in some cases) point of the graph, so if we use s(t) to get the vertex we get that h=6 and k=99. This means that for a student to get a perfect score they need to study 6 hours
B) We can just take the k value from the first question because that's the highest value for s(t), so the highest score will be 99
C) For this one just plug in 0 for time, so -(0-6)^2+99. This equals -(-6)^2+99, which equals 99-36 =63
So what you do is multiply 60, 30, and 100 together to get 180,000. Then divide 180,000 by 18,000 (simplify it to 180 ÷ 18) and the answer is 10. So they could turn it up 10 notches.
Answer:
If you rotate an angle 360 degrees around, your final angle will be facing the same direction
Thus, the coterminal angle is
