Answer: 3
Step-by-step explanation: if you look where the line exactly touches the graph divide the left number to the bottom number let me know if its right
C) 2/3 of a page per hour
Since he can write 1/3 of a page in 1/2 of an hour, multiply by 2 to find that he writes 2/3 of a page in 1 hour.

Yes you are right. This does involve more trig that physics. So let's review the math for a bit.
Cos(2x) = cos^2(x) - sin^2(x) Substitute 1 - sin^2(x) for cos^2(x)
Cos(2x) = 1 - sin^2(x) - sin^2(x)
cos(2x) = 1 - 2*sin^2(x) Now we need to solve for sin^2(x)
2sin^2(x) = 1 - cos(2x)
sin^2(x) = (1 - cos(2x))/2
Now all we need do is make a few substitutions.
x = ωt
Substitute (1 - cos(2ωt))/2 for sin^2(ωt)
P = (Io)^2 *R * (1 - cos(2ωt))/2
P = (Io)^2*R/2 - (Io)^2*R cos(2ωt) / 2
I think if you follow it carefully, you will find that the answer is
B <<<<< Answer.
Given:
Angle A is 4 degrees greater than the measure of Angle B. Both angles are complementary
Complementary angles have a sum of 90°
Angle A = x + 4° ; Angle B = x
x + 4° + x = 90°
2x = 90° - 4°
2x = 86°
x = 86° ÷ 2
x = 43° ANGLE B.
Angle A = x + 4° ⇒ 43° + 4 = 47°
Given:
Angle D is 5 times the measure of Angle E. These angles are supplementary. This means that their sum is 180°
Angle D = 5x ; Angle E = x
5x + x = 180°
6x = 180°
x = 180° ÷ 6
x = 30° Angle E.
Angle D = 5x = 5(30) = 150°
