Using,
1+cot^2 x = csc^2 x
1+ (5/12)^2 = csc^2 x
1+25/144 = csc^2 x = (144+25)/144 = 169/144
csc x = sqrt (169/144) = 13/12
sin x = 1/ csc x = 1/(13/12) = 12/13 is your answer :)
Answer: 7. y = 2 sin (2x) - 3

<u>Step-by-step explanation:</u>
The general form of a sine equation is: y = A sin (Bx - C) + D where
- Amplitude = |A|
- Period (P) =

- Phase Shift =

- Vertical Shift = D (positive is up, negative is down)
7. Given:
- A = 2
- P = π =
→ B = 2 - C = 0 (none)
- D = -3
--> y = 2 sin (2x) - 3
8. Given:
- A = 1
- P =
=
→ B = 8

- D = 0 (none)

Answer:20 cookies
Step-by-step explanation:
Dividing a circular cake among people
A=pi *r^2
The radius is whole number and pi is irrational so area must be demical
And when dividing into people we should divide by a a whole number
