Answer:
57
Step-by-step explanation:
50 + 7 =57
51+1+1+1+1+1+1+1 = 57
If you don't know the derivative of the inverse of sine, you can use implicit differentiation. Apply sine to both sides:

(true for <em>y</em> between -π/2 and π/2)
Now take the derivative of both sides and solve for it:

Answer:
D) 560 ways
Step-by-step explanation:
Use the combinations formula: nCr = n! / (r! * (n-r)!)
16 choose 3 = 16! / (3! * 13!)
take out 13! in the numerator and denominator:
(16 * 15 * 14) / 6 = 560

Answer:
18
Step-by-step explanation:
a + 7b + 4c = 2,
Multiply this equation by 9
9( a + 7b + 4c) = 2*9
9a + 63b +36c = 18
Rearrange the order
36c +9a +63b = 18
