Answer: A>7
Step-by-step explanation:
Answer:
Step-by-step explanation:
x²+y² = 5²
3²+y² = 25
y² = 16
y = ±√16 = ±4
Since the terminal side is in quadrant IV, y = -4
sinθ = -4/5
Answer:
5
Step-by-step explanation:
Put -2 where x is and do the arithmetic.
f(x) = 2x² -3
f(-2) = 2(-2)² -3 = 2(-2)(-2) -3 = 8 -3
f(-2) = 5
Answer:
8√3.
Step-by-step explanation:
192 = 2 * 2 * 2 * 2 * 2 * 2 * 3
The square root of the multiple of the 6 2's is 2*2*2 = 8
so √192 = 8√3.
