Answer:
D.
Step-by-step explanation:
cos is positive and sin is negative
=>
it must be in quadrant IV.
you remember, 1 = sin² + cos²
1 = sin² + (3/5)² = sin² + 9/25
25/25 = sin² + 9/25
16/25 = sin²
sin = 4/5 or -4/5
and as sin of this angle is < 0, our solution is -4/5
Answer:
81 F
Step-by-step explanation:
Hours | Temp.
0 | 75F
1 | 77F
2 | 79F
3 | 81F
6,12,18,24,30,36,42,48,54,60,66,72,78,84,90, 96
So 6 goes into 96 16 times
96÷6=16
The 4s in 4,438 are 10 times greater than each other.
