C and D
Answer:
7 gallon
Step-by-step explanation:
Divide the space that needs paints by how much space has been painted
2500/785 = 3.18
Then double that because it takes 2 gallons to paint every 785 square feet
3.18 x 2 = 6.36
You would need 6.36 gallons of paint, which would round up to 7 because you cannot buy 0.36 of a gallon
14.6666666667
Step-by-step explanation:
2•10=20/1/3=6.66666666667+8 is that but you can write it like 14.6 with _ that on top

Answer:
- -√5
- 3/5
- -4/5
Step-by-step explanation:
The relevant relations are ...
sec = ±√(tan² +1)
cos = 1/sec
csc = 1/sin = ±1/√(1 -cos²)
Sine and Cosecant are positive in quadrants I and II. Cosine and Secant are positive in quadrants I and IV.
__
1. sec(θ) = -√((-2)² +1) = -√5
2. cos(θ) = 1/sec(θ) = 1/(5/3) = 3/5
3. csc(θ) = -1/√(1 -(-3/5)²) = -√(16/25) = -4/5
