Let the number of boxes = x
<u>moving company:</u>
Total cost = 150 + 5x
<u>taxi service:</u>
Total cost = 20x
<u>For the moving company to be cheaper:</u>
150 + 5x < 20x
150 < 20x - 5x
150 < 15x
10 < x
x > 10
Answer: Moving company is cheaper when there is more than 10 boxes.

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
What? I can’t understand. What do you need help on!
