Answer:
b
Step-by-step explanation:
2)
(-3, 3) (2,0)
slope = (3-0)/(-3-2) = -3/5
3)
y = 3
so slope = 0
Answer:
We have sinθ = 12/13
The method here is to figure out the value of θ
Using a calculator sin^(-1)(12/13) =67.38°
67.38° is in quadrant 1 so we must substract 67.38° from 180° wich is π
- 180-67.38= 112.61° ⇒ θ= 112.61°
Now time to calculate cos2θ and cosθ using a calculator
- cosθ = -5/13
- cos2θ = -0.7
The values we got make sense since θ is in quadrant 2 and 2θ in quadrant 3
Answer:
4
Step-by-step explanation:
13497/1250
12500 + 997/1250
12500 + 0.7976
12500.7976
