Slope = (y2-y1)/(x2-x1)
slope = (-2-6)/(5-3)
slope = -8/2
slope = -4
Midpoint = (8-5),(-3-9) / 2
= (3,-12)/2
= (3/2,-6)
Answer:
X=10
Step-by-step explanation:
The arc is twice the angle, so 130.
12x+10=130
12x=130-10
12x=120
x=10
Answer:
Correct answer: V₁ boat = 16 km/h and V₂ current = 4 km/h
Step-by-step explanation:
If we take speed (velocity) of the boat as V₁ and speed of the current V₂
Let us form equations:
Traveling down the current V₁ + V₂ = 60/3 = 20 km/h
Traveling against the current V₁ - V₂ = 60/5 = 12 km/h
V₁ - V₂ = 12
V₁ + V₂ = 20
If we add up the left and right sides of the equations we get:
2 V₁ = 32 => V₁ = 32/2 = 16 km/h
from the second equation we get:
V₂ = 20 - V₁ = 20 - 16 = 4 km/h
V₂ = 4 km/h
