Answer:
Distance = 17.5 miles
Step-by-step explanation:
Note.
Given question is not complete
Given:
Speed upstream = x
Time taken in upstream = 3.5 hour
Speed in return trip = (x+2)
Time taken in return trip = 2.5 hour
Computation:
Distance = speed × time
Distance = x (3.5)
Distance = 2.5 (x+2)
Distance = 2.5x + 5
So,
2.5x + 5 = 3.5 x
1.5 x = 5
x = 5 miles/hour
Distance = x (3.5)
Distance = 5 (3.5)
Distance = 17.5 miles
H = 180m
k= 1.5cm = 3.5 m
180/h=3.5/1.5
h=(1.5/3.5)180 is approximately 77.14 m or 900/7 m
Answer:
π/4
Step-by-step explanation:
The reference angle will be the minimum of the absolute value of the angle, and the difference of that absolute value and pi.
ref angle = min(|-3π/4|, π -|-3π/4|) = min(3π/4, π/4)
ref angle = π/4
Answer:
OMG you are so pretty
Step-by-step explanation:
We have 2 points , so we can find a slope
m=( y2 - y1)/(x2 - x1)
m = (-3 - 0)/ (0- (-15/2)) = -3/(15/2) = (-3 *2)/15 = -2/5
y =(-2/5)x + b
b is a y value of y-intercept point, so b= -3
y = (-2/5)x - 3
The answer is A. y = (-2/5)x - 3
