Answer:
Step-by-step explanation:
The formula for the length of a vector/line in your case.
Answer:
v = 96 km/h
Step-by-step explanation:
Data:
d = 240 km
t = 2.5 h
speed = d/t
speed = 240/2.5 = 96 km/h
To find the circumference calculate pi x the diameter of the circle.
Since the radius is 14, the diameter is 28. 3.14 x 28 = about 87.96
Answer: y=2x+4 for parallel and y=-1/2x+1 1/2
Step-by-step explanation: you need to do an equation using the slope which you can find by using y2-y1/x2-x1
from there you have to use y-y1=m(x-x1)
Answer:
y = -9 + 75 = 66
x = 27-(-11) = 27 + 11 = 38
slope = 66/28
