She walks 70 hours in total 10 20 and 40
Answer:
I think it's the third one sry if I'm wrong
Step-by-step explanation:
Since w||v
<a=140 ( Vertically opposite angles and corresponding angles)
Answer:
See explanations below
Step-by-step explanation:
Using the coordinate points in the table (0, 4) and (2, 9)
Slope m = y2-y1/x2-x1
m = 9-4/2-0
m = 5/2
slope = 5/2
Get the y-intercept
Substitute m = 5/2 and (0,4) into y = mx+c
4 = 5/2(0) + c
4 = 0+c
c = 4
y-intercept is 4
Get the equation
Recall that y = mx+c
y = 5/2x + 4
Using another 2 points (2,9) and (4, 14)
Slope = 14-9/4-2
Slope = 5/2
Since the slope is the same for the coordinates, hence the the equation is correct
Answer:
θ = 2π
Rotational period = T
so the angular velocity is:
w=2πT
v=Dt
D=vt
