Answer:
C) 60 mph.
Step-by-step explanation:
If Ebony covers 180 miles in 3 hours as seen in the point (3, 180)
Distance=180 miles; Time = 3 Hours
Driving Rate=Distance/Time = 180/3 = 60mph
9.75-3.50=2.50x
6.25=2.50x
6.25÷2.5=2.50x÷2.5
2.5=x
Answer:
x = -1.8
Step-by-step explanation:
10(-1.8) - 2 = -18 - 2 = -20
so X = -1.8
Answer:
Try sketching an image of the rectangle. Area = length x width. To find the perimeter you would add up the length of all four sides.
Step-by-step explanation:
Answer:
Step-by-step explanation:∠ MON= -45°→→ angle lies in fourth quadrant.
Where, MN represents the path of rock, which is a straight line.
Taking the Horizontal and vertical component of OM,to get the coordinate of point M
The coordinate of point M will be [1.25 cos (-45°), 1.25 sin(-45°)]=
Taking O as center and Coordinates of O as (0,0) and Coordinates of M as () we get the equation of line OM as
y= tan (315°)× x
As general form of equation of line passing through the origin will be,
y= m x, where m is angle made by line with positive direction of x axis.
m= (360-45)°= 315°
→→y=-x
→→ y + x=0
equation of line perpendicular to OM will be
→→ x - y + k=0
Since it passes through .
→→
So, equation of initial path of stone will be:
