Answer:
10 N
Explanation:
Work done is the dot product of the force magnitude with distance and cosine of the angle betweenthem.
Equation to use: W=|F|*|d|*cosθ
Your unknown is the force F; You have one equation, oneunknown.
40j=(F)*(4m)*cos(0)
F=40j/4m
F=10N
Answer: (x - 4)² + (y - 7)² = 9
<u>Explanation:</u>
The equation of a circle is: (x - h)² + (y - k)² = r² where
- (h, k) is the center
- r is the radius
Given: (h, k) = (4, 7)
Find the intersection of the given equation and the perpendicular passing through (4, 7).
3x - 4y = -1
-4y = -3x - 1

--> 

Use substitution to find the point of intersection:
Use the distance formula to find the distance from (4, 7) to (5.8, 4.6) = radius

Input h = 4, k = 7, and r = 3 into the circle equation:
(x - 4)² + (y - 7)² = 3²
(x - 4)² + (y - 7)² = 9
