Q4, 4y²=60
y=√15 ( i am not sure)
q6, (5+y) ²=81
5+y=9
y=4
q7 (x+4) (x) =77
x²+4x-77=0
(x+11) (x-7) =0
x=-11(rej) or x=7
therefore ,length= 7+4=11cm
breadth=7cm
Y=mx+b // standard form
3x=12-2y
2y=-3x+12
y=-3/2x+12/2
y=-3/2x+6
So the answer is: y = -3/2x+6
The work done has the formula
W = F d
where the force and the displacement have the same direction
We can determine displacement using the distance formula
d = √[(5 - 0)² + (-1 - 4)²]
d = 5√2
Next, the force along the direction of the displacement must be determined
Use trigonometry to determine the angle θ
Finally, the work is calculated using the formula
W = F d / cos θ
substitute the values to get the answer
