Answer:
Object point Q (x,y) ------------- image point Q'( -y,x)
Step-by-step explanation:
When a point A (x,y) is rotated 90 degrees counterclockwise about the origin the resulting image of the point is A'(-y,x)
This means first you alternate the positions of x and y coordinates then add a negative sign on the now new y coordinate.
Example a point B(2,3) rotated 90° counterclockwise about the origin will form an image B'(-3,2)
So if point Q (x,y) ------------- image Q'( -y,x)
Substitute real values for (x,y) coordinates to get correct answer.
The problem is simply asking us to convert the units from BTU to units of foot pound force. To do this, we use the conversion ratio 1 BTU/778.169 ft-lbf. We do as follows:
1500 BTU/hr ( 777.169 lbf-ft / 1 BTU ) = 1165753.5 lbf-ft/hr
Hope this answers the question.
