Answer:
0.84 square in
Step-by-step explanation:
Since the capacity of the cable is proportional to its cross-sectional area. If a cable that is 0.3 sq in can hold 2500 lb then per square inch it can hold
2500 / 0.3 = 8333.33 lb/in
To old 7000 lb it the cross-sectional area would need to be
7000 / 8333.33 = 0.84 square in
Synthetic division:
3 | 3 11 2 -7 61
. | 9 60 186 537
- - - - - - - - - - - - - - - - - - - -
. | 3 20 62 179 598
which translates to
i.e. you're left with a remainder of 598.
The slope of the line that passes through the points (3,-4) and (7, 4) is 7/11.
