Answer:
1.01 minutes
Step-by-step explanation:
The length of the roll is given to be 304 ft, and Bob's velocity is 5ft/s.
Velocity is defined as the rate of change of displacement over time t:

The function can be expressed to make t the subject to calculate time taken by Bob;

Hence, it takes Bob 1.01 minutes to walk the length of the roll.
The graph below shows the function.
Answer:
If your taking about a triangle, the answer = .
Step-by-step explanation:
*^2= squared*
1)The formula to calculate the missing leg of a triangle is a^2 + b^2 = c^2.
Subsituting in the formula, 8^2+17^2=c^2.
2) Simplify values, 64+289=c^2, 353=c^2
3) find the square root of the value that is left, (square root)353=18.8 (rounded to 10th place).
4) 18.8=c
Your answer would be (x,y)=(-17/14,-7)
