A) use definition 2 to find an expression for the area under the curve y=x^3 from 0 to 1 as a limit.
(b) the following formula for the sum of the cubes of the first n integers is proved in appendix e. useit to evaluate the limit in part (a).
1^3 + 2^3 +3^3+ = [n(n+1)/2]^2

Eric has challenged himself to walk 24,000 steps in 4 days. if eric walks the same number of steps each day, which function represents the number of steps eric still needs to walk to reach his goal with respect to the number of days since he started his challenge? a. y = 8,000x − 24,000 b. y = -8,000x + 24,000 c. y = 6,000x − 24,000 d. y = -6,000x + 24,000
