(1 point) Consider the function f(x)=x23+8. In this problem you will calculate ∫30(x23+8)dx by using the definition ∫baf(x)dx=limn→[infinity][∑i=1nf(xi )Δx] The summation inside the brackets is Rn which is the Riemann sum where the sample points are chosen to be the right-hand endpoints of each sub-interval. Calculate Rn for f(x)=x23+8 on the interval [0,3] and write your answer as a function of n without any summation signs. You will need the summation formulas on page 364 of your textbook. Rn= (((2n^2)+3n+1)/(6n^2))+24 limn→[infinity]Rn= Note: You can earn partial credit on this problem.

step-by-step explanation:

i think because what else can be a sample of every member

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
