Answer:

a. answer choice c

b. 20301

Step-by-step explanation:

You first need to understand a formula for finding the sum of consecutive integers starting from one: (m*(m+1))/2, m is the biggest number in the set.

a. The biggest number in your set is 100, so we plug in 100 for m and solve:

100*101/2=50*101=5050

b. Same thing. Use the formula t plug in 201 for m:

201*202/2=201*101=20301

The only reason you have the picture next to your question is to prove the formula (m*(m+1))/2.

A ball's position, in meters, as it travels every second is represented by the position function s(t) = 4.9t2+ 350. Include unit
loris [4]

We are given the distance as a function of time:

s = 4.9 t^2 + 350

 

To get the velocity, we take the first derivative and substitute the value of t = 2:

ds = 9.8 t dt

ds / dt = 9.8 t

velocity = 9.8 (2)

<span>velocity = 19.6 m/s</span>
