Answer:
Yes
Step-by-step explanation:
According to triangle inequality, the sum of any two side must be greater than the third side. So we take the two smallest side and find the sum
15 + 20 > 24
YES it can
4523 + (-4523)
4523 - 4523
0
Answer:
arithmetic
Step-by-step explanation:
An arithmetic sequence has a common difference d between consecutive terms.
22 - 16 = 6
16 - 10 = 6
10 - 4 = 6
A common difference of 6 exists between consecutive terms.
Thus the sequence is arithmetic.
Answer:
On average, cars enter the highway during the first half hour of rush hour at a rate 97 per minute.
Step-by-step explanation:
Given that, the rate R(t) at which cars enter the highway is given the formula

The average rate of car enter the highway during first half hour of rush hour is the average value of R(t) from t=0 to t=30.

![=[100(t-0.0001\frac{t^3}{3})]_0^{30}](https://tex.z-dn.net/?f=%3D%5B100%28t-0.0001%5Cfrac%7Bt%5E3%7D%7B3%7D%29%5D_0%5E%7B30%7D)
![=100[(30-0.0001\frac{30^3}{3})-(0-0.0001\frac{0^3}{3})]](https://tex.z-dn.net/?f=%3D100%5B%2830-0.0001%5Cfrac%7B30%5E3%7D%7B3%7D%29-%280-0.0001%5Cfrac%7B0%5E3%7D%7B3%7D%29%5D)
=2901
The average rate of car is 

=97
On average, cars enter the highway during the first half hour of rush hour at a rate 97 per minute.
