Answer:
s(5) = -12
Step-by-step explanation:
s(t) = - t³ + 7t² - 14t +8
Find the displacement during the first 5 seconds.
When t = 5
s(t) = - t³ + 7t² - 14t +8
s(5) = -5³ + 7(5)² - 14(5) + 8
= -125 + 7(25) - 70 + 8
= -125 + 175 - 70 + 8
= -12
s(5) = -12
Answer:
The domain of the relation is ![[(5,16,18,21]](https://tex.z-dn.net/?f=%5B%285%2C16%2C18%2C21%5D)
Step-by-step explanation:
we have
![[(15,65),(21,70),(18,73),(16,62)]](https://tex.z-dn.net/?f=%5B%2815%2C65%29%2C%2821%2C70%29%2C%2818%2C73%29%2C%2816%2C62%29%5D)
Remember that
The domain of the relation are the values of x
The range of the relation are the values of y
therefore
The domain is
![[(5,21,18,16]](https://tex.z-dn.net/?f=%5B%285%2C21%2C18%2C16%5D)
order them from lowest to highest -------> ![[(5,16,18,21]](https://tex.z-dn.net/?f=%5B%285%2C16%2C18%2C21%5D)
The range is
![[65,70,73,62]](https://tex.z-dn.net/?f=%5B65%2C70%2C73%2C62%5D)
order them from lowest to highest ------->![[62,65,70,73]](https://tex.z-dn.net/?f=%5B62%2C65%2C70%2C73%5D)
Answer:
22, I think
Step-by-step explanation:
You count all the squares on all of the faces.
So you count the two on the top and double it for the bottom, so four
Then, on the sides you have three so you double that and get six
Next, you double the six squares on the other side and get twelve.
Lastly, you add them up!
4 + 6 + 12
Hope this helps!
Answer:
216
Step-by-step explanation:
We know that the two angles must add up to 180
so
108+x/3=180
solve for x
72=x/3
x=216
The number of solutions of the equations can't be determined.
<h3>How to illustrate the information?</h3>
It should be noted an equation shows the relationship between the variables. It should be noted that the question is to find the number of solutions.
From the information, 3(5x + 2) = 15x
15x + 6 = 15x
Collect like terms
15x - 15x = - 6
0 = -6
Therefore, it can be see that the friend is incorrect as the number of solutions of the equations can't be determined.
