Answer with Step-by-step explanation:
We are given that a ball is thrown into the air with velocity

Height after t seconds is given by

We have to find the average velocity for the ball during the time [1,2].
We know that average velocity=
Average velocity=v=
Substitute t=1 then we get
Average velocity=
Substitute t=2 then
Average velocity=
Average velocity[/tex]=-24 m/s[/tex]

Answer:
4033
Step-by-step explanation:
An easy way to solve this problem is to notice the numerator, 2017^4-2016^4 resembles the special product a^2 - b^2. In this case, 2017^4 is a^2 and 2016^4 is b^2. We can set up equations to solve for a and b:
a^2 = 2017^4
a = 2017^2
b^2 = 2016^4
b = 2016^2
Now, the special product a^2 - b^2 factors to (a + b)(a - b), so we can substitute that for the numerator:
<h3>

</h3>
We can notice that both the numerator and denominator contain 2017^2 + 2016^2, so we can divide by
which is just one, and will simplify the fraction to just:
2017^2 - 2016^2
This again is just the special product a^2 - b^2, but in this case a is 2017 and b is 2016. Using this we can factor it:
(2017 + 2016)(2017 - 2016)
And, without using a calculator, this is easy to simplify:
(4033)(1)

Answer:
37
Step-by-step explanation:
-3x^{2} + 1
replace (x) with (-2)
-3(-2)^{2} + 1
6^2 +1=36+1
=37
