Answer:
The first one or the 2nd one, since it says NOT worth half, I would say the first one is the answer.
Step-by-step explanation:
So, to do this, all you need to do is add up all the values, and then, with that number, divide by how many values are given.
150+165+165= 480
480/3= 160
What is the rest of the bottom pic?
Answer:
h = 17.65 m
Step-by-step explanation:
The given equation gives the speed at impact :

h is height form where the object is dropped
Put v = 18.6 m/s in the above equation.

So, the object must be dropped from a height of 17.65 m.
Answer:

Step-by-step explanation:
<u>Composite Function
</u>
Given f(x) and h(x) real functions, the composite function named
is defined as:

It can be found by substituting h into f.
We are given the functions:


It's required to find 
As defined above:

Thus:

Find h(2):

h(2)=0
Now:
