Answer:

Step-by-step explanation:
Use the midpoint formula:

We want to find the midpoint of the line
that has endpoints.

We simplify to get;

This finally gives:

The correct answer is A.
Answer:
401.92u^3
Step-by-step explanation:
Volume for a cylinder=(pi*r^2)*h because it is the area of the circle times the height of the cylinder so,
(3.14*4^2)*8=401.92
Answer:
4/3
Step-by-step explanation:
I am guessing that the correct form of equation
is:
f(x)
= 16,800(0.9)^x
where
x is the exponent of (0.9)
Since
we are looking for the original population and x stand sfor the number of years,
therefore x=0
substituting:
f(x) = 16,800(0.9)^0
Since (0.9)^0 would just be equal to 1. Therefore
the original population is
16,800.
Answer: B. 16,800
Sin ( theta ) = opposite / hypotenuse
sin ( 37° ) = 13 / x
