Answer:B
Explanation:In a function only one input is used there this is not a function
The amount of interest that will be paid in the first 5 years is $120.00
Given:
The given function is:

The graph of the function is given.
To find:
The end behavior of the given function.
Solution:
We have,

From the given graph it is clear that the function approaches to -4 at x approaches negative infinite and the function approaches to negative infinite at x approaches infinite.
as 
as 
Therefore, the end behaviors of the given function are:
as 
as 
Answer:
7. 49
8. 10.4
Step-by-step explanation:
7) our hypotenuse is 8, and the side opposite the base of ladder and ground angle is 6, therefore we can use Sin
sin = opposite/hypotenuse
sin(x) = 6/8 = 3/4
sin-1(3/4) = 49
8) using the theorem that alternate exterior angles are congruent
the angle opposite side x is 30
tan = opposite/adjacent
tan(30) = x/18
x = 18tan(30) = 6√(3) = 10.4
you can also use 30-60-90 special right triangles.
the side opposite 30 is x
side opposite 60 is x√(3)
and side opposite 90 is 2x
The 11th triangular number = 66
