Answer:
See below.
Step-by-step explanation:
It is the one at the top left side.
The line y = x passes through the origin at an angle of 45 degrees to the x axis and rises to the right.
So if you imagine its a mirror you'll see that its a reflection in that mirror.
Answer:
f(16)= -8
Step-by-step explanation:
f(16)= 1/3(4-16)2
Answer:
Decay
Step-by-step explanation:
Considering the model:

0.85=1-0.15
Therefore, the model can be rewritten as:

This shows that the model decays by a common ratio of 0.15 or 15%.
In general, when the common ratio is less than 1, the model decays while whenever it is greater than one, there is exponential growth.
Answer:
we conclude that:

Step-by-step explanation:
Given
We have to determine 
so

Thus we conclude that:

Answer:
The measure of angle ABC is

Step-by-step explanation:
As illustrated in the diagram,we can conclude that m<ABC+m<CBD=m<ABD
This implies that





Dividing through by 10, we obtain

This implies
m<ABC=4x+27



Therefore the measure of angle ABC is
