Step-by-step explanation:
1) As U is the mid point of TV ,it divides the whole line in two equal parts:
TV=TU+UV
TU=UV
Subtitute values:
5x+6=23+23
5x+6=46
5x=46-6
5x=40
x=40/5
x=8
2) Q is mid point of PR so PQ=QR
PR=PQ+QR
15x-29=6x-1+6x-1
15x-29=12x-2
15x-12x=29-2
3x=27
x=27/3
x=9

Answer:Non, Non, Linear, Linear
Step-by-step explanation:
An exponential model can be described by the function
![f(x) = a(b)^x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20a%28b%29%5Ex)
where: a is the initial population or the starting number, b is the base and x is the number of periods elapsed.
When the base of an exponential model is greater than 1 it is called a growth factor, but when it is less than 1 it is called a decay factor.
Given the exponential model
![n=20.5(0.6394)^t](https://tex.z-dn.net/?f=n%3D20.5%280.6394%29%5Et)
n is the final output of the exponential model, 20.5 is the starting number, 0.6394 is the base and t is the number of periods/time elapsed.
Here, the base is 0.6394 which is less than 1, hence a decay factor.
Therefore, <span>the
base, b, of the exponential model is 0.6394; It is a
decay factor.</span>
Answer:
x=1
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
