Given:
The population, P, of six towns with time t in years are given by the following exponential equations:
(i) 
(ii) 
(iii) 
(iv) 
(v) 
(vi) 
To find:
The town whose population is decreasing the fastest.
Solution:
The general form of an exponential function is:
Where, a is the initial value, b is the growth or decay factor.
If b>1, then the function is increasing and if 0<b<1, then the function is decreasing.
The values of b for six towns are 1.08, 1.12, 0.9, 1.185, 0.78, 0.99 respectively. The minimum value of b is 0.78, so the population of (v) town is decreasing the fastest.
Therefore, the correct option is b.
An inverse function produces points (y,x) for every point (x,y) produced by the parent function. So to find the inverse function, you solve for the independent variable and when done switch the variable labels....
y=x+5 subtract 5 from both sides
y-5=x now switch labels
y=x-5
So if f(x)=x+5
f^-1(x)=x-5
Answer:
One witch is straight across
Step-by-step explanation:
The image of the regular hexagon coincides with the pre-image 6 times during rotation.
A regular hexagon is a polygon that has six equal sides and six equal angles.
In a single rotation which is usually the rotation of an object at 360°, the number of times in which the regular hexagon coincides with its pre-image is 6 times, this is because it has 6 equal sides and 6 equal angles.

Answer:
B/ x=4
Step-by-step explanation:
Just take 2x to another side to be neg-, the same thing with 4 , then divide it both sides by 4 to get the answer.
