Answer:
1.048
Step-by-step explanation:
The generic form of the exponential model is ...
y = a·b^x
Filling in the given values, we have ...
100 = a·b^6
184 = a·b^19
__
Dividing the second equation by the first gives ...
184/100 = (a·b^19)/(a·b^6)
1.84 = b^13 . . . . . simplify
b = 1.84^(1/13) ≈ 1.048022 . . . . find the 13th root
The growth factor is about 1.048.
The plus sign means that we have to sum all the terms inside of the second parenthesis, while the minus sign means that we have to change all the signs inside the last parenthesis:

Now we only have to gather all like terms:

First of all, we need to find the slope of the given line, writing it in the
form and reading the
coefficient:

So, the slope is 
If a line with slope
is perpendicular to a line with slope
, the following relationship holds:

So, the slope of our line must satisfy

So, we need the equation of a line with slope 1 and passing through (4,7). Given the slope
and a point
of a given line, its equation is given by

So, if you plug your values, you have

The circumference is 12.56cm and the area is 12.56cm
Answer:
Here is a generic way to set up this type of algebra problem.
d = total amount of dirt at the site (tons)
r = rate or removal (tons/hr)
t = time it takes to remove all of the dirt (hr)
d = rt
The total amount of dirt equals the removal rate times hours spent removing all the dirt.
Since you want to solve for t, divide both sides by r
t = d/r
