we know that
Area of the circle is equal to
where
r is the radius
in this problem
therefore
the answer is the option
d. 113.04 sq. in.
Answer:
The intersection is .
The Problem:
What is the intersection point of and ?
Step-by-step explanation:
To find the intersection of and , we will need to find when they have a common point; when their and are the same.
Let's start with setting the 's equal to find those 's for which the 's are the same.
By power rule:
Since implies :
Squaring both sides to get rid of the fraction exponent:
This is a quadratic equation.
Subtract on both sides:
Comparing this to we see the following:
Let's plug them into the quadratic formula:
So we have the solutions to the quadratic equation are:
or .
The second solution definitely gives at least one of the logarithm equation problems.
Example: has problems when and so the second solution is a problem.
So the where the equations intersect is at .
Let's find the -coordinate.
You may use either equation.
I choose .
The intersection is .
If you would like to solve (- 0.5) / (- 0.5) and - 50 / (- 0.5), you can do this using the following few steps:
(- 0.5) / (- 0.5) = 0.5 / 0.5 = 1
- 50 / (- 0.5<span>) = 50 / 0.5 = 50 / (5/10) = 50 / (1/2) = 50 * 2/1 = 100
</span>
The correct results would be: (- 0.5) / (- 0.5) = 1 and - 50 / (- 0.5<span>) = 100.</span>
