Answer: 8
Explanation: 2 x 2 x 2 = 8
You expression is ( n+7 )3
P = 300 $; r = 0.06; t = 20; n = 1
A = P ( 1 + r/n)^n*t
= 300 ( 1 + 0.06) ²⁰
= 300 ( 1.06) ²⁰
= 962.14
We will have the following:
First, we write the both equations: the line and the circle:
This can be seeing as follows:
Now, we determine the point where the line intersects the circle in the first quadrant, so first, we determine the positive part of the circle, that is:
Now, we equal this expression and the line:
From this, we take the positive value, since it the only one that makes sense under the parameters required, now we find the value of y:
So, the solution is at the point:
This can be seeing as follows:
