Answer:
Step-by-step explanation:
I don't think it really does grow by a constant rate. As he puts money in, the amount he puts in becomes less significant to the total.
Suppose he starts at 100 dollars.
After week one, he puts in 100 + 15 = 115 dollars.
The 15 dollars represents an increase of 15/100
After the second week, he puts in another 15 dollars. He has 115 in there already.
(15/115) * 100% = 13.04%
After the third week, he puts in another 15 dollars. (15/130 ) * 100% = 11.53
And so one
Answer:
We'd need to know the coordinates of the line segment.
So hmm notice the picture below
you have the center, and a point on the circle... all you need is the radius

then use that radius in the circle's equation
Bottom = 2x5 = 10ft
Middle = 2x6 ( 4+2) = 12
Top 4x2= 8
10ft+12ft+8ft= 30ft squared
