Appreciation rate = 1.2% = 0.012
Let it take n years
300000^0.012n = 350000
taking log
0.012n * log(300000) = log(350000)
0.012n * 5.4771 = 5.5440
0.0657252 n = 5.5440
n = 84.35 years
2017 + 84.35 = 2101.35
It will be worth $350,000 in 2101
The answer is d. All you have to do is divide the reaction value by the product value. Sometimes they give you the answer is fraction form, and sometimes they give it in decimal form, which can be tricky.
Answer:
The correct answer for the question is 7
The center is at origin O(0,0).
If it contains the point, P(-8,6), then the radius r is, by Pythagoras theorem,
r=sqrt((-8)^2+6^2)=10
The general equation of a circle at centre (xc,yc) with radius r is given by
(x-xc)^2+(y-yc)^2=r^2
Substituting r=10, (xc,yc)=(0,0)
the resulting equation is therefore
(x-0)^2+(y-0)^2=10^2
or simply
x^2+y^2=100
