This is an expontential growth, which is a growth based on f(x) = b*a^x
b = 1500
a = 1.03
x = 3
f(3)=1500*1.03^3 = 1639.10$
After three years the fridge would cost 1639.1$.
ΔABO is a right triangle with AB⊥BO. The radius of the circle is BO. The Pythagorean theorem applies.
AO² = AB² + BO²
13² = 5² + r²
169 -25 = r²
r = √144 = 12
The radius (r) is 12.
Answer:
45 degrees
Step-by-step explanation:
Let them be X and Y..
now...
yx=100 ....
y=100/y ...
now...
x+y= s....where s is their sum...
but y=100/x
now....x+100/x=s..
by differentiating both sides with respect to x..
1-100/x^2=ds/dx
but ds/dx=0..
100=x^2 ..
x=10..
so y=10
