A gift of 6000 to a city grew to 4000000 in 200 years. At what interest rate compounded annually would this growth occur
guapka [62]
4000000/6000=666.67
(1+r)^200=666.67
ln (1+r)^200=ln 666.67
200 ln (1+r)=ln 666.67
e^ln (1+r)=e^.03251145
1+r=1.0330457
r=0.0330457, or 3.30457% APR

While painting the side of his house, Jason positioned his ladder so that the top was 16 feet
kenny6666 [7]

Answer: 8.71\ ft

Step-by-step explanation:

Given

Ladder is 16 ft from bottom and 12 away from the base of the wall

In another case ladder is 18 ft above the ground and let say x ft away from the base of the wall

In both the cases the length of ladder remains the same

Using Pythagoras theorem, we can write

\Rightarrow 16^2+12^2=L^2\ldots(i)\\\Rightarrow 18^2+x^2=L^2\ldots(ii)\\\text{From (i) and (ii)}\\\Rightarrow 16^2+12^2=18^2+x^2\\\Rightarrow x^2=256+144-324\\\Rightarrow x^2=76\\\Rightarrow x=\sqrt{76}\\\Rightarrow x=8.71\ ft
