Galileo wanted to release a wooden ball and an iron ball from a height of 150 meters and
measure the duration of their fall.
He found a plane with an incline of 15° that
he could climb until he gets to an altitude of
150 m.
How far should Galileo walk up the inclined
plane?

Step-by-step explanation:

150/x=sin 15

x=150÷sin 15≈579.56 m

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
