Answer:
The balance will be $7,577.03.
Step-by-step explanation:
The compound interest formula is given by:

Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.

Semianually means twice a year, so 
We want to find A when
.
So



The balance will be $7,577.03.
Answer:
Step-by-step explanation:
La energía mecánica total está dada por:


En donde:
m: es la masa = 150 g
v: es la velocidad = 0.8 m/s
h: es la altura = 25 m
g: es la gravedad = 9.81 m/s²

Por lo tanto, la energía mecánica total es 36.84 J.
