A savings account appreciates 1.5% each month. If the initial balance is $50,000, what would the total balance be after 36 month

galina1969 [7]

Answer:

$52284

Step-by-step explanation:

Given data

Rate= 1.5%

Principal= $50,000

Time = 36 months = 3 years

For the final amount A, let us apply the compound interest formula

A= P(1+r)^t

subtsitute

A=50000(1+0.015)^3

A=50000(1.015)^3

A=50000*1.045678375

A=52284

Hence the balance after 36 months (3 years) is $52284

The function of f(x)=8√x gives the speed in feet per second (ft/s) of a free falling object after it has fallen x feet (ignoring

Juliette [100K]

Answer:

c. 55.4 ft/s

Step-by-step explanation:

Speed of the object is represented by the function:

$f(x)=8\sqrt{x}$

where x represents the number of feet the object has fallen. We have to find the speed of the object after it has fallen 48 feet. This means we have to find f(x) for x = 48. Substituting x = 48 in above equation we get:

$f(48)=8\sqrt{48}\\\\ =8\sqrt{16 \times 3}\\\\ =8\sqrt{4^{2} \times 3}\\\\ = 8 \times 4 \sqrt{3}\\\\ =32\sqrt{3}\\\\ = 32 \times 1.732\\\\ = 55.4$
