An object is dropped from a hot-air ballon 1296 feet above the ground. The height of the object is given by: h = -16(t-9)(t+9) w

here the height “h” is measured in feet, and the time “t” is measured in seconds. After how many seconds will the object hit the ground?

Answer:

Step-by-step explanation:

So hitting the ground i think you just set the equation equal to 0

-16(t-9)(t+9)=0

t=0,9,-9 so it will take 9 second since the negative wont be the right choice.

I hope this helps?

If $12000 is invested in an account in which the interest earned is continuously compounded at a rate of 2.5%
vladimir1956 [14]

Complete Question

If $12000 is invested in an account in which the interest earned is continuously compounded at a rate of 2.5% for 3 years

Answer:

$ 12,934.61

Step-by-step explanation:

The formula for Compound Interest Compounded continuously is given as:

A = Pe^rt

A = Amount after t years

r = Interest rate = 2.5%

t = Time after t years = 3

P = Principal = Initial amount invested = $12,000

First, convert R percent to r a decimal

r = R/100

r = 2.5%/100

r = 0.025 per year,

Then, solve our equation for A

A = Pe^rt

A = 12,000 × e^(0.025 × 3)

A = $ 12,934.61

The total amount from compound interest on an original principal of $12,000.00 at a rate of 2.5% per year compounded continuously over 3 years is $ 12,934.61.
