Anna invests $7,000 in an account that compounds interest continuously and earns 7.5%. How long will it take for her

NeX [460]

Answer:

It will take 36.1 years for her money to reach $105,000.

Step-by-step explanation:

The amount of money earned after t years in continuous interest is given by:

$P(t) = P(0)e^{rt}$

In which P(0) is the initial investment and r is the interest rate, as a decimal.

Anna invests $7,000 in an account that compounds interest continuously and earns 7.5%.

This means that $P(0) = 7000, r = 0.075$

How long will it take for her money to reach $105,000?

This is t for which P(t) = 105000.

$P(t) = P(0)e^{rt}$

$105000 = 7000e^{0.075t}$

$e^{0.075t} = \frac{105000}{7000}$

$e^{0.075t} = 15$

$\ln{e^{0.075t}} = \ln{15}$

$0.075t = \ln{15}$

$t = \frac{\ln{15}}{0.075}$

$t = 36.1$

It will take 36.1 years for her money to reach $105,000.

the length of a chord of a circle is 24 cm long and is 5 cm away from the center of the circle what is the radius of the circle

iogann1982 [59]

Answer:A chord with length 24 cm at 5 cm from the center gives a radius of 13 cm, using a half-length of 12 cm and the distance of 5 cm in Pythagoras’s theorem to find the radius.

Using the same radius and Pythagoras's theorem again, a chord 10 cm from the circle with radius 13 cm has a half-length of sqrt(69), or a full length of double that, so 2*sqrt(69).
