Log(2t+4)=log(14-3t)

barxatty [35]

Answer:

t = 2

Step-by-step explanation:

$2t + 4 = 14 - 3t$

$5t = 10$

$t = 2$

Checking:

$log(2(2) + 4) = log(8)$

$log(14 - 3(2)) = log(8)$

V = 1¹/₃πr³
V = 1¹/₃(3.14)(2)³
V = 1¹/₃(3.14)(8)
V = 1¹/₃(25.12)
V ≈ 33.493 in³

Ubtract 2Five-sixths – 1One-third.

gayaneshka [121]

Answer:

Step-by-step explanation:

Please type numerals and punctuation for your mixed numbers.

I will have to assume that you meant 2 5/6 and 1 1/3, and that you are subtracting 2 5/6 from - 1 1/3. If that is correct, then we determine the LCD and rewrite -1 1/3 using this LCD:

-1 1/3 -1 2/6

-2 5/6 -2 5/6

----------

-3 7/6 or -4 1/6

The best calculation of this difference is -4 1/6 and the best estimate is

-1 - 3, or -4

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.
