Last week, the members of a weight loss support group collectively weighed 2,900 pounds. They just weighed in again and are now

Doss [256]

Answer:

2,784 lbs

Step-by-step explanation:

2900/100=29 (that is 1% of the 2900)

29*4=116 (that is 4% of 2900; how much weight they lost)

2900-116=2784 (current weight)

Which is the simplified form of (2ab/a^-5b^2)^-3?

olchik [2.2K]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

$(\frac{2ab}{a^{-5}b^2})^{-3}$

We will use law of exponents :

$(\frac{2ab}{a^{-5}b^2})^{-3}\\\\=(\frac{a^{-5}b^2}{2ab})^3\text{ }\because (a^m)^{-1}=\frac{1}{a^m}\\\\=\frac{a^{-15}b^{6}}{8a^3b^3}\text{ }\because (a^m)^n=a^{mn}\\\\=\frac{b^{6-3}}{a^{3+15}}\\\\=\frac{b^3}{8a^{18}}$

So, the simplified form is

$\frac{b^3}{8a^{18}}$

Hence, First option is correct.

Fred decides to think about retirement and invests at the age of 26. He invests $15,000 and hopes the investment will be

fgiga [73]

Answer:

Step-by-step explanation:

Future value with continuous compounding ; FV = $Pe^{rt\\ } \\ 900,000 = 15,000e^{38r} \\ \\ \frac{900,000}{15,000} =e^{38r\\ }\\ \\ \\ 60 =e^{38r}$

Introduce <em>ln </em>on both sides of the equation

ln 60 = ln $e^{38r}$

note: ln $e^{x} = x$

Next, solve the equation;

4.09 = 38r

Divide both sides by 38 to solve for r;

4.09/38 = r

r= 0.107746 or 10.7746%

Therefore the rate would be 10.775% to the nearest a tenth of a percent.
