Answer:

Mrs. Stern washed more

$\frac{7}{20}$ laundry still needs to be washed.

Step-by-step explanation:

Total amount of laundry: $\frac{20}{20}$

$\frac{20}{20} -\frac{2}{5}-\frac{1}{4} =$

$\frac{20}{20} - \frac{8}{20} -\frac{5}{20} =$

$\frac{7}{20}$ of the laundry still needs to be done.

Mrs. Stern washed $\frac{8}{20}$ of the laundry.

Her son washed $\frac{5}{20}$ of the laundry.

Mrs. Stern washed more laundry than her son.

What is the relationship between exponentials and logarithms? How can you use these to solve equations? Provide an example in yo

Sveta_85 [38]

Answer:

Exponentials and logarithms are inverses of each other.

Step-by-step explanation:

Exponentials and logarithms are inverses of each other.

For logarithmic function:

Domain = $\left ( 0,\infty \right )$ , Range = $\left ( -\infty ,\infty \right )$

Vertical asymptote is y - axis.

x - intercept is (1,0)

For exponential function:

Domain = $\left ( -\infty ,\infty \right )$ , Range = $\left ( 0,\infty \right )$

Horizontal asymptote is x - axis.

y- intercept is (0,1)

Both exponential and logarithmic functions are increasing.

For example:

Solve: $\log x=\frac{\log 5+\log 3}{\log 3^2}$

$\log x=\frac{\log 5+\log 3}{\log 3^2}\\\log x=\frac{\log (5\times 3)}{2\log 3}\,\,\left \{ \because \log (ab)=\log a+\log b\,,\,\log a^b=b\log a \right \}\\=\frac{\log 15}{2\log 3}$

$\Rightarrow \log x=\frac{\log 15}{2\log 3}\\\Rightarrow x=e^{\frac{\log 15}{2\log 3}}\,\,\left \{ \because \log x=y\Rightarrow x=e^y \right \}$
