E^0.5ln9=? no calculator

1 answer:

5 0

$e^{0.5\ln 9}=e^\ln{9^{0.5}}=9^{0.5}= \sqrt{9} =3$

Use the property of logs: a ln b = ln (b^a)
Also e and log are inverses, so the cancel each other

Riya is applying mulch to her garden. she applies it at a rate of 250 , 000 cm 3 250,000 cm 3 250, comma, 000, start text, space

Tatiana [17]

The rate in

$\frac{ {m}^{3} }{ {m}^{2} } \: is \:0.25\frac{ {m}^{3} }{ {m}^{2} }$

<h3>How to find rate is riya applying mulch in m^3/m^2 ?</h3>

given that riya applies it at a rate of 250,000 cm^3 of mulch for every m^2 of garden space.

we already know that 1m = 100cm.

so, each side of this cube is 100cm in length.

so, $100 \times 100 \times 100 \: {cm}^{3} \: in \: {m}^{3}$

To find what is the volume in cubic metres.

$\frac{250000}{10000000} = \frac{1}{4} = 0.25 \frac{ {m}^{3} }{ { m}^{2} }$

so, the rate is $0.25 \frac{ {m}^{3} }{ {m}^{2} }$

Emily was offered a job after college earning a salary of $35,000. She will get a raise

Svetlanka [38]

Answer:

Step-by-step explanation:

Salary offered to Emily after college = $35000

Rise in her salary = $2000 every year

Let she works for x years in the company,

Salary rise in her salary = $2000x

Total salary after x years = $(35000 + 2000x)

The independent variable x represents NUMBER OF YEARS and dependent variable is the TOTAL SALARY,because the SALARY depends on the NUMBER OF YEARS WORKED.

A function these variables is C(x) = 35000 + 2000x

So, C(4) = 35000 + 2000(4) = 43000, meaning 4 years later Emily will earn a salary $43000.
