A quantity b varies jointly with c and d and inversely with eWhen b is 18, c is 4, d is 9, and e is 6What is the constant of var
777dan777 [17]

Answer:

constant of variation = 3

Step-by-step explanation:

we know that b varies jointly with c and d

so:

b∝c∝d

and b varies inversely with e, so

b∝\frac{1}{e}

and i will call the constant of variation k, this way we can make an equation for b in the following form:

b=k\frac{cd}{e}

this satisfy that b varies jointly with c and d (if b increases, c and d also increase) and inversely with e (if b increases, e decreases)

we know that when b is 18, c is 4, d is 9, and e is 6:

b=18\\c=4\\d=9\\e=6

substituting this in our equation for b:

b=k\frac{cd}{e}\\ 18=k\frac{(4)(9)}{6}

and we solve operations and clear for the constant of variation k:

18=k\frac{36}{6}\\ 18=6k\\\frac{18}{6}=k\\ 3=k

the constant of variation is 3.

Which function is equivalent to f(x) = lnx?
11Alexandr11 [23.1K]

Answer:

f(x)=log_ex

Step-by-step explanation:

By definition, we can write ln instead of log. WHEN??

Whenever the base of the logarithm is the number "e".

Hence, when we have:

Log_e

We can write it in shortcut as:

Log_e=ln

Hence, ln x can also be written as Log_ex

Fourth answer choice is right.

Estimate the quotient to the tenths place. Then find the quotient. Round to the nearest thousandth 3)1.066 The estimate is The q
riadik2000 [5.3K]

Answer:

Estimate = 0.4

Quotient = 0.355 ---> Approximated to nearest thousandth

Step-by-step explanation:

Question like this is better answered using attachment;

See Attachment

When 1.066 is divided by 3,

The quotient is 0.3553......

When estimating to tenths,

We stop the quotient at 0.35 then round it up.

This gives 0.4

When estimating to nearest thousandth,

We stop the quotient at 0.3553 then round it up;

This gives 0.355
