Answer:

r = $\frac{v^2}{a}$

Step-by-step explanation:

Given

a = $\frac{v^2}{r}$ ( multiply both sides by r to clear the fraction )

ar = v² ( divide both sides by a )

r = $\frac{v^2}{a}$

Rena spent 6 days reading her book completing the same fraction of the book each day if she had a total of 8/9 of her book after

Artyom0805 [142]

Answer:

The fraction of the book that Rena read every day is $\frac{4}{27}$

Step-by-step explanation:

Rena spent 6 days reading her book completing the same fraction of the book every day and you want to know the fraction of the book she read each day. Knowing that Rena had a total of 8/9 of her book read after 6 days, then you simply divide the total amount of the book read during those days by 6, the number of days:

$\frac{8}{9}$ ÷6

To divide a fraction by a whole number, you must convert the whole number into a fraction, finding the reciprocal of that fraction, and multiply it by the first fraction. That is, you must find the reciprocal of the number that is after the division symbol; and then you multiply the first number (the one before the division symbol) by the reciprocal of the second number (the one after the division symbol). Remember that to find the reciprocal of a number, you simply have to change the numerator and denominator of the number.

Since 6 can be considered to be a fraction equal to $\frac{6}{1}$ , by inverting the number, then you get $\frac{1}{6}$

Then:

$\frac{8}{9}$ ÷6= $\frac{8}{9} *\frac{1}{6}$

Now you multiply the numerators and denominators of the fraction to get the new numerator and denominator of the final solution.

$\frac{8}{9}$ ÷6= $\frac{8}{9} *\frac{1}{6}=\frac{8*1}{9*6} =\frac{8}{54}$

Finally, simplifying the fraction:

$\frac{8}{9}$ ÷6= $\frac{8}{9} *\frac{1}{6}=\frac{8*1}{9*6} =\frac{8}{54}=\frac{4}{27}$

So:

$\frac{8}{9}$ ÷6= $\frac{4}{27}$

The fraction of the book that Rena read every day is $\frac{4}{27}$

If the domain of the square root function f(x) is x

soldier1979 [14.2K]

This question, in my opinion, is not well stated. If f(x) = √x, as the question statement seems to say, then the domain is not x<7. Rather, the domain is x≥0. If f(x) is not the square root function, but say f(x) = √(7-x) then the domain is x≤7, and for this function then the appropriate answer is d), since the x-term inside the radical has a negative coefficient.
