If f(x) varies directly with x2, and f(x) = 40 when x = 2, find the value of f(6). 36 60 120 360

pav-90 [236]

The answer is 360.
f(x) varies directly with x^2 and f(2) = 40. What does that mean?
It means this f(x) = k* x^2. We need to find k.
For x=2, f(x) = 40, this means k* x^2 = 40. BUT, x=2.
This means p* 2^2 = 40. => k = 40 / 4 = 10.
We just found what f(x) is: f(x) = 10x^2.
Now, what is the value of f(6)?
Just replace the value of k by 10. => f(6) = 10* 6^2 = 10*36 = 360

Rewrite 1/6 book over 2/3 hour as a unit rate

ollegr [7]

Answer:

$\dfrac{1}{4}$ books per hour.

Step-by-step explanation:

Given:

For $\frac{2}{3}$ hours, part of book is $\frac{1}{6}$

To find: Unit rate

Unit rate is the part of book completed in one hour.

So, we use unitary method to determine the unit rate.

Unit rate is given as:

$\textrm{Unit rate}=\frac{\textrm{Total part of book}}{\textrm{Total part of hours}}\\\textrm{Unit rate}=\frac{1}{6}\div \frac{2}{3}$

On dividing 2 fractions, the division changes to multiplication and the second fraction is reversed. This gives,

$\textrm{Unit rate}=\frac{1}{6}\div \frac{2}{3}\\\\\textrm{Unit rate}=\frac{1}{6}\times \frac{3}{2}\\\textrm{Unit rate}=\frac{1\times 3}{6\times 2}\\\textrm{Unit rate}=\frac{3}{12}\\\textrm{Unit rate}=\frac{3\div 3}{12\div 3}=\frac{1}{4}$

Therefore, the unit rate is $\dfrac{1}{4}$ books per hour.
