The length of a string in yards is a function ƒ(n) of the length n in inches. Write a function rule for this situation.

lesya [120]

There are 12 inches in a foot, and 3 feet in a yard, so there are 36 inches in one yard which means that yards = inches/36. So the answer should be:

f(n) = n/36

Б) 3х2 – 10 = 152 how to solve with square root

Tju [1.3M]

Answer:

$3\sqrt{6}$ and $-3\sqrt{6}$

Step-by-step explanation:

We will take numbers to one side and variables to one side eliminate the "Square" with "Square Root" and solve for the variable x. The process is shown below:

$3x^2-10=152\\3x^2=152+10\\3x^2=162\\x^2=\frac{162}{3}\\x^2=54\\x=\sqrt{54}$

Now, we need to reduce the radical by using the rule shown below:

$\sqrt{x*y}=\sqrt{x} \sqrt{y}$

Now,

$\sqrt{54}=\sqrt{6*9} =\sqrt{6} \sqrt{9} =3\sqrt{6}$

The correct answer is $3\sqrt{6}$ and $-3\sqrt{6}$

Note: squaring positive and negative makes the same answer
