How to solve for f^2=10000

f = 100

Step-by-step explanation:

We need to solve for f.

Since f is raised to the second power, or being squared, we need to do the reciprocal operation. That's just a fancy way of saying the opposite of what is already being done.

What is the opposite of squaring?

Finding the square root!

Find the square root:

f² = 10000

√f² = 10000

Remember, whatever you do on the left side of an equation do to the right.

√f² = √10000

Solve:

√f² = √10000

f = 100

Therefore, f is equal to one hundred.

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
