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.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
