F(x)= √x-5. find f-2
rodikova [14]

For this case we have:

Be a function of the form y = f (x)

Where:

f (x) = \sqrt {x-5}

If we want to find f (-2), we substitute x = -2, then:

f (-2) = \sqrt {-2-5}\\f (-2) = \sqrt {-7}

Since we have a negative root, the result will be given by complex numbers. By definition:

\sqrt {-1} = i

So:

f (-2) = \sqrt {7} i

Answer:

f (-2) = \sqrt {7} i

The line plot shows the distances some students jumped during a Field Day competition.
trapecia [35]
To answer this question here is what you would do. I can't give you the exact answer because there is not a line plot attached.

Count the number of X's above the number 5 1/2 feet. Put this number over the total number of X's you count (including the 5 1/2s).

This is your answer when you write these 2 pieces of information in fraction form.

There were 65 people waiting in two lines to buy a snowball ice drink they were joined in the line by 11 more people a total of
Pavlova-9 [17]

Answer:

67 people were still left waiting in line.

Step-by-step explanation:

If there are 65 plus 11 more, there'd be 76 people in line.

I guess the fact that it says "waiting in two lines" can be completely discarded because bottom line is 9 people got their drinks- which means that "waiting in two lines" means nothing.

76 - 9 = 67 people still left waiting in line.
