On a map, two locations are 0.75 centimeter apart. Their actual distance is 15 kilometers apart.

egoroff_w [7]

If you are working out the number of KM per CM them you divide the KM by the CM:
15/0.75 = 20

This means that it is 20KM per every 1CM

Hope this helps! :)

Can someone get this? Ive been trying and cant get it

Given :-

The roots of the function are 5 and -3 .

To Find :-

The Quadratic function .

Answer :-

The roots of the function are 5 and -3 . In general we can write the Quadratic function with roots π and ∆ as ,

$\sf\longrightarrow$ f(x) = ( x - π )(x-∆)

So on using this we have ,

$\sf\longrightarrow$ f(x) = ( x -5)( x -(-3))

$\sf\longrightarrow$ f(x) = (x-5)(x+3)

$\sf\longrightarrow$ f(x) = x(x-5)+3(x-5)

$\sf\longrightarrow$ f(x) = x² -5x +3x -15

$\sf\longrightarrow$ f(x) = x² -2x -15

Hence the required answer is x² -2x -15.
