Katarina bought a package of 500 stickers. 25% of the stickers are hearts. The remaining stickers are stars. Select 2 statements that are true.

A. Katarina has 100 heart stickers.
B. Katarina has 375 star stickers.
C. The package contains 20 sheets of stickers
3
D.75% of the stickers are stars.
E. The number of heart stickers is the same as the number of star stickers

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

answer: the common difference is -0.10
