Payton does reading homework for 3/6 of an hour . He does math homework for 2/6 of an hour . What fraction of an hour does Payton spend on his homework?

The fraction of an hour Payton spend on his homework is 5/6. Adding 3/6 from his reading homework and 2/6 from his math homework. If you also want to find how much minute he spend doing his homework it is 50 minutes. Every hour has 60 minutes. 20+30=50 which means that Payton also spend 50 minutes on his homework.

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
