Regular pentagon qrstu has a side length of 12 cm and an area of about 248 square cm. regular pentagon vwxyz has a perimeter of 140 cm. find the area of vwxyz. round to the nearest tenth. a. 578.7 square cm b. 912.4 square cm c. 1,350.2 square cm d. 2,893.3 square cm

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
