Suppose you love watching magic tricks performed with a deck of cards. the deck of cards is spread out in front of you in the shape of a fan. each card is 3.5 inches long, 2.5 inches wide and 0.1 inches thick. estimate the approximate surface area of the stacked cards if the deck contains 52 cards?

Y=-3x is the correct answer

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.

5/$%! /7646*\! /×+××/$÷_857$,! 5+*57478eyr7 so the correct answer is 846=8÷6÷*3. hahahah
