Four photographers are taking pictures at a school dance. Photographer A takes 25 of the pictures, Photographer B takes 4% , Pho
tographer C takes 0.29 , and Photographer D takes 27100 . Which choice lists the photographers in order from least to greatest by the amount of pictures they take?
we know that A------>25 B------> 4%----> 4/100------> 0.04x C-----> 0.29------> 29%-------------------> 0.29x D------> 27/100 --------> 27%--------------> 0.27x
[B+C+D]=4%+29%+27%--------> 60% that means A=100%-60%---------> 40% so A-------------> 0.40x A------>0.40 xB------> 0.04xC-----> 0.29xD------> 0.27x
the answer is the photographers list in order from least to greatest by the amount of pictures they take is B------> 0.04x D------> 0.27x C------> 0.29x A------> 0.40x
The vertex of a parabola is its highest or lowest point. Here, it is the lowest point, which happens right at the bottom of the U-shape—at (1, –4). Therefore, the answer is C.
