The number of leaves on a maple tree increased exponentially since the beginning of spring. A graph of the function contains (3, 96) and (4, 384), where x is the
number of
weeks since spring began and y is the number of leaves. Which function models the
relationship between x and y?
F = 3(2)^x
G= 4(1.5)^x
H= 4(2)^x
J= 1.5(4)^x

What is the vertex form of f(x) = x2 + 6x + 3

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
