Haley substituted the values of a, b, and c into the quadratic formula below.

x = startfraction negative (negative 10) plus or minus startroot (negative 10) squared minus 4 (7)(negative 2) endroot over 2(7) endfraction

what was haley’s function in standard form?

f(x) =
x2 + _
x + _

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125

Graph g(x)=2cosx . use 3.14 for π . use the sine tool to graph the function. graph the function by plotting two points. the first point must be on the midline and closest to the origin. the second point must be a maximum or minimum value on the graph closest to the first point.
