The graph of function g is a parabola with the vertex located at (5,9). The parabola also passes through the point (3, 1). Which of the following
is an equation in vertex form for this function?
A. g(x) = 2(x - 5)2 + 9
B. g(x) = 2(x - 5)2 -9
C. g(x) = -2(x - 5)2 + 9
D. g(x) = -2(x + 5)2 + 9

the answer would be the last one (constat) she stays at the same rat every two mintues it goes up by 0.4

step-by-step explanation:

40 x 50 = 2000

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
