Answer:
the price before taxes was $18,229.13
Step-by-step explanation:
The coefficient of x² is is a negative 0.6, so this function has a maximum value.
the max value of a quadratic function is the value of f(x) when x=-b/2a,
in this case, a=-0.6, b=382
so x=382/1.2=
r(382/1.2)=-0.6(382/1.2)²+382*(382/1.2)
use a calculator: 60801.67 is the number I got.
Answer:
let difference be x
Step-by-step explanation:
you can solve for x by keeping the 2 statesments as conditions.
then you solve for both equations together by adding subtracting or multiplying.
eg: let x be the number.
the. proceed with conditions as equations
then solve
then your answer is here
Find slope first using slope formula.
m= (y2-y1)/(x2-X1)
m= 3/2
So the slope intercept form is
y-6= 3/2 (x-2)
30 ft/ minute=30 ft/ minute*(1 minute / 60 s)=0.5 ft/s
rate in seconds per foot=1 / (0.5 ft/s)=2 s/ ft.
Answer:2 s/ft.
