Fh. = 40h + 120, fh. = $200

200 = 40h + 120
200 - 120 = 40h
80 = 40h
80/40 = h
2 = h

h = 2 hours.

Find the points on the curve y = 2x3 + 3x2 − 12x + 1 where the tangent line is horizontal. (x, y) = (smaller x-value) (x, y) = (

vesna_86 [32]

Thinking about the graph of y, the rate of change is zero whenever there is an extremum.

First, differentiate y.

$y'=6x^2+6x-12$

Next, find the zeros of y' by factoring.

$6(x^2+x-2)=0 \\ x = -2, x = 1$

Now, we substitute these x-values into the original equation to find the coordinates.

$(-2,21), (1,-6)$

How do i graph fractions? <br>please help

MissTica

Actually it's
y = $\frac{x+4}{3}$

it's a line. so 2 points is enough

choose x so that x+4 would be divisible by 3 :)
1) x = 2, then y = (2+6) / 3 = 2 - sketch point (2,2)
2) x = 5, then y = (5+4) / 3 = 3 - sketch point (5,3)
3) line goes though those points. use ruler :)
