Answer:
Use, y = 3x-3, it might be easier to graph
Step-by-step explanation:
You can convert this equation into slope-intercept for to gramph.
y = (x – 3)2 + 3
y = 3x-6+3
y = 3x-3
Answer:

Step-by-step explanation:
Any whole number can be made into a fraction simply by putting it over 1.
A = L x W

so the with is 89.83 yards.
Answer:
x = 10 - 10sqrt(3)/3
Approximately 4.2265 cm
Volume = 1539.6 cm³
Step-by-step explanation:
Let the height be x
V = (20 - 2x)(40 - 2x)x
V = (800 - 80x - 40x + 4x²)x
V = 4x³ - 120x² + 800x
dV/dx= 12x² - 240x + 800 = 0
3x² - 60x + 200 = 0
x = [60 +/- sqrt(60² - 4(3)(200))]/6
x = [30 +/- 10sqrt(3)]/3
x = 10 +/- 10sqrt(3)/3
Approximately,
15.7735 and 4.2265
d²V/dx² = 24x - 240
For max, d²V/dx² < 0
So, x = 4.2265
V = (20 - 2x)(40 - 2x)x
Plug in x = 10 - 10sqrt(3)/3
V = 1539.600718
