To find the volume, use this formula:
A = 0.5bhw
A = 0.5(1.5)(6)(3)
A = 0.5(9)
A = 4.5 in^3
4y - 1 = 7 / + 1 ;
4y = 8 /÷4 ;
y = 2 ;
<u>End behavior: </u>
The parent function is: f(x) = x³, which starts (from the left side) at -∞ and ends (on the right side) at +∞.
<u>Zeroes:</u>
f(x) = x³ + 2x² - 8x
0 = x³ + 2x² - 8x
0 = x(x² + 2x - 8)
0 = x(x + 4)(x - 2)
0 = x 0 = x + 4 0 = x - 2
x = 0 x = -4 x = 2
<u>Intervals:</u>
Put the zeroes in order: -4, 0, 2
since f(x) is increasing from the left then the interval from -4 to 0 is positive and the interval from 0 to 2 is negative.

There's not much more work to show sorry
To travel to Orlando is time=300/70=4.29 hours
x=hours traveller
Since there is 30 miles left in trip, the distance already traveled is 300-30=270
Set proportion
300/4.29=270/x
300x=(270)(4.29)
300x=1158.3
300/300x=1158.3/300
x≈3.86 hours ☆☆☆☆☆☆☆SOLUTION
