The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for x.
Answer:
x = -9
<span>Let x=apples that Andre picks
Then x/3=apples that Maria picks
And 2x=apples that Jane picks
So,
x +(x/3)+2x=840 multiply each term by 3</span>
If you would like to know how long is the banner, you can calculate this using the following steps:
1 1/3 = 4/3 times the width of the banner:
4/3 * 8 feet wide = 4/3 * 8 = 32/3 = 10 2/3 feet long
The banner is 10 2/3 feet long.
(2,3) so x=2, y=3 and h=(2^2+3^2)^(1/2)=√13
sina=3/√13, cosa=2/√13, tana=3/2
Answer:
Step-by-step explanation:
There's the two widths, x.
There's the four lengths, y.
4y+2x=600
Also, A=xy.
x=300-2y
A=y*(300-2y)
dA/dy=0= y*(-2)+(300-2y)
-2y-2y+300=0
y=300/4=150/2=75
x=300-2y=300-150=150
Then the long side is 150ft, the short side is 75ft.
Check to make sure that the sum of the lengths is 600: 300+300=600
And the maximum area is 150*75 ft2
