Suppose she plants t trees, and each one yields a apples per tree, therefore:
a = 140 - 4((t - 100)/10)
a = 140 - 0.4t + 40
a = 180 - 0.4t
If y is the total yield for the orchard, we have:
y = ta
y = t(180 - 0.4t)
y = 180t - 0.4t^2
dy/dt = 180 - 0.8t
To maximize y, set the derivative to zero:
0 = 180 - 0.8t
0.8t = 180
t = 180 / 0.8
t = 225 hope this helped
In a 30 60 90 triangle, the short side = one half the hypotenuse = 4.5
The middle side = short side * sq root of 3
So, the middle side = 4.5 * sq root of 3 (
