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

Answer:
a = 7
Step-by-step explanation:
The function given is defined at x=1 as ...
f(1) = 3·1² = 3
In order to make the limit from the left be 3, we must have ...
ax -4 = 3 . . . . for x=1
1a = 7 . . . . . . .add 4
The value of the constant "a" is 7.
