If you are in college, this question is likely done with calculus.
a = 12
k = 0.2
v(x) = 0 at the maximum after differentiation
V(x) = kx(a - x)
The easiest way to do this is to remove the brackets.
V(x) = akx - kx^2 Substitute the constants
V(x) = 12*0.2*x - 0.2x^2
V(x)/dx = 2.4 - 0.4x = 0 at the maximum
2.4 - 0.4x = 0
0.4x = 2.4
x = 2.4/0.4
x = 6
If you don't know any calculus yet, you can do this by completing the square.
We have 2 3/4 teaspoons of honey in EACH smoothie.
We're looking for how much honey he'll use in 5 smoothies, so multiply 2 3/4 by 5.
Answer:
y=-4/3x-5 y=7/6x-5
Step-by-step explanation:
That should be your answer I have already learn this so that should be right
No, because if y is in fact 9 then the expression evaluates to which is a false hence y cannot be 9 but rather .
Hope this helps.
