a simple case for that would just be, using an equation with an imaginary value, let's do so
when you get a "solution" or zero with an "i" or an imaginary value, is just a way to say, there's really no solution, the function never touches the x-axis
Answer:There are many different answers :-) but 100, 40, 40 is one
Step-by-step explanation:
There are quite a few answers, but you need to make sure 1 angle is greater than 90 degrees. The remaining two angles should add up to less than 89 degrees and all 3 angles should total 180 degrees.
i.e. 100, 40, 40
A.) P(t) = 130t - 0.4t^4 + 1200
The population is maximum when P'(t) = 0
P'(t) = 130 - 1.6t^3 = 0
1.6t^3 = 130
t^3 = 81.25
t = ∛81.25 = 4.3 months.
Maximum population P(t)max = 130(4.3) - 0.4(4.3)^4 + 1200 = 1,622
b.) The rabbit population will disappear when P(t) = 0
P(t) = 130t - 0.4t^4 + 1200 = 0
t ≈ 8.7 months
Answer: As the number of cookies eaten increases, the calories consumed increases.
This is because the number of cookies and calories consumed have a directly proportional relationship, meaning that if one value increases, so does the other.
