Help pleaseeeeeeeeeeeeeeeeee
sertanlavr [38]
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.

Naddik [55]

Answer:

2x+15=33

Step-by-step explanation:

Computation of the equation that could be solved to find the number of days Jerry has been doing sit-ups, not counting the first day

Based on the information given the EQUATION will be :

2x+15=33

Where,

x represent Jerry Sit up numbers of days excluding the first day

2x represent the additional 2 more sit ups

2x +15 represent the total number of sit up that was done after the first day

2x+15=33 represent the total 33 sit-ups that jerry did today

Therefore the EQUATION that could be solved to find the number of days Jerry has been doing sit-ups, not counting the first day will be 2x+15=33
