The explicit rule for a sequence and one of the specific terms is given. Find the position of the given term
f(n) -(3n-3)+3;72

25 is the BLANK th term

24th term

Step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

investment b is an ordinary annuity with $3,909.64 in the account after one year.
