C(n) = -6 + 5(n - 1) find the eighth term

8th term is 29

Step-by-step explanation:

⇒ c(8) = -6 + 5(8 - 1) = -6 + (5 × 7) = - 6 + 35 = 29

answer: 2530

hope this

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
