Question 3
Find the expression that is equivalent to log, uv
log2 u + log2 v
log, 2 + log, u + logo v
2 log, u + log2 v
2 log, u + 2 log, v
1 + log, u + log2 v

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
