In the given graph, line AB is reflected over the:
melamori03 [73]
Hey there!

The word reflected means when something is basically coping everything that you do. So, for example, when I look in a mirror, the mirror would reflect everything that I would do.

So, from looking at the graph above, as we should <em>remember </em>the \left[\begin{array}{ccc}\boxed{x-axis}\end{array}\right] is the axis that is (horizontal) and the y-axis is the axis that is (vertical).

So, from knowing this information of graphs, we now know that \left[\begin{array}{ccc}AB\end{array}\right] are reflecting over the (x-axis) which is the line that is (horizontal).

Your correct answer would be . . . 

\boxed{\boxed{x-axis \ would \ be \ your \ answer}}

Hope this helps you!

Assume that the total revenue received from the sale of x items is given​ by, ​R(x)equals34 ln (4 x plus 5 )​, while the total c
katen-ka-za [31]

Answer:

63 units

Step-by-step explanation:

The profit function P(x) is given by the revenue function minus the cost function:

P(x) = R(x) - C(x)\\P(x) = 34ln(x+5)-\frac{x}{2}

The number of units sold 'x' for which the derivate of the profit function is zero, is the number of units that maximizes profit:

P(x) = 34ln(x+5)-\frac{x}{2}\\P'(x) =0= \frac{34}{x+5}-\frac{1}{2}\\x+5=68\\x=63\ units

The number of units that should be manufactured so that​ profit is maximum is 63 units.
