A manufacturer finds that the revenue generated by selling x units of a certain commodity is given by the function R(x) = 60x −
bonufazy [111]
R(x) = 60x - 0.2x^2

The revenue is maximum when the derivative of R(x) = 0.
dR(x)/dx = 60 - 0.4x = 0
0.4x = 60
x = 60/0.4 = 150

Therefore, maximum revenue is 60(150) - 0.2(150)^2 = 9000 - 4500 = $4,500
Maximum revenue is $4,500 and the number of units is 150 units

Step-by-step explanation:

<em>Incomplete question: Missing Attachment</em>

<em>I will answer your question with the attached histogram</em>

<em></em>

Required

Determine the number of tall buildings that had more than 60 floors

The histogram can be interpreted as follows:

\begin{array}{cccccc}{Floors} & {1-20} & {21-40} & {41-60} & {61-80} \ \\ {Buildings} & {10} & {5} & {15} & {10} \ \end{array}

More than 60 floors is represented with the following group: 61 - 80

The frequency of group 61 - 80 is 10

<em>Hence, 10 buildings had more than 60 floors</em>

Use the quadratic formula to solve x² + 9x + 10 = 0.<br><br> What are the solutions to the equation?
jok3333 [9.3K]

Answer:

-1.30\ and\ -7.70 (2 decimal places)

Step-by-step explanation:

Quadratic Formula: x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

-----------------------------------------------

x^2+9x+10=0

Plug in values:

x=\frac{-9\pm \sqrt{9^2-4\cdot \:1\cdot \:10}}{2\cdot \:1}

First value of x:

x=\frac{-9+\sqrt{41}}{2}=-1.30 (2 decimal places)

Second value of x:

x=\frac{-9-\sqrt{41}}{2}=-7.70 (2 decimal places)
