The revenue equation (in hundreds of millions of dollars) for barley production in a certain country is approximated by R(x) = 0

STatiana [176]

Answer:

The marginal-revenue equation is $R'(x)=0.1226x+1.1584$ .

The marginal revenue for the production of 200,000,000 bushels is $R'(x)=1.4036$ .

The marginal revenue for the production of 650,000,000 bushels is $R'(x)=9.1274$ .

Step-by-step explanation:

The derivative $R'(x)$ of the revenue function is called the marginal revenue function and is the rate of change of revenue with respect to the number of units sold.

We know the revenue function, $R(x) = 0.0613x^{2} +1.1584x+2.4813$ . Therefore, the marginal revenue function is

$R'(x)=\frac{d}{dx}R(x) = \frac{d}{dx}(0.0613x^{2} +1.1584x+2.4813)\\\\=\frac{d}{dx}\left(0.0613x^2\right)+\frac{d}{dx}\left(1.1584x\right)+\frac{d}{dx}\left(2.4813\right)\\\\R'(x)=0.1226x+1.1584$

To find the marginal revenue for the production of:

200,000,000 bushels we use x = 2, since x is in units of hundreds of million of dollars.

$R'(x)=0.1226\cdot \:2+1.1584\\\\R'(x)=0.2452+1.1584\\\\R'(x)=1.4036$

650,000,000 bushels we use x = 65, since x is in units of hundreds of million of dollars.

$R'(x)=0.1226\cdot \:65+1.1584\\\\R'(x)=7.969+1.1584\\\\R'(x)=9.1274$

vaieri [72.5K]

Find total :

$\dfrac{5}{6} + \dfrac{5}{6} + \dfrac{5}{6} = \dfrac{15}{6}$

Find pounds of nuts in each bag :

$\dfrac{15}{6} \div 8$

$\dfrac{15}{6} \times \dfrac{1}{8}$

$\dfrac{5}{16}$

$\bf \text {Answer: There are } \dfrac{5}{16} \text { pound of nuts in each bag}$

Help pleaseeeeeeeeeeeeee fast

chubhunter [2.5K]

Answer:

Step-by-step explanation:

a = 11.5×3 = 34.5 in²

b = 7.5×11.5 = 86.25 in²

c = a = 34.5 in²

d = b = 86.25 in²

lateral area = 2×34.5 + 2×86.25 = 241.5 in²
