A company sells widgets. The amount of profit, y, made by the

vfiekz [6]

Answer:

846.06 units

Step-by-step explanation:

The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation as follows :

$y = -4x^2 + 183x- 1247$ ...(1)

We need to find out the maximum amount of profit the company can make.

For maximum profit put dy/dx = 0

So,

$\dfrac{d}{dx}(-4x^2 + 183x- 1247)=0\\\\-8x+183=0\\\\x=\dfrac{183}{8}\\\\x=22.87$

Put x = 22.87 in equation (1). So,

$y = -4(22.87)^2 + 183(22.87)- 1247\\\\=846.06$

So, the maximum profit is 846.06 units.

Solving Exponential and Logarithmic Equations In Exercise, solve for x.<br> 2 In x + In(x - 2) = 0

Pani-rosa [81]

Answer:

The value of x is about 2.206.

Step-by-step explanation:

Consider the given equation is

$2\ln x+\ln (x-2)=0$

We need to find the value of x.

Using the properties of logarithm we get

$\ln x^2+\ln (x-2)=0$ $[\because \ln a^b=b\ln a]$

$\ln (x^2(x-2))=0$ $[\because \ln (ab)=\ln a+\ln b]$

$\ln (x^2(x-2))=ln 1$ $[\because \ln 1=0]$

On comparing both sides we get

$x^2(x-2)=1$

$x^3-2x^2=1$

Using graphing calculator, the real solution of the above equation is

$x\approx 2.206$

Therefore, the value of x is about 2.206.
