olchik [2.2K]

Let the smaller angle be x
The larger angle will be 3x+8
X+3x+8=180

4x=180-8=172
X=172/4
X=43
3*43+8= 137

A certain electronics manufacturer found that the average cost C to produce x DVD/Blu- ray players can be found using the equati

lilavasa [31]

Answer:

The minimum average cost is $2.80 when 163 players are built

Step-by-step explanation:

Average Cost Function

We'll assume the given function as the total cost to produce x players, and NOT the average cost since that is a different definition, as shown below.

The cost C to produce x DVD/Blu- ray players is given by the equation

$C=0.03x^2-7x+800$

The Average Cost function is defined as

$\displaystyle\bar C=\frac{C}{x}$

$\displaystyle\bar C=\frac{0.03x^2-7x+800}{x}$

$\displaystyle\bar C=0.03x-7+\frac{800}{x}$

To find the extreme value of the average cost, we must take the first derivative of the function

$\displaystyle\bar C'=0.03-\frac{800}{x^2}$

Equating to 0

$\displaystyle 0.03-\frac{800}{x^2}=0$

Solving for x

$\displaystyle x=\sqrt{\frac{800}{0.03}}$

$x=163$

The second derivative is

$\displaystyle\bar C''=\frac{1600}{x^3}$

For x=163 the second derivative is positive, thus x=163 is a minimum value. Let's compute the minimum average cost

$\displaystyle\bar C(163)=0.03\cdot 163-7+\frac{800}{163}$

$\displaystyle\bar C(163)=2.80$

The minimum average cost is $2.80

Find the sum of the predecessor of the predecessor of 2987 and successor of the greatest 3 digits number is __________

grin007 [14]

Answer:

3985

Step-by-step explanation:

Note: predecessor means a number before for example predecessor of 4 is 3. Similarly, successor is a number after for example the successor of 4 is 5.

The predecessor of the predecessor of 2987 = 2987-2 = 2985

Let 2985 be x

The greatest 3 digit number = 999

And the successor of the greatest 3 digits number would be = 999+1 = 1000

let 1000 be y

We have find the sum of x and y

= 2985+1000

= 3985
