A company’s total cost from manufacturing and selling x units of their product is given by: y = 2x2 – 600x + 49,000. How many un

ale4655 [162]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

$y=2x^2-600x+49000$

We need to find the number of units in order to minimize cost.

We first derivative w.r.t. x,

$y'=4x-600$

For critical points:

$y'=0\\\\4x-600=0\\\\4x=600\\\\x=\dfrac{600}{4}\\\\x=150$

Now, we will check whether it is minimum or not.

We will find second derivative .

$y''=4>0$

So, it will yield minimum cost.

Minimum cost would be

$y(150)=2(150)^2-600\times 150+49000\\\\y(150)=\$4000$

Hence, At 150 units, minimum cost = $4000

Therefore, Option 'c' is correct.

In a reflection across the x axis a given coordinate (2,-1) transforms itsself into which of the following?

goldfiish [28.3K]

Answer:

(2, 1)

Step-by-step explanation:

In a reflection across the x-axis, the x coordinate will stay the same but the y coordinate will be the negative version of the original number.

This means (2, -1) will change to (2, 1)

Expression A: (2k + 8) + (5k + 10)

Dmitriy789 [7]

k = 3

Expression A:

$(2k + 8) + (5k + 10) = 2k + 8 + 5k + 10 = 7k + 18 = 7*3 + 18 = 21 + 18 = 39$

Expression B:

$76 + 18= 94$
