Suppose that the price per unit in dollars of a cell phone production is modeled by p=55−0.0125x, where x is in thousands of pho

nes produced, and the revenue represented by thousands of dollars is R=x⋅p. Find the production level that will maximize revenue.

Answer: At x = 2200 level of production, it will get maximum revenue.

Step-by-step explanation:

Since we have given that

p = 55-0.0125x

and Revenue function is given by

R=x.p\\\\R=x(55-0.0.125x)\\\\R(x)=55x-0.0125x^2

We will take the first derivative of it.

R'(x)=55-0.025x

Now,we will find the critical points :

55-0.025x=0\\\\0.025x=55\\\\x=\dfrac{55}{0.025}\\\\x=2200

and R''(x)=-0.025<0, so it will get maximum revenue.

Hence, At x = 2200 level of production, it will get maximum revenue.

1. Using your straightedge, draw a reference line, if one is not provided.
2. Copy the side of the square onto the reference line, starting at a point labeled A'.
3. Construct a perpendicular at point B' to the line through ab2.
4. Place your compass point at B', and copy the side of the square onto the perpendicular b'g. Label the end of the segment copy as point C.
5. With your compass still set at a span representing AB, place the compass point at C and swing an arc to the left.
6. Holding this same span, place the compass point at A' and swing an arc intersecting with the previous arc. Label the point of intersection as D.
7. Connect points A' to D, D to C, and C to B' to form a square.

During the regular season, a National Basketball Association team plays 82 games and a National Football League team plays 16 ga
Naddika [18.5K]

Answer:

NFL teams play 16 regular season games each year, NHL and NBA teams play 82, while MLB teams play 162-could invalidate direct comparisons of win percentages alone. As an example, the highest annual team winning percentage is roughly 87% in the NFL but only 61% in MLB and part (but not all) of that difference is undoubtedly tied to the shorter NFL regular season

A square has side length (x+5) units. What is it’s area
daser333 [38]

The area of square is x^{2}+10 x+25 square units

<h3><u>Solution:</u></h3>

Given that square has side length (x+5) units

To find: area of square

<em><u>The area of square is given as:</u></em>

\text {Area of square }=\mathrm{a}^{2}

Where "a" is the length of side

From question, length of each side "a" = x + 5 units

Substituting the value in above formula,

\text {Area of square }=(x+5)^{2}

{\text {Expanding }(x+5)^{2} \text { using the algebraic identity: }} \\\\ {(a+b)^{2}=a^{2}+2 a b+b^{2}}\end{array}

\begin{array}{l}{\text {Area of square }=x^{2}+2(x)(5)+5^{2}} \\\\ {\text {Area of square }=x^{2}+10 x+25}\end{array}

Thus the area of square is x^{2}+10 x+25 square units
