Ok.

She saves $5.

So, to get to $300, we divide by $5

(300/5) = 60

So it'll be 60 weeks.

Part 1:
AURORKA [14]

The following are the answers to the questions presented:

Part 1:

Vertex: <span>(<span><span>−3</span>/ 2</span>,<span> 11/2</span>)</span>

Axis of symmetry = x = -3/2

Domain = all real numbers

Range = <span>y </span><span>≤ </span>11/2

Part 2:

A quadratic equation is symmetrical around its vertex. The equation for the axis of symmetry is x = -3/2 since the equation is in terms of x. Since no value of x is undefined, then the domain of the equation is clearly all real numbers. Since the value of “a” is negative, then that means the y coordinate of the vertex is the maximum value so the range will never get above 11/2. I am hoping that these answers have satisfied your queries and it will be able to help you in your endeavors, and if you would like, feel free to ask another question.

What is 16 divided by X^2 equals 8 divided by X + 6?
zaharov [31]
Solve: \frac{16}{x^{2}} = \frac{8}{x + 6}

\frac{16}{x^{2}} = \frac{8}{x + 6}

\text{Cross multiply: } 16(x + 6) = 8x^{2}
\text{Simplify: } 2(x + 6) = x^{2}
\text{Expand: } 2x + 12 = x^{2}

\text{Solve for x: } x^{2} - 2x - 12 = 0

\text{Use the quadratic equation: } x = \frac{-b \pm \sqrt{b^{2} - 4ac}}{2a}
x = \frac{2 \pm \sqrt{4 + 48}}{2}
x = \frac{2 \pm \sqrt{52}}{2}
x = \frac{2 \pm \sqrt{13 \cdot 4}}{2}

x = \frac{2 \pm 2\sqrt{13}}{2}
\therefore x = 1 \pm \sqrt{13}

WidgCo is a company that produces and sells widgets. Let p denote the price per widget (measured in dollars), and let x be the m
Alecsey [184]

Answer:

The answer to this question can be defined as follows:

i) \bold{p(x)= -5x^2+ 217x- 1,401} \\

ii) x=22 units

iii) Maximum profit: 953.45

Step-by-step explanation:

Given value:

p(x) = 211 − 5x \\

C(x) = 1,401 + 16x

The formula for calculating the profit function value:

\to \bold{P(x)= xp(x) - C(x)}

             = x(211-5x)- 1,401 + 16x\\\\= 211x -5x^2-1,401+16x\\\\= -5x^2+ 217x- 1,401 \\

The formula for calculating the value for maximum profit:

p'(x)  =  - 10x + 217 =0

217= 10x\\\\x= \frac{217}{10}\\\\x= 21.7

So, the production level is 22 units

Maximum profit:

\to p(21.7)= - 5 (21.7)^2+217 (21.7) -1,401\\\\

           =-5 (470.89) +217 (21.7) -1,401\\\\=-2354.45+ 4708.9-1,401\\\\= 953.45
