Autumn has a different plan. She thinks the $2 for practicing with a father is fine. However, she would make $6 if he makes his
elena55 [62]

We have to triple Autumn's earning for each basket, so the table would be

\begin{array}{c|c}\text{Baskets}&\text{Earnings}\\0&2\\1&6\\2&18\\3&54\\4&162\\5&486\\6&1458\\7&4374\\\end{array}

We expect an equation like

m(b)=a\cdot x^b

where a is the initial value, and x is the multiplier. Since we start with 2$, and we triple the amount with each basket, we have

m(b)=2\cdot 3^b

This relation is exponential, because every time a new basket is made, the previous amount is multiplied by a constant. In other words, we have

\dfrac{m(b+1)}{m(b)}=3\quad \forall b\geq0

For the graph, you just need to sketch the points from the table we draw above and connect them

bonufazy [111]

Answer:

c)  Conclusion:

<em>The system of inequalities is:</em>

  • 2.5r + 4m ≤ 40
  • r ≥ 0
  • m ≥ 0

Explanation:

<em></em>

<em><u>1. Define the variables</u></em>

  • r = number of carbon road bikes
  • m = number of carbon mountain bikes

<em><u>2. List the system of inequalities</u></em>

a) Time: maximum 40 hours a week

   i) From "each road bike takes 2.5 hours to make":

  • time to make r carbon road bikes: 2.5r

   ii) From "each mountain bike takes 4 hours to make""

  • time to make m carbon mountain bikes: 4m

   iii) Constraint:

  • time ≤ 40
  • 2.5r + 4m ≤ 40

<u>b) Natural constraints:</u>

Neither r nor m can be negative:

  • r ≥ 0
  • m ≥ 0

c)  Conclusion:

The system of inequalities is:

  • 2.5r + 4m ≤ 40
  • r ≥ 0
  • m ≥ 0
