You are multiplying 2 to each term each time.
-40 is the 4th term
-40 x 2 = -80
-80 x 2 = - 160
-160 x 2 = -320
-320 x 2 = -640
-640 x 2 = -1280
-1280 x 2 = -2560
-2560 x 2 = -5120
-------------------------------------------------------------------------------------------------------------------
-5120 is your 11th term.

Answer:
(2c³ -20c² -10c) -(c² -40c +100)
Step-by-step explanation:
<u>Profit</u>
For a problem involving cost, revenue, and profit, you are expected to know that <em>profit is the difference between revenue and cost</em>. That is, if it costs you $2 to make a necklace you sell for $10, your profit is $10 -2 = $8.
<u>Problem</u>
The problem gives you polynomial expressions for revenue and cost, and asks you to combine them to make an expression for profit. In this first part, we simply show <em>how</em> we will combine them. (We presume a later part of the question will ask you to simplify the result.)
profit = revenue - cost
Substituting the given expressions, we have ...
profit = (2c³ -20c² -10c) -(c² -40c +100) . . . . . matches last choice
We know that
• The new charge was $0.50 to mail a letter weighing up to 1 ounce, and $0.21 for each additional ounce.
Based on the given information, the expression is
Where <em>x</em> represents additional ounces, and <em>y</em> represents a cost.
<h2>Hence, the function is</h2>
