The revenue, in dollars, of a company that makes toy cars can be modeled by the polynomial 3x^2 + 4x – 60. The cost, in dollars, of producing the toy cars can be modeled by 3x^2 – x + 200. The number of toy cars sold is represented by x.If the profit is the difference between the revenue and the cost, what expression represents the profit?
3x – 260
3x + 140
5x – 260
5x + 140
Answers
Answer:
The expression which represents profit is:
Step-by-step explanation:
The number of toy cars sold is represented by: x.
Now, the revenue, in dollars of a company is given by the polynomial function:
and the cost, in dollars of producing the toy car is given by the polynomial expression:
Also, let P(x) denote the profit function.
It is given that:
Profit is the difference between the revenue and the cost.
i.e.
( Now we know that if the sign before the parentheses is negative then the terms inside the parentheses open up with opposite signs)
i.e.
( Since, on combining the like terms)
i.e.
P(x)=3x²+4x-60-(3x²-x+200)=5x-260

If the sum of the first 20 square numbers is 2870 then sum of the first 21 square numbers is 3311.
What is Sequence?
Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
The first square number is 1, and the sum of the first 20 square numbers is 2870.
We need to find the sum of the first 21 square numbers.
for first 20 numbers the answer is
n(n+1)(2n+1)/6
20*21*41/6 = 2870
Now we have to find the sum of first 21 square numbers.
21²=441
Now add it with 2870
2870+441=3311
Hence, the sum of the first 21 square numbers is 3311.
