A farmer wants to sell enough grain to get at least $2,400. if the selling price is $3 per bushel, how many bushels must he sell
1 answer:
Answer:
a) m x 3 ≥ 2,400 is the formed inequality.
b) The farmer should sell at least 800 bushels to earn an amount of $2,400
Step-by-step explanation:
Here, the cost of each bushel = $3
The least money the farmer wants to earn = $2400
Let m be the number of bushels the farmer sells.
So, according to the question:
The money earned after selling m bushels at $3 each ≥ $2,400
or, m x ($3) ≥ $2,400
⇒
or, m ≥ 800
Hence, the farmer should at least 800 bushels to earn an amount of $2,400

Answer:
Explanation given below.
Step-by-step explanation:
The first step is to put the parabola in the form , which is the <em>standard form of a parabola</em>
<em />
<u>Note:</u> a is the coefficient before x^2 term, b is the coefficient before x term, and c is the independent constant term
The axis of symmetry divides the parabola symmetrically. The axis of symmetry has the equation
Where <em><u>a and b are the respective values shown above</u></em>
<em><u /></em>
So, that is how you get the axis of symmetry of any parabola.
