we know that
The function cost is equal to
This is a vertical parabola open upward
The vertex is a minimum
The x-coordinate of the vertex represents the Number of airplane engines, that minimize the unit cost
The y-coordinate of the vertex is the minimum cost
Convert the given equation into vertex form
step 1
Factor 0.4
Complete the square
Rewrite as a perfect square
The vertex is the point (110,10,796)
therefore
<h2>The answer is 110 airplane engines</h2>
She is right, hope this helps
The sum of forty-five and a number n is 46.1, and the expression that can represent this can be written "45+n" where the value of n is 1.1
<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The statement that is given to us is" the sum of forty-five and a number", therefore, the expression that will represent this can be written as,
45 + n,
Now, if the value of n is 1.1. Then the sum will be,
Hence, the sum of forty-five and a number n is 46.1, and the expression that can represent this can be written "45+n" where the value of n is 1.1
