Answer:
$11,988
Step-by-step explanation:
A graphing calculator gives you the answer easily.
The minimum unit cost is $11,988.
__
The equation for unit cost can be put into vertex form to find the minimum.
C(x) = 0.7x^2 -210x +27738
C(x) = 0.7(x^2 -300x +150^2) +27738 -0.7(150^2)
C(x) = 0.7(x -150)^2 -11,988
This is vertex form:
C(x) = a(x -h)^2 +k . . . . . . . where (h, k) is the vertex.
The vertex of this cost function is (150, 11,988).
The minimum unit cost occurs when 150 engines are produced. That unit cost is $11,988.
Answer:
the answer is $11,988

What different and similar between Rectangle and square
Answers
Definition of Square and Rectangle
Square: A square is a closed two-dimensional plane figure with four sides. All the four sides of the square are of equal measure. Also, the four interior angles of a quadrilateral are of 9o degrees. In other words, a square is considered as a quadrilateral or a 4-sided polygon. Since all the angles are of equal measure, it is considered as an equiangular quadrilateral.
Rectangle: A rectangle is a quadrilateral with four sides. The opposite side of a rectangle is parallel to each other. It means that the opposite faces of the rectangle are of equal measure. A rectangle has four angles, each measuring about 90 degrees. As like square, a rectangle is also called an equiangular quadrilateral.

A salesman earend a $325 salery this month. His total sales were $700. If the salesman earend a total of $360. What was his commission rate?
Answers
Answer:
Commission rate= 5% of sales
Step-by-step explanation:
Giving the following information:
Fixed salary= $325
Monthly salary= $360
Sales= $700
First, we need to calculate the commissions:
Commission= monthly salary - fixed salary
Commission= 360 - 325
Commission= $35
Now, the commission rate:
Commission= commission rate* sales
35 = commission rate*700
0.05= commission rate
commission rate= 5% of sales

Answers
he would charge $4 for half a gallon of milk
Answer:
That it's confusing to you is understandable, these problems are confusing, They take a bunch of real world things and put it into abstract concepts. The graph of the line is just that, an idea of how math represents the cost of the milk.
Step-by-step explanation:
the graph you are given is a straight line, not all graphs are straight lines, but b/c it's a straight line we get to "categorize" it as linear. linear graphs are nice to work with, as compared to curvey ones. aka non-linear. There are a few famous formulas that go along with linear graphs. Remember graphs are just representations of info in a way that we can use math to understand that real thing in abstract ways.
the problem asks what is the slope of the line. Think of the idea of a mountain slope here, when we look at the graph.. and move over it like we would read, from left to right, the graph moves up hill.. or positive, so this graph is a positive slope graph. now we just need to figure out a way to say that with numbers.
often times slope is represented with the variable 'm' . why 'm' you ask? it's just a convention, it's not important which letter you use to represent slope but by convention we use 'm' There is a formula for slope that goes like this,
m = (y2-y1) / (x2-x1)
we can use that to find the slope of this line, but we already know it's positive just by quickly looking at the graph.
the x's and y's in the formula are the x and y points of some exact point on the graph that we can find just by looking at the graph. :) yes we get to make our own points. P1 and P2 ( point 1 and point 2)
somebody has already made two nice black dots, on your graph for you, let's use those two black dots, you don't have to, but those do look convenient. :)
using those two black dots and going from left to right.. I see the 1st point as P1 = (x1,y1) =( 2,10) and the second point as P2 = (x2,y2) = (4,20)
then plug those into the above fomula
m = (20-10) / (4-2)
m = 10 / 2
m = 5
yep, it's positive and steep up , that the answer to (a)
for (b)
we just need the formula called the point slope
y = mx + b
since we know m
y = 5x + b
for use b = 0
so just
y = 5x
now plug in x= 1/2, for the 1/2 gallon of milk
y = 5(1/2)
y = 2/5
that's (b) :)

One person takes up about 2.5 square feet of space. Use this value to estimate how many people can fit
in an area that is 20 feet wide and 25 feet long.
Answers
An area that is 20 feet wide and 25 feet long will be 20*25 = 500 square feet large. Division tells us how many times one number is contained within a number, so to find how many 2.5 square feet large people fit in a 500 square feet large space, we do 500/2.5 = 200 people.
