What is the equation for the line that passes through the points (4, 2) and (0, 6) ?
C(n)=1/500 n^2-n +200 where is n is the number. does the cost have a minimum or maximum value explain
Answer:
minimum
Step-by-step explanation:
The sign of the leading coefficient of a quadratic tells you whether its graph opens upward or downward. Here, the sign of 1/500 is positive, so the graph opens upward. The function will have a minimum.
_____
Additional comment
For even-degree polynomials (quadratic = degree 2), the general shape of the curve will be ∪ or ∩. The latter will result from a negative leading coefficient.
For odd-degree polynomials, the general shape of the curve will be / or \. Again, the latter results from a negative leading coefficient.
These facts can help you identify the end-behavior of a polynomial function.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of brands = 4
Number of different ways 4 brands can be arranged.
= 4!
= 4 x 3 x 2 x 1
= 24
Thus,
The number of different ways 4 brands can be arranged is 24.

Answer:
[tex]\huge\boxed{\bf\:14:17}[/tex]
Step-by-step explanation:
Given information,
Time Maria starts doing her school work = [tex]10:17[/tex]Number of hours she spends = [tex]4[/tex] hoursTime she finishes her work by = ?Since the question doesn't provide whether [tex]10:17[/tex] is in Post Meridiem(P.M) or Ante Meridiem (A.M), we'll be using the 24-hour clock format.
In the 24-hour clock format, the clock goes from 12:01 to 23:59 each day. Each full rotation of the clock from this period shows that a day has passed by.
In the above case, if Maria starts her work by [tex]10:17[/tex], then,

What would be the slope of a line that is PARALLEL to the following?
y=-4x +11
If your answer is a fraction please enter it as a decimal.
Parallel Slope =
(Someone please help me I don’t understand this helpppp)
Answer:
The slope would be -4
Step-by-step explanation:
Since the two lines are parallel, the slopes would have to be the same because the lines can't intersect. In an equation of a line, the number before the "x" is always the slope.
Answer:
The slope of a line that is parallel to y=-4x+11 is m2=-4
Step-by-step explanation:
Parallel lines
The equation of a line of slope m and y-intercept b can be expressed as:
y=mx+b
The equation of the given line is
y=-4x+11
Which means its slope is m1=-4
Two parallel lines are defined to have the same slope. If m2 is the slope of a parallel line, then:
m2=m1=-4
Then, the slope of a line that is parallel to y=-4x+11 is m2=-4

Approximate √38 to the nearest tenth.
Answer:
6.2
Step-by-step explanation:
After you plug in [tex]\sqrt{38}[/tex] into the calendar, you get 6.16441. To round to the nearest tenth, you look at the tenth and hundreth place. Since the hundreth place is a 6, which is greater than 5, the 1 in the tenths place becomes a 2, giving you 6.2.
Aubrey and Charlie are driving to a city that is 120 mi from their house. They have already traveled 20 mi, and they are driving at a constant rate of 50 mi/h. Use the function you wrote in Item 4 to complete the following:
f(1.5) = _____. The value indicates that after _____ hours of driving,
Aubrey and Charlie will have traveled _____ miles.
Answer:
1. The total distance will be equal to 20 miles plus the remaining distance which would be obtained when you multiply the speed to time t. The equation would be written as follows:
120 = 20 + 50t
2. The minimum time would be 0 hours. The maximum time is when the total distance of 120 is fully covered.
t ≤ (120 - 20)/50
t ≤ 2 hours
Thus, the domain would be 0 < t ≤ 2.
Step-by-step explanation:
Answer:
1 First blank; f(1.5)=95 2 Blank; 1.5 3 Blank; 95
Step-by-step explanation:
you use the equation f(x)=50x+20 and put 1.5 in
f(1.5)=50(1.5)+20 = f(1.5)=95
you get 95, and that is the number of miles
1.5 is number of hours
a full bottle hold 1/4 gallon of juice
:
a bottle has 1 3/4 liters. The first thing to do is convert this mixed fraction to an improper fraction. 1 equals 4/4, so 4/4+3/4=7/4, it says they want to take 6 1/4 glasses, we convert this to a fraction, we multiply 6*1/4=6/4 and this simply we have to subtract it from 7/4 which are the liters
7/4-6/4= 1/4
so we have 1/4 of a liter left over
una botella tiene 1 3/4 de litros. Lo primero que hay que hacer es convertir esta fracción mixta en fracción impropia. 1 equivale a 4/4, entonces 4/4+3/4=7/4, dice que quieren llevar 6 vasos de 1/4, esto lo convertimos en fracción, multiplicamos 6*1/4=6/4 y esto simplemente lo tenemos que restar a 7/4 que son los litros
7/4-6/4= 1/4
entonces nos sobra 1/4 de litro
