We know that the average price of a gallon of milk in 2000 was $2.78 and that it increased by about $0.11 per year. To find the years in which the price of a gallon of milk is between $3 and $4, we can use the following inequality:
2.78 + 0.11y < x < 4
Where x is the price of a gallon of milk in a given year y, and y represents the number of years since 2000.
The inequality can also be written as:
2.78 + 0.11y < x < 4
That can be simplified as
y > (3-2.78) / 0.11 = (0.22) / 0.11 = 2
y < (4-2.78) / 0.11 = (1.22) / 0.11 = 11
So, the years in which the price of a gallon of milk is between $3 and $4 are y > 2 and y < 11

Explain why the range of f(x)=arcsin(x) is different than g(x)=arccos(x) .
The range of a function is the set of all possible output values of the function. The range of f(x) = arcsin(x) is different than the range of g(x) = arccos(x) because the domain of each function is different.
The function f(x) = arcsin(x) is the inverse sine function, and its domain is the set of all real numbers between -1 and 1, inclusive. This is because the sine function has a range of [-1,1], and the inverse sine function takes the input value from the range of sine function and gives the corresponding angle in radians. So the range of arcsin(x) is [-π/2, π/2]
On the other hand, the function g(x) = arccos(x) is the inverse cosine function, and its domain is the set of all real numbers between -1 and 1, inclusive. This is because the cosine function also has a range of [-1,1], and the inverse cosine function takes the input value from the range of cosine function and gives the corresponding angle in radians. The range of arccos(x) is [0, π]
So, in summary, the difference in the range of f(x) = arcsin(x) and g(x) = arccos(x) is due to the difference in the domain of each function.
Answer:
Ok this is going to be a bit confusing, and I may have-actually nevermind.
Step-by-step explanation:
The range of a function is the set of all possible output values that the function can produce. The range of f(x) = arcsin(x) is different than the range of g(x) = arccos(x) because the domain of the two functions is different.
The domain of f(x) = arcsin(x) is -1 <= x <= 1. This means that x can only take on values between -1 and 1 inclusive. The range of f(x) = arcsin(x) is -(pi/2) <= f(x) <= (pi/2). This is because the arcsine function maps the interval [-1, 1] onto the interval [-(pi/2), (pi/2)].
On the other hand, the domain of g(x) = arccos(x) is also -1 <= x <= 1, but the range of g(x) = arccos(x) is 0 <= f(x) <= pi. This is because the arccosine function maps the interval [-1, 1] onto the interval [0, pi].
Both functions are defined for the same values of x, but the range of arcsin(x) is between -(pi/2) and (pi/2) while the range of arccos(x) is between 0 and pi. This means that the range of arcsin(x) is a subset of the range of arccos(x).
Another way to see this is that the arcsin(x) and arccos(x) are inverse functions, meaning that arcsin(x) = y is equivalent to arccos(sin(y)) = x and arccos(x) = y is equivalent to arcsin(cos(y)) = x.
Therefore the range of arcsin(x) will be the set of all possible y such that -1 <= sin(y) <= 1 and the range of arccos(x) will be the set of all possible y such that -1 <= cos(y) <= 1.

what is the perimeter of a sector of a circle of radius 6cm with a sector angle of 35°?
Sector perimeter equals 2 radius plus arc length. The formula for calculating arc length is: arc length = l = (/360) 2 r. As a result, the sector's perimeter is equal to 2 Radius plus ((/360) 2r).
What does a sector's and a segment's perimeter mean?The perimeter of a form is its entire outer circumference. Using what we know about determining the length of an arc, we can get the perimeter of a sector. The intersection of two radii and an arc creates a sector. We must sum these values in order to determine the perimeter. Arc length plus two is the perimeter.
How do you calculate a circle's sector area?Sector area is easily calculated by multiplying the central angle by the radius squared and dividing by two: Sector Area is equal to r2 / 2.
When the sector angle = 360° , curved length of the arc = 2πR
Hence when the central angle = 80 degree, the curved length = (80/360x(2πR)
= 1.3963 R = 1.3963 * 6 = 8.3776 cm.
Hence the perimeter = R + R + 8.3776 = 20.3776 cm

find the maximum number of minutes that it is possible to talk without spending more than
$5.00.
The maximum number of minutes that it is possible to talk without spending more than $5.00 is <= 11.30
Give a brief note on Telephone call costs?While many calls are included in the contract's inclusive minutes and hence are free of charge, some fall outside of bundle packages and are paid "per minute" or "per call" instead. The normal minimum and maximum rates for domestic calls inside the UK are listed below.
The prices listed on this page are simply illustrative and shouldn't be taken as a complete list of call costs. Actual costs vary depending on your communication provider, as well as a variety of elements such unique calling plans, the time of day, and the precise number contacted. Before dialing, you should double-check with your provider.
An x-minute call costs $2.40 + $0.23x. An inequality that states that an x-minute call costs at most $5.00 can be written as:
$2.40 + $0.23x <= $5.00
To solve for x, we first subtract $2.40 from both sides:
$0.23x <= $2.60
Then, we divide both sides by 0.23:
x <= 11.30
The solution is x <= 11.30, which means that it is possible to talk for at most 11.30 minutes without spending more than $5.00. However, since the number of minutes must be an integer, the maximum number of minutes that it is possible to talk without spending more than $5.00 is 11 minutes.

A scatter plot was made with a trend line that had an equation of y = -0.25x + 85, where y is the total number of cases of the flu and x is the total number of students who recieved the flu vaccine.
Predict how many students received a flu vaccine if a school had 65 cases of the flu.
Answer:
80 students
Step-by-step explanation:
To predict the number of students who received a flu vaccine if a school had 65 cases of the flu, we would substitute 65 for y in the equation of the trend line: y = -0.25x + 85.
y = -0.25x + 85
65 = -0.25x + 85
then we solve for x by isolating it on one side:
x = (y - 85) / -0.25
x = (65 - 85) / -0.25
x = -20 / -0.25
x = 80
So, if a school had 65 cases of the flu, it is predicted that 80 students received the flu vaccine.

Why do 3 points make a plane?.
Two unique vectors, AB and AC, may be defined by three points (A, B, and C). The cross product of the two vectors may be used as the plane's normal because they both lie on it.
It makes intuitive sense that the reason for this is that since a plane has a dimension of 2, creating one requires exactly two linearly independent vectors. The two vectors' origin and tips are the three points; if the three points were collinear, you wouldn't have two linearly independent vectors.
As long as the three points that make up a plane in a three-dimensional space are not on the same line, they can be used to define it. There is only one plane that can be reached by any three non-collinear locations. There are at least three non-collinear points on a plane. A line that contains two points that are in a plane is also in that plane. When two planes collide, a line forms at the point of intersection.

The system of linear equations 2x - y = 7, and y = 2x + 3, has no solution
In this case, Option C is correct
A system's solution is any set of x 1, x 2, x 2,..., x n values that simultaneously satisfies the above-mentioned system of linear equations. Equations are referred to as consistent if they have one or more solutions in a system of equations. Equations of the first order are linear equations. Lines in the coordinate system are defined by linear equations. It is referred to as a linear equation in one variable when the equation only contains one homogeneous variable of degree 1.Linear equations in two variables, for example, are those that have two variables in them. 2x is an example of a linear equation.To learn more about Linear equations here

D) infinite number of solutions
What are the types of sum?.
The types of sum are following :
Sum of single digit numbersSum of double digit numbersSimilarly, sum of n numbersSum of numbers is defined as the total which is result of adding numbers. Now, we have to discuss about types of sum. It is represented by plus sign (+) and summation, sigma symbol.
Type 1 : Sum of one-digit numbers : We can get the sum of 2, single-digit numbers such as 1, 2, 3, 4, 5, 6, 7, 8, 9 with different combinations. For example: 3 + 15 = 18.
Type 2 : Sum of two-digits numbers : first add the one's place digits if result is greater than 9 then transfer carry digit. After that add the ten's place digits with carry digit. For example, 35 + 56 = 91
Sum of n natural numbers : The summation formulas are used to calculate the sum of the sequence. To write the sum of more terms, say n numbers of a sequence {aₙ}, we use the summation formula instead of writing the whole sum, i.e., a₁ + a₂ + ------+ aₙ = ∑ aᵢ ; 1≤ i ≤ n. There are various types of sequences such as arithmetic sequence, geometric sequence, etc and hence there are various types of summation formulas of different sequences.
