Roman and Sienna read equal number of the pages of the book.

Comparison or comparing is the act of evaluating two or more things by determining the relevant, comparable characteristics of each thing, and then determining which characteristics of each are similar to the other, which are different, and to what degree.

Given that, Roman and Sienna are comparing the number of pages they’ve each read over the Winter Break. Roman said he read 40% of his book, which has a total of 200 pages. Sienna’s book has a total of 400 pages, and she read 1/5 of it.

Book read by Roman = 40% of 200

= 40 / 100 x 200

= 80 pages

Book read by Sienna = 1/5 of 400

= 400 x 1/5

= 400/5

= 80 pages

Since, both of them read equal number of pages.

Hence, Roman and Sienna read equal number of the pages of the book.

Then  p + $0.36 is an equation to represent the total cost, C, of pounds, p of oranges.

The formula for average total cost is created by dividing the sum of all production costs by the sum of all payments in money. The total-cost formula is a simple and user-friendly process that works by dividing the total production cost by the quantity of goods produced.

Together, fixed and variable costs make up the overall cost. The total cost, for instance, would be $35 if a company had a fixed cost per unit of $30 and a variable cost per unit of $5 that increased as output increased.

Then  p + $0.36 is an equation to represent the total cost, C, of pounds, p of oranges.

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.

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.

A Set is a collection of well-defined entities or elements.

A capital alphabetic symbol represents a set, and the number of elements in the finite set is represented as the cardinal number of a set in a curly bracket {…}. For example, set A is a collection of all the natural numbers, such as A = {1, 2, 3, 4, 5, 6, 7, 8,…..∞}.

Sets can be represented in three forms:

Roster Form: Set of even numbers less than 8 = {2, 4, 6}

Statement Form: A = {Set of Odd numbers less than 9}

Set Builder Form: A = {x: x = 2n, n ∈ N and 1 ≤ n ≤ 4}

Examples of sets are,

(a) Set of first 8 multiples of 7

Suppose the set of first 8 multiples of 7 is A

Set A = {7, 14, 21, 28, 35, 42, 49, 56}.

As there are 8 elements in the set, cardinal number n(A) = 8

(b) Set B = {a, e, i, o, u, j, k}

Set B = {a, e, i, o, u, j, k}. This set contains 7 elements,

Thus, the cardinal number of set B, n(B) = 7.

(c) Set C = {x | x are even numbers between 10 and 20}

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.

The slope of the line AB is 1/4, when the points are A(0, 1) and  B(1, 5).

The ratio of how much y grows as x grows by a certain amount is known as the slope of a line. The slope of a line indicates how steep it is or how much y rises as x rises. Everywhere along the line, the slope is constant (the same).

Consider a roof or a ski slope when trying to visualise the slope of a line. Ski slopes and roofs can both have extreme gradients or be relatively flat. In reality, roofs and ski slopes can both be perfectly flat (horizontal). A line might be perfectly vertical, but a ski slope or a roof are never going to be.

The slope formula is

y₂ - y₁ = m(x₂ - x₁)

Putting the values

5 - 1 = m(1 - 0)

4 = m(1)

m = 1/4

To find the value of x in a logarithmic function, you need to use the definition of logarithms, which states that log_b x is the power to which b must be raised to produce x.

In other words, if f(x) = log_b x, then b^(f(x)) = x. To find x, you simply need to raise b to the power of f(x), using the inverse of the logarithmic function, which is the exponential function. This can be done using a calculator or by using logarithmic rules and properties to simplify the expression and solve for x. It's important to remember that logarithmic functions are only defined for positive values of x and that the base b must be positive and not equal to 1.

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).

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.

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

The maximum number of minutes that it is possible to talk without spending more than $5.00 is <= 11.30

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.
