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.

Answer: 20

Step-by-step explanation:

Answer:

answer is (d) (5, -2)

Step-by-step explanation:

When a triangle is translated, each point is moved the same distance in the same direction. To translate a point right, we add the amount of units to the x-coordinate, and to translate it down, we subtract the amount of units from the y-coordinate.

So for point A, the original coordinates are (1,5) and it is translated right 4 and down 7. The new coordinates of point A' will be (1+4, 5-7) = (5,-2)

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.

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 value of 'x' = 12°

A circle is a closed polygon and a two-dimensional object where every point in the plane is equally spaced from a central point. Examples are rings, discs, wheels, bangles, coins, etc.

In a circle angle at the center will always equal 360°. There is a number of circular items that we can observe in the real world.

Here we have

(x²)°, 10x°, and (5x+36)° angles made by 3 sectors in a circle

As we know the sum of the angles at the center of a circle = 360°

=> x² + 10x + 5x+36  = 360  

=> x² + 15x  +36 = 360  

=>  x² + 15x - 324 = 0

Now factorize the above equation for the 'x' value

=> x² + 27x - 12x - 324 = 0  

=> x(x + 27) - 12(x + 27) = 0

=> (x + 27) (x - 12) = 0  

=> (x + 27) = 0     or     (x - 12) = 0             144 + 96

The term vertex in math is referred as a point where two or more curved lines or edges meet.

Here as a consequence of this definition we know that the point where two lines meet to form an angle and the corners of polygons and polyhedral are vertices.

Here we need to identify the formula of quadratic function at vertex form

As we all know that If a parabola opens upward, then it has a lowest point.

Where as If a parabola opens downward, then it has a highest point.

Here this lowest or highest point is the vertex of the parabola.

Here we have take the parent function f(x) = x² has its vertex at the origin.

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

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.
