Answer:3x^2+2x

Step-by-step explanation

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.

According to your solution of the given system of equations, the value of y is 7.

Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.

Given a system of equation y = 2x + 11 and 3x + 2y = 8

From equation 1 we will substitute the value of y in the form of x in equation 2

=> 3x + 2(2x + 11) = 8

=> 3x + 4x + 22 = 8

=> 7x = 8 - 22

=> 7x = -14

=> x = -2

Substitute this value in equation 1

=> y = 2* -2 +11

=> y = -4 + 11

=> y = 7

therefore,  the value of the y is 7 from your solution of the system of equations given.

The required inequality is 3.5x > 63 oz, where x represents windows Savannah cleans.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

Let x be the number of windows Savannah cleans.

The amount of window cleaner Savannah uses can be represented by the equation:

3.5x = oz

To represent the inequality that Savannah uses more than 18 windows, we can write:

x > 18

This inequality states that the number of windows Savannah cleans (x) is greater than 18.

Combining both the equation and the inequality we can write

3.5x > 63 oz

It tells us that the amount of window cleaner Savannah uses (3.5x) is greater than 63 oz when she cleans more than 18 windows.

Percentage of unemployment is 58.33 % in the total household of 60,000.

Although the abbreviations "pct.", "pct.", and "pct." are also used, the percent symbol, "%," is most commonly used. A percentage is a number with no dimensions and no standard measurement.

The English word "percentage" is derived from the Latin phrase "per centum," which means "by the hundred." Percentages are fractions with a numerator of 100. In other words, it is a relationship in which the total value is always assumed to be one hundred.

Percentage calculation is the process of determining a percentage of a whole in terms of 100. There are two ways to calculate a percentage:

Using the unitary approach

by adjusting fraction's denominator to 100.

It should be noted that when the denominator is not a factor of 100, the second technique of percentage calculation isn't applied. In these situations, we employ the unitary technique.

Total number of household is 60000

Total number of household which is unemployed is 35000

Percentage of unemployment = (35000/60000) * 100 = 58.33 %

A reasonable prediction for the number of times a green or red bead will be drawn from the container of beads, after being replaced 60 times, would be 42.

A reasonable prediction for the number of times a green or red bead will be drawn from the container of beads, after being replaced 60 times, would be close to the proportion of green or red beads in the container. The container has 8 red beads and 6 green beads out of a total of 8 + 7 + 6 = 21 beads. The proportion of green or red beads is (8 + 6) / 21 = 14/21.

We can use this proportion to predict the number of times a green or red bead will be drawn from the container. By multiplying the proportion of green or red beads by the number of times the bead is replaced, we get (14/21) * 60 = 42.

In this scenario, we are using the concept of probability and proportion. The probability of drawing a green or red bead is 14/21, and by multiplying it by the number of trials (60), we get the expected number of times the green or red bead will be drawn. This concept is used in statistics and probability to make predictions based on the available data. It is important to note that this is only a prediction and actual results may vary.

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 amount of money that each team raised are;

Amount raised by Back Street location = $200

Amount raised by Main Street location = $250

Amount raised by Washington Street = $150

We are told that the main street location raised $50 more than the Back Street location. Thus;

m.s = b.s + 50    ------(eq 1)

The Washington Street location raised $50 more than half the amount raised at the Back Street location. Thus;

w.s = ¹/₂b.s + 50    -------(eq 2)

Total raised = $600. Thus;

m.s + b.s + ws = 600    -------(eq 3)

-----------------------------

Plug in b.s + 50 for m.s and ¹/₂b.s + 50 for w.s in eq 3 to get;

(b.s + 50) + (¹/₂b.s + 50) + b.s = 600

Solve for b.s;

b.s + ¹/₂b.s + b.s + 50 + 50 = 600

(5/2)b.s + 100 = 600

(5/2)b.s = 500

b.s = $200 (amount raised by Back Street location)

m.s = b.s + 50

= 200 + 50

= $250 (amount raised by Main Street location)

w.s = (1/2)b.s + 50

w.s = 100 + 50

The formula of quadratic function at vertex form is  f(x) = a(x – h)² + k

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.

And now you can identify the vertex of other quadratic functions by analyzing the function in vertex form.

So, the vertex form of a quadratic function is written as

=> f(x) = a(x – h)² + k

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 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
