The graph of a sinusoidal function intersects its midline at (0,5) and then has a maximum point at (\pi,6)
Write the formula of the function, where x is entered in radians.
f(x)=
Answers
Then, we should determine whether to use a sine or a cosine function, based on the point where x=0.
Finally, we should determine the parameters of the function's formula by considering all the above.
Determining the amplitude, midline, and period
The midline intersection is at y=5 so this is the midline.
The maximum point is 1 unit above the midline, so the amplitude is 1.
The maximum point is π units to the right of the midline intersection, so the period is 4 * π.
Determining the type of function to use
Since the graph intersects its midline at x=0, we should use thesine function and not the cosine function.
This means there's no horizontal shift, so the function is of the form -
a sin(bx)+d
Since the midline intersection at x=0 is followed by a maximumpoint, we know that a > 0.
The amplitude is 1, so |a| = 1. Since a >0 we can conclude that a=1.
The midline is y=5, so d=5.
The period is 4π so b = 2π / 4π = 1/2 simplified.
[tex]f(x) = 1 sin ( \dfrac{1}{2}x)+5[/tex] = Solution
The sinusoidal function described in the question is a cosine function that has been shifted vertically by 5 units. This can be written in the form f(x) = cos(x - π) + 5.
Explanation:In the given question, we are told that a sinusoidal function intersects its midline at (0,5) and has a maximum point at (π,6). Since the function reaches its maximum at π, it implies that this is a cosine function which shifted 5 units up on the y axis.
The general form for a cosine function is f(x) = A cos(Bx - C) + D, where: A is the amplitude of the wave, B determines the period of the wave, C is the phase shift, and D is the vertical shift. Given that we reach a maximum at (π,6), the amplitude is 1 (since it rises 1 unit above the midline). The vertical shift is 5, as the function crosses at (0,5).
Considering these factors and that the function hits a maximum (as opposed to a minimum) at x = π, we can say that the cosine's phase shift is π. Thus, the function does not need to be horizontally shifted. Therefore, the function is f(x) = cos(x - π) + 5.

It's simple, we just have to express this as an equation.
x we will take it as the number of days we do not know.
so..
(0.2 M * x) = 10 M
we divide on both sides by 0.2 M.
x * 0.2 M / 0.2M = 10 M / 0.2 M
we simplify
x = 10M / 0.2 M
finally we only solve and the result of x will be the days it took.

How do i graph:
x – 3y = –12
2x – y = 1
...?
Answers
To graph the given linear equations, convert them to slope-intercept form and plot their y-intercepts and slopes on a graph to draw the lines representing each equation.
Explanation:To graph the equations:
x − 3y = − 12
2x − y = 1
You can use the following steps:
Rearrange each equation into slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.For the first equation, solve for y: y = (1/3)x + 4. For the second equation, y = 2x − 1.Plot the y-intercept of each line on the graph. For the first equation, the y-intercept is 4. For the second equation, the y-intercept is -1.Use the slope to determine another point on each line. For the first equation, from the y-intercept (0,4), go up 1 unit and right 3 units to plot another point. For the second equation, from the y-intercept (0,-1), go up 2 units and right 1 unit to plot another point.Draw a straight line through the points for each equation. These lines represent the equations on the graph.By following these steps, you will produce a graph with two lines, which could intersect at a point that represents the solution to the system of equations.
To graph the system of equations x - 3y = -12 and 2x - y = 1, convert each to slope-intercept form, plot the y-intercepts, use the slopes to determine another point for each line, and draw the lines through these points.
Explanation:To graph the system of equations given by x – 3y = –12 and 2x – y = 1, you need to follow these steps:
First, rearrange each equation into slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.For the first equation x – 3y = –12, solving for y gives us y = \frac{x}{3} + 4.For the second equation 2x – y = 1, solving for y gives us y = 2x – 1.Once the equations are in slope-intercept form, you can plot the y-intercept of each line on the y-axis, which are (0, 4) for the first equation and (0, –1) for the second equation.Then, use the slope to determine another point for each line. For the first line with a slope of \frac{1}{3}, you can move right 3 units and up 1 unit from the y-intercept. For the second line with a slope of 2, move right 1 unit and up 2 units.Draw lines through the points you have plotted for each equation. The point where the lines cross is the solution to the system of equations.With consistent practice, graphing systems of equations can become a more straightforward process.

A semiconductor manufacturing company employs 1,000 people. The average weekly salary of each employee is $750.
Select the graph that correctly shows the total cost to the company of paying its employees during a year.
Answers
Answer:
Graph A is the correct choice.
Step-by-step explanation:
Let x be the number of weeks.
We have been given that a semiconductor manufacturing company employs 1,000 people. The average weekly salary of each employee is $750.
Let us find the weekly salary for 1000 employees by multiplying 1000 by $750.
[tex]\text{The weekly salary for 1,000 employees}=1,000\times \$750[/tex]
[tex]\text{The weekly salary for 1,000 employees}=\$750,000[/tex]
Let us find amount of salaries after 52 weeks as 1 year equals 52 weeks.
[tex]\text{The amount of salaries after 52 weeks for 1,000 employees}=52*\$750,000[/tex]
[tex]\text{The amount of salaries after 52 weeks for 1,000 employees}=\$39000000[/tex]
Since at week 0, the salaries for 1000 employees will be also 0, so point (0,0) will be on the line of our graph.
Now let see which of our given graphs has point (0,0) and (52,39000000).
We can see that graph A has y-value 39 million on x equals 52, therefore, Graph A is the correct choice.

It isnt for subtraction and addition because:

The set {0,1} is closed under both addition and multiplication, but not under subtraction. Closed means that any operation between any two elements in the set produces another element in the set.
Explanation:The set {0,1} is closed under both addition and multiplication. This means that if you perform either of these operations on any two numbers from the set, the result is a number that is also within the set.
For example if you add 0 and 1 (0+1), or multiply them (0*1), the result (1 and 0 respectively) is still within the set {0,1}. However, the set is not closed under subtraction, because 0-1 gives -1, which is not in the set.

But remember it is in the ||. This means the answer will, no matter what, be positive.
So the answer is |-8|, or +8.

Now for an explanation of why the || makes it positive.
They are know as "absolute values." Absolute values will always, no matter what, be a positive number. These can be very tricky to deal with, but just remember to answer what is in the || first, and THEN do the absolute value. Remember that on a number line, the middle is always 0. And because -8 and 8 are both 8 spaces away from 0, the absolute value will be 8. This is why it is positive. You cannot be negative spaces away from something.
