Answer: the function y = cos(2x) - 2 and the function y = cos(x) - 3
Step-by-step explanation: just took it
Function [tex]y=cos2(x)-2[/tex] and function [tex]y=cos(x)-3[/tex].
Function:A function in mathematics from a set [tex]x[/tex] to a set [tex]y[/tex] allocates exactly one element [tex]y[/tex] to each element [tex]x[/tex]. The sets [tex]x[/tex] and [tex]y[/tex] are collectively referred to as the function's domain and codomain, respectively.Initially, functions represented the idealized relationship between two changing quantities. A planet's position, for instance, depends on time. In the past, the idea was developed with the infinitesimal calculus at the end of the 17th century, and the functions that were taken into consideration until the 19th century were differentiable (that is, they had a high degree of regularity).Solution -
The function which has the same amplitude as the function [tex]y=cos(x-4)+1[/tex] and is the translation of the parent cosine is as follows:
[tex]y=cos2(x)-2[/tex][tex]y=cos(x)-3[/tex]Therefore, function [tex]y=cos2(x)-2[/tex] , and function [tex]y=cos(x)-3[/tex].

solve for s if -2=4r+2
Answer:
[tex]\boxed {s = -2 - 4r}[/tex]
Step-by-step explanation:
Solve for [tex]s[/tex]:
[tex]-2 = 4r + s[/tex]
-Switch sides:
[tex]-2 = 4r + s[/tex]
[tex]4r + s = -2[/tex]
-Subtract [tex]4r[/tex] to both sides:
[tex]4r - 4r + s = -2 - 4r[/tex]

A tree grows 10 inches each year. When the tree is 6 years old, it is 108 inches tall.
Use this information to write an equation.
How tall will the tree be in 50 years?
What is the equation of this graph?
A. y = 2x + 7
B. y = -2x + 7
C. y = -2/7x + 7
D. y = -7/2x + 7
E. y = -7/2x+ 2
Answer:
The equation would be Y= -7/2x + 7
Step-by-step explanation:
With the points given (0,7) and (2,0) we find our slope which is: -7/2. We know that our change in the y values is -7 and the change in our x values is +2. Y IS ALWAYS OVER X SO WE GET -7/2.
To find our y intercept you just look at the graph of where there's a point on the y line. For example (0,7) the 7 would be our y intercept.
So we get Y= -7/2x +7
The slope is ALWAYS put next to the variable x.
Hope this helps! :)
(Side Note: You look at the graph from left to right, so our first point would be (0,7)!)
Answer:
D. y= -7/2x +7
Step-by-step explanation:
From the graph we see that (0,7) is a point in which our line intersects on the y axis meaning that it will be our y intercept. Thus eliminating option E.
Next, we know that this graph is moving towards the left side of the graph meaning that the values will turn negative and thus meaning that the graph is decreasing, so our slope will be negative.
We know that slope is Rise/run. In thsi case, the graph doesn't have an even run of 2x or -2x because it doesn't intersect directly at those points. This eliminates A and B.
We are now left with Options C and D. Said before, 2 is our run in this graph because when observing the graph, we see that the point (2,0) is lowered by 7 and moved to the right 2. Meaning that 7 is our rise in this case and 2 would be our Run. But because it is negative pur slope is -7/2x.
Which eliminates C. Thus leaving option D as our answer

an online store charges $5 to ship one box and $10 to ship two boxes. Write an explicit formula for an arithmetic sequence to represent the amount the online store charges to ship n boxes. Use the explicit formula to determine how much you online store charges when shipping 11 boxes.
Answer:
An explicit formula for the shipping cost is = . The store charges $55 when shipping 11 items.
Step-by-step explanation:
An online store charges when shipping 11 boxes would be; 55 dollars
What is an arithmetic sequence?An arithmetic sequence is a sequence of integers with their adjacent terms differing with one common difference.
An arithmetic sequence, therefore, is defined by two parameters, viz. the starting term, and the common difference.
Given that the online store charges $5 to ship one box and $10 to ship two boxes.
We have to write an explicit formula for an arithmetic sequence to represent the amount the online store pays to ship n boxes.
From what we know so far;
y = 5n
Now Using the explicit formula to determine how much the online store charges when shipping 11 items.
y = 5(11)
y = 55 dollars
Hence, A online store charges when shipping 11 boxes would be; 55 dollars

solve 2(x-2) = 3(x+2)-8
Answer:
x = -2
Step-by-step explanation:
2(x-2) = 3(x+2)-8
Multiply the 2 and 3 out to the numbers in the parentheses. Don't multiply the 3 out to the -8 because it is outside of the parentheses.
2x-4 = 3x+6-8
Combine the 6 and -8
2x-4 = 3x-2
Subtract 2x from both sides
-4 = x-2
Add 2 to both sides
-2=x

Which situation can be modeled by the inequality m > 225? A. The community theater's auditorium can seat at most 225 people. B. The number of people who attended the mathematics conference was more than 225. C.The students need to raise at least $225 in order to pay for the bus ride to go on a field trip. D. The distance Deshawn must travel from his house to reach the Gulf Coast is less than 225 miles.
Answer:
B. The number of people who attended the mathematics conference was more than 225.Step-by-step explanation:
Given the inequality m > 225, the inequality means that m is greater than 225. Since the inequality sign does not include equal to sign, then the value of m cannot be less than and equal to 225. The situation that best fits the expression based on the explanation above is "The number of people who attended the mathematics conference was more than 225"
Emphasis should be on 'WAS MORE THAN' according to the statement. The greater sign means that the number of people will always be greater than or more than 225 representing the variable m as the number of people.
