Answer:

y = - $\frac{7}{2}$ cos ( $\frac{1}{2}$ x ) , y = cos ( 3x ) + 2

Step-by-step explanation:

Image 1.

The graph is reflection of cosine over x-axis and max is 3.5 ⇒ A = - $\frac{7}{2}$

Period is ( 4 π ) ⇒ B = $\frac{1}{2}$

There are no horizontal and vertical shifts ⇒ C = D = 0

y = -  $\frac{7}{2}$  cos (  $\frac{1}{2}$  x )

Image 3.

The graph of cosine shifted 2 units up only ⇒ D = 2 , C = 0

Period of the given function is $\frac{2\pi }{3}$ ⇒ B = 3

y = cos ( 3x ) + 2

What is the product? startfraction 4 k 2 over k squared minus 4 endfraction times startfraction k minus 2 over 2 k 1 endfraction

Tcecarenko [31]

The product of the expression $(\frac{4k+2}{k^2-4})* \frac{k-2}{2k+1}$ is the expression $\frac{2}{k+2}$

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the expression:

$(\frac{4k+2}{k^2-4})* \frac{k-2}{2k+1} \\\\This\ can\ be\ simplified\ to:\\\\(\frac{2(2k+1)(k-2)}{(k+2)(k-2)(2k+1)}) \\\\=\frac{2}{k+2}$

The product of the expression $(\frac{4k+2}{k^2-4})* \frac{k-2}{2k+1}$ is the expression $\frac{2}{k+2}$

The sum of two consecutive integers is 125. What is the largest of the two numbers?

ValentinkaMS [17]

Let us assume the small integer to be = x
Then
The second consecutive greater integer = x + 1
The sum of two consecutive integers is already given in the question and it is 125. based on this given information, the answer to the question can be easily reached.
So
x + x+ 1 = 125
2x + 1 = 125
2x = 125 - 1
2x = 124
x = 124/2
   = 62
Then
The largest of the two integers = x + 1
      = 62 + 1
      = 63
So 63 is the largest integer among the two consecutive integers. I hope the procedure is not very tough for you to understand.

The path that you take to go from school to the library (shown in bold) is perpendicular to the path that takes you from home to

Vadim26 [7]

The graph required to answer this question is not provided. However, the information that will be provided in this explanation will be sufficient to answer the question.

Since the two paths are perpendicular, they can be seen as the x and y axes.

Let your school to the library indicate the x direction and the path from your home to the pack be the y-axis.

if your school = x1

Library = x2

home = y1

park = y2

The slope, m, can be calculated using m = (y2 - y1)/(x2 - x1)

After getting the slope, the equation can then be modelled as the equation of a line.

y - y1 = m(x - x1)

Inserting the values of x1 and y1 will give the required equation.
