Answer:
The graph that matches the equation y = 2sin(x – π) + 2 is D
Step-by-step explanation:
To determine which graph matches the given equation y = 2sin(x – π) + 2. We will determine the values of y for range of values of x from -2π to 5π.
When x = -2π
From
y = 2sin(x – π) + 2
Then
y = 2sin(-2π – π) + 2
y = 2sin(-3π) + 2
(NOTE: π = 180°)
∴ y = 2sin(-540) + 2
y = 2(0) +2
y = 0 + 2
y =2
When x = -π
Then
y = 2sin(-π – π) + 2
y = 2sin(-2π) + 2
y = 2sin(-360) + 2
y = 2(0) +2
y = 0 + 2
y =2
When x = 0
Then
y = 2sin(0 – π) + 2
y = 2sin(-π) + 2
y = 2sin(-180) + 2
y = 2(0) +2
y = 0 + 2
y =2
When x = π
Then
y = 2sin( π– π) + 2
y = 2sin(0) + 2
y = 2(0) +2
y = 0 + 2
y =2
When x = 2π
y = 2sin(2π – π) + 2
y = 2sin(π) + 2
y = 2sin(180) + 2
y = 2(0) +2
y = 0 + 2
y =2
When x = 3π
y = 2sin(3π – π) + 2
y = 2sin(2π) + 2
y = 2sin(360) + 2
y = 2(0) +2
y = 0 + 2
y =2
When x = 4π
y = 2sin(4π – π) + 2
y = 2sin(3π) + 2
y = 2sin(540) + 2
y = 2(0) +2
y = 0 + 2
y =2
When x = 5π
y = 2sin(5π – π) + 2
y = 2sin(4π) + 2
y = 2sin(720) + 2
y = 2(0) +2
y = 0 + 2
y =2
The only graph that corresponds to the tested values of x is the last graph (D)
Hence, the graph that matches the equation y = 2sin(x – π) + 2 is D.
The graph of the given equation is given by option D) and this can be determined by using the rules of transformation.
Given :
Equation -- [tex]y = 2\sin(x-\pi)+2[/tex]
The following steps can be used in order to determine the graph that represents the given equation:
Step 1 - Write the given equation.
[tex]y = 2\sin(x-\pi)+2[/tex]
Step 2 - Now, draw the graph of (sin x) and then translate it by a factor of [tex]\pi[/tex] in the right direction. So, the graph obtained is the graph of [tex]\sin(x-\pi)[/tex].
Step 3 - Now, stretch the graph of [tex]\sin(x-\pi)[/tex] by a factor of 2. So, the graph obtained is the graph of [tex]2\sin(x-\pi)[/tex].
Step 4 - Now, translate the graph of [tex]2\sin(x-\pi)[/tex] by a factor of 2 in the upward direction. So, the graph obtained is the graph of [tex]2\sin(x-\pi)+2[/tex].
Therefore, the correct option is D).

A wire is bent to form semi circles as shown below. How long is the wire? Use 3.14 for pi and round your answer to the nearest hundredth if necessary
4 semi circles and the diameter is 41
Answers
======================================================
Explanation
Those 4 semicircles can be joined to form 4/2 = 2 full circles.
Each circle has diameter 41 cm.
Let's find the circumference of one circle
C = circumference, d = diameter = 41, pi = 3.14
C = pi*d
C = 3.14*41
C = 128.74
That's the perimeter of one full circle. Double it to get
2*128.74 = 257.48 cm
Which is the total length of the wire.

What is ratio & proportion ?A ratio is a divisional comparison of two quantities. It uses a fraction or quotient to represent the relationship between two numbers or quantities. For instance, we can describe the ratio 3:5 or the fraction 3/5 if we declare that there are 3 guys for every 5 ladies in a classroom.
Contrarily, the proportion equation declares that two ratios are equivalent. We can utilise proportion to solve problems with unknown amounts if we have two ratios that are equivalent.
We can use proportion to solve this problem:
If a dog eats 0.5 pound of food every 50 minutes, then in 1 minute, the dog will eat 0.5/50 = 0.01 pound of food.
Therefore, in 200 minutes, the dog will eat 0.01 x 200 = 2 pounds of food.
So the dog will have eaten 2 pounds of food after 200 minutes.

The total cost of 5 doughnuts and 6 cookies at a bakery is $11.95.The cost of each cookie is $0.95.Select the equation and its solution that can be used to determine the cost,x, of 1 doughnut.
Answers
The equation for the situation is [tex]5x+6(0.95)=11.95[/tex]
The solution to the equation is [tex]x=1.25[/tex]
First, you must set up the equation.
[tex]5x+6(0.95)=11.95[/tex]
Then, you must simplify the terms.
[tex]5x+5.7=11.95[/tex]
Next, subtract 5.7 on both sides.
[tex]5x=6.25[/tex]
Finally, divide 5 on both sides
[tex]x=1.25[/tex]
The cost of each doughnut is $1.2 and the equation is 5(0.95) + 6x = 11.95 if the total cost of 5 doughnuts and 6 cookies at a bakery is $11.95.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The total cost of 5 doughnuts and 6 cookies at a bakery is $11.95.The cost of each cookie is $0.95.
The cost of 1 doughnut is x.
Total cost = $11.95
Total cost = 5(0.95) + 6x
11.95 = 5(0.95) + 6x
Or
5(0.95) + 6x = 11.95
After solving
x = $1.2
Thus, the cost of each doughnut is $1.2 and the equation is 5(0.95) + 6x = 11.95 if the total cost of 5 doughnuts and 6 cookies at a bakery is $11.95.
The options are:
6(0.95) + 5x = 11.95
5(0.95) - 6x = 11.95
5(0.95) + 6x = 11.95
5(0.95) + 6(11.95) = x
