<u>Answer:</u>

<u>y=cos(x+\pi )</u>

<u>Step-by-step explanation:</u>

We are a given a graph from which we can clearly see that y = -1 when x  = 0.

Next, to find out which of the options is the equation of the given graph, we need to set our calculator to the radian mode and then we will put the value of x to be 0.

1. y = cos(x + pi/2) = cos(0 + pi/2) = 0

2. y = cos(x+2pi) = cos(0+2pi) = 1

3. y = cos(x+pi/3) = cos(0+pi/3) = 1/2 = 0.5

4. y = cos(x+pi) = cos(0+pi) = -1

We get y = -1 when x = 0 in equation number 4, y = cos(x+pi) = cos(0+pi) = -1. so that is the equation of the given graph.

4 consecutive numbers that add up to 8
Digiron [165]

Answer:

The answer top your question is: 1/2, 3/2, 5/2 and 7/2

Step-by-step explanation:

Data

4 consecutive numbers that add up to 8

First number = n

2nd number = n + 1

3rd number = n + 2

4th number = n + 3

Now, add them up           n + n + 1 + n + 2 + n + 3 = 8        

                                                                                          Simplify like terms

                                         4n + 6 = 8

                                         4n = 8 - 6

                                         4n = 2

                                         n = 2/4 = 1/2

First number = n         = 1/2

2nd number = n + 1    = 1/2 + 1 = 3/2

3rd number = n + 2    = 1/2 + 2 = 5/2

4th number = n + 3    = 1/2 + 3 = 7/2

A student correctly answered 35 of the 40 questions on a mathematics exam. What percent did she answer correctly?
GrogVix [38]

Answer:

87.5%

Step-by-step explanation:

To find a percentage of questions correct divide the number of correct answers by the total number of questions and then multiply that by 100.

(35/40)100=87.5

(UZ.04 LC)<br> What is the equation of a line that contains the points (2, -2) and (0, -2)?L
alexandr402 [8]

Answer:

y = - 2

Step-by-step explanation:

Find slope

(-2 - (-2))/(0-2)

(-2 + 2)//(-2)

0/2

0 ---> slope

plug in ---> y=mx+b

y=0x+b

-2=0*0+b

-2=b

equation: y=0x-2, y=-2

What is the polygon being rotated to create the blue quilt block patterns??????
never [62]

Answer:

D. Triangle is correct

Step-by-step explanation:

We are given that,

A polygon is rotated to form the blue block patterns,

As, from the figure, we see that,

The polygon being rotated has three sides.

So, the polygon is a triangle.

Thus, a triangle is rotated to form the blue block pattern.

Hence, option D is correct.

Which one do I pick, I am not sure

Answer:

  (c)  not on the circle

Step-by-step explanation:

The distance formula is ...

  d = √((x2 -x1)² +(y2 -y1)²)

For the equation of the circle, we're interested in the square of the distance between the center and the point on the circle.

  d² = r² = (x2 -x1)² +(y2 -y1)²

  r² = (3 -5)² +(2 -4)² = 4 + 4 = 8

__

We can compare this to the square of the distance to the point (9, -1).

  d² = (9 -5)² +(-1 -4)² = 16 +25 = 41

The radius and the distance to (9, -1) are clearly different, so the point does not lie on the circle.
