The sum of the interior angles of a polygon measure 2880°. what is the name of the polygon?

Final answer:

To find three solutions to the equation y = 3x + 4, you can choose different values for x and calculate the corresponding values of y. Three solutions are (0, 4), (1, 7), and (-1, 1).

Explanation:

The equation y = 3x + 4 represents a linear equation in slope-intercept form, where the coefficient of x is the slope and the constant term is the y-intercept. To find three solutions to this equation, we can choose different values for x and calculate the corresponding values of y.

Answer:

what about y=(x - 5 to the 2nd power is it linear

The largest of the three integers is 127.

It is required to find  the largest of the three integers.

An integer is a whole number (not a fractional number) that can be positive, negative, or zero.

Given that:

Let's assume, that first number is "x", than second number will be "x + 1" and third one is "x + 2".

  x + (x + 1) + (x + 2) = 378

   x + x + 1 + x + 2 = 378  

3x + 3 = 378   

3(x + 1)  =  378    

Divide  by  3  

 x + 1  =  126    

 x = 125

The first number is 125, second number is 126 and third number is 127.

So, the largest of the three integers is 127.

Answer:

A

Step-by-step explanation:

Answer:

12 years old

Step-by-step explanation:

m = Michael

a = Margaret

m = 3a

m+6 = 2(a+6)

m+6 = 2a+12

Two equations, two unknowns, so we can use substitution.

3a+6 = 2a+12

a+6 = 12

a = 6

Plug it back in.

m = 3(6)

m = 18

When Michael was 18, Margaret was 6. So when she was born (basically when she was 0) Michael was 18-6 = 12.

Answer:

Michael was 12 years old when Margaret was born.

Step-by-step explanation:

Let Michael be x and Margaret be y.

x=3y

x+6 (years) = 2(6+y) --> x+6=12+2y --> x=6+2y

Now that we have x, substitute x=3y:

6+2y=3y --> y=6

Now we have y, substitute again with x=3(6) --> x=18

So, Michael, x, is 18 years old. Margaret, y, is 6 years old. But, to find how old Michael was when Margaret was born, do 18 (Michael's age)-6 (Margaret's age) to get 12. So, Michael was 12 years old when Margaret was born. Hope that helped, sorry if I missed something... :D

So you know that he earns $15 per hour so we can write that as 15h, h = # of hours worked

We also know he has to earn AT LEAST  $200, so putting all this together we form the inequality(=< means less than or equal to):     15h =< 200

so now we have to solve for h (number of hours worked):

15h =< 200

(divide both sides by 15)

h =< 13 1/3

So, the painter must work a minimum of 13 and 1/3 hours to earn at least $200.

Hope this helps!  :)

The  trigonometric function which represents the graph is:

         c)   [tex]f(x)=-3\cos (x-\dfrac{\pi}{2})[/tex]

From the graph we may observe that when x=π/2 we have the value of the function  f(x)= 3

Hence, we will check in which this point hold true:

a)

      [tex]f(x)=-3\sin (x-\dfrac{\pi}{2})[/tex]

Now, when x=π/2 we have:

   [tex]f(x)=-3\sin (\dfrac{\pi}{2}-\dfrac{\pi}{2})\\\\\\f(x)=-3\sin (0)\\\\\\f(x)=0\neq 3[/tex]

Hence, option: a is incorrect.

b)

[tex]f(x)=-3\cos (x-\dfrac{\pi}{2})[/tex]

Now, when x=π/2 we have:

   [tex]f(x)=-3\cos (\dfrac{\pi}{2}-\dfrac{\pi}{2})\\\\\\f(x)=-3\cos (0)\\\\\\f(x)=-3\neq 3[/tex]

Hence, option: b is incorrect.

d)

[tex]f(x)=3\sin (x-\dfrac{\pi}{2})[/tex]

Now, when x=π/2 we have:

   [tex]f(x)=3\sin (\dfrac{\pi}{2}-\dfrac{\pi}{2})\\\\\\f(x)=3\sin (0)\\\\\\f(x)=0\neq 3[/tex]

Hence, option: d is incorrect.

c)

   [tex]f(x)=-3\cos (x-\dfrac{\pi}{2})[/tex]

Now, when x=π/2 we have:

   [tex]f(x)=3\cos (\dfrac{\pi}{2}-\dfrac{\pi}{2})\\\\\\f(x)=3\cos (0)\\\\\\f(x)=3[/tex]

Similarly we will see that the value of this function matches all the points that on the graph.

        Hence, option: c is correct.

The mean of the integers -16, -27, 21, -19, 14, -3 is found by adding together all the numbers to get -30, and then dividing by the total number of values, which in this case is 6. This results in a mean of -5.

The solution to this problem falls under the branch of Mathematics known as Statistics, which is the study of collecting, analyzing, interpreting, presenting, and organizing data. The term mean is frequently used in statistics, and it refers to the average of a set of numbers. In this case, you are required to find the mean of the set of integers -16, -27, 21, -19, 14, -3.

To compute the mean, you need to follow a simple two-step process: Add together all the numbers in the set, and then divide the total by the number of items in the set. For the numbers given in your case (-16, -27, 21, -19, 14, -3), you add these together which gives you a total of -30. There are 6 numbers in the set, so the mean would be -30 divided by 6, which equals -5.

Therefore, the mean of the integers -16, -27, 21, -19, 14, -3 is -5.

Final answer:

A cubic function example is f(x) = x^3, which shows a curve with odd function symmetry that decreases with negative x values and increases with positive ones.

Explanation:

An example of a cubic function would be the function f(x) = x3. This function represents a basic cubic equation where the variable x is raised to the third power, or cubed. The graph of this function is a curve that demonstrates symmetry about the origin, with the curve decreasing for negative values of x and increasing for positive values. As x is cubed, it indicates that the function has an odd function symmetry.
