Find limit as x approaches three from the right of f of x. .
Answers
EXPLANATION
The expression means that we need to compute the limit as the function f(x) approaches 3 from the right.
We need to use the lines that comes from the right of 3 and gets as close as we want to x=3.
That is the line that has the open circle around y=3
Therefore, the limit is equal to 3

The solution is 32 because -88 + 72 = -16 and -16 times -2 = 32.D.) The solution to the equation -56 + 8x = 200 is equal to the unknown number in the sentence.
Answers
ANSWER
C.) The solution is 32 because -88 + 72 = -16 and -16 times -2 = 32.
EXPLANATION
We have that 72 less than the quotient of a number and -2 is 88.
First, let us write the equation from the sentence above.
Let the number be x.
The quotient of x and -2 means x/-2
If we subtract 72 from that quotient, the answer is -88.
Therefore, the sentence is:
[tex]\frac{x}{-2}\text{ - 72 = -88}[/tex]A cannot be correct because the equation is wrong.
B cannot be correct because the equation does not relate to the sentence given.
C is correct because if we solve for x from the equation, we get 32.
That is:
x/-2 = -88 + 72
x/-2 = -16
Multiply through by -2:
x = -16 * -2
x = 32
D cannot be correct because the equation does not relate to the sentence given.
The only correct option is C.

Answers
Given:
The coordinates of the figure ABC are,
A(-2,0)
B(-3,-4)
C(-1,-4)
To find the correct statement:
Let us find the coordinates after rotating the figure 90 degree clockwise direction.
As we know,
In a rotation of 90 degrees clockwise, every point (x,y) will be changed to (y, -x).
So, we get,
D(0,2)
E(-4, 3)
F(-4,1)
It perfectly matches with given graph.
So, Betty's statement is correct.
If we translate the figure two units up and two units right, the given point B (-3,-4) will be changed to (-1,-2) and its reflected point over the y-axis will be (1,-2).
But, this does not match with E(-4,3).
So, Veronica's statement is wrong.
Hence, Betty's statement alone is the correct one.

The apothem is a perpendicular line from the center of a regular polygon to one of the sides. O is the center of the regular polygon.
The radius of a regular polygon is a segment with one endpoint at the center and the other endpoint at one of the vertices. Thus, there are n radii in an n-sided regular polygon. The center and radius of a regular polygon are the same as the center and radius of a circle circumscribed about that regular polygon.
The perimeter of a regular polygon is a sum of the length of all the sides of the polygon.

What is the explicit function for the data in the table ?
Answers
Let's look at the info we have for each term:
term 1 = 4
term 2 = 12
term 3 = 36
term 4 = 108
term 5 = ?
Notice that term 2 (12) is obtained from the previous term 1 (4) by multiplying it by the number 3:
12 = 4 * 3
Now, term number 3 is obtained from term 2 (the previous) also by multiplying it by 3:
36 = 12 * 3
term number 4 is obtained from multiplying the previous term (term 3) by the number 3 again:
108 = 36 * 3
Now, we can conclude that if the strategy carries on, term number 5 will be the product of the pervious term (108) times 3. That is:
term 5 = 108 * 3 = 324
Now, we need to decide on which formula better describes our function:
We find that the function is better described by the formula:
[tex]f(n)=\frac{4}{3}\cdot3^n[/tex]since we can verify:
term 1 =
[tex]\frac{4}{3}\cdot3^1=4[/tex]term 2 =
[tex]\frac{4}{3}\cdot3^2=12[/tex]term 3 =

By definition, the slope of a line is:
