It is normal for the cervix to dilate during labor. The cervix opens when there is dilatation. The cervix may begin to shrink or stretch (efface) and open as labor approaches (dilate).
As a result, the cervix is ready for the baby to enter the delivery canal (vagina). Each woman's cervix thins and opens at a different rate. The cervix may begin to slowly efface and dilate over a few weeks in certain women. On the other hand, a first-time mother frequently won't dilate until active labor begins.
Your doctor may use his or her fingers to feel the cervix toward the end of your pregnancy to see how much it has effaced and dilated. To do this, he or she will put on sterile gloves. Your cervix opens (dilates) as your uterus contracts during labor. They also assist in positioning the infant for birth.

Answer:
You're wrong, it's the bottom left
Step-by-step explanation:
x^2-49 is a difference of squares so it factors into (x+7)(x-7) which obviously cancels out with the denominator leaving x-7 left. This is the line you should graph, but keep in that x+7 is still in the denominator so x cannot be equal to -7 which means that this point should be be on the line which leaves the answer to be the one on the bottom left.

=1+sin2 A+2sin A+cos2 A/cos A(1+sin A)
=1+2sin A+1/cos A(1+sin A)
=2(1+sin A)/cos A(1+ sin A)
=2sec A
Answer:
see explanation
Step-by-step explanation:
Consider the left side
[tex]\frac{1+sinA}{cosA}[/tex] + [tex]\frac{cosA}{1+sinA}[/tex] ← combine into a single fraction
= [tex]\frac{(1+sinA)^2+cos^2A}{cosA(1+sinA)}[/tex] ← expand and simplify numerator
= [tex]\frac{1+2sinA+sin^2A+cos^2A}{cosA(1+sinA)}[/tex] [ sin²A + cos²A = 1 ]
= [tex]\frac{1+2sinA+1}{cosA(1+sinA)}[/tex]
= [tex]\frac{2+2sinA}{cosA(1+sinA)}[/tex] ← factor out 2 on the numerator
= [tex]\frac{2(1+sinA)}{cosA(1+sinA)}[/tex] ← cancel (1 + sinA) on numerator/ denominator
= [tex]\frac{2}{cosA}[/tex]
= 2secA = right side, thus verified

Answers to both subparts are shown:
(A) The fraction of games Tim wins is 4/5.(B) Tim wind has 20 games when he plays 30 games.What is a fraction?Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English. An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction.So, (A) fraction of the game Tim wins:
The number of games played is 20.The game won is 16.Then, the fraction will be:
16/204/5(B) Games Tim wins in 30 games.
The total number of games played is 30.The winning percentage is 68%.So, a number of games won:
30/100 × 680.30 × 6820.4Rounding off: 20Therefore, answers to both subparts are shown:

Answer:
105 students and 150 guests
Step-by-step explanation:
equation to find the answer are
1x + 5y = 855
x + y = 255
with
x + y = 255
x = 255 - y
now we replace x with (255 - y) into 1x + 5y = 855 to find y
1(255 - y) + 5y = 855
255 - y + 5y = 855
255 + 4y = 855
4y = 855 - 255
4y = 600
y = 150 (number of guests)
now we got y = 150, let's find x
x + y = 255
x + 150 = 255
x = 255 - 150
x = 105 (number of students)

How many degrees are on
the interior of a Polygon that
has 18 sides?
Answer:
ask yourself
Step-by-step explanation:
Answer:
160.00° Degrees
Step-by-step explanation:
To find the answer, we have to use the interior angle formula which is
(n-2)*180, where n is the number of sides. This formula gives us the sum of all interior angles in a polygon having ‘n’ sides.
For a polygon with 18 equal sides, first finding the sum of all interior angles of the polygon:-
=(n-2)*180= (18–2)*180=16*180=2880 degree.
We found the sum of all interior angles of 18 sided polygon and it is 2880 degrees.
The polygon we are considering has all sides equal, which means it is a regular polygon. So we can conclude that all of its interior angles are equal.
Sum of all eighteen angles=2880, One angle=2880/18=160 degrees.
Thus, we concluded that the interior angle of the regular eighteen sided polygon
is 160 degrees

On a coordinate plane, a point is at (1, 2) and (5, 2). Find the distance between (1, 2) and (5, 2). The points lie in the same quadrant . The distance is .
Answer:
The points lie in
✔ the same quadrant
The distance is
✔ 4 units
Step-by-step explanation:
the same quadrant
4 units
The distance between the two points (1, 2) and (5, 2) is 4 units. And both the points (1, 2) and (5, 2) lie in the same quadrant.
What is Distance between the two points?Distance between two points is the length of the line segment that connects two given points.
Formula for the distance between two points[tex]d = \sqrt{(x_{2}-x_{1} ^{2}) +(y_{2}-y_{1} ) ^{2} }[/tex]
According to the given question
We have
Two points
(1, 2) and (5, 2)
Let,
[tex](x_{1},y_{1}) = (1, 2)[/tex]
And, [tex](x_{2},y_{2} ) = (5,2)[/tex]
Therefore,
The distance between the points (1,2) and (5, 2)
= [tex]\sqrt{(5-1)^{2} +(2-2)^{2} }[/tex]
[tex]=\sqrt{(4)^{2}+0 }[/tex]
[tex]=4[/tex] unit.
Hence, the distance between the two points (1, 2) and (5, 2) is 4 units.
Since, the x coordinate and y coordinate of both the points (1,2) and (5, 2) are positive. Therefore, they both lie in the first quadrant. Hence, the points lie in the same quadrant.

What is the answer to 3/8 + 2/4
Answer:
1 1/2
Step-by-step explanation:
1.) First find the common denominator of the 2 fractions (8) 4: 4
8: 4, 8
2.) then you write a new expression with the numerator left blank and the denominator as 8 shown below in the step by step explanation. /8 + /8
3.)3/8 + 2/4 multiply by 1 both numerator and denominator for the first fraction. And multiply by 2 both numerator and denominator for the second fraction. 3/8 + 4/8.
4.) Then you add those 2 fractions which I assume you already know how by adding the numerators together, and get 12/8.
5.) You simplify 12/8 and get 1 4/8. 4/8 is equal to 1/2 so its 1 1/2.

Answer:
answer C: 140 cm
Step-by-step explanation:
If the water rises 14cm in 2 seconds, 21cm in 3 seconds etc... Then the water rises at 7cm per second. Multiply this by 20 seconds and you get 140cm
By find how high the water would be after 20 seconds, you would find out much height is increasing each second.
21 - 4 = 7
28 - 21 = 7
35 - 35 = 7, and so forth.
So, we know that 7 cm is increasing each second. You would just add 7 to the height for each second.
2 --> 14
3 --> 21
4 --> 28
5 --> 35
6 --> 42
7 --> 49
8 --> 56
9 --> 63
10 --> 70
11 --> 77
12 --> 84
13 --> 91
14 --> 98
15 --> 105
16 --> 112
17 --> 119
18 --> 126
19 --> 133
20 --> 140
Thus, after 20 seconds, the water's height would be c) 140 cm.

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 80 miles per hour. The westbound train travels at 90 miles per hour. How long will it take for the two trains to be 204 miles apart?
Do not do any rounding.
Answer:
one hour and 12 minutes
Answer:
1 hour and 12 minutes
Step-by-step explanation:
Let's say x = time it takes for the trains to be 204 miles apart.
Speed = Distance/Time,
Time = Distance/Speed,
x = 204/ (80 + 90) = 204/170 = 1 and 1/5 hours or 1 hour and 12 minutes

Answer:
b
Step-by-step explanation:
Answer:
To determine the value of X, what you would need to do is to use a trigonometric ratio, that would make use of the value of x and the side length of 12. This can either be, sin 30 or cos 60. Both of them will enable you to solve for x.
The final value for x would be either
X = 12/Sin 30
X = 12/Cos 60
Compute these in your calculator and you will find the final value in these cases.

Answer:
1) x = 41.8 deg
2) x = 64.2 deg
3) x = 51.3 deg
Step-by-step explanation:
Problem 1
For angle x, 4 is the opposite leg and 6 is the hypotenuse.
sin x = 4/6
x = sin^-1 2/3
x = 41.8 deg
Problem 2
For angle x, 14 is the adjacent leg, and 29 is the opposite leg.
tan x = 29/14
x = tan^-1 29/14
x = 64.2 deg
Problem 3
For angle xm 25 is the adjacent leg, and 40 is the hypotenuse.
cos x = 25/40
x = cos^-1 5/8
x = 51.3 deg
