Step-by-step explanation:
using the addition formula for sine
sin(A + B) = sinAcosB + cosAsinB
note that [tex]\frac{7\pi }{12}[/tex] = [tex]\frac{\pi }{3}[/tex] + [tex]\frac{\pi }{4}[/tex] , then
sin [tex]\frac{7\pi }{12}[/tex]
= sin([tex]\frac{\pi }{3}[/tex] + [tex]\frac{\pi }{4}[/tex] )
= sin[tex]\frac{\pi }{3}[/tex]cos[tex]\frac{\pi }{4}[/tex] + cos[tex]\frac{\pi }{3}[/tex]sin[tex]\frac{\pi }{4}[/tex]
= ( [tex]\frac{\sqrt{3} }{2}[/tex] × [tex]\frac{\sqrt{2} }{2}[/tex] ) + ([tex]\frac{1}{2}[/tex] × [tex]\frac{\sqrt{2} }{2}[/tex] )
= [tex]\frac{\sqrt{6} }{4}[/tex] + [tex]\frac{\sqrt{2} }{4}[/tex]
= [tex]\frac{\sqrt{2}+\sqrt{6} }{4}[/tex]

Step-by-step explanation:
The best answer here is community. Please see the explanation below.
Ecological UnitsA species is frequently defined in biology as the biggest group of creatures in which any two individuals of the appropriate sexes or mating types may create viable offspring, usually by sexual reproduction. Ex: "A rattlesnake and a cobra are two different species of a snake." OR "The male and female cows we found are the same species."A community, also known as a biological community, is a group or association of populations of two or more distinct species that occupy the same geographical region at the same time. Ex: "There are snakes, mice, and trees in the forest community."A biome is a community of plants and animals that live naturally in a certain region and have common traits. Ex: "The continent of Africa has rich biological diversity because it contains nine biomes."A population is the whole number of inhabitants occupying an area of the same species. Ex: "Ecologists are studying the decline of the red panda population in relation to ecotourism and zoos."Please let me know if this helped!!!
How can I open my cervix naturally?
Natural methods that may help to open the cervix include acupuncture, herbs such as red raspberry leaf, exercise, sex and nipple stimulation.
There are several natural methods that may help to soften and open the cervix in preparation for childbirth, including:
Acupuncture: Acupuncture has been found to be effective in helping to prepare the cervix for labor by promoting the release of oxytocin, a hormone that can help to soften and open the cervix.
Herbs: Certain herbs, such as red raspberry leaf, can help to tone the uterus and prepare the cervix for labor.
Exercise: Regular physical activity can help to maintain good health and prepare the body for labor.
Sex: Semen contains prostaglandins which can help to soften the cervix.
Nipple stimulation: Stimulating the nipples can also cause the release of oxytocin, which can help to soften and open the cervix.
It is important to note that these methods may not work for everyone, and it is best to consult with a healthcare provider before trying any new method.
Also, It's not advisable to self-induce labor or try to open the cervix before it's time as it can cause problems for both mother and baby.

A pyramid with a square base has a volume of 42.67 cubic meters.
What is perimeter?A perimeter is a closed route that covers, surrounds, or outlines a two-dimensional form or length. The circumference of a circle or an ellipse is its perimeter. There are various practical applications for calculating the perimeter. The perimeter of a shape is the distance around its edge. A shape's perimeter is always computed by summing the lengths of each of its sides. The perimeter of a thing is the distance surrounding it. Your house, for example, has a fenced-in yard. The perimeter of the barrier is its length.
Here,
perimeter=12.8 m

Write the equation of the line in standard form:
4y=2x+9
2x - 4y + 9 is the equation of the line in standard form.
What is standard form?Ax + By=C is the typical form for linear equations involving two variables. A linear equation in standard form is, for instance, 2x + 3y=5.
Finding both intercepts of an equation in this format is fairly simple (x and y). When resolving systems of two linear equations, this form is also really helpful.
Lets write the equation of the line in standard form:
4y=2x+9
We know that standard form = Ax + By=C
⇒ 4y = 2x + 9
⇒ 2x - 4y + 9
Here,
Ax = 2x
By = -4x
C = 9
Thus, 2x - 4y + 9 is the equation of the line in standard form.

What is mean by polygon interior angle theorem? The Polygon Interior Angle Theorem states that the sum of all the interior angles of a polygon is equal to (n - 2)180 degrees, where n is the number of sides of the polygon. This theorem applies to all regular polygons, which are polygons with all sides of equal length. The theorem can be used to calculate the measure of an interior angle of a regular polygon by dividing the total sum of all the interior angles by the number of sides. For example, if a regular pentagon has five sides, the sum of the interior angles is 5(180) or 900 degrees. Therefore, the measure of each interior angle is 900/5 or 180 degrees. This theorem is also known as the Gauss-Bonnet theorem.
Solution:
Interior angle = (n-2) . 180°
(6 - 2) . 180°
Measure of Interior angle = 720°
x + 102 + 146 + 120 + 124 + 158 = 720°

The full price of the wallet that Nathan bought before the discount is $18.60
In this case, we are given that:
The total price after the discount = $17.67
Let’s assume that the full price of the wallet is X
The discount = 5% off = 0.05 X
We can find the full price by using this following formula:
Full price – discount price = total price after discount
X – 0.05X = 17.67
0.95X = 17.67
X = 17.67 : 0.95
X = 18.6

Comparing amounts is done using a ratio. A ratio demonstrates how many times one amount fits inside another or how much larger one amount is than another.

If you look at the relationship between the numbers 15:5 as is 3:1, you can see that 3 is multiplied by 5 to obtain 15 and that 1 is multiplied by 1 to get 5. The ratio, as we can see in the image, is also 3:1.
