The domain of the graph is 2 ≤ x ≤ 5.

Domain refers to the specific space of a website, including a domain name, associated IP address and a set of web pages that are hosted by a web server. Domain names are used to identify websites, and they are often used as a way to easily access a website. Domain names are assigned to each web server, allowing users to access the website by typing in the domain name instead of the IP address.

This means that all x-values must be greater than or equal to 2 and less than or equal to 5 in order for them to be part of the domain. This can also be written in interval notation as [2,5].

Answer: C. 3,500 grams

Step-by-step explanation:

Rodney got D as the answer by because he thought there are three zeros and adding 3 and 5 to the 1,000  35,000.

Because we know the unit rate: 1(kilogram) = 1,000(grams)

Rodney chose the incorrect answer.

Therefore, 3.5 x 1000 = 3,500 is correct

Answer:

The correct answer is C. 3500g

Step-by-step explanation:

3.5kg×1000=3500g

Rodney got answe D. by moving the decimal place of 3.5kg over by 4 places instead of 3.

His equation could have been 3.5kg×10000= 35000

Rodney did NOT choose the correct answer

The team that had the best overall record for the season is C. Eagles; they have a larger mean value of about 22 points Falcons; they have a larger mean value of about 20.9 points

The best measure of center to compare the overall records of the two teams is the mean (average) value of the points earned in each game. This is because the mean is a commonly used measure of center in statistics and provides a good overall summary of the data set.

In this case, the Eagles have a larger mean value of about 22 points (calculated by summing the points and dividing by the number of games) compared to the Falcons' mean value of about 20.9 points. So, the correct answer would be Eagles; they have a larger mean value of about 22 points

It's worth noting that using the median value in this case is not the most accurate, because this will give you a more robust representation of the center of the dataset in cases where data have outliers.

The parent function is 2 units to the left in the graph, which is shifted vertically.

What exactly is a math graph?

In mathematics, "graph" can refer to (at least) two different things. In elementary mathematics, the term "graph" designates a plot or a function graph. A graph is, in the language of mathematicians, a set of points and the connections between some subset of those points (which may be empty).

A vertical shift in a graph is a transformation that moves the graph up or down along the y-axis, without changing the shape of the graph. The amount of the shift is determined by the value of a constant in the function's equation. For example, in the equation y = f(x) + k, where k is a constant, a positive value of k will result in a shift upward and a negative value of k will result in a shift downward.

What is a trigonometric equation?

A trigonometric equation is an equation that contains one or multiple trigonometric ratios of unknown angles.

The given trigonometric equation is:

cos ([tex]\frac{x}{2}[/tex]) - sin (x) = 0

⇒ cos ([tex]\frac{x}{2}[/tex]) - 2sin ([tex]\frac{x}{2}[/tex]) cos ([tex]\frac{x}{2}[/tex]) = 0

⇒ cos ([tex]\frac{x}{2}[/tex]) [1 - 2sin ([tex]\frac{x}{2}[/tex])] = 0

Therefore,  cos ([tex]\frac{x}{2}[/tex]) = 0 = cos (90°)  ([tex]\frac{x}{2}[/tex] can't be 270°)

⇒ x = 180°

Again,  [1 - 2sin ([tex]\frac{x}{2}[/tex])] = 0

⇒ 2sin ([tex]\frac{x}{2}[/tex]) = 1

⇒ sin ([tex]\frac{x}{2}[/tex]) = 1/2

The corresponding angles and sides of the two triangles need to be given in order to prove congruence by side-angle-side.

In order to prove congruence by side-angle-side, the corresponding angles and sides of the two triangles must be given. The sides must be proportional, which means that two sides of one triangle must be equal to two sides of the other triangle, and the angles between these two sides must also be equal. In other words, if two sides of one triangle are equal to two sides of the other triangle, and the angle between those two sides is also equal, then the two triangles are congruent. This can be expressed as “If two sides and the included angle of one triangle are equal to the corresponding sides and angle of a second triangle, then the two triangles are congruent.” In order to prove congruence by side-angle-side, all of the corresponding sides and angles must be given in order to show that they are equal.

From the question, we have the following parameters that can be used in our computation:

The height of the tree can then be calculated using the following ratio expression

Tree's height : Caden's height = Caden's distance from the tree : Caden's distance from Nova

Substitute the known values in the above equation, so, we have the following representation

Tree's height : 1.2 = 6.5 : 4.2

Express as fraction

Tree's height/1.2 = 6.5/4.2

The star is 20 parsecs away which is approximately equal to 63.66 light-years away.

What is parallax angle ?

The parallax angle, also known as the parallax shift or the annual parallax, is the angle between the observer's line of sight to a celestial object at two different points in the Earth's orbit. It is a method used to measure the distance to stars and other celestial objects.

The parallax angle is defined as the angle between the observer's line of sight to the star at two different points in Earth's orbit. The distance to a star can be calculated using the formula ,

Distance = 1 / parallax angle (in arcseconds)

In this case, the parallax angle is 1/20 arcseconds, so the distance to the star is,

Distance = 1 / (1/20) = 20 parsecs

Note that one parsec is equivalent to 3.26 light-years.

So the star is 20 parsecs away which is approximately equal to 63.66 light-years away.

We can do this by factoring the equation to give (x2 + 5)(x2 − 2) = 0. This gives us the solutions x2 = −5 and x2 = 2. From this, we can find the zeros of the function, which are ±√2 and ±i.
