How do you find the domain and range of a square root graph?
Domain and range of a square root graph is [0, ∞) and [0, ∞) respectively.
Domain of a function:
The domain of a function is the set of input values (x) for which it produces an output value.
Range of a function:
The set of all output values of a function.
Like if we consider a function [tex]y = f(x)[/tex]
then input inside function that is x is know as domain of function
output of function that is y is known as range of function.
First we write square root function as y = [tex]\sqrt{x}[/tex]
So inside root negative numbers are not allowed so value of x should be positive numbers means x>=0.
So domain of square root function [0, ∞).
Output of square root function is always positive so range of square root function is also [0,∞).

There were 110 people at the concert. If 55% of the seats were filled, how many seats are in the auditorium?
There are seats in the auditorium.
Answer:61
Step-by-step explanation:
Answer:
200
Step-by-step explanation:
Because there were 110 people at the concert, that means only 110 seats were filled. So we can think of the problem as its own equation if we word it like this:
110 is 55% of how many seats
110 = 0.55 x ?
Now to solve by dividing 110 by 0.55
110/0.55 = 200
There are 4,500 cities on planet Purple. The planetary government takes a random sample of 350 cities and finds that the average number of complaints about feral cats from the sample was 3.4 ± 0.49. Which of the following is an estimate of the total number of feral cat complaints for planet Purple?
A) Between 1018.5 and 1361.5 complaints B) Between 171.5 and 1190 complaints C)Between 13,095 and 17,505 complaints D) Between 2,205 and 15,300 complaints
Based on the margin of error, an estimate of the total number of feral cat complaints for planet Purple is A. Between 1018.5 and 1361.5 complaints.
What is the error margin?The statistical difference between the predicted or estimated results and the actual results is displayed by the margin of error.The difference between the sample estimate's upper and lower bounds is represented by the margin of error.One defines a degree of confidence or the confidence interval in the sample findings using the margin of error.4,500 cities make up the entire population of planet Purple.
350 cities make up the random sample.
Average complaints are 3.4.
Error or margin = 0.49
[350 x (3.4 + 0.49)] Upper limit = 1,361.5
Lower limit: 1,081.5 (350 times (3.4 - 0.49).
As a result, Option A's estimated number of feral cat complaints floats above the error margin.

Which is an example of AAS congruence theorem?
Given ▲ ABC and ▲DEF are the examples of AAS congruence theorem.
According to the AAS, or Angle Angle Side congruence rule, two triangles are said to be congruent if two pairs of corresponding angles and the opposite or non-included sides are equal to one another.
The sides are not included between the angles but rather run in either direction of the angles, whereas the angles are sequential and corresponding in nature.
let's consider 2 triangles ▲ ABC , ▲DEF.
A at top B left C right . D at top E left F right side
∠B = ∠E
∠C = ∠F
AB = DE.
We can see that ∠B = E and ∠C = F if we superimpose the two triangles on top of one another. The lengths of the excluded sides, AB and DE, are also equal. As a result, we can state that ABC ≅ DEF.

solve the following equation: x/7-6=-x/6+5
By solving the given equation x/7 - 6 = - x/6 + 5 we get x value = 462/13.
What is called the equation?
An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra. Algebra is used in mathematics when you do not know the exact number in a calculation.Given that :
x/7 - 6 = - x/6 + 5
Multiply the denominators with numerator on both sides
x / 7 - 6(7) = - x / 6 + 5(6)
x - 42 / 7 = - x + 30 / 6
Multiply both denominators with numerator on both sides
6 (x - 42) = 7 (- x + 30)
Multiply 6 and 7 inside the bracket
6x - 252 = - 7x + 210
Separate x terms and constant terms
6x + 7x = 210 + 252
13x = 462
x = 462 / 13
Therefore, x = 462 /13

Does dilation change the shape of the image?
No, The dilation doesn't change the shape of the image
Dilation is a type of a transform where an image size either increase or decrease but has the same shape as the original. In other words, the dilation is similar to the original.
All dilations have a center and a scale factor. The center is the point of reference for the dilation (like the vanishing point in a perspective drawing)
Scale factor tells us how much the figure stretches or shrinks. A scale factor is typically labeled "k" and is always greater than zero. It is the ratio of the sizes of the original figure with the dilated figure
The only change in the dilation process is that the distance between the points changes. It means that the length of the sides of the original image and the dilated image may vary.
Therefore , Dilation doesn't changes the shape

suppose the scores of a standardized test are normally distributed. if the population standard deviation is 2 points, what minimum sample size is needed to be 90% confident that the sample mean is within 1 point of the true population mean?
The minimum sample size is 11 needed to be 90% confident that the sample mean is within 1 point of the true population mean.
What is the mean?
Mean, in terms of math, is the total added values of all the data in a set divided by the number of data in the set.Given:
Standard deviation, σ = 2points
Confidence level = 90%
Sample mean, ε = 1 point
At 90% confidence level
1 - α = 0.90
α = 1 -0.90
α = 0.10
α/2 = 0.05
Zα / 2 = Z₀.₀₅
= 1.645
To find n
n = (Zα / 2 )*(σ)²
= (1.645)² * (2)² / (1)²
= (2.706) * 4
= 10.8241
n = 11
Hence, the minimum sample size is 11 needed to be 90% confident that the sample mean is within 1 point of the true population mean.

determine the intervals on which the function is increasing decreasing and constant
The interval on which the graph is increasing and decreasing are ( -∞,3] and [3,∞) respectively.
There is no interval where the function is constant.
In order to solve this question we need to study the graph attached,
From the graph, we could see that the plotting of the graph is starting from the negative axes and we could observe an increasing slope in the function, and the increment stopped after reaching point B(3,0), we can also observe that the value of the y-axis increases with that of the x-axis.
The interval at B(0,3) must be wrote down as ( -∞,3]
Again we could see a sudden drop in the slope of the function of the graph as the slope of the graph this time starts decreasing and moves to infinity and again we could observe that the value of the x-axis starts decreasing with the decrease in the value of the y-axis.

Find the missing side of the triangle.
X
8.3 m
5.9 m
The missing side of the triangle is approximately 10.2 m. This solution assumes that the given sides form a right triangle.
How to find side of triangle ?To find the missing side of a triangle, you can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
The formula for the Pythagorean theorem is:
a^2 + b^2 = c^2
where a and b are the lengths of the two sides of the triangle and c is the length of the hypotenuse.
The lengths of two sides of the triangle, 8.3 m and 5.9 m, and you need to find the length of the third side (the hypotenuse).
You can use the Pythagorean theorem to solve for the missing side as follows:
c^2 = a^2 + b^2
c^2 = 8.3^2 + 5.9^2
c = sqrt(8.3^2 + 5.9^2)
c = sqrt(69.29 + 34.81)
c = sqrt(104.1)
c = 10.2 m
Therefore, the missing side of the triangle is approximately 10.2 m.
This solution assumes that the given sides form a right triangle. If the triangle is not a right triangle, the Pythagorean theorem may not be applicable and a different method may be needed to find the missing side.

Forces of 34 N and 46 N make an angle of 42° with each other and are applied to the same point. Find the magnitude and direction of the resultant force.
The magnitude and direction of the resultant force are respectively; F = 44.954 N and θ = 36.47°.
How to find the magnitude and resultant of two forces?We are given two forces as;
F₁ = 34 N
F₂ = 46 N
Angle between the two forces; θ = 42°
Now, the formula to find the resultant of the two forces is gotten by using the cosine rule as;
F = √[F₁² + F₂² + 2F₁F₂cos θ]
Where θ represents the angle between the two force vectors
Thus;
F = √[34² + 46² + 2(34 * 46 * cos 42]
F = 44.954 N

average speed = total distance / total time
total distance = 10.4 + 8.6 mi = 19 miles
total time = ( 181 + 227 min ) = 408 min
hence average speed = ( 10.4 + 8.6 mi) / ( ( 181 + 227 min )/60 min/hr) =2.79 mi/hr
