A movie is not a real image, it is a series of still images or frames that are played back in rapid succession to create the illusion of motion.
Real images are those that are formed by light that has been refracted or reflected by an object or lens. These images are located on the same side of the lens as the object and can be projected onto a screen or viewed directly.
In movie, the images are typically captured on film or digitally and then played back on a screen at a high frame rate (usually 24 or 30 frames per second) to create the illusion of motion.
This is known as the persistence of vision effect. The images are not actually moving, but the human eye and brain perceive them as moving because of the rapid succession of still images.
In conclusion, a movie is not a real image, it is a series of still images played back in rapid succession to create the illusion of motion.
Real images are formed by light that has been refracted or reflected by an object or lens, whereas in movie the images are captured on film or digitally and then played back on a screen at a high frame rate to create the illusion of motion.

A baker has 85 cups (c) of flour to make bread she uses 6 1/4 c of flour for each loaf of bread.
Now, The fraction 6 1/4 can be written as 25/4.
Therefore, The number of bread loaf the baker can make is,
= (85/25/4).
= 85×(4/25).
= (17×4)/5.
= 68/5.

Which trigonometric ratios are correct for triangle abc? select three options. Sin(c) = cos(b) = tan(c) = sin(b) = tan(b) =.
The correct ratios are
sin(C) = [tex]\frac{\sqrt{3} }{2}[/tex] , tan(C) =[tex]\sqrt{3}[/tex] , sin(B) = [tex]\frac{1}{2}[/tex]
Consider the below figure attached to this question.
In triangle ABC, ∠A=90°, ∠B=30° and ∠C=60°, AC=9 and BC=18.
Using Pythagoras' theorem we get
hypotenuse² = perpendicular² + base²
BC² = AB² + AC²
⇒(18)² = AB² + 9²
⇒324 - 81 = AB²
Taking square root on both sides.
⇒√243 = AB
∴ √3 =AB
Trigonometric ratios are
[tex]sin(C) = \frac{opposite}{hypotenuse} = \frac{AB}{BC} = \frac{9\sqrt{3} }{18} =\frac{\sqrt{3} }{2}[/tex]
[tex]cos(B) = \frac{base}{hypotenuse} = \frac{AB}{BC} = \frac{9\sqrt{3} }{18} =\frac{\sqrt{3} }{2}[/tex]
[tex]tan(C) = \frac{opposite}{basee} = \frac{AB}{AC} = \frac{9\sqrt{3} }{9} =\sqrt{3}[/tex]
[tex]sin(B) = \frac{opposite}{hypotenuse} = \frac{AC}{BC} = \frac{9 }{18} =\frac{1}{2}[/tex]
[tex]tan(B) = \frac{opposite}{base} = \frac{AC}{AB} = \frac{9 }{9\sqrt{3} } =\frac{1 }{\sqrt{3} }[/tex]
Therefore, the correct ratios are
sin(C) = [tex]\frac{\sqrt{3} }{2}[/tex] , tan(C) = [tex]\sqrt{3}[/tex] , sin(B) =[tex]\frac{1}{2}[/tex]

how to solve 3x+5<14
Answer:
x<3
Step-by-step explanation:
3x+5<14
Your first step is to simplify the inequality.
To do this, always look to see if you can subtract any numbers from both sides to isolate a variable.
You can subtract 5 from both sides to isolate the 3x on one side.
After that, you will get 3x<9
Next, you must divide both sides by 3 to try and get x by itself, completing the inequality.
9/3 = 3
Your are left with: x<3
Done!
Answer:
x < 3
Step-by-step explanation:
3x + 5 < 14 subtract 5 from both sides
3x + 5 - 5 < 14 - 5
3x < 9 Divide both sides by 3
[tex]\frac{3x}{3}[/tex] < [tex]\frac{9}{3}[/tex]

How do you find the height of an obtuse angle?
To find the height of an obtuse angle in a triangle, you can use the following steps:
Identify the obtuse angle in the triangle.Draw the altitude from the vertex of the obtuse angle to the hypotenuse.The altitude forms a right triangle with the hypotenuse as the base and the altitude as the height of the obtuse angle.Use the Pythagorean theorem to find the length of the altitude. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.It is important to note that the hypotenuse of the right triangle (the base) must be the side opposite to the obtuse angle, and the other two sides should be the legs of the triangle. Also, the altitude can fall inside or outside of the triangle, it does not affect the calculation of the height.

All the angles from the polygon path made by the students are;
∠1 = 96°
∠2 = 90°
∠3 = 162°
∠4 = 132°
∠5 = 60°
How up illustrate the polygon?The images of the polygon are missing and so i have attached them. From the attached image, we can see we have;
Triangle (3-sided polygon)
Square (4-sided polygon)
Pentagon (5-sided polygon)
Hexagon (6 sided polygon)
Now, we know that formula for external angle of a polygon with n sides is 360/n.
Thus, for the 6-sided polygon, the ∠5 = 360/6
∠5 = 60°
Since ∠4 is shared by the pentagon and hexagon, then;
∠4 = (360/5) + 60
∠4 = 72° + 60°
∠4 = 132°
Since ∠3 is shared by the square and pentagon, then;
∠3 = 90 + 72
∠3 = 162°
∠2 = 90° because external angles of a square = 360/4 = 90°

The perimeter of a shape is the sum of the distance along its sides. For a rectangle:
Perimeter = 2(length + width)
Let L represent the length and W represent the width of a rectangle with a perimeter of 88 feet
If the length of the rectangle is 3 times its width, hence:
L = 3W
Perimeter = 2(L + W)

What are the 3 notations for domain and range?
Set-builder notation: {x | x ∈ D} (where D is the domain) and {y | y ∈ R} (where R is the range), Interval notation: (a, b) (where a and b are the minimum and maximum of the domain) and [c, d] (where c and d are the minimum and maximum of the range) , Graphical notation: The domain and range are represented by a graph.
Set-builder notation is a way of representing the domain and range of a function. It uses curly brackets surrounding the domain and range variables, separated by a vertical bar. The form is {x | x ∈ D} (where D is the domain) and {y | y ∈ R} (where R is the range). This notation is useful when the domain and range are not easily written as a set of numbers.
Interval notation is another way of representing the domain and range of a function. It uses parentheses to represent the domain and square brackets to represent the range. The form is (a, b) (where a and b are the minimum and maximum of the domain) and [c, d] (where c and d are the minimum and maximum of the range). This notation is useful when the domain and range are quickly written as a set of numbers.
Graphical notation is a third way of representing the domain and range of a function. In this case, the domain and range are represented by a graph, with the x-axis representing the domain and the y-axis representing the range. This notation is useful when visualizing the relationship between the domain and range of a function.

Rachel has 0.41 quarters that can be obtained using the equation Q + D + N = T.
We can start by using the following equation to find the number of quarters Rachel has: Q + D + N = T
Where Q is the number of quarters, D is the number of dimes, N is the number of nickels, and T is the total amount of money in dollars. We know that T is $4.65, and we know that Rachel has twice as many nickels as quarters, and three more quarters than dimes.
Let's assume that Rachel has x number of quarters
So we can write the above equation as:
x + (x+3) + 2x = 4.65
4x+3 = 4.65
4x = 1.65
x = 0.4125
Rachel has 0.4125 quarters, Which is not possible as it is a decimal. So we need to round it off to the nearest whole number.
Rachel has 0.4125 quarters which is equivalent to o.41 quarters.
