Answer:Percentage of students who prefer scary movies =35%
Step-by-step explanation:
Number of students who prefer scary movies= 35
Number of students who love comedies= 65
Total number of students = 65 +35= 100
Percentage of students who prefer scary movies = Number students who prefer scary movies/ total number of students x 100
35/ 100 x 100
0.35 x 100= 35%
Which one of the following is a zero of the polynomial 3x³ 4x² 7?
The zero of the polynomial 3x³ 4x² 7 is -7/3.
In order to find the zeros of a polynomial, one must first factor the equation and then set it equal to zero. The zeros of a polynomial are the values of x that make the equation equal to zero. The zeros of a polynomial can be found by factoring the polynomial and then solving for x, which will produce the x values that make the equation equal to zero.
The zero of the polynomial 3x³ 4x² 7 is -7/3. This can be calculated by setting the polynomial equal to 0 and solving for x.
3x³ 4x² 7 = 0
3x³ 4x² = -7
3x(x² - 4) = -7
x(x² - 4) = -7/3
x² - 4 = -7/3
x² = -7/3 + 4
x² = 1/3
x = ±√(1/3)
x = ±(1/√3)
x = -7/3
Therefore, the zero of the polynomial 3x³ 4x² 7 is -7/3.

A particle moves along the x-axis with position function x ( t ) = 4 sin ( (π − t) / 2 ) for 0 ≤ t ≤ 4 π where t is measured in seconds. For what values of t does the particle have an acceleration of 0?
When t = π and t = 3π, the acceleration of a particle moving along the x axis with position function x ( t ) = 4 sin ( (π − t) / 2 ) for 0 ≤ t ≤ 4 π where t is measured in seconds is zero.
An acceleration of 0 means that the velocity of the particle is constant, so the derivative of the velocity function is 0. Therefore, the particle has an acceleration of 0 when the second derivative of the position function is 0.
The position function is
x(t) = 4 sin((π − t) / 2)
so the velocity function is
x'(t) = -2cos((π − t) / 2)
and the acceleration function is
x''(t) = - sin((π − t) / 2).
To find when x''(t) = 0, we set -sin((π − t) / 2) = 0 and solve for t:
- sin((π − t) / 2) = 0
sin((π − t) / 2) = 0
(π − t) / 2 = nπ, where n is an integer
t = π - 2nπ
So the particle has an acceleration of 0 when t = π - 2nπ, where n is an integer.
As t is in the interval 0 ≤ t ≤ 4π, the possible values of t is π and 3π.

How do you find the coordinates of two points given an equation?
To find the coordinates of two points given an equation, you can substitute different values of x into the equation and solve for y, or by using the symmetry property of the equation.
The first method to find the coordinates of two points is to substitute different values of x into the equation and solve for y. Once you have the coordinates of the two points, you can use them to graph the equation and further analyze the function.
For example, if the equation is y = 2x + 1, you can substitute x = 0 and x = 1 into the equation to find the coordinates of the two points. Substituting x = 0 gives y = 2(0) + 1 = 1, so the first point is (0,1). Substituting x = 1 gives y = 2(1) + 1 = 3, so the second point is (1,3).
Another way to find the coordinates of two points is by using the symmetry property of the equation. For example, if the equation is y = -x^2 + 4x -3, you can substitute x = -1 and x = 1 into the equation and solve for y.
In conclusion, finding the coordinates of two points given an equation involves substituting different values of x into the equation and solving for y, or by using the symmetry property of the equation.
The coordinates of the two points will be used to graph the equation and further analyze the function.

Here is another algebra math problem that I need help with, sorry I've been struggling in math. The math problem is in the picture below:
Answer: All Real Numbers Except "-8" (R - {-8})
Step-by-step explanation:
The domain of a function is all possible x values that the function can be defined with.
This means that if a value does not create any indeterminate situation, we can consider this value is in the domain of a function.
For this function, "-8" is not in the domain of the function because the denominator of a rational fraction cannot be zero in any case. This creates an indeterminate situation, therefore we do not consider "-8" in the domain of the function.
But for the other values, there is no problem since the denominator cannot be zero without x = -8.
Name an angle bisector
Down Below
Step-by-step explanation:Angle bisector
An angle bisector is a line segment, ray, or line that divides an angle into two congruent adjacent angles.
Line segment OC bisects angle AOB above. So, ∠AOC = ∠BOC which means ∠AOC and ∠BOC are congruent angles.
Bisecting an angle with compass and ruler
In geometry, it is possible to bisect an angle using only a compass and ruler. To do so, use the following steps:
Place the point of the compass on vertex, O, and draw an arc of a circle such that the arc intersects both sides of the angle at points D and E, as shown in the above figure.Draw two separate arcs of equal radius using both points D and E as centers. Make sure the radius is long enough so the arcs of the two circles can intersect at point F.Use a ruler to draw a straight ray from O to F. OF bisects the angle AOB.Things to know about an angle bisector
If a point lies anywhere on an angle bisector, it is equidistant from the 2 sides of the bisected angle; this will be referred to as the equidistance theorem of angle bisectors, or equidistance theorem, for short.
In the figure above, point D lies on bisector BD of angle ABC. The distance from point D to the 2 sides forming angle ABC are equal. So, DC and DA have equal measures.
Conversely, if a point on a line or ray that divides an angle is equidistant from the sides of the angle, the line or ray must be an angle bisector for the angle.
Based on the equidistance theorem, it can be seen that when the two sides that make up an angle are tangent to a circle, the line segment or ray formed by the angle's vertex and the circle's center is the angle's bisector.
In the diagram above, the two sides of the angle are tangent to the circle and, DC and DA are the distances from the center of the circle to the sides. DC and DA are also the radii of the circle. Since all radii of a circle have equal measure, line BD bisects the angle.
Angle bisector theorem
For a triangle, like the one in the diagram below, if the bisector of angle A intersects side BC at point D, the ratio of the lengths of AB to AC equals the ratio of the length BD to DC. This can be written as: [tex]\frac{AB}{AC}=\frac{BD}{DC}[/tex]
The point at which the three interior angle bisectors intersect is known as the incenter of the triangle. Referencing the diagram below, the three bisecting rays intersect at point D. Point D is the incenter of the triangle and is a point that is equidistant from the three sides of the triangle.

What is the least common denominator of the rational expressions below? 1/2x^2+8x + 10/x^2
The least common denominator of the given rational expressions is 2x^3(x + 4). This is the smallest expression that both denominators can be multiplied by to obtain equivalent fractions with a common denominator.
To find the least common denominator (LCD) of the rational expressions 1/(2x^2 + 8x)and 10/x^2, we need to determine the common factors in the denominators and then multiply them.
The first denominator, 2x^2 + 8x, can be factored as 2x(x + 4), where x + 4 is a linear factor.
The second denominator,[tex]x^2[/tex], is already in its factored form.
To find the LCD, we need to consider all the factors and their highest powers. In this case, we have:
2x(x + 4) and [tex]x^2[/tex]
Since the highest power of x in 2x(x + 4) is 1 and in [tex]x^2[/tex] is 2, the LCD must include both factors with their highest powers. Therefore, the LCD is:
LCD = 2x(x + 4)(x^2)
Simplifying further, we can write the LCD as:
LCD = 2x^3(x + 4)
So, the least common denominator of the given rational expressions is 2x^3(x + 4). This is the smallest expression that both denominators can be multiplied by to obtain equivalent fractions with a common denominator.
Using the LCD, we can then add or subtract the rational expressions by multiplying each term by the necessary factors to achieve the common denominator.

Answer:
∠ CEA = 95°
Step-by-step explanation:
the chord- chord angle CEA is half the sum of the measures of the arcs intercepted by the angle and its vertical angle.
∠ CEA = [tex]\frac{1}{2}[/tex] (CA + DB) = [tex]\frac{1}{2}[/tex] (148 + 42)° = [tex]\frac{1}{2}[/tex] × 190° = 95°
