Two sectors of a circle of radius $12$ overlap as shown, with $P$ and $R$ as the centers of the respective circles. Determine the area of the shaded region.
The area of the shaded region is 26.088 sq units.
A circle is a particular type of ellipse in mathematics or geometry where the eccentricity is zero and the two foci are congruent. A circle is also known as the location of points that are evenly spaced out from the center.
The radius of a circle is measured from the center to the edge. The line that splits a circle into two identical halves is its diameter, which is also twice as wide as its radius.
Area of a 60-degree sector of a circle with radius 12 = 60/360 pi 12^2 Since, there are two of these minus the area of equilateral triangle = sqrt3 /4 12^2 = 60/360 pi 12^2 * 2 - sqrt3 /4 12^2 *2 = 26.088 sq units
Thus, the area of the shaded region is 26.088 sq units.

How does the parabola open? Is the vertex a minimum or maximum value?
f(x) = 5x²-3x
The parabola is open upward direction. The vertex is the minimum value of the parabola.
What is a parabola?
A parabola is a planar curve that is mirror-symmetrical and roughly U-shaped in mathematics. It fits various seemingly disparate mathematical descriptions, all of which can be shown to define the same curves. A point and a line are two ways to describe a parabola.
Given quadratic function is
f(x) = 5x² -3x
The leading term of the given function is 5x².
The sign of the leading term is positive, thus it is open upward direction.
Rewrite the given function in the form f(x) = a(x - h)² + k
f(x) = 5x² -3x
f(x) = 5( x² - 3/5 x)
f(x) = 5( x² - 3/5 x + 9/100 - 9/100)
f(x) = 5( x² - 3/5 x + 9/100) - 5 × 9/100
f(x) = 5( x - 3/10)² - 9/20
f(x) = 5( x - 3/10)² + (-9/20)
The vertex of the parabola is (3/10, -9/20).
Since the parabola opens upward direction, thus the vertex of the parabole is a minimum value.

(a) Express tanθ in terms of secθ for θ in Quadrant II (b) Express secθ in terms of sinθ for θ in Quadrant III
a. The trigonometric ratio tanθ = -√(sec²θ - 1)
b. The trigonometric ratio secθ = -1/√(1 - sin²θ)
What are trigonometric ratios?Trigonometric ratios are the following mathematical expressions sinθ, cosθ, tanθ,secθ,cosecθ and cotθ.
a. How to express tanθ in terms of secθ for θ in Quadrant II?Since we want to express tanθ in terms of secθ in the second quadrant,using the trigonometric identity
tan²θ + 1 = sec²θ
Making tanθ subject of the formula, we have that
tan²θ = sec²θ - 1
tanθ = ±√(sec²θ - 1)
Since in Quadrant II, tanθ is negative, we choose the negative answer.
So, tanθ = -√(sec²θ - 1)
b. How to express secθ in terms of sinθ for θ in Quadrant II?Since we want to express tanθ in terms of secθ in the second quadrant,using the trigonometric identity
secθ = 1/cosθ and
sin²θ + cos²θ = 1
Making cosθ subject of the formula, we have that
cos²θ = 1 - sin²θ
cosθ = ±√(1 - sin²θ)
So, secθ = 1/cosθ
= ±1/√(1 - sin²θ)
Since in Quadrant III, secθ is positive, we choose the positive answer.
So, secθ = -1/√(1 - sin²θ)

Charles and wilma have diffrent internet providers. Charles pays $0. 25 per gigabyte of data. Wilma pays a flat fee of $20 and $0. 05 per gigabyte How many gigabytes of data must each use for charles internet bill to be equal to wilma's interet bill
100 terabytes of data must be used in order for Charles' internet bill to equal Wilma's internet cost.
What is the Intercept of the equations?Assume that there are x gigabytes of data.
The equation for Charles is y = 0.25x since he pays $0.25 for each gigabyte of data.
The calculation for Wilma is y = 0.05x + 20 because she pays a flat rate of $20 and $0.05 per gigabyte.
Charles must pay the same amount for internet service as Wilma, so;
0.25x = 0.05x + 20
0.2x = 20
x = 20/0.2
x = 100
Hence, 100 terabytes of data must be used in order for Charles' internet bill to equal Wilma's internet cost.

I’m doing math homework and is about functions they said f(x)= x-3 and g(x)= √x-2
After I set them up I have this
am I supposed to just add the numbers or is there something else to do?
√ (x-3)-2
Answer: It looks like you are trying to find the value of the function h(x) = √ (x-3) - 2.
To find the value of this function for a given value of x, you need to substitute the value of x into the function definition and simplify the expression.
For example, if you want to find the value of h(x) for x = 5, you would substitute 5 for x in the function definition and simplify the expression to get:
h(5) = √(5-3) - 2
= √2 - 2
= 1.4 - 2
= -0.6
Therefore, the value of h(x) for x = 5 is -0.6.
You can follow this same process to find the value of h(x) for any other value of x. Just be sure to substitute the correct value of x into the function definition and simplify the expression to find the final result.
Step-by-step explanation:
Answer:
g[f(x)]
Step-by-step explanation:
Given functions:
[tex]f(x)=x-3[/tex]
[tex]g(x)=\sqrt{x}-2[/tex]
Composite functions are when the output of one function is used as the input of another.
Therefore, to create √(x-3)-2, substitute the function f(x) in place of the x in function g(x):
[tex]\begin{aligned}\implies g[f(x)]&=\sqrt{f(x)}-2\\&=\sqrt{x-3}-2\end{aligned}[/tex]

How does graph y=-3(x+1)2 -1 transforms from the parent function y=x^2?
Given:
The function is:
[tex]y=-3(x+1)^2-1[/tex]
The parent function is:
[tex]y=x^2[/tex]
To find:
The transformation of the given function from the parent function.
Solution:
The transformation of a function is given by:
[tex]g(x)=kf(x+a)+b[/tex] .... (i)
Where, k is stretch factor, a is horizontal shift and b is vertical shift.
If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k.
If k<0, then the graph of f(x) is reflected across the x-axis.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
The given function can be written as is:
[tex]g(x)=-3(x+1)^2-1[/tex]
Let the parent function be [tex]f(x)=x^2[/tex], then
[tex]g(x)=-3f(x+1)-1[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]k=-3,a=1,b=-1[/tex]
Therefore, the graph of parent function is stretched vertically by by factor 3 and reflected across the x-axis because [tex]k=-3[/tex], after that the graph of the function shifts 1 unit left and 1 unit down to get the graph of given function.

Which of the following is not a descriptor of a normal distribution of a random variable? A. The graph of the distribution is symmetric B. The graph is centered around zero C. The graph of the distribution is bell-shaped. D. The graph is centered around the mean
A normal distribution of a random variable cannot be described (D) by a graph that is centered on the mean.
What is a normal distribution?A continuous probability distribution for a real-valued random variable in statistics is known as a normal distribution or Gaussian distribution.
Since all three of these variables are equal in a normal distribution, they serve as the center of the graph and can either be zero or not.
An example of a continuous probability distribution is the normal distribution, in which the majority of data points cluster in the middle of the range while the remaining ones taper off symmetrically toward either extreme.
The distribution's mean is another name for the center of the range.
Therefore, a normal distribution of a random variable cannot be described (D) by a graph that is centered on the mean.

Write the equation of a line that is perpendicular to y=14x - 4 and passes through the point (28, 16)
Write a linear function for the values given in the table below
A function whose equation is of the form y = ax + b, where a and b are constants, a does not equal zero, and x is any real number, and whose graph is a straight line.
Given an equation y = 14x -4 there is an equation that is perpendicular to this given equation.
from the slope-intercept of a linear equation:
The linear function equation is the slope-intercept form. Thus, it is expressed as f(x) = mx + b where m is the slope and b is the y-intercept of the line.
thus the slope of the given equation is 14
The slope of the required equation = 1/14
Since both equations are perpendicular
From the slope intercept of the required line equation of a line:
y = 1/14x + c...(2)
Since, it passes through the point (28, 16)
Thus, 16 = 1/14 *28 + c
c = 16
from equation 2
y = 1/14 x + 14
from the table, two given coordinates of a linear function are (4, 36) and (6, 56)
thus slope of the line = (y₂ - y₁) / (x₂ - x₁)
Slope of the line = 20/2 = 10
Equation of a line:
y = 10x +c
Since, it passes through the point (4, 36)
Thus, 36 = 40 + c
c = -4

Step-by-step explanation:
The first side of the given triangle = 6 units
The second side of the given triangle = 6 units
The third side of the given triangle = 9 units
In an isosceles triangle, two sides of a triangle are equal and if sides are equal they have the same angle at the base.
The given triangle is an isosceles triangle.
What do you call the angle measures 90 180 and 270?
An angle that measures 90 degrees is called a right angle, an angle that measures 180 degrees is called a straight angle and an angle that measures 270 degrees is called a reflex angle.
A right angle is an angle that measures exactly 90 degrees. It is formed by the intersection of two lines that are perpendicular to each other. A right angle is symbolized by a small square at the vertex of the angle.
A straight angle is an angle that measures exactly 180 degrees. It is formed by the intersection of two lines that are collinear, that is, they lie on the same line. A straight angle is represented by a straight line, usually with an arrow on one end pointing in the direction of the other end.
A reflex angle is an angle that measures greater than 180 degrees but less than 360 degrees. It is formed by the intersection of two lines that are not collinear, that is, they don't lie on the same line and the angle is greater than a straight angle. A reflex angle is represented by an arc with a curved arrow on one end, pointing in the direction of the other end.
