Arc QR =
Arc RS =
Applying the inscribed angle theorem, the measures of the angles and arcs in the image given are:
Arc QR = 48°
Arc RS = 96°
Arc QPS = 216°
Arc PSR = 186°
Arc SRQ = 144°
What is the Inscribed Angle Theorem?The inscribed angle theorem state that the measure of an intercepted arc is equal to twice the measure of the inscribed angle.
Find arc PSR:
Arc PSR = 2(93) [based on the inscribed angle theorem]
Arc PSR = 186°
Find arc QR:
Arc QR = 360 - arc PQ - arc PSR
Substitute
Arc QR = 360 - 126 - 186
Arc QR = 48°
The value of ARC QR is 48
Arc RS = arc PSR - arc PS
Arc RS = 186 - 90
Arc RS = 96°
The value of ARC RS is 96
Arc QPS = 126 + 90
Arc QPS = 216°
Arc PSR = arc PS + arc RS
Arc PSR = 90 + 96
Arc PSR = 186°
Arc SRQ = arc RS + arc QR
Arc SRQ = 96 + 48
Arc SRQ = 144°
Therefore the value of ARC QR is 48° and ARC RS is 96°

The disadvantage of piece rate pay is that the cost of producing higher quantities of a product can be a reduction in the quality of the items produced.
What is piece rate?Piece rate is any type of job in which a worker is paid a set amount for each unit produced or action performed, regardless of time. Some employees may be paid on a piece rate or on a commission basis.
Employees are paid on a piece rate, and commission payments are based on results rather than an hourly or weekly pay rate. This means that the employee's weekly pay will vary depending on how much work they do. One of the drawbacks of piece rate pay is that the cost of producing larger quantities of a product may result in a decrease in the quality of the items produced.

What is triangle ?
A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.
A triangle is a 3-sided polygon that is occasionally (though not frequently) referred to as the trigon. There are three sides and three angles in every triangle, some of which may be the same.
AC and BD bisects one another
AE = CE --- Side
and
BE = DE --- Side
When both lines bisect one another, they form a pair of vertical angles and
When we apply the theorem of vertical angles to this, we have that:
∠AEB = ∠CED --- Angle
At this point, we have established:
Two sides of ABE and CDE are congruent and One angle in each of ABE and CDE are also congruent
Hence, the triangles are congruent by SAS.

how do i find the inverse of f(x)=[tex]\sqrt[3]{5x+5}[/tex]
The inverse of f(x) = ∛5x + 5 is f⁻¹ = ( x³ - 5 ) / 5
What is inverse of function?
To find the inverse of a function, write the function y as a function of x i.e. y = f(x) and then solve for x as a function of y.An inverse function is a function that undoes the action of the another function. A function g is the inverse of a function f if whenever y=f(x) then x=g(y).Change y in for the f(x) :
y = ∛5x + 5
Switch the x and y
x³ = 5y + 5
x³ - 5 = 5y
y = ( x³ - 5 ) / 5
f⁻¹ = ( x³ - 5 ) / 5
Hence, The inverse of f(x) = ∛5x + 5 is f⁻¹ = ( x³ - 5 ) / 5

The length and width of two sides of a rectangle are consecutive odd integers. The area of the rectangle is 143 square units.
Find the dimensions of the rectangle.
The width of the rectangle is blank and length is blank
The dimensions of the rectangle are 70.5 by 72.5 units.
What is a dimension?
A length measurement that only goes one way. Dimensions include things like width, depth, and height. One dimension is that of a line, two dimensions are found in a square, three dimensions are found in a cube, and one dimension is that of something's height, length, or width. For instance, the room is 26 feet by 15 feet in size.
Solution Explained:
Given,
Area = 143 unit^2
A/Q,
Let length be x and width be x + 2.
So, Area = l X w
143 = x + x + 2
143 = 2x + 2
x = (143 - 2)/2
x = 70.5
So width = x + 2 = 70.5 + 2 = 72.5

HURRY HELP ME! A group of workers is harvesting berries at a constant rate. The following equation represents the total number of baskets of berries the workers picked over a period of time, in hours y = 10x + 5.
What are the slope and the y-intercept for the equation?
X represents the hours, what does y represent and measure in the context of this situation?
What are the rate of change and the initial amount? Explain the meaning of the rate of change and the initial amount in the context of the situation.
Use graph below to draw a graph for the equation y=10x+5. Label the axes appropriately for the situation.
Step-by-step explanation:
The equation y=10x+5 is in the y=mx+b format, where m is the slope and b is the y-intercept.
The slope is 10 and the y-intercept is 5.
Since x represent the number of hours picking berries, y would represent the total number of berries picked.
Y-intercept (or the initial amount) is 5, and slope (aka rate of change) is 10.
y=10x+5 replace x to 1 so it means that one hour has passed
y=10(1)+5 simplify
y=10+5
y=15 y represents the total number of berries picked
That means 15 berries would be picked in one hour.

What is the formula for finding the equation of a line passing through two points?The equation of the line passing through two points such as (x1, y1) and (x2, y2) is
y - y1 = [(y2 - y1)/(x2 - x1)] × (x - x1)
Calculation:From the given graph, the line is passing through the points (0, 0), (-3, 1), and (3, -1).
The equation of the line passing through (-3, 1) and (3, -1) is
y - y1 = [(y2 - y1)/(x2 - x1)] × (x - x1)
⇒ y - 1 = (-1 - 1)/(3 + 3) × (x + 3)
⇒ y - 1 = -2/6 (x + 3)

What is Cubic equation?
Cubic equations are polynomials of degree3. That means the maximum degree of polynomial is three.
And the standard form of cubic equation is;
f(x) = ax³ + bx² +cx +d, where a, b, c and d are constant coefficients a ≠ 0.
Given that the expression
f(x) = 2x³ + 4x² - 8x - 16
Now we find the roots or zeroes of equation;
for that we will try hit and trial method,
let x = 2
f(x) = 2 (8) - 4 (4) - 8(2) -16
f(x) = 0
That means (x-2) is one of roots of cubic equation.
Now to find other roots of the cubic equation, we will simplify the cubic expression
f(x) = 2x² (x-2) + 8x (x-2) + 8 (x-2)
f(x) = (x-2) (2x²+ 8x + 8)
Now we will find the roots of quadratic equation (2x²+ 8x + 8).
let g(x) = (2x²+ 8x + 8).
factors of quadratic equation is (x+2) and (x+2).
Therefore the zeroes of the expression f(x) = 2x³ + 4x² - 8x - 16 are (x-2), (x+2) and (x+2). And multiplicity of x = -2 is 2.

Step-by-step explanation: first to see how much one bracelet is, you have to do 71.25/15=4.75. one bracelet is $4.75. so now we multiply 4.75 by 25 to see how much 25 bracelets cost. 4.75x25=118.75. so, if Karen seems all of her bracelets, she can expect to make $118.75.
