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°

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°

Yes; the triangles are congruent by SAS.

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.

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

So, the dimensions are 70.5 by 72.5

Answer: $118.75

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.

A) The inverse of f(x) is f⁻¹(x) = (x² + 9)/3 and B) f is not an inverse of g.

First to be an inverse function that function needs to one to one function, meaning every different preimage must correspond to a different image.

We can obtain the inverse of a function by switching the variables x and y with their respective positions and solving for y in terms of x.

Given, f(x) = [tex]\sqrt{3x - 9}[/tex].

y = [tex]\sqrt{3x - 9}[/tex].

y² = 3x - 9.

3x = y² + 9.

x = (y² + 9)/3.

y = (x² + 9)/3.

f⁻¹(x) = (x² + 9)/3 and g(x) = 3x² - 9, so f is not an inverse of g.

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.

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.

One of the triangle's centers where the bisectors of the inner angles converge is known as the incline. The incenter is often referred to as the incircle's center in a triangle. An incenter might have several distinct types of characteristics.

The junction point of the central axis, which is the center of the triangle's inscribed circle, places this point at an equal distance from each of the triangle's sides. Since the biggest circle that might fit within a triangle is the incenter, it is also referred to as the center of the triangle's circle.

The probability is the first and the second case will be 0.625 and 0.3683, respectively.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

A pack contains five white balls and three torpedoes. You want to draw two white balls.

Total events = 5 + 3

Total events = 8

You all the while drawing two balls aimlessly. Then the probability that they are both white is given as,

P = 5 / 8

P = 0.625

You all the while drawing two balls aimlessly. Whenever you have drawn two balls, you set back any debases, and redraw with the goal that you again have two drawn balls. Then the probability is given as,

P = [(3/8) x (5/8)] + [(3/8) x (5/8) x (4/7)]

P = (15 / 64) + (60 / 448)

P = 0.3683

The equation of the given function is y = -1/3 x. By using the points through which the line passing through, we can find its equation. Option A is correct.

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)

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)

⇒ y - 1 = -1/3 (x + 3)

⇒ 3y - 3 = -x - 3

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.
