Answer:
a) The rotational speed of the clay: 3.45 rad/s.
b) The value of A in the equation of motion: 0.15 m.
c) The value of ϕi: 90° or π/2 rad.
Given that;
Revolution per minute( rpm) is = 33( 1/3) = 100/3
The frequency ( f) is= 100 / 3(60) = 0.55 Hz
a) Rotational speed W = 2πf
we substitute
W = 2π × 0.55
W = 3.45 rad/s
So, the rotational speed of the clay is 3.45 rad/s.
b) given equation; y(t)=Asin(ωt+ϕi)
given that radius = 0.15 m
y(t)=(0.2)sin(ωt+ϕi)
So, the value of A in the equation of motion is 0.15 m.
c) since y(t) has the maximum value at t =0
so at t=0
y(0) = (0.15)sin(ω(0)+ϕi)
= 0.15sin(ϕi)
this gives maximum value when ϕi = 90°
so,
y(0) = (0.15)sin(ω(0)+ϕi)
= 0.15sin(90°)
= 0.15
So, the value of ϕi is 90° or π/2 rad.

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.

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.

The minimum and maximum possible volume for a rectangular right prism are 1221.875 and 1603.125 cubic inches.
What are the minimum and maximum possible volume of a rectangular prism?
In this problem we must determine the minimum possible and maximum possible volumes for a rectangular right prism, whose volume formula including length uncertainties is shown below:
V = (w ± Δw) · (l ± Δl) · (h ± Δh)
Where:
w - Width, in inches.l - Length, in inches.h - Height, in inches. Δw - Width uncertainty, in inches.Δl - Length uncertainty, in inches.Δh - Height uncertainty, in inches.Please notice that minimum possible volume is found when all "±" operators are replaced by "-" operators and that maximum possible volume is found when all "±" are replace by "+" operators. Given that statement does not mention the value of every length uncertainty, we assume that Δw = Δl = Δh = 0.5 in.
If we know that w = 12 in, l = 13 in, h = 9 in and Δw = Δl = Δh = 0.5 in, then the minimum and maximum possible volumes are:
Minimum possible volume
V = (12 in - 0.5 in) · (13 in - 0.5 in) · (9 in - 0.5 in)
V = (11.5 in) · (12.5 in) · (8.5 in)
V = 1221.875 in³
Maximum possible volume
V = (12 in + 0.5 in) · (13 in + 0.5 in) · (9 in + 0.5 in)
V = (12.5 in) · (13.5 in) · (9.5 in)

600=5+60 what was the annual interrest rate
On solving the provided question, annual rate is 2% while doing calculations through simple interest.
What is simple interest?Borrowers must pay simple interest to lenders as a fee for a loan. Compound interest is not taken into account while calculating it; just the principal is used. Simple interest is applicable to all loans. It is also the form of interest that banks give their customers on their savings accounts. Simple interest can be calculated using a simple formula. Simply multiply the loan's principal by the interest rate and the period to get the total. Although some mortgages employ this calculation approach, this type of interest typically relates to auto loans or short-term loans.
Let the annual rate be x%
Principal Amount (p)= $600
Annual Rate (r) = x % (Assumed)
Time (t) = 5 years
Simple Interest (I) = $60
Use the simple interest formula given below:
SI = p×r×t/100
r = 60 ×100/600× 5
r = 2%

It is best to use the substitution method when equations are either given in form or can be gain into the form of x = ay + b and y = mx + n.
A procedure to answer a system of linear equations in more than two variables algebraically is the substitution method. In this process, we find the value of any one of the variables by alienating it on one side and taking every other term on the other side of the equation.
Then we substitute that first value in the second equation.
The substitution method is one of the algebraic processes to answer simultaneous linear equations. It implies substituting the value of any one of the variables from one equation into the other equation.

The first step of Sam's proof is to show that logb(MN) is equal to logb(b^x.b^y), which is a substitution of MN for b^x.b^y. This is based on the product property of logarithms, which states that logb(MN) = logb(M) + logb(N) for any positive numbers M and N and any base b, as long as b doesn't equal 1.
The third step of her proof is to simplify logb(b^x.b^y) further by applying the power rule of exponents, which states that:
b^(x+y) = b^x.b^ySo, by substituting b^(x+y) for b^x.b^y, we get:
logb(b^(x+y)) = logb(b^x+y)So, in short, the justification of the third step is based on the power rule of exponents, and it shows that logb(b^x.b^y) can be simplified further to logb(b^x+y).
The answer choice A, logb(b^xy), power rule of exponents, is incorrect because it implies that the third step is to multiply x and y instead of adding them.
This question should be provided with answer choices, which are:
A. logb(b^xy), power rule of exponents.B. logb(b^x-y), subtraction property of exponents.C. logb(b^x+y), power rule of exponents.D. logb(b^x/y), division property of exponents.The correct answer is C.

the diameter of the circle is 5.35, what is the area?
The area of the circle, considering it's diameter of 5.35, is given as follows:
22.48 units squared.
What is the area of a circle?The area of a circle of radius r is given by π multiplied by the radius squared, as follows:
A = πr²
The diameter for the circle in this problem is given as follows:
5.35.
The radius is half the diameter, hence it's length is given as follows:
r = 0.5 x 5.35
r = 2.675.
Hence the area of the circle is given as follows:
A = π x (2.675)²
A = 22.48 units squared.
