Answer:
Note that both relations and functions have domains and ranges. The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range.

Step-by-step explanation:
The formula is given by :
[tex]s=\dfrac{m}{360}\times 2\pi r[/tex]
We have,
m = 19° and d = 9 cm
So,
[tex]s=\dfrac{19}{360}\times 2\pi \times \dfrac{9}{2}\\\\s=1.49[/tex]
Hence, this is the required soltion.

How much could you save for retirement if you chose to invest the oney you spend on Starbucks coffee in one year? Assume you buy one venti latte for $4.50 each weekday for 50 weeks and can invest the total amount in a mutual fund earning 5% compounded annually for 30 years. ROUND THE ANSWER TO TWO DECIMAL PLACES.
Amount saved for retirement: ________________
Answer:
The answer should be $7,087.50
Step-by-step explanation:
4.50 x 50 = 225
225 x 1.05 = 236.25
236.25 x 30 = 7087.50
Compound interest is the interest we earned from the principal together with the interest.
The formula for compound interest:
A = P [tex](1 + \frac{R}{n})^{nT}[/tex]
P = $1125
R = 5% compounded annually
Time = 30 years.
The amount saved for retirement is $4861.13.
What is compound interest?It is the interest we earned from the principal together with the interest.
The formula for the amount earned with compound interest after n years is given as:
The formula for compound interest:
A = P [tex](1 + \frac{R}{n})^{nT}[/tex]
We have,
Principal:
There are 5 weekdays in a week.
50 weeks = 50 x 5 weekdays = 250 weekdays.
One weekday = $4.50
250 weekdays = 250 x 4.50 = $1125
Now,
P = $1125
Rate = R = 5%
Time = T = 30 years
n = 1
The formula for compound interest:
A = P [tex](1 + \frac{R}{n})^{nT}[/tex]
A = 1125 [tex](1 + \frac{5}{100}) ^{30}[/tex]
A = 1125 x 4.321
A = 4861.125
A = $4861.13
Thus,
The amount saved for retirement is $4861.13.

Answer:460
Step-by-step explanation:on delta math
The total number of action figures in Genesis's collection will be 460.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that, Genesis offers a variety of action figures. She hangs the remainder and keeps some in a display cabinet. 253 of her action figures are hung on the wall, and the display case holds 45% of her collection.
The obtained expression for the given condition,
=253 / (1-0.45)
=253/0.55
=25300/55
=460
Thus, the total number of action figures in Genesis's collection will be 460.

Two cylinders are similar with diameters 6 in and 9 in.
a. Find the ratio of the circumference of their bases
b. Find the ratio of the surface areas.
c. Find the ratio of the volumes.
Answer:
a. Ratio of their circumference = 2:3
b. The ratio of their surface areas = 2:3
c. The ratio of their volume = 4:9
Step-by-step explanation:
Let the cylinders be labelled as A and B respectively.
Diameter of cylinder A = 6 in,
its radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{6}{2}[/tex] = 3 in
Diameter of cylinder B = 9 in,
its radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{9}{2}[/tex] = 4.5 in
Thus,
a. circumference of a circle = 2[tex]\pi[/tex]r
Circumference of cylinder A = 2[tex]\pi[/tex]r
= 2 x [tex]\pi[/tex] x 3
= 6[tex]\pi[/tex] in
Circumference of cylinder B = 2[tex]\pi[/tex]r
= 2 x [tex]\pi[/tex] x 4.5
= 9[tex]\pi[/tex]
Ratio of their circumference = [tex]\frac{circumference of cylinder A}{circumference of cylinder B}[/tex]
= [tex]\frac{6\pi }{9\pi }[/tex]
= 2:3
b. The surface area of a cylinder = 2[tex]\pi[/tex]rh
the surface area of cylinder A = 2[tex]\pi[/tex]rh
= 6[tex]\pi[/tex]h
the surface area of cylinder B = 2[tex]\pi[/tex]rh
= 9[tex]\pi[/tex]h
The ratio of their surface areas = [tex]\frac{surface area of cylinder A}{surface area of cylinder B}[/tex]
= [tex]\frac{6\pi h}{9\pi h}[/tex]
= 2:3
c. Volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h
volume of cylinder A = [tex]\pi[/tex][tex]r^{2}[/tex]h
= [tex]\pi[/tex] x [tex]3^{2}[/tex] x h
= 9[tex]\pi[/tex]h
volume of cylinder b = [tex]\pi[/tex][tex]r^{2}[/tex]h
= [tex]\pi[/tex] x [tex]4.5^{2}[/tex] x h
= 20.25[tex]\pi[/tex]h
The ratio of their volume = [tex]\frac{volume of cylinder A}{volume of cylinder B}[/tex]
= [tex]\frac{9\pi h}{20.25\pi h}[/tex]
= 4:9

If employees who make more money pay a higher percentage of their income
to the government, this is known as
A. flat taxation
B. federal income taxation
C. progressive taxation
D. regressive taxation
Answer:
C. progressive taxation
Step-by-step explanation:
Taxation can be defined as the involuntary or compulsory fees levied on individuals or business entities by the government to generate revenues used for funding public institutions and activities.
There are three (3) types of taxation used by the government, these are;
1. Regressive taxation: it involves charging individuals with low incomes a higher percentage of their total income and vice-versa.
- For instance, John pays 15% on $60,000 and Joyce pays 20% on $36,000.
2. Proportional taxation: it involves charging both lower and higher income earners equally in proportion to their income.
- For instance, John pays 20% on $50,000 and Joyce pays 20% on $36,000.
3. Progressive taxation: it involves charging individuals having higher incomes a higher percentage of their total income.
- For instance, John pays 30% on $70,000 and Joyce pays 10% on $45.000.
Hence, if employees who make more money pay a higher percentage of their income to the government, this is known as progressive taxation.

Answer:
Line segment AD
[tex]AD = \sqrt{(c-0)^{2}+(d-0)^{2}}[/tex]
[tex]AD = \sqrt{c^{2}+d^{2}}[/tex]
Line segment BC
[tex]BC = \sqrt{[(b+c)-b]^{2}+(d-0)^{2}}[/tex]
[tex]BC = \sqrt{c^{2}+d^{2}}[/tex]
Line segment AB
[tex]AB = \sqrt{(b-0)^{2}+(0-0)^{2}}[/tex]
[tex]AB = \sqrt{b^{2}+0^{2}}[/tex]
[tex]AB = b[/tex]
Line segment CD
[tex]CD = \sqrt{[c-(b+c)]^{2}+(d-d)^{2}}[/tex]
[tex]CD = \sqrt{b^{2}+0^{2}}[/tex]
[tex]CD = b[/tex]
Step-by-step explanation:
We defined the length of each side by the Equation of the Line Segment, which is a particular case of the Pythagorean Theorem. Let [tex]A(x,y) = (0,0)[/tex], [tex]B(x,y) = (b,0)[/tex], [tex]C(x,y) = (b+c, d)[/tex] and [tex]D(x,y) = (c,d)[/tex], we construct the equations below:
Line segment AD
[tex]AD = \sqrt{(c-0)^{2}+(d-0)^{2}}[/tex]
[tex]AD = \sqrt{c^{2}+d^{2}}[/tex]
Line segment BC
[tex]BC = \sqrt{[(b+c)-b]^{2}+(d-0)^{2}}[/tex]
[tex]BC = \sqrt{c^{2}+d^{2}}[/tex]
Line segment AB
[tex]AB = \sqrt{(b-0)^{2}+(0-0)^{2}}[/tex]
[tex]AB = \sqrt{b^{2}+0^{2}}[/tex]
[tex]AB = b[/tex]
Line segment CD
[tex]CD = \sqrt{[c-(b+c)]^{2}+(d-d)^{2}}[/tex]
[tex]CD = \sqrt{b^{2}+0^{2}}[/tex]
[tex]CD = b[/tex]
