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

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

The straight-line distance between the points is ___ units, rounded to the nearest tenth.
Answer:
The straight-line distance between the points is approximately 8.6.
Step-by-step explanation:
The straight-line distance ([tex]d[/tex]) between the points is determined by the following Pythagorean identity:
[tex]d = \sqrt{x^{2}+y^{2}}[/tex] (1)
Where:
[tex]x[/tex] - Horizontal distance between the points.
[tex]y[/tex] - Vertical distance between the points.
Let consider that each square has a distance of 1 unit. If we know that [tex]x = 5[/tex] and [tex]y = -7[/tex], then the straight-line distance is:
[tex]d = \sqrt{5^{2}+(-7)^{2}}[/tex]
[tex]d \approx 8.6[/tex]
The straight-line distance between the points is approximately 8.6.
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.

A farmer claims that the average mass of an apple grown in his orchard is 100g. To test this claim, he measures the mass of 150 apples that are grown in his orchard and determines the average mass per apple to be 98g. The results are calculated to be statistically significant at the 0.01 level. What is the correct interpretation of this calculation?
A. The data are not statistically significant at the 0.05 level.
B. The mean mass of any 150 apples grown in the farmer's orchard is 98g.
C. At the 0.01 level of significance, the mean mass of the apples grown in the farmer's orchard is different from 100g.
D. At the 0.01 level of significance, the mean mass of the apples grown in the farmer's orchard is 98g.
Answer:
C. At the 0.01 level of significance, the mean mass of the apples grown in the farmer's orchard is different from 100g.
Step-by-step explanation:
The null hypothesis is:
[tex]H_{0} = 100[/tex]
Because of the claim of the farmer.
The alternate hypothesis is:
[tex]H_{1} \neq 100[/tex]
The alternate hypothesis tests the farmer's claim at a significance level.
The results are calculated to be statistically significant at the 0.01 level.
This means that at the 0.01 level, the null hypothesis is rejected, that is, the mean mass of the farmer's orchard is different from 100. Since it is significant at the 0.01 level, it will be significant at the 0.05, 0.1, and increasing levels. So the correct answer is given by option C.

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.
