A . Increase in Gilbert’s average biking speed

B. Distance Gilbert’s travels

C . Time it takes Gilbert’s to travel 5 miles

D . Biking speed for the second practice ride .

Answers

Answer 1

Answer:

D . Biking speed for the second practice ride

Add

Step-by-step explanation:

Given :

First practice ride:

Distance = 5 miles

2nd practice ride :

Distance = 9 miles

Time models for each practice ride ;

First practice ride :

a(x) = 5 / x

x = speed

2nd practice ride :

b(x) = 9 / (x + 2)

Recall :

Time taken: distance / speed ; compacting with time taken equation of the 2nd practice ride :

Hence,

Speed of 2nd practice ride = x + 2

B.) To obtain a function for the total amount of time :

We take the sum of the first and second practice time : a(x) + b(x)

5/x + 9/(x+2)

Answer 2

The weights of 1000 onions from a certain farm follow a normal distribution with a mean of 150 g and a standard deviation 15 g from the data we can conclude that about blank onions way more than 165 g in about blank onions way less than 135 g

Answers

Answer:

About 159 weigh more than 165 g and about 159 g weigh less Than 135 g

Step-by-step explanation:

Given that :

Mean, μ = 150

Standard deviation, σ = 15

Using the Zscore formula :

Zscore = (x - μ) / σ

For x > 165

P(x > 165)

Z = (165 - 150) / 15

Z = 15 /15 = 1

P(Z > 1) = 0.15866 (Z probability calculator)

1000 * 0.15866 = 158.66 = 159

For x < 135

P(x < 135)

Z = (135 - 150) / 15

Z = - 15 /15 = - 1

P(Z > - 1) = 0.15866 (Z probability calculator)

1000 * 0.15866 = 158.66 = 159

The total population of Aiken County is 173,000 and there are approximately 23,000 students enrolled in Aiken County schools. What percentage of Aiken County residents are enrolled in Aiken County schools? Round your answer to the nearest tenth.

Answers

Answer:

Percentage = 13%

Step-by-step explanation:

Given the following data;

Total population = 173,000

Number of students = 23,000

To find the percentage;

[tex] Percentage = \frac {Number \; of \; students}{Total \; population} * 100 [/tex]

[tex] Percentage = \frac {23,000}{173,000} * 100 [/tex]

[tex] Percentage = \frac {23}{173} * 100 [/tex]

[tex] Percentage = 0.1330 * 100 [/tex]

Percentage = 13.3 ≈ 13%

Therefore, the percentage of Aiken County residents that are enrolled in Aiken County schools is 13%.

PMI (Private Mortgage Insurance) protects the lender in case the borrower cannot make the loan payments. It is often required when the amount of the loan is close to the value of the home. PMI typically annually costs about .75% of the entire loan. On a $100,000 loan what would you be paying per month?

Answers

Answer:

$62.50

Step-by-step explanation:

The amount of private mortgage insurance required in this case per annum is 0.75% of the entire loan which is $100,000.

Annual insurance=0.75%*loan amount

Annual insurance=0.75%*$100,000

Annual insurance=$750

Since the annual cost of mortgage insurance per year is established, monthly cost would be annual cost divided by 12 months is which is number of months in a year that payments are to be made

monthly payment=$750/12

monthly payment=$62.50

Law of cosines:

In trigonometry, the Cosine Rule says that the square of the length of any side of a given triangle is equal to the sum of the squares of the length of the other sides minus twice the product of the other two sides multiplied by the cosine of angle included between them.

[tex]c^{2} = a^{2} + b^{2} - 2ab cos(C)[/tex]

Since we have two side lengths and an angle, we can use the Law of Cosines to find the length of the final side.

In this case we can write the law of cosines as,

[tex]f^{2} = d^{2} + e^{2} - 2(de)cos(F)[/tex]

f2 = 5.22 + 6.82 - 2(5.2)(6.8)cos(166)

f2 = 27.04 + 46.24 - 66.56 cos (166)

f2 = 73.28 - 66.56 cos 166

f = √(73.28 - 66.56 cos 166) ≈ 11.9 ft.

f ≈ 11.9 ft.

how to integrate [tex]e^{2s} *Cos \frac{s}{4}[/tex] , please help, I have no idea what to do, I would appreciate if you show your work with steps.

Answers

Answer:

[tex]\int\limits {e^{2s} cos\frac{s}{4} ds[/tex]    =[tex]\frac{4 e^{2s} }{65 } ({8 cos (\frac{1}{4} ) s + sin \frac{1}{4} s} ))[/tex]

Step-by-step explanation:

Step(i):-

Given that  [tex]f(s) = e^{2s} cos\frac{s}{4}[/tex]

Now integrating

            [tex]\int\limits {f(s)} \, ds = \int\limits {e^{2s} cos\frac{s}{4} ds[/tex]

By using integration formula

   [tex]\int\limits { e^{ax} cos b x dx = \frac{e^{ax} }{a^{2}+b^{2} } ( a cos b x + b sin b x )[/tex]

Step(ii):-

 [tex]\int\limits {e^{2s} cos\frac{s}{4} ds[/tex]    =   [tex]\frac{e^{2s} }{(2)^{2}+(\frac{1}{4}) ^{2} } ( 2 cos (\frac{1}{4} ) s + \frac{1}{4} sin \frac{1}{4} s ))[/tex]  

                    = [tex]\frac{e^{2s} }{(4+\frac{1}{16})} ( 2 cos (\frac{1}{4} ) s + \frac{1}{4} sin \frac{1}{4} s ))[/tex]

                   = [tex]\frac{e^{2s} }{(\frac{65}{16} } ( \frac{8 cos (\frac{1}{4} ) s + sin \frac{1}{4} s}{4} ))[/tex]

                 = [tex]16 X\frac{e^{2s} }{65 } ( \frac{8 cos (\frac{1}{4} ) s + sin \frac{1}{4} s}{4} ))[/tex]

                 =[tex]\frac{4 e^{2s} }{65 } ({8 cos (\frac{1}{4} ) s + sin \frac{1}{4} s} ))[/tex]

Final answer:-

[tex]\int\limits {e^{2s} cos\frac{s}{4} ds[/tex]    =[tex]\frac{4 e^{2s} }{65 } ({8 cos (\frac{1}{4} ) s + sin \frac{1}{4} s} ))[/tex]
