Answer 1

Answer:  

9 diagonals  

Bit by bit clarification:  

Number of Diagonals = n(n-3)/2  

For instance, in a hexagon, the complete sides are 6.

Along these lines, the complete diagonals will be 6(6-3)/2 = 9.

Does this represent a proportional relationship? Explain your answer. A specific shade of orange paint calls for 2 parts yellow and 3 parts red. Catie uses 3 cups of yellow paint and 4 cups of red paint to make orange paint.

Answers

Answer:

proportional relationship is not represented by them

Step-by-step explanation:

Ratio a/b and c/d are said to be proportional if a/b = c/d.

_________________________________________________

ratio of yellow part and red part for specific shade of orange =

2 part yellow/ 3 parts red = 2/3

____________________________________________________

ratio of yellow part and red part used by Catie =

3 cups of  yellow/ 4 cups of   red = 3/4

we have two ratio 2/3 and 3/4

but 2/3 is not equal to 3/4

To cover a distance of 240km, a car has to increase the speed by 5km/hr to reach in time. If the time lost was 40 minutes during traffic jam, find the original speed of the car.

Answers

Answer:

Step-by-step explanation:

Given That

To cover a distance of 240km, a car has to increase the speed by 5km/hr to reach in time. If the time lost was 40 minutes during traffic jam, find the original speed of the car.

                                  .

increased speed of car = 5km/hr .....(speed 1st)

distance travelled = 240km

speed = distance travelled / time taken

= 240 / 40

= 6

thus,

speed = 6km/hr .....(speed 2nd)

.

therefore original speed

= speed 2nd - speed 1st

= 6-5

= 1

Ans. thus, the original speed of the car is 1km/hr.

Answers

Answer:

25 percent

Step-by-step explanation:

Total months: 12

Months read more than three books: 3

3/12=25 percent

Answer:

1/4 = 25%.

Step-by-step explanation:

To figure out the percent of months in which she read more than 3 books, we need to figure out how many times she read more than 3 books.

According to the table, she read more than 3 books exactly 3 times: 4, 5, 5.

We also know that there is a total of 12 months. Out of the 12 total months, she read more than 3 books 3 times. So we can say that:

3/12 = 1/4 = 25% of the months she read more than 3 books.

Answers

Answer:

see below

Step-by-step explanation:

The total number of trees is

567+324+156+89+678 =1814

Percent fir = 567/1814 = .312568908=31.26 %

Percent pine = 324/1814 = .178610805=17.86%

Percent larch = 156/1814 =.085997795=8.60%

percent cedar = 89/1814 =.049062845=4.91%

Percent hemlock = 678/1814 = .373759647=37.38%

The total should be 100 %

31.26+17.86+8.60+4.91+37.38=100.01  ( rounding error because we rounded to the hundredths place)

Answer:

15A.)

1814 total trees

15B.)

Fir: 31.256890849%

Pine: 17.861080485%

Larch: 8.599779492%

Cedar: 4.906284454%

Hemlock: 37.375964718%

Step-by-step explanation:

15A.) For this first part, you would add all the trees together to get the total:

567+324+156+89+678 = ?

891+156+89+678 - Add 567 and 324 together.

1047+89+678 - Add 891 and 156 together.

1136+678 - Add 1136 and 678 together.

=1814 total trees

15B.) For this second part, you would divide each tree type (567, 324, 156, 89, 678) by the total trees (1814). To convert the decimal to a percent, you would move the decimal point to places to the right. Not sure how many decimal places you wanted for each percent, so I gave the full decimal for you to round as you please on your answer.

Fir: 567/1814 = 0.31256890849 = 31.256890849%

Pine: 324/1814 = 0.17861080485 = 17.861080485%

Larch: 156/1814 = 0.08599779492 = 8.599779492%

Cedar: 89/1814 = 0.04906284454 = 4.906284454%

Hemlock: 678/1814 = 0.37375964718 = 37.375964718%

Test whether the following functions are analytic exp(x).(cos y + i sin y)

Answers

Answer:

The given f(z) is analytic function

i)  δU/δx   = eˣ (cos y) = δV/δy    

ii)  δU/δy   = eˣ (-sin y) = -  δV/δx  

Hence the CR - equations are satisfied

Step-by-step explanation:

Explanation:-

Analytic function:-

A point at which an analytic function ceases to posses a derivative is

called a singular point of the function.Thus the necessary and sufficient condition for a complex function f(Z) = U+i V is analytic in a region R are

δU/δx = δV/δy     and δU/δy = -δV/δx    ( C R equations)

Given f(Z) = eˣ(cos y+ i sin y)

Let          U = eˣ(cos y)   ....(i)

and

              V = eˣ(sin y) ....(ii)

Differentiating equation(i) partially with respective to 'x'

             δU/δx   = eˣ (cos y)

Differentiating partially equation(i) with respective to 'y'

             δU/δy    = eˣ (-sin y)

Differentiating equation(ii) partially with respective to 'x'

             δV/δx    = eˣ (sin y)

Differentiating equation(ii) partially with respective to 'y'

             δV/δy    = eˣ (cos y)

Now

          δU/δx   = eˣ (cos y) = δV/δy    

i)            δU/δx = δV/δy  

           δU/δy   = eˣ (-sin y) = -  δV/δx    

ii)         δU/δy = -  δV/δx    

Hence the CR - equations are satisfied

Allison plays basketball and last season she made a total of 87 shots (two- or three- point shots). Her points total was 191. How many three-points shots did she make

Answers

Answer:

Step-by-step explanation:

Let the number of 2 point shots be t.

Let the number of 3 point shots be h.

Allison made 87 shots and scored 191 total points. This implies two things:

t + h = 87 ________(1)

2t + 3h = 191 ______(2)

Let us eliminate t by multiplying (1) by 2 and subtracting from (2):

=> 2t + 3h = 191

 -  2t + 2h = 174

               h  = 17

Therefore, she made 17 three point shots.

Answer:

Step-by-step explanation:

We have the amount she will pay back, but first, we need to find the Interest accrued.

Simple Interest is given as:

[tex]I = \frac{P * R * T }{100}[/tex]

where P = principal

R = rate

T = time taken (in years)

Therefore, the interest on $3,000 at 9%  simple interest for 4 years is:

[tex]I = \frac{3000 * 9 * 4}{100}[/tex]

I = $1080

Therefore, the amount she will pay back is:

Multiplication is the process of determining the product of two or more numbers in mathematics. A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics.

The product is always negative when a negative integer is multiplied by a positive number. The result is always positive whether you multiply two negative or positive numbers.

What are trigonometric relations?

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the distance between the maximum of a sine or cosine graph be A

Now , the maximum of sine graph is when θ = 90°

So , sin 90° = 1

The sine function ranges between -1 and 1, so the minimum is -1 and the maximum is 1

And , the maximum of cos graph is when θ = 360°

So , cos 360° = 1

Maximum value of cos θ is 1 when θ = 0˚, 360˚. Minimum value of cos θ is –1 when θ = 180 ˚.

Hence , amplitude represents half the distance between the maximum of a sine or cosine graph
