_________________________________________________

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

2 part yellow/ 3 parts red = 2/3

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

Amelia stars reading at 3: 25 and reads for 15 minute. What type of angle is formed by the hour and minute hands of the clock wen Amelia fineshes reading

Answers

Answer:

Step-by-step explanation:

If sh starts reading at 3:25 and reads for 15 minutes, she is finished at 3:40. The hour hand is on the 3 and the minute hand is on the 8, so there is a difference of 25 minutes between the hour hand and the minute hand. Each 5-minute increment is 30 degrees (360 / 12) so 30 x 5 = 150 degrees. This is an obtuse angle. Not sure what kind of an answer you're looking for so I gave both the degree measure of the angle formed by the hour hand and the minute hand, and the classification of the angle.

Answer:

90 degrees, which is a right angle

Step-by-step explanation:

The time indicates when she starts reading is irrelevant. The only thing to notice is that she reeds for 15 minutes. Whenever you read for 15 minutes the angle that is formed by the hour and minute hands of the clock will always be the same, regardless of the starting time!

60 minutes comes down to 360 degrees.

1 minute = 60/60 and that comes down to 360/60 = 6 degrees.

15 minutes = 15 times 1 minute....

15 minutes comes down to 15* 6 = 90 degrees

90 degrees is a right angle

To buy a computer, Raquel borrowed $3,000 at 9%

simple interest for 4 years. How much money did she

have to pay back? (Hint: Combine both the principal and

simple interest for money she has to pay back).

Answers

Answer:

$4080

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:

$3000 + $1080 = $4080

Step-by-step explanation:

The total number of trees is

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:

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%

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

There fore the given f(z) is analytic function

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.
