Lily has two times as much money invested in 8% stocks as she has in bonds paying 6%. How much she has invested in stocks if her annual income from stocks and bonds is $325.6?

Answers

Answer:

Final answer is $4440.

Step-by-step explanation:

Let amount of money invested in 8% stock = x

Let amount of money invested in 6% stock = y

then total money invested $325.6 gives equation

8% of x + 6% of y = 325.6

0.08x + 0.06y = 325.6

8x + 6y = 32560...(i)

other equation will be x=2y...(ii)

plug (ii) into (i)

8x + 6y = 32560

8(2y) + 6y = 32560

16y+ 6y = 32560

22y = 32560

[tex]y=\frac{32560}{22}[/tex]

y=1480

plug y=1480 into (ii)

x=2y=2(1480)=2960

Then total money invested in stocks = x+y= 1480+2960=4440

Hence final answer is $4440.

Find the area of the yellow region.
Round to the nearest tenth.

Answers

Answer:

5.4 ft²

Step-by-step explanation:

Since the circle is inscribed in the square then radius r = 2.5

Area of yellow = area of square - area of circle

A = (5 × 5) - (π × 2.5²)

  = 25 - 6.25π ≈ 5.4 ft²

               

Answer:

Area of the Yellow Region is 5.4 ft²

Step-by-step explanation:

Given:

Length of the side of the square = 5 ft

Diameter of the Circle = Length of the side = 5 ft

⇒ Radius of the circle, r = 5/2 = 2.5 ft

To find: Area of the Yellow region from the figure.

Area of the Yellow Region = Area of the Square - Area of the Circle

                                            = Side × Side - πr²

                                            = 5 × 5 - 3.14 × (2.5)²

                                            = 25 - 3.14 × 6.25

                                            = 25 - 19.625

                                            = 5.375

                                            ≈ 5.4 ft²   (nearest tenth)

Therefore, Area of the Yellow Region is 5.4 ft²

simplify sin x / CSC x + cos x / sec x​

Answers

Final answer:

The expression sin x / csc x + cos x / sec x simplifies to sin^2 x + cos^2 x by using the reciprocal identities of the trigonometric functions csc x and sec x.

Explanation:

The expression sin x / csc x + cos x / sec x can be simplified by substituting the reciprocal identities for the trigonometric functions csc x and sec x. The reciprocal of csc x is sin x and the reciprocal of sec x is cos x. Thus, sin x / csc x becomes sin x / (1/sin x) which simplifies to sin^2 x. Similarly, cos x / sec x becomes cos x / (1/cos x) or cos^2 x. Therefore, the simplified form of the expression is sin^2 x + cos^2 x.

Use complete sentences to describe the domain of the cosine function

Answers

The domain of a function is the complete set of possible values of the independent variable.

The cosine function is represented by the expression: y=cos(x), where "x" is the independent function, and "y" the dependent function. So the domain comes to be all the values that "x" can take.

The domain of the cosine function is all the real numbers. All this can be verified by looking at its graph (attached)

---------- = cot B = ----------------------- =  ---------

 tan B                   opposite side            AC

Answer:

Hence, The reciprocal of tan B is tan A

B is correct.

Step-by-step explanation:

We are given a right angle triangle. Right angle at ∠C

We need to find the reciprocal of tan B

First we write the formula of tan B using trigonometry identity.

[tex]\tan\theta=\dfrac{\text{Opposite}}{\text{Base}}[/tex]

In ΔABC, ∠C=90°

[tex]\tan B=\dfrac{AC}{BC}[/tex]

Now we reciprocal it.

[tex]\dfrac{1}{\tan B}=\dfrac{BC}{AC}[/tex]

[tex]\tan A=\dfrac{BC}{AC}[/tex]

Comparing both equation ( Right sides equal )

[tex]\dfrac{1}{\tan B}=\dfrac{BC}{AC}=\tan A[/tex]

[tex]\dfrac{1}{\tan B}=\tan A[/tex]

Hence, The reciprocal of tan B is tan A.

C. $3724.80

D. $9724.80​

Answers

Answer:

The total interest paid by Nell in 20 years is $3,724.80

C is correct

Step-by-step explanation:

Nell took out a subsidized student loan of $6000 at a 4.8% APR, compounded  monthly.

First we find total amount in 10 months

[tex]A=6000(1+\frac{0.048}{12})^{10}[/tex]

[tex]A=6244.37[/tex]

Now, He has to pay loan off on 6244.37 for 20 years at 4.8% APR

Loan Formula:

[tex]P=\dfrac{PV\cdot r}{1-(1+r)^{-n}}[/tex]

PV=6244.37

r=0.048/12

n=240

[tex]P=\dfrac{6244.37\times \frac{0.048}{12}}{1-(1+\frac{0.048}{12})^{-240}}[/tex]

[tex]P=40.52[/tex]

Total pay in 20 years = 40.52 x 20 = 9724.80

Total amount took loan = $6000

Interest = 9724.80 - 6000

             = $3,724.80

Hence, The total interest paid by Nell in 20 years is $3,724.80

Zoologists are studying two newly discovered species of insects in a previously unexplored section of rain forest. They estimate the current population of insect A to be 1.3 million and the current population of insect B to be 2.1 million. As development is encroaching on the section of rain forest where these insects live, the zoologists estimate the populations of insect A to be reducing at a rate of 3.8% and insect B to be reducing at a rate of 4.6%.

[tex]P = 1.3e ^ {-0.038t}\\\\P = 2.1e ^ {-0.046t}[/tex]

Step-by-step explanation:

The equation for exponential decay has the following form:

[tex]y = pe ^{-rt}[/tex]

Where

p is the initial population  

r is the rate of decrease

t is time.

In this problem we have to:

The current population of insect A to be 1.3 million and the current population of insect B to be 2.1 million.

So

[tex]p_1 = 1.3[/tex]  in millions

[tex]p_2 = 2.1[/tex]  in millions

We also need the populations of insect to be reduced at a rate of 3.8% and insect to be reduced at a rate of 4.6%.

so:

[tex]r_1 = 0.038\\\\r_2 = 0.046[/tex]

then the exponential decay equation for insect A is:

[tex]P = 1.3e ^ {-0.038t}[/tex]

the exponential decay equation for insect B is:

[tex]P = 2.1e ^ {-0.046t}[/tex]

Finally, the system of equations is:

[tex]P = 1.3e ^ {-0.038t}\\\\P = 2.1e ^ {-0.046t}[/tex]

Suppose you need to choose a new combination for your combination lock. You have to choose 3 numbers, each different and between 0 and 40. How many combinations are there? Explain

Answers

Answer:

63,960 possibilities in total.

Step-by-step explanation:

For the first number, you can choose from 41 different numbers, so there are 41 possibilities.

For the second number, you cannot choose the same as the first one, so you are now limited to 40 possibilities.

For the third number, you are down to 39 possibilities since you cannot pick the same as the first two ones.

So, you have 41 * 40 * 39 = 63,960 possibilities in total.

Picking a new combination is easy... remembering it is the hard part :-)

If you want to calculate it from a formula standpoint, the base formula would be:

[tex]P(n,r) = \frac{n!}{(n-r)!} = \frac{41!}{(41-3)!} = 63960[/tex]

Where n is the total numbers possible and r is the quantity of numbers you have to pick.

line p has an x-intercept of 5 and a y-intercept of 3. Find the slope of line p

Answers

Answer:

Step-by-step explanation:

you can use the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope of a line when given two points.

we are given both the x and y intercepts, and we can use those in the formula.

the x intercept is (5,0) and the y intercept is (0,3)

i will treat (5,0) as my x1 and y1, and (0,3) as my x2 and y2

[tex]\frac{3-0}{0-5}[/tex] = -3/5

the slope is -3/5

The slope of the line is -3/5 if the line p has an x-intercept of 5 and a y-intercept of 3.

What is a straight line?

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have a line p:

The x-intercept of line p is 5 or (5, 0)

The y-intercept of line p is 3 or (0, 3)

The slope m can be evaluated:

[tex]\rm m =\dfrac{3-0}{0-5}[/tex]

m = -3/5

Thus, the slope of the line is -3/5 if the line p has an x-intercept of 5 and a y-intercept of 3.

Myself, I saw my aunt's misshapened figure with that feeling of awe and respect with which we behold explorers who have left their ears and fingers north of Franz Josef Land, or their health somewhere along the Upper Congo. My Aunt Georgiana had been a music teacher at the Boston Conservatory, somewhere back in the latter sixties. One summer, while visiting in the little village among the Green Mountains where her ancestors had dwelt for generations, she had kindled the callow fancy of the most idle and shiftless of all the village lads, and had conceived for this Howard Carpenter one of those extravagant passions which a handsome country boy of twenty-one sometimes inspires in an angular, spectacled woman of thirty. When she returned to her duties in Boston, Howard followed her, and the upshot of this inexplicable infatuation was that she eloped with him, eluding the reproaches of her family and the criticisms of her friends by going with him to the Nebraska frontier. Carpenter, who, of course, had no money, had taken a homestead in Red Willow County, fifty miles from the railroad. There they had measured off their quarter section themselves by driving across the prairie in a wagon, to the wheel of which they had tied a red cotton handkerchief, and counting off its revolutions. They built a dugout in the red hillside, one of those cave dwellings whose inmates so often reverted to primitive conditions. Their water they got from the lagoons where the buffalo drank, and their slender stock of provisions was always at the mercy of bands of roving Indians. For thirty years my aunt had not been further than fifty miles from the homestead.2 But Mrs. Springer knew nothing of all this, and must have been considerably shocked at what was left of my kinswoman. Beneath the soiled linen duster which, on her arrival, was the most conspicuous feature of her costume, she wore a black stuff dress, whose ornamentation showed that she had surrendered herself unquestioningly into the hands of a country dressmaker. My poor aunt's figure, however, would have presented astonishing difficulties to any dressmaker. Originally stooped, her shoulders were now almost bent together over her sunken chest. She wore no stays, and her gown, which trailed unevenly behind, rose in a sort of peak over her abdomen. She wore ill-fitting false teeth, and her skin was yellow from constant exposure to a pitiless wind and to the alkaline water which hardens the most transparent cuticle into a sort of flexible leather.3 I owed to this woman most of the good that ever came my way in my boyhood, and had a reverential affection for her. During the years when I was riding herd for my uncle, my aunt, after cooking the three mealsthe first of which was ready at six o'clock in the morningand putting the six children to bed, would often stand until midnight at her ironing board, with me at the kitchen table beside her, hearing me recite Latin declensions and conjugations, gently shaking me when my drowsy head sank down over a page of irregular verbs. It was to her, at her ironing or mending, that I read my first Shakespeare; and her old textbook on mythology was the first that ever came into my empty hands. She taught me my scales and exercises, tooon the little parlor organ, which her husband had bought her after fifteen years, during which she had not so much as seen any instrument, but an accordion that belonged to one of the Norwegian farmhands. She would sit beside me by the hour, darning and counting while I struggled with the "Joyous Farmer," but she seldom talked to me about music, and I understood why. She was a pious woman; she had the consolations of religion and, to her at least, her martyrdom was not wholly sordid. Once when I had been doggedly beating out some easy passages from an old score of Euryanthe I had found among her music books, she came up to me and, putting her hands over my eyes, gently drew my head back upon her shoulder, saying tremulously, "Don't love it so well, Clark, or it may be taken from you.
