Answer:

15.2 cm, 130 m

Step-by-step explanation:

1. The sine of angle Z is XY/17.4; (opposite/hypotenuse);

sin(61) = XY/17.4; multiply both sides by 17.4 to find XY

17.4sin(61) = 15.2 cm

2.

This triangle is made by the anchor of the balloon to the ground, the balloon, and the area on the ground directly below the balloon.

The hypotenuse of the triangle is the 170 m string.

The angle of inclination is 50 degrees.

The height of the triangle will be opposite of the angle of inclination.

Therefore,

sin(50) = height/170 (opposite/hypotenuse)

170sin(50) = 130.2 meters

the answer would be C, lol we all don’t pay attention in class sometimes haha

Which function has the greater x-intercept Function A X, 0,2,4,6 Y, 10,8,6,4 Function B y = -2x^2 + 1

Answers

Answer:

function A

Step-by-step explanation:

First, we need to find the function of A. USing the coordinate points (0, 10) and (2,8)

Since y = mx+c

m = y2-y2/x2-x1

m = 8-10/2-0

m = -2/2

m = -1

From the coordinate (0, 10), the y-intercept is 10 i.e c = 10

The required equation is y = -x + 10

x intercept occurs at where y = 0

0 = -x+10

x =10

Hence the x-intercept of function A is 10

For Function B y = -2x^2 + 1

when y = 0

0 = -2x^2 + 1

2x^2 = 1

x^2 = 1/2

x = 1/√2

Hence the x intercept is 1/√2

Hence the function that has a greater y-intercept is function A

Explanation:

Triangle UBD is congruent to triangle RAN

Note the order of the lettering as it's important.

BD and AN are the last two letters of UBD and RAN in that order. Therefore, these sides correspond and BD = AN. From that, we know,

BD = AN

2y+5 = 3y+2

5-2 = 3y-2y

3 = 1y

y = 3

-----------

Using similar logic, UD and RN are the first and last letters of UBD and RAN respectively. So,

UD = RN

calculate the compound interest on an investment of R6500 at 7,5% per annum invested for 3 years​

Answers

Answer:

Compound interest = Rs 1,575 (Approx.)

Step-by-step explanation:

Given:

Amount invested = R.s 6,500

Rate of interest = 7.5% per annum

Number of year = 3 year

Find:

Amount of compound interest

Computation:

Compound interest = P[(1+r)ⁿ - 1]

Compound interest = 6500[(1+7.5%)³ - 1]

Compound interest = 6500[(1+0.075)³ - 1]

Compound interest = 6500[(1.075)³ - 1]

Compound interest = 6500[1.2423 - 1]

Compound interest = 6500[0.2423]

Compound interest = 1574.95

Compound interest = Rs 1,575 (Approx.)

Suma masurilor a doua unghiuri este egala cu 180(de grade). Determinati masura fiecarui unghi stiind ca unul dintre unghiuri are masura egala cu 20% din masura celuilalt unghi

Answers

Answer:

150 grados

30 grados

Step-by-step explanation:

Sea x la medida del primer ángulo

Sea la medida del segundo ángulo y

Según la pregunta;

x + y = 180 -------- (1)

De la segunda oración;

x = 0,2 años -------- (2)

Sustituyendo (2) en (1)

0,2 años + y = 180

1,2 años = 180

y = 180 / 1,2

y = 150 grados

Pero;

x = 0,2 años

Entonces

x = 0,2 (150)

x = 30 grados

Por eso;

y = 150 grados

x = 30 grados

To be in want of it, is to pass through life with little credit or pleasure; it is to live out of the world, or to be despised if you come into it; it is not to be sent for to court, or asked out to dinner, or noticed in the street; it is not to have your opinion consulted or else rejected with contempt, to have your acquirements carped at and doubted, your good things disparaged, and at last to lose the wit and the spirit to say them; it is to be scrutinized by strangers, and neglected by friends; it is to be a thrall to circumstances, an exile in one's own country; to forego leisure, freedom, ease of body and mind, to be dependent on the good-will and caprice of others, or earn a precarious and irksome livelihood by some laborious employment; it is to be compelled to stand behind a counter, or to sit at a desk in some public office, or to marry your landlady, or not the person you would wish; or to go out to the East or West Indies, or to get a situation as judge abroad, and return home with a liver-complaint; or to be a law-stationer, or a scrivener or scavenger, or newspaper reporter; or to read law and sit in court without a brief; or to be deprived of the use of your fingers by transcribing Greek manuscripts, or to be a seal-engraver and pore yourself blind; or to go upon the stage, or try some of the Fine Arts; with all your pains, anxiety, and hopes, and most probably to fail, or, if you succeed, after the exertions of years, and undergoing constant distress of mind and fortune, to be assailed on every side with envy, back-biting, and falsehood, or to be a favourite with the public for awhile, and then thrown into the backgroundor a gaol*, by the fickleness of taste and some new favourite; to be full of enthusiasm and extravagance in youth, of chagrin and disappointment in after-life; to be jostled by the rabble because you do not ride in your coach, or avoided by those who know your worth and shrink from it as a claim on their respect or their purse; to be a burden to your relations, or unable to do anything for them; to be ashamed to venture into crowds; to have cold comfort at home; to lose by degrees your confidence and any talent you might possess; to grow crabbed, morose, and querulous, dissatisfied with every one, but most so with yourself; and plagued out of your life, to look about for a place to die in, and quit the world without any one's asking after your will.
