Consider the following equation

3x + 9y = 8y - 2

Step 2 of 2: Find the equation of the line which passes through the point (13,5) and is perpendicular to the given line. Express your answer in
slope-intercept form. Simplify your answer.

Answers

Answer:

The perpendicular line is:

y = 1/3 x + 2/3

Step-by-step explanation:

The given equation can be reduced to its slope-intercept form as shown below:

3x + 9y = 8y - 2

subtract 8 y from both sides

3 x + y = -2

subtract 3 x from both sides

y = - 3 x -2

therefore we know that the slope of this line is -3, and then, a perpendicular line to it must have slope given by the "opposite of the reciprocal" of this slope. That is, the slope of any perpendicular line to this one must be: 1/3

We use this slope to find the equation of the line passing through the point (13. 5)

y = 1/3 x + b

passing through (13, 5) means:

5 = 1/3 (13) + b

therefore, we can find b from the above equation

b = 5 - 13/3 = 15/3 - 13/3 = 2/3

Then the equation of this perpendicular line is:

y = 1/3 x + 2/3

Find sin D and sin E. Write each answer as a fraction and as a decimal. Round to four decimals places.

Answers

Answer/Step-by-step explanation:

✔️Sin D = opp/hyp

Opp = 12

Hyp = 15

Sin D = 12/15 = 4/5 (as fraction )

Sin D = 0.8 (as decimal)

✔️Sin E = opp/hyp

Opp = 9

Hyp = 15

Sin E = 9/15 = 3/5 (as fraction)

Answers

Answer:

0.812 = 81.2% probability that a randomly chosen chip will pass the test

Step-by-step explanation:

Over the long run, the fraction of bad chips produced by the process is 20%.

So 100 - 20 = 80% are good.

All good chips pass the test, while 6% of the bad chips(20%) also pass.

a) (4 points) What is the probability that a randomly chosen chip will pass the test

[tex]p = 0.8 + 0.06*0.2 = 0.812[/tex]

What kind of math is this?

2m+(m-15)=90 solve for m

Answers

Answer:

m = 35

Step-by-step explanation:

2m + m -15 = 90

3m -15 = 90

+15 +15

3m = 105

/3 /3

m = 35

To check the work just insert 35 for m:

of one leg equal to 9 centimeters and
the length of the hypotenuse equal to
15 centimeters, what is the length of
the other leg?
F 6 cm
H square root of 306 cm
G 12 cm
J 144 cm

Answers

Answer:

G. 12 cm

Step-by-step explanation:

Length of one leg of right triangle = a = 9 cm

Length of hypotenuse = c = 15 cm

Length of the other leg = b = ?

Applying pythagorean theorem, c² = a² + b², we have:

15² = 9² + b²

15² - 9² = b²

144 = b²

b = √144

b = 12

What is the equation of a line?

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

From the graph, the coordinate points are (1, 2.5) and (2.5, 3.5)

Here, slope m=(3.5-2.5)/(2.5-1)

= 1/1.5

= 0.67

Substitute m=0.67 and (x, y)=(1, 2.5) in y=mx+c, we get

2.5=0.67+c

c=1.83

Substitute m=0.67 and c=1.83 in y=mx+c, we get

y=0.67x+1.83

Therefore, the function represent the given graph is f(x)=0.67x+1.83.

TrueB. False If, as the world has long agreed, a very great amount of instruction will not make a wise man, still less will a very mediocre amount of instruction make a wise woman. And the most mischievous form of feminine silliness is the literary form, because it tends to confirm the popular prejudice against the more solid education of women.When men see girls wasting their time in consultations about bonnets and ball dresses, and in giggling or sentimental love-confidences, or middle-aged women mismanaging their children, and solacing themselves with acrid gossip, they can hardly help saying, For Heavens sake, let girls be better educated; let them have some better objects of thoughtsome more solid occupations. But after a few hours conversation with an oracular1 literary woman, or a few hours reading of her books, they are likely enough to say, After all, when a woman gets some knowledge, see what use she makes of it! Her knowledge remains acquisition instead of passing into culture; instead of being subdued into modesty and simplicity by a larger acquaintance with thought and fact, she has a feverish consciousness of her attainments; she keeps a sort of mental pocket-mirror, and is continually looking in it at her own intellectuality; she spoils the taste of ones muffin by questions of metaphysics; puts down men at a dinner-table with her superior information; and seizes the opportunity of a soire2 to catechise3 us on the vital question of the relation between mind and matter. And then, look at her writings! She mistakes vagueness for depth, bombast for eloquence, and affectation for originality; she struts on one page, rolls her eyes on another, grimaces in a third, and is hysterical in a fourth. She may have read many writings of great men, and a few writings of great women; but she is as unable to discern the difference between her own style and theirs as a Yorkshireman is to discern the difference between his own English and a Londoners: rhodomontade4 is the native accent of her intellect. Nothe average nature of women is too shallow and feeble a soil to bear much tillage;5 it is only fit for the very lightest crops.It is true that the men who come to such a decision on such very superficial and imperfect observation may not be among the wisest in the world; but we have not now to contest their opinionwe are only pointing out how it is unconsciously encouraged by many women who have volunteered themselves as representatives of the feminine intellect. We do not believe that a man was ever strengthened in such an opinion by associating with a woman of true culture, whose mind had absorbed her knowledge instead of being absorbed by it. A really cultured woman, like a really cultured man, is all the simpler and the less obtrusive for her knowledge; it has made her see herself and her opinions in something like just proportions; she does not make it a pedestal from which she flatters herself that she commands a complete view of men and things, but makes it a point of observation from which to form a right estimate of herself. She neither spouts poetry nor quotes Cicero6 on slight provocation; not because she thinks that a sacrifice must be made to the prejudices of men, but because that mode of exhibiting her memory and Latinity7 does not present itself to her as edifying or graceful. She does not write books to confound philosophers, perhaps because she is able to write books that delight them. In conversation she is the least formidable of women, because she understands you, without wanting to make you aware that you cant understand her. She does not give you information, which is the raw material of cultureshe gives you sympathy, which is its subtlest essence.The author writes approvingly of the cultured womans restraint in quoting poetry and Latin authors (paragraph 3, sentence 4) becausethe author respects the womans desire to conform to received notions of feminine modestyAthe author endorses the womans decision to tolerate male prejudices against educated womenBit shows the womans ambition to produce original work instead of parroting the works of canonical authorsCit reveals the womans thoughtful consideration of the effects of her own behavior on othersDit suggests that the woman has wisely devoted more time to studying modern languages than to studying classical literatureE Anyone knows this one What is the intercept of y=-1/2x-1 and y=1/4x-4 Lane is fourteen years older than Michelle.
