if dy/dx = x(y-1), find the equation of the tangent line at x=-2 with f(-2)=3

Answers

Answer:

The equation of the tangent line passing through the point (-2,3) is

4 x + y +5 =0

Step-by-step explanation:

Step(i):-

Given that the slope of the tangent

[tex]m = \frac{dy}{dx} = x(y-1)[/tex]

m = -2( 3-1) = -4

Given point x = -2

y = f(-2) =3

∴The given point ( x₁ , y₁) = ( -2 ,3)

Step(ii):-

The equation of the tangent line passing through the point (-2,3)

[tex]y - y_{1} = m(x-x_{1} )[/tex]

[tex]y -3 = -4(x-(-2))[/tex]

y -3 = -4( x+2)

y-3 = -4x -8

4x + y -3+8=0

4x +y +5=0

Step(iii):-

The equation of the tangent line passing through the point (-2,3) is

4 x + y +5 =0

What’s measure angle K ?

Answers

Answer:

angle K = 180 - 128 = 52 degrees

Step-by-step explanation:

The sum of all angles in a triangle will always add up to 180°. So, because the two triangles are identical, you can do 180-46-82, and get your answer, which is 52°. Have a nice day!

-4x+5 + -13x+39=180 angle measure

Answers

Step-by-step explanation:

−4x+5−13x+39=180

Step 1: Simplify both sides of the equation.

−4x+5−13x+39=180

−4x+5+−13x+39=180

(−4x+−13x)+(5+39)=180(Combine Like Terms)

−17x+44=180

Step 2: Subtract 44 from both sides.

−17x+44−44=180−44

−17x=136

Step 3: Divide both sides by -17.−17x

What is the perimeter of rectangle ABCDABCDA, B, C, D?

units

Answers

The perimeter of the rectangle is 8 units

The coordinates of the rectangle is given as:

[tex]A = (-6,-4)[/tex]

[tex]B = (-4,-4)[/tex]

[tex]C = (-4,-2)[/tex]

[tex]D = (-6,-2)[/tex]

Start by calculating the distance between the vertices using the following distance formula

[tex]d=\sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]

So, we have:

[tex]AB=\sqrt{(-6 --4)^2 + (-4 --4)^2}[/tex]

[tex]AB=\sqrt{4}[/tex]

[tex]AB=2[/tex]

[tex]BC=\sqrt{(-4 --4)^2 + (-4 --2)^2}[/tex]

[tex]BC=\sqrt{4}[/tex]

[tex]BC=2[/tex]

[tex]CD=\sqrt{(-4 --6)^2 + (-2 --2)^2}[/tex]

[tex]CD=\sqrt{4}[/tex]

[tex]CD=2[/tex]

[tex]DA=\sqrt{(-6 --6)^2 + (-2 --4)^2}[/tex]

[tex]DA=\sqrt{4}[/tex]

[tex]DA = 2[/tex]

So, the perimeter of the rectangle is:

[tex]P =AB + BC + CD + DA[/tex]

This gives

[tex]P= 2 + 2+2+2[/tex]

[tex]P= 8[/tex]

Hence, the perimeter of the rectangle is 8 units

Write your answers in simplest form. what is the answerHelp me please Directions: Read the passage, and answer the question that follows.The Black DeathA The growing cities of the Middle Ages could be exciting places. However, many were dark, unsafe, and unhealthy. Streets were narrow, crooked, and filthy. There were no streetlights or police. Many people did not go out alone at night for fear of robbers. If people did go out, they often took servants along with them for protection and to carry lanterns or torches to light the way. Waste was dumped into open gutters. All in all, conditions were disgusting. This caused diseases to spread quickly through the crowded cities.B Beginning in 1347, one such disease, a terrible plague, swept through Europe. The disease was called the Black Death because of the darkened color of its victims faces after they died. The plague began in Asia and spread along busy trade routes. Trading ships carried the disease west to the Mediterranean. From the Mediterranean ports, the disease spread throughout most of Europe. Rats on the ships carried the disease. Fleas from the rats spread the disease to people.C Once people became infected, the disease could be spread from person to person. People became infected as they came in contact with the sick. According to Jean de Venette, a friar who lived at the time, young people were more likely to die than old people. Those who got sick lasted only two or three days and then died suddenly. This happened in such great numbers that often those who lived could not keep up with burying the dead. The friar wrote, Someone who was healthy one day could be dead and buried the next. . . . A healthy person who visited the sick hardly ever escaped death.D No one knows the exact number of plague deaths in Europe. Some guess that about 25 million people died in Europe from 1347 to 1351. This was about one third of the entire population. The death rate varied from place to place. Towns seemed to be harder hit than the countryside. Some entire villages and towns were wiped out. The plague affected the rich as well as the poor. Even the great and powerful, including royalty, were struck down. Throughout Europe, populations were devastated by, as the Welsh called it, death coming into our midst like black smoke.E The Black Death greatly affected Europe. Relations between the upper classes and lower classes changed. Workers, now in short supply, demanded higher wages. In several European countries, peasants staged uprisings. There were emotional effects as well. In some areas, the theme of death appeared in poetry, sculpture, and painting. Peoples faith was shaken. The church lost some of its power and importance. The Black Death took a greater toll on human life than any war or illness before that time. It was perhaps the greatest tragedy in all of European history.It is most likely that disease hit towns harder than the countryside because the towns a.had no policeb.had more ratsc.were not lighted d.were more crowdedPlease select the best answer from the choices providedABCD Biarritz Corp. is growing quickly.

Justinians AccomplishmentsAt the core of Justinians goals as a leader was reestablishing the greatness of the Roman empire. He sought to do this in three ways. First, he engaged in several battles to recapture (take over) the land lost to barbarian invaders during the decline of the Roman empire. Second, rebuilding the capital city of Constantinople after the riots and fires of 532 CE. Third, and most memorable is the drafting of Justinians Code. Justinian set up a commission to collect and revise all of the Roman laws. In 529 CE, Justinian published the first set of laws known as the Body of Civil Law of Justinians Code. The code included laws on marriage, slavery, property ownership, womens rights, and criminal justice. Also included was an outline of the law and a collection of Justinians own new laws. Justinian used the law to unify his empire under his control and provide a sense of stability for his people. Justinians Code did not only have an effect of the Byzantine empire.
