Find the volume of the solid obtained by rotating the region bounded by the given curves about the x-axis.

y = 3 − 3x^2, y = 0

Answers

Answer: [tex]9.6\pi[/tex]

Step-by-step explanation:

Given

Curve is [tex]y=3-3x^2[/tex]

boundary is y=0 i.e.

[tex]\Rightarrow 0=3-3x^2\\\Rightarrow x^2=1\\\Rightarrow x=\pm 1[/tex]

The volume of solid generated when rotated about the x-axis is

[tex]\Rightarrow V=\int_a^b\pi y^2dx[/tex]

Putting values we get

[tex]\Rightarrow V=\int_{-1}^{1}\pi (3-3x^2)^2dx\\\\\Rightarrow V=\int_{-1}^{1}\pi(9+9x^4-18x^2)dx\\\\\Rightarrow V=\pi \left [ \frac{9x^5}{5} - 6 x^3 + 9 x\right ]_{-1}^{1}\\\\\Rightarrow V=9.6\pi[/tex]

You and a friend go to Tacos Galore for lunch. You order three soft tacos and five burritos and your total bill is $17.75. Your friend orders four soft tacos and two burritos and paid $12.00.

Answers

Answer:

Step-by-step explanation:

let tacos be x and burritos be y

so, your 1st eqn. is 3x + 5y = 17.75

2nd eqn. is 4x+ 2y = 12

Solving the 2 eqns: Multiply eqn 1 with 2 and eqn 2 with 5

So: 6x+10y=35.5

-20x-10y=-60

=-14x=-24.5

x=24.5/14 = 1.75

Substituting the value of x in eqn 1 : (3*1.75)+5y=17.75

y = 2.5

C. 24 units^2
D. 16 units^2

Answers

The answer is A! Hope you have a nice day <3

The surface area of the cone is 16π square units.

What is the surface area of the cone?

The surface area of the cone is given by;

⇒ Area = πrl + πr²

Here, We have;

A right cone has a slant height of 6 and a radius of 2.

Substitute all the values in the formula

⇒ Area = πrl + πr²

⇒ Area = π x 2 x 6 + π x 2²

⇒ Area = 16π

Hence, The surface area of the cone is 16π square units.

Talia grouped the terms and factored out the GCF of the groups of the polynomial 15x2 – 3x – 20x + 4. Her work is shown below.

(15x2 – 3x) + (–20x + 4)
3x(5x – 1) + 4(–5x + 1)
Talia noticed that she does not have a common factor. What should she do?

Talia needs to leave the polynomial as is because it is prime and cannot be factored.
Talia needs to group the terms differently.
Talia needs to factor out a negative from one of the groups so the binomials will be the same.
Talia needs to apply the distributive property to get the expression (3x + 4)(5x – 1).

Answers

Answer:

Talia needs to factor -1 out of one of the two binomials

Step-by-step explanation:

She could take:

3x(5x - 1) + 4(-5x + 1)

and rewrite it as:

3x(5x - 1) - 4(5x - 1)

= (3x - 4)(5x - 1)

The answer is, X = 12.

hope it helps.

Answer:

x = 12

Step-by-step explanation:

simlify 4/3 * (3x-12)

4x - 16 = 2x + 8

combine like terms, so subtract 2x by 4x

2x - 16= 8

then finish combining like terms, so 16 plus 8

2x = 24

divide 24 by 2

x = 12

O A 3+ O B. 323 O a. kl 24 OD. 4 - InstructionsPlease answer the question at the very bottom of this story as a Word document of a PDF. It is the last sentence. In 1990 American playwright Douglas Larche premiered Angels in the Snow: The Berlin Wall Musical Drama. The play tells the story of two couples, a minister and his wife and a young engaged couple, who are separated from one another when the wall goes up overnight. The couples struggle for 28 years to be reunited. As you read the information below about the Berlin Wall, think about what those years might have been like. Then answer the question that follows. In the aftermath of World War II, Germany was divided in two East Germany (under Communist rule) and West Germany (a free, democratic republic). As communism failed to meet peoples needs, more and more refugees began fleeing from East Germany to the west. In the first seven months of 1961 alone, more than 160,000 refugees were counted. East Germany denied plans to build a wall to stop the flood of people. Early in the morning of Sunday, August 13, 1961, however, under the direction of Erich Honecker, the East Germans began to block off East Germany from West Germany by means of barbed wire and antitank obstacles. Workers tore up streets and made barricades from paving stones. Tanks gathered at crucial places. Subway and railway service ceased. Thousands of people from both sides were separated from their homes and families. In the days that followed, East German construction brigades replaced the temporary barriers with a solid wall. The resulting barrier was over 103 miles in length, with more than 66 of those miles being solid wall. Houses near the wall were evacuated, and people approaching the wall were shot. As the world changed, the benefits of freedom and democracy as well as the failings of communism became increasingly evident. In 1989 a massive group of East Germans escaped through Hungary; there were large demonstrations of unrest in Leipzig each Monday. Communist resolve was crumbling, and on November 9, 1989, at about 7:00 P.M., the leader of East Berlins Communist Party, Gnter Schabowski, suggested that the border be opened for private trips abroad. East Berliners rushed to the Brandenburg Gate and West Berliners to the Kurfrstendamm to celebrate. On November 10, demolition work began to create new border crossings. Two days later, the Potsdamer Platz checkpoint was opened. On December 22, a checkpoint for pedestrians opened at the Brandenburg Gate. Wall woodpeckers began hammering out pieces of wall to be sold as souvenirs, and a few larger segments were officially donated or sold. On July 1, 1990, East and West Germany were reunited, and all travel restrictions were dropped. By 1991 the Wall had almost completely vanished. On August 13, 1998, a memorial consisting of about 76 yards of the remaining Berlin Wall was dedicated at Bernauer Street. When Douglas Larche was named playwright-in-residence at the University of Wisconsin-Marinette, his musical about the Berlin Wall was presented as a way to formally introduce him to the public. One reviewer described the songs in the play as beautiful and touching. They include German tunes, Christmas carols, and deep expressions of politics and heartbreak.
