For the polynomial shown below, find f(2).

f(x) = 2x^4+ x^3 - 4x - 3

Answers

Answer 1

Answer:

29

Step-by-step explanation:

Insert 2 in all the x's so, 2(2)^4+(2)^3-4(2)-3

so 32+8-8-3=29

Answer 2

Answer:

f(2)= 29

Step-by-step explanation:

f(x) = 2x^4 + x^3 - 4x -3

all you need to do is to place "2" anywhere you see x in f(x)

2(2)^4 + (2)^3 + 4(3) - 3

32+ 8 - 8 - 3

=29

Answers

Answer:

- 5   (third answer down)

Step-by-step explanation:

12 + 12n = -48

subtract 12 from both sides

12n = - 60

divide both sides by 12

n = - 5

12+12n=-48
Subtract 12 from both sides of the equal signs
12n= -60
Now divide 12 on both sides of equal signs to get variable by itself
n= -5

Answers

[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]

Question : 28

The can is actually cylindrical, so the volume will be :

[tex]\pi {r}^{2} h[/tex]

where,

r = radius = 8/2 = 4 cm

h = height = 30 cm

so,

[tex]3.14 \times 4 \times 4 \times 30[/tex]

[tex]1507.2 \: \: cm {}^{3} [/tex]

Question : 29

Let's find the surface area of can with label :

[tex]2\pi rh[/tex]

[tex]2 \times 3.14 \times 4 \times 30[/tex]

[tex]753.6 \: \: {cm}^{2} [/tex]

Question 30 :

Surface area of entire can ~

[tex]2\pi r(r + h)[/tex]

Pls help asap

Answers

Answer:

x = {0; 2}

Step-by-step explanation:

Given equation:

4x² - 8x = 0

Simplify and factorize:

x² - 2x = 0x(x - 2) = 0x = 0, x - 2 = 0 ⇒ x = 2

Answer:

[tex]x=0, \quad x=2[/tex]

Step-by-step explanation:

Given quadratic equation:

[tex]4x^2-8x=0[/tex]

Factor out the common term 4x:

[tex]\implies 4x(x-2)=0[/tex]

Therefore:

[tex]\begin{aligned}4x & = 0 & \quad \textsf{or } \quad (x-2) & = 0\\\implies x & = 0 & \implies x & = 2\end{aligned}[/tex]

So the solutions to the given quadratic equation are:

1. Write the equation in slope intercept form that represents the line that passes through (-4, -3) and (-2, 1)?

Answers

Answer:

y = 2x + 5

Step-by-step explanation:

Finding the slope:

[tex]\frac{y2-y1}{x2-x1}\\[/tex]

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

= (1+3)/(-2+4)

= 4/2

= 2

Slope: 2

Substituting the slope into the formula 'y=mx+c':

y = 2x+c

Substituting any point (in this case, (-2,1)):

1 = 2(-2) + c

1 = -4 + c

c = 1 + 4

c = 5

Hence,

y = 2x + 5

128 in exponential form

Answers

Answer:

2^12

Step-by-step explanation:

I know that 128 is 32 x 4, so 128 is 2^5 x 2 x 2 = 2^7. Thus,

128 x 32 = 2^5 x 2^7.

The last step is to realize that if two factors have the same base (in this case, both bases are 2), then you can add the exponents:

2^5 x 2^7 = 2^5+7= 2^12.

And that is in exponential form. So the final answer is

128 x 32 = 2^12

Answer:

[tex]128 \: \: is \: \: 32 \times 4, \\ \\ so 128 is  {2}^{5}   \times 2 \times 2 = {2}^{7} . \\ \\ Thus, 128 \times 32 = {2}^{5} \times {2}^{7} .[/tex]

A store decides on the cost of a pair of jeans by tripling their cost and then decreasing it by $15. The cost of the jeans in the store is $105. What does the store pay for the jeans?​

Answers

Answer:

40$

Step-by-step explanation:

if we write it out in an equation, we get

105(final price) = 3x (triple the value they produce it for) - 15 (they degrease it by 15)

subtract 15 from both sides, you get 120 = 3x

divide both sides by 3, you get 40 = x

Exercise #6: Demarco is trying to determine how many pennies he has without having to count
them. He first weighs 20 pennies and finds they have a total weight of 54 grams. He then weighs
all the pennies and finds they weigh a total of 918 grams.
(a) Determine how much a single penny
weighs, i.e. the grams per penny.
(b) Use your answer from (a) to determine
how many pennies Demarco has.

Answers

Step-by-step explanation:

20 pennies weigh 54 grams.

what is the weight of a single penny ?

well, 1/20 of the weight of the 20 pennies.

so,

54/20 = 27/10 = 2.7 grams

all his pennies weigh 918 grams.

how many pennies are there ?

as many as the times the weight of a single penny fit into the total weight.

so,

918 / 2.7 = 9180/27 = 340

he has 340 pennies.

Answer:

1. D.

2. B.

Step-by-step explanation:

1. D. None of the above.

If the three angles of one triangle are congruent to the three angles of another triangle, the triangles are similar, but there is not enough information to prove they are congruent.

2.

The given information gives us a side and an adjacent angle of each triangle.

Since all choices involve sides, we need another pair of sides to use SAS. The angle must be included by the two sides.

We need sides DF and JH to be congruent.

By knowing that DH is congruent to JF, you add HF to both segments giving DF congruent to JH, and the triangles are congruent by SAS.

Answer: B.

Yousef, who remained in California, looked forward to their return. This Afghan American family, however, found themselves dodging gunfire on their return date, trying to force their way into the crowds of people all around the airport at the capital, Kabul. Everyone was trying to get out of the country. Afghanistan's government had collapsed and the Taliban, a militant group that ran Afghanistan in the late 1990s, had seized power again. U.S. troops had been in Afghanistan for 20 years, ever since they helped remove the Taliban from power in 2001. The United States and other Western nations also helped set up a government."Eight Families From California Left Behind"In 2021 the U.S. decided to end its longest war and withdraw its soldiers from the country. Suddenly, however, the government fell and chaos gripped Kabul. In August, U.S. troops hurried to get Americans and allies out of the country, and the last U.S. soldier left on August 31. Yousef's wife and children were among eight families from El Cajon who were left behind. Yousef's family and several other families finally got out of Afghanistan. The Cajon Valley Union School District and their representative in Congress, Republican Darrell Issa, assisted them. Several of the families spoke to reporters last week. Yousef asked that only his first name be used in this story because he still has relatives in Afghanistan who could be at risk. The parents described running with their kids as gunfire whizzed overhead. One father said he was beaten by the Taliban. They said they were kept from getting to the airport by Taliban checkpoints.They said they are grateful to be back in the U.S., but that they worry about the family members unable to get out."Safe At Home Right Now Thanks To God And All Of You""My kids are now safe at home right now thanks to God and all of you," Yousef said.He asked, however, that people not forget the many others left behind. These include U.S. citizens, as well as people with permission to live in the U.S., and Afghans who are at risk because they helped the American government. For the past 20 years, Afghans have worked with U.S. forces to oppose the Taliban. Yousef held a folder that he said contained the documents of 30 people from Afghanistan who qualified for a special immigrant visa. They should be in the United States, he said, but they are still trapped in Afghanistan, desperate to escape.President Joe Biden has said between 100 and 200 Americans were left behind when U.S. troops completed their withdrawal August 31. Many of those left behind are Afghan Americans. The State Department has given no estimate for others who hope to leave Afghanistan. These include U.S. green card holders, people who have permission to live in the United States. Other Afghans received the special visas because they helped Americans during the 20-year war. Congressman Issa said there might be more U.S. citizens and others who were left behind than the U.S. government admits. Yousef said he felt helpless being in California, thousands of miles away, fearing the life he and his family had built would come to a halt and his wife and children would be trapped in Afghanistan ruled by the Taliban. He and his family are all U.S. citizens. They came to this country on a special immigrant visa after Yousef worked for the U.S. government in Afghanistan."U.S. Authorities Escort Family To Airport"Yousef said Issa's team arranged a time for his family to go to the airport with an escort from U.S. authorities. He described talking to Issa's team from where he was in California. At the same time, he was navigating his family through the chaos in Afghanistan.His family returned home to California on Friday, September 3. The first thing he did was take them to IHOP, the International House of Pancakes. It's their favorite restaurant.He hopes more of those happy moments will wipe away the deeply distressing memories his kids have. His 7-year-old son, his youngest, has been talking about the violence."They are talking about it, about the gunfire, and being scared of the Taliban, but we hope they forget all that," said Yousef. He wants them to return to their lives as regular American kids.Questions:Imagine that you are one of Yousefs children. How are you feeling before this trip?How are you feeling during this trip?
