Step-by-step explanation:

2 pi r square + pi dh

For this case we have the following functions:

[tex]f (x) = 2x ^ 2-8x + 6\\g (x) = 3x-1[/tex]

We must find f (x) + g (x):

We have to:

[tex]f (x) + g (x) = 2x ^ 2-8x + 6 + (3x-1)\\f (x) + g (x) = 2x ^ 2-8x + 6 + 3x-1[/tex]

We add similar terms:

[tex]f (x) + g (x) = 2x ^ 2-5x + 5[/tex]

Answer:

[tex]f (x) + g (x) = 2x ^ 2-5x + 5[/tex]

OPTION C

Answer:

The total cost of the tent with the markup and then tax applied is $409.86

Step-by-step explanation:

230 is the original

the price is going to increase by 230(.65)=149.5

So the new price is 230+149.5=379.5 (this is before tax is applied)

The sales tax is 8% or .08

So the price is going to increase by .08(379.5)=30.36 (this is the tax to add in)

So the total cost is  379.5+30.36=409.86

Answer:

Cost of the tent: $517.86

Step-by-step explanation:

Since it's marked up by 65%, that means you add an additional $149.59 to $230. Now, you have $479.50. Now with 8% tax, you multiply $479.50 to 0.08 and we get $38.36. We add $38.36 to $479.50 and we get $517.86. I hope this helps and please mark me brainliest!

Answer:

- x

Step-by-step explanation:

If we expand the product.

Each term in the second factor is multiplied by each term in the first factor

x(x - 4) + 3(x - 4) ← distribute both parenthesis

= x² - 4x + 3x - 12 ← collect like terms

= x² - x - 12

The middle term of the product is - x

This question is based on the reasoning. Therefore, the negative slope of the line representing the data in the table.

Given;

A team is selling discount cards as a fundraiser. The table shows the number of cards sold and the remaining amount of money needed.

We have to describe the slope of the line representing the data in the table.

Reasoning: The number of cards sold is represented by x-axis and the amount of money needed is represented  by the y-axis.

In general, as we sell more cards, we gain more money and then,  the amount of money needed goes down.

From the given graph terms, we start at the top of our graph with the amount of money needed and zero cards sold and then as we sell cards your slope of the line goes down and we need less and less money.

Therefore, the negative slope of the line representing the data in the table.

Answer:

C) -4 degrees

Step-by-step explanation:

let's set Sunday Temp = 0°

Since Monday is 6° cooler than Sunday, we subtract 6° from 0 (Sunday's temp)

Monday's Temp -6 (0-6)

Since Tuesday's Temp is 4° higher than Monday, we add 4 to Monday's temp:

Tuesday's Temp -2 (-6+4)

Wednesday's Temp is cooler than Tuesday's but not as cool as Monday's, we assume that Wednesday's Temp is in-between -6 & -2

that makes

c. -4 a reasonable choice

Answer:

C) -4 degrees

Step-by-step explanation:

Let x be the temperature on sunday,

Then, according to the question,

The temperature on monday = x - 6,

On Tuesday = (x-6) + 4 = x - 2,

Now, Wednesday's temperature was cooler than Tuesday's, but not as cool as it was on Monday,

That is,  x - 6 < temperature on wednesday < x - 2

⇒ x- 6 - x < temperature on wednesday - x < x - 2 - x

⇒-6 < temperature on wednesday - temperature on sunday < -2

Since, -6 < -4 < -2

Hence, the possible difference between the temperature on Wednesday, as compared to the temperature on Sunday would be -4.

Option 'C' is correct.

Answer:

$5600

Step-by-step explanation:

Original Cost = x

Total Cost = $5824

Sales Tax = 4% or 0.04

Problem Setup

(Original Cost) + 4% (Original Cost) = Total Cost

x + 0.04x = 5824

1x+ 0.04x = 5824

1.04x = 5824

1.04x/1.04 = 5824/1.04

x=5600 Original Cost

To Check math multiply 5600 x 0.04 = 224.

Then add $5600 + $224 = $5824

The price of the car before sales tax is $5600.  

To determine the cost of the car before sales tax, we can use the equation provided:

[tex]x + 0.04x = 5824[/tex]

Here, [tex]x[/tex] represents the original price of the car before sales tax, and [tex]0.04x[/tex] represents the amount of sales tax, which is 4% of the car's price.

First, combine the terms on the left side of the equation:

[tex]1x + 0.04x = 1.04x[/tex]  

Therefore, the equation simplifies to:

[tex]1.04x = 5824[/tex]

Next, to solve for [tex]x[/tex], divide both sides of the equation by 1.04:

[tex]x = \frac{5824}{1.04}[/tex]

Calculating the right side:

[tex]x = 5600[/tex]

Final answer:

The professor can assign eight different tasks to her eight teaching assistants in 40,320 different ways, calculated by the factorial of eight (8!).

Explanation:

The question pertains to the number of ways to assign eight different tasks to eight teaching assistants. This problem can be solved using the concept of permutations, which is a fundamental principle in combinatorics, a branch of mathematics.

To find the number of different permutations of eight distinct items (the tasks), we would calculate 8!, which signifies factorial of eight. This represents the product of all positive integers up to 8:

Therefore, there are 40,320 different ways the professor can make the assignments to her eight teaching assistants.

The probability that the next post will have 0 comments is P = 4/9.

The probability will be equal to the quotient between the number of posts with no comments and the total number of posts.

We know that there are 9 posts, and by looking at the table, we can see that 4 out of these 9 posts have 0 coments.

Then the probability that the next post will have 0 comments is:

P = 4/9

So the correct option is B.

Answer:

[tex]\begin{aligned}\int{\frac{1}{1 + e^{x}}\cdot dx}= x - \ln(1 + e^{x}) + C\end{aligned}[/tex].

Step-by-step explanation:

The first derivative of the denominator [tex]1 + e^{x}[/tex] is [tex]e^{x}[/tex]. Rewrite the fraction to obtain that expression on the numerator.

[tex]\begin{aligned}\frac{1}{1 + e^{x}} &= \frac{1 + e^{x}}{1 + e^{x}} - \frac{e^{x}}{1+e^{x}}\\&=1-\frac{e^{x}}{1+e^{x}}\end{aligned}[/tex].

In other words,

[tex]\begin{aligned}\int{\frac{1}{1 + e^{x}}\cdot dx} &= \int{dx} - \int{\frac{e^{x}}{1+e^{x}}\cdot dx}\end{aligned}[/tex].

Apply [tex]u[/tex]-substitution on the integral [tex]\displaystyle \int{\frac{e^{x}}{1+e^{x}}\cdot dx}[/tex]:

Let [tex]u = 1 + e^{x}[/tex]. [tex]u > 1[/tex].

[tex]du = e^{x}\cdot dx[/tex].

[tex]\displaystyle \int{\frac{e^{x}}{1+e^{x}}\cdot dx} = \int{\frac{du}{u}} = \ln{|u|} = \ln{u} +C = \ln{(1+e^{x})}+C[/tex].

Therefore

[tex]\begin{aligned}\int{\frac{1}{1 + e^{x}}\cdot dx} &= \int{dx} - \int{\frac{e^{x}}{1+e^{x}}\cdot dx}\\ & = x - \ln{(1 + e^{x})}+C\end{aligned}[/tex].
