Answer:

O C. (f – g)(x) = -3x^2 - x - 4

Step-by-step explanation:

I will assume that f(x) is -4x^2- 6x - 1

f(x) = -4x^2 - 6x - 1

g(x) = -x2 - 5x + 3

(f - g)(x)= -4x^2 - 6x - 1  - (-x2 - 5x + 3)

Distribute the minus sign

(f - g)(x)= -4x^2 - 6x - 1  +x2 + 5x - 3

Combine like terms

(f - g)(x)= -3x^2 - 1x - 4

Answer:

number 2

Step-by-step explanation:

Total number of riders that ride on carpool daily = 2000

Total Cost of one way ticket = $ 5.00

Total Amount earned if 2000 passengers rides daily on carpool = 2000 × 5

                                                                                                            = $10,000

If fare increases by $ 1.00

New fare = $5 + $1    

               = $6

Number of passengers riding on carpool = 2,000 - 100 = 1,900

If 1,900 passengers rides on carpool daily , total amount earned ,if cost of each ticket is $ 6 = 1900 × $6 = $11400

As we have to find the inequality which represents the values of x that would allow the carpool service to have revenue of at least $12,000.

For $ 1 increase in fare = (2,000 - 1 × 100) passengers

For $ x increase in fare, number of passengers = 2,000 - 100·x

                                                         = (2,000 - 100·x) passengers

New fare = 5 + x

New Fare × Final Number of passengers ≥ 12,000

(5+x)·(2,000 - 100 x) ≥ 12,000

5 (2,000 - 100 x) + x(2,000 - 100 x) ≥ 12,000

10,000 - 500 x + 2,000 x - 100 x² ≥ 12,000

100 - 5 x + 20 x - x² ≥ 120

- x² + 15 x +100 - 120 ≥ 0

-x² + 15 x -20 ≥ 0

x² - 15 x + 20 ≤ 0

⇒ x = 1.495

x ≥ $ 1.495, that is if we increase the fare by this amount or more than this the revenue will be at least 12,000 or more .

Also, f'(x) = 0 gives x = 7.5

⇒ The price of a one-way ticket that will maximize revenue is $7.50

Answer:

x=12

Step-by-step explanation:

1/2x + 3 = 2/3x + 1

Subtract 1 from each side

1/2x + 3-1 = 2/3x + 1-1

1/2x +2 = 2/3 x

Subtract 1/2 x from each side

1/2x -1/2x+ 2 = 2/3x -1/2x

2 = 2/3x -1/2x

Get a common denominator of 6  2/3 = 4/6   and 1/2 = 3/6

2 = 4/6x - 3/6x

2 = 1/6 x

Multiply each side by 6 to isolate x

2*6 = 1/6x *6

12 =x

2x - 4 = 0/x

2x - 4 = 0

Step 2: Solve to find x

2x - 4 = 0

2x = 4

x = 4/2

x = 2

Therefore, the value of x after solving is x = 2

Answer:

C.

Step-by-step explanation:

Ok I'm going to make a right triangle by drawing a straight edged line segment from the top left vertex straight down.

We can now find the height of the parallelogram.

sin(60)=h/6  (opp/hyp)

Multiply both sides by 6.

6 sin(60)=h

6*sqrt(3)/2 =h

3*sqrt(3)=h

So to find the area of the parallelogram you do base*height, so you have 8*3*sqrt(3) which simplifies to 24sqrt(3).

Answer:

Step-by-step explanation:

This is a problem of combination.

We will solve this in steps.

First person : He has 5 ways to be seated in the row.

Second person : He has 4 ways to be seated in the row as one seat is already occupied now.

Third  person : He has 3 ways to be seated in the row as two seats are already occupied now.

Forth  person : He has 2 ways to be seated in the row as three seats are already occupied now.

Fifth person : He has only 1 place to sit in the row as four seats are already occupied now.

Hence total number of ways =  5 x 4 x 3 x 2 x 1 = 120

Hence there are 120 ways for five people to be seated  together in a row

The definition of absolute value is the magnitude of a number without the sign.

Hope this helps!

Final answer:

The absolute value of a number indicates its distance from zero on the number line without regard to direction, resulting in a non-negative value. In vectors, the absolute value denotes the magnitude, which is also always positive, even when multiplied by a negative scalar.

Explanation:

Absolute Value Definition

The absolute value of a number is its distance from zero on the number line, regardless of direction. The absolute value of a number is always non-negative, and it is represented by two vertical bars on either side of the number. For instance, the absolute value of -4 is 4, and the absolute value of 4 is also 4. In mathematical notation, this is written as |−4| = 4 and |4| = 4.

In the context of vectors, the absolute value can refer to the magnitude of the vector. When we multiply a vector by a scalar c, the magnitude of the resulting vector becomes the absolute value of cA. If c is positive, the direction of the vector remains the same. If c is negative, the direction is reversed. The magnitude of a vector is always positive, and when calculating the magnitude, we are essentially taking the absolute value of its length.

Significance of the absolute value concept extends to other areas of science as well, such as physics, where it can denote the magnitude of displacement or frequency. For example, the beat frequency between two sounds is defined as the absolute value of the difference between their frequencies because a negative frequency would not make sense.

[tex]41*2=82[/tex]

[tex]41*3=123[/tex] is greater than [tex]85[/tex], so we need to go back down to [tex]41*2=82[/tex].

Now, subtract [tex]85-82[/tex] to get a remainder of [tex]3[/tex].

Answer:

x=2x+6 is the equation that to solve for the smallest.

The three numbers are -6, -4 , and -2.

Step-by-step explanation:

Let x be the smallest of three consecutive even integers.

The next even integer would then have to be x+2 (because x+1 is odd if x is even).

The third one in this sequence would have to be x+4 (because x+3 is odd if x is even).

We are given the first of these numbers equals the sum of the second and third.

So we have x=(x+2)+(x+4).

Combine like terms on right hand side:

x=x+x+2+4

Simplify the combining:

x=2x+6

Subtract 2x on both sides:

x-2x=6

Simplify left hand side:

-x=6

Multiply both sides by -1:

x=-6

If x=-6,  then the three mentioned numbers are:

x=-6

x+2=-6+2=-4

x+4=-6+4=-2

The three numbers are -6, -4 , and -2.

Answer:

When the hot tub is half full, there are 400 gallons of water in it.

Step-by-step explanation:

If 75% or 3/4 of the hot tub is 600 gallons and you need to find 50% or 1/2. Divide 600 by 3 to get 200 then simply multiply by 2 to get 400.

When the hot tub is half full, it would contain 400 gallons of water.

To find out how many gallons are in the hot tub when it's half full, calculate the total capacity of the hot tub using the information that 75% equals 600 gallons. Then, take 50% of that total capacity to find that when the hot tub is half full, it contains 400 gallons.

If a hot tub is 75 percent full with 600 gallons of water, that means the hot tub's total capacity when it's 100% full is larger than 600 gallons. To find out how many gallons are in the hot tub when it's half full, we must first determine the hot tub's total capacity. We can set up a proportion to find the total capacity (T) since 75% of T is 600 gallons.

75% of T = 600 gallons

0.75  imes T = 600 gallons

Now, to find the total capacity (T), divide both sides by 0.75:

T = 600 gallons / 0.75

T = 800 gallons

So, the hot tub's total capacity is 800 gallons. To find the amount of water when the hot tub is half full, simply take 50% of the total capacity:

50% of 800 gallons = 0.5  imes 800 gallons

50% of 800 gallons = 400 gallons

Therefore, when the hot tub is half full, it would contain 400 gallons of water.

The Line has the following equation: y= 1+4/5 x

So we need to know which points: (-5,-3) and (10,9), (-10,-7). (-15, -11) are part of the line

For instances, lest start by evaluating (-15,-11) in y=1+4/5 x

this leaves us to the following operation: -11=1+4/5 * (-15)

-11=1-4*3 resulting in a equality -11=-11, this point does belong to the line

Repeat the above for all of the remaining points and you will get the same conclusion, that is we Vladimir and Robyn are correct.

Answer:

  D  All Of Above

Step-by-step explanation:

Any number that is the ratio of two integers, a repeating decimal fraction, or a value you can write completely without using symbols such as π or √2 is a rational number. All the numbers shown are complete in a finite number of digits, so are rational.

All the provided options (-9, 5/8, and 0) are rational numbers because they can all be expressed as a ratio of two integers or as whole numbers. Hence, the correct answer is 'All of the Above.'

A rational number is one that can be expressed as the ratio of two integers (where the denominator is not zero) or as a whole number. Therefore, -9 (which is a whole number), 5/8 (which is a fraction with both numerator and denominator as integers), and 0 (which can be expressed as 0/1) are all rational numbers. Thus, All of the Above are rational numbers.

Answer:

tan²x + 1 = sec²x is identity

Step-by-step explanation:

* Lets explain how to find this identity

∵ sin²x + cos²x = 1 ⇒ identity

- Divide both sides by cos²x

∵ sin x ÷ cos x = tan x

∴ sin²x ÷ cos²x = tan²x

- Lets find the second term

∵ cos²x ÷ cos²x = 1

- Remember that the inverse of cos x is sec x

∵ sec x = 1/cos x

∴ sec²x = 1/cos²x

- Lets write the equation

∴ tan²x + 1 = 1/cos²x

∵ 1/cos²x = sec²x

∴ than²x + 1 = sec²x

- So we use the first identity sin²x + cos²x = 1 to prove that

 tan²x + 1 = sec²x

∴ tan²x + 1 = sec²x is identity
