Answer:

Cost equation = 5x + 25000

Step-by-step explanation:

Given: The producing the product is 25,000 plus $5.00 per piece.

x is the number of pieces.

Production cost = fixed cost + cost per piece * number of piece.

Given: Fixed cost = $25000 and cost per piece - $5.00

Now plug in these values in the production cost equation.

So, to produce x number of items, the cost = 25000 + 5x

Which can be written as

Cost equation = 5x + 25000

The correct answer is a. 3x + 6

In order to find a compound function, you must use the first letter in the function (in this case f) and plug the second letter (g) in where you see x's.

f(x) = x + 2

f(g(x)) = (g(x)) + 2

f(g(x)) = (3x + 4) + 2

f(g(x)) = 3x + 6

Final answer:

To find the composition (g ° f)(x), substitute f(x) into g(x) and simplify. The correct answer is 3x + 10.

Explanation:

To find (g ° f)(x), also known as the composition of the functions g and f, you would substitute f(x) into g(x). This means we are looking for g(f(x)):

First, we have f(x) = x + 2.

Then, g(x) = 3x + 4.

To compose g with f, we replace every instance of x in g(x) with f(x). So, g(f(x)) becomes 3(x + 2) + 4.

We simplify this to get 3x + 6 + 4.

And finally, combining like terms gives us 3x + 10.

Therefore, the correct option is (g ° f)(x) = 3x + 10, which is choice b.

Answer:

The amount of money saved will be $0.25

Step-by-step explanation:

Sand sells [tex]8\frac{1}{2}[/tex] cents per pound.

So, the cost of 100 pounds will be:  [tex]8\frac{1}{2}*100=\frac{17}{2}*100 = 850[/tex] cents.

We know that,  1 dollar = 100 cents.

So, 850 cents [tex]=\frac{850}{100} dollar = \$8.50[/tex]

Thus, the amount of money saved by buying 100 pounds at $8.25 will be:  [tex](\$8.50-\$8.25)= \$0.25[/tex]

The amount saved by buying 100 pounds at $8.25 is the change in price per pound and the discounted price, which is 0.25 cents

Price per pound = 8.50 cent

Calculating the cost per pound of of Sand at $100 for $8.25 :

100 = 8.25

1 = p

Cross multiply :

100p = 8.25

p = 8.25 / 100

p = $0.0825 = 0.0825 × 100 = 8.25 cent

The amount saved = 8.50 - 8.25 = 0.25 cent

Therefore, the amount saved by buying 100 pounds at $8.25 is 0.25 cent.

THE QUESTION:After it is purchased, the value of a new car decreases $4000 each year. After 3 years, the car is worth $18,000. What was the original value of the car?

THE WORK: $4000x$3 = $12000_$18000-$12000 = $6000

MY ANSWER: based on my work, the answer is $24000

Final answer:

To find the original value of a car that depreciates by $4,000 each year, we add the total depreciation over 3 years ($12,000) to the car's value after 3 years ($18,000), resulting in an original price of $30,000.

Explanation:

The student is asking about the calculation of the original price of a car given its depreciation rate and its value after a certain period. Since the new car decreases by $4000 each year and after 3 years the value of the car is $18,000, we can calculate the original value by reversing the depreciation.

Depreciation calculation:

Joelle should multiply 792 by 22 to get a perfect square

To figure out the smallest integer that Joelle could have multiplied by 792 to get a perfect square, we need to factorize 792 and ensure all prime factors appear in even powers.

First, we find the prime factorization of 792:

[tex]792 =2^3 \times 3^2 \times 11[/tex]

For a number to be a perfect square, all the exponents in its prime factorization must be even. The exponents of 2 and 11 are not even in this factorization, so we must multiply 792 by the smallest factors that will make these exponents even. So, we need an additional factor of 2 (to make [tex]2^4[/tex]) and an additional factor of 11 (to make [tex]11^2[/tex]). Therefore, we multiply as follows:

[tex]2 \times 11 = 22[/tex]

So, the smallest integer Joelle could have multiplied 792 by to get a perfect square is 22.

Answer:

15 inches

Step-by-step explanation:

Area of a rectangle = width × length

We know the area and length so we can put them into the equasion.

375 in.^2 = width × 25 in.

We know that something times 25 is equal to 375. Therefore, we have to divide 375 by 25, which equals 15.

So, 375 in.^2 = 15 in. × 25 in.

The width of the rectangle is 15 inches.

To find the width of a rectangle, given its length and area, we can use the formula for the area of a rectangle:

Area = Length × Width

We are given that the length of the rectangle is 25 inches and the area is 375 square inches.

Let's substitute these values into the formula:

375 in² = 25 in × Width

To find the width, we need to isolate it on one side of the equation. We can divide both sides of the equation by 25 inches:

375 in² / 25 in = Width

Simplifying the expression:

15 in = Width

Therefore, the width of the rectangle is 15 inches.

Answer:

$5000*0.816 = $4082

Step-by-step explanation:

It's a strange question, but based on the statement and the question it sounds like it's a poisson distribution:

* For 3 days she was able to get 2 good shots (typical of that time of the year)

* Good shots happen randomly

* Each day is independent of another

Let's call 'p' the probability that she makes a good shot per day

Let's call 'n' the number of days Karen is taking shots.

So, if in 3 days he got 2 good shots and that is typical at that time of the year, then the expected value for the number of good shots (X) is:

[tex]E(x)=\frac{2}{3}[/tex]

For a Poisson distribution [tex]E (x)=\lambda\\\lambda= np[/tex]

So:

[tex]\lambda =\frac{2}{3}[/tex]

For a Poisson distribution the standard deviation is:

[tex]\sigma = \sqrt{\lambda}\\\sigma = \sqrt{\frac{2}{3}}[/tex]

[tex]\sigma = 0.816[/tex] this is the standard deviation for the number of buentas taken.

So the standard deviation for income is the price of each shot per sigma

$5000*0.816 = $4082, which is the desired response.

Answer:

17 hours and 3 hours.

Step-by-step explanation:

Let us assume that Annie travels x hours and Brian y hours.

Then given that x = 5y+2

Together they travelled = total hours of both = x+y

Substitute x = 5y+2 in the total distance.

We have an equation in a single variable y as

= 5y+y+2 = 20

Simplify to get

6y+2 = 20

subtract 2

6y = 18

Divide by 6

y =3

x =5y+2

= 5(3) +2=17 hours

Annie traveled 17 hours and Brian 5 hours.

Using the Polynomial Division: Divide 5[tex]x^{4}[/tex]−2[tex]x^{3} -7x^{2} -39 by x^{2}[/tex] +2x−4 using long polynomial division.

Answer to the Polynomial Division: [tex]5x^{2} -12x+37+\frac{-122x+109}{x^{2}+2x-4}[/tex]

The question deals with the division of two polynomial expressions in mathematics. The process involves division of highest degree terms in the polynomials and subtraction of the result from the numerator polynomial, similar to the technique of long division.

The question involves the division of two polynomial expressions, which is a topic in Mathematics, specifically Algebra. The division of polynomials is performed similarly to the long division we use for numbers. In this case, the polynomial (5x^4-2x^3-7x^2-39) is divided by the polynomial (x^2+2x-4).

To perform the division, we divide the highest degree terms in the polynomials. So, we divide 5x^4 (from the numerator polynomial) by x^2 (from the denominator polynomial) to get 5x^2. Multiply this by the entire denominator polynomial and subtract the result from the numerator polynomial. The process is continued until we cannot continue dividing any further.

The result is your answer, which might be another polynomial or a number. Similar to long division with numbers, there might be a remainder after the division.
