Answer:

Number of chickens = 8

Number of pigs = 16

Step-by-step explanation:

Let the pigs = p

Let the number of chickens = c

Number of heads = 24

p + c = 24 ----------------(I)

p= 24 - c

Number of feet = 80

Chicken has 2 legs and pig has 4 legs

4p + 2c = 80 --------------(II)

Substitute p = 24 - c in equation (II)

4*(24 - c) + 2c = 80

4*24 - 4*c + 2c = 80

96 - 4c + 2c = 80          {Combine like terms}

     96 - 2c = 80        {subtract 96 from both sides}

          -2c = 80 - 96

         -2c = -16          {Divide both sides by (-2)}

           c = -16/-2

          c = 8

Plugin c = 8 in equation (I)

p + 8 = 24

    p = 24 - 8

  p = 16

To predict the cost of driving 1800 miles per month, substitute 1800 in the given function C(d) = 0.2d + 280C(1800) = 0.2 (1800) + 280= $640 per month. Therefore, the cost of driving 1800 miles per month is $640.

(b) Graph is shown below:(c)The slope of the graph represents the rate of change of the cost of driving a car per mile. The slope is given by 0.2, which means that for every mile Lynn drives, the cost increases by $0.2.The y-intercept of the graph represents the fixed cost (amount she pays even if she does not drive).

The y-intercept is given by 280, which means that even if Lynn does not drive the car, she has to pay $280 per month.The linear function gives a suitable model in this situation because the monthly cost increases as the number of miles driven increases.

This is shown by the positive slope of the graph. The fixed cost is also included in the function, which is represented by the y-intercept. Therefore, a linear function is a suitable model in this situation.

Answer:

The order in which you evaluated the expression was a bit incorrect but the outcome either way was 78. In some cases if you evaluate the expression incorrectly or not in order will result in you getting the wrong answer. If you want to see how to evaluate it correctly just look below.

Step-by-step explanation:

PEMDAS stands for

Parenthesis

Exponents

Multiplication and Division ( left to right )

Addition and Subtraction ( left to right )

And it basically tells us the order in which you are suppose to evaluate a mathematical expression.

It appears the expression you are given is 4² + ( 1 × 5 + 7² ) + 8

First we would do the operation inside of the parenthesis

so we have ( 1 × 5 + 7² )

Exponents come before multiplying and addition so first evaluate the exponent, 7² = 49

we now have ( 1 × 5 + 49 )

we next do the multiplication

( 5 + 49 )

Finally we do the addition

5 + 49 = 54.

We then replace the expression ( 1 × 5 + 7² )  with 54 as we just evaluated everything in the parenthesis

we get 4² + 54 + 8

So we just did the parenthesis and next is exponents so lets evaluate the exponents, 4² = 16

16 + 54 + 8

Next in PEMDAS is multiplication and division. There is none so we go to the next step.

We now do the addition and subtraction. ( going left to right )

16 + 54 + 8

first add 16 and 54

70 + 8

finally add 70 and 8

= 78

Notes:

For parenthesis you evaluate everything inside of the parenthesis before you remove the parenthesis

For multiplcation and division, you must evaluate in order going left to right, not doing so can result in a wrong answer.

The sequence {an} = {\(8n^4 + n + 1\)} is not convergent. It diverges to infinity as n approaches infinity.

To determine whether the sequence {an} = {\(8n^4 + n + 1\)} is convergent, we need to examine the behavior of the terms as n approaches infinity.

The sequence {an} is said to be convergent if there exists a real number L such that the terms of the sequence get arbitrarily close to L as n approaches infinity.

To investigate convergence, we can calculate the limit of the sequence as n approaches infinity.

lim(n→∞) \((8n^4 + n + 1)\)

To evaluate this limit, we can look at the highest power of n in the sequence, which is \(n^4.\) As n approaches infinity, the other terms (n and 1) become insignificant compared to n^4.

Taking the limit as n approaches infinity:

lim(n→∞) \(8n^4 + n + 1\)

= lim(n→∞) \(8n^4\)

Here, we can clearly see that the limit goes to infinity as n approaches infinity.

Therefore, the sequence {an} = {\(8n^4 + n + 1\)} is not convergent. It diverges to infinity as n approaches infinity.

Answer:

12 boxes of bookmarks and 8 packs of dust covers.

Step-by-step explanation:

Shelley wants to have at least 250 bookmarks and dust covers for her 250 books.

One box of bookmarks contain 24 bookmarks.

One pack of dust cover contain 36 dust covers.

Shelley buys same number of bookmarks and dust covers.

So, we need to find out LCM(Least Common Multiple) of 24 and 36 to come to a common number that can be bought.

LCM of 24 and 36 is 72.

But, at least 250 bookmarks or dust covers have to be bought. So, we need to find a multiple of 72 which is greater than or equal to 250.

Let us consider the Table of 72:

72, 144, 216, 288, 360 .....

For having enough count of bookmarks and dust covers, at least 288 bookmarks and dust covers have to be bought.

Number of boxes of bookmarks bought = \(\frac{288}{24} \Rightarrow 12\)

Number of packs of dust covers bought = \(\frac{288}{36} \Rightarrow 8\)

12 boxes of bookmarks and 8 packs of dust covers.

You might be a little puzzled by the minus sign in front of the two. You can look at the sequence for the answer. It is going down. A plus 2 would make it go up. Minus signs are always a bit tricky and you have to watch out what you do with them. But the rule is simple

You know that this is an arithmetic sequence because the common difference can be found by adding or subtracting a number from the previous term to get to the next term.

A geometrice sequence would use multiplication or division to get from one term to the next.

A cylinder is a three-dimensional shape that consists of a circular base and a curved surface that extends upward to meet at a point known as the apex. The volume of a cylinder is the amount of space occupied by the shape and is given by the formula V = πr²h, Once we have calculated the area of the circular base, we can multiply it by the height of the cylinder to get the volume.

To calculate the volume of a cylinder, we need to know its dimensions, which are the radius and height. The radius is the distance from the center of the circular base to the edge, while the height is the distance between the two circular bases.

To find the OGF for the number of ternary sequences in which any occurrence of 2 has a 1 both immediately before and immediately after it, we can use a recursive approach.

Let A(x) be the OGF for sequences that start with a 1 and end with a 1. And let B(x) be the OGF for sequences that start with a 1, contain a 2, and end with a 1.

We have A(x) = x + \(x^{2}\) + \(x^{3}\) + \(x^{4}\) + ...

And B(x) = x * \(A(x)^{2}\), since a 2 can only appear after a 1 and must be immediately followed by another 1.

Finally, the OGF for the desired sequence is B(x) = x * x + \(x^{2}\) + \(x^{3}\) + \(x^{4}\) + ...)^2 = x * \(A(x)^{2}\)

So, the OGF for the number of ternary sequences in which any occurrence of 2 has a 1 both immediately before and immediately after it is x * ( x + \(x^{2}\) + \(x^{3}\)......)^2.

The annual percent change in the population of town C will be 16.9

From the formula for the annual increase in population, we have

A = P( 1 + r/100 )n

Where, A = new population

r = rate of increase in the population per annum

n = number of years

Since, from the question, we have

n = 7

A = 3P

Therefore,

3P = \(P( 1+ r/100 )^{7}\)

Or, 3 = \(P( 1+ r/100 )^{7}\)

The given function f(x) = x² + x + 6 has a minimum value. Using the formula x = -b/2a, we find the x-coordinate of the minimum point as -1/2. Substituting this value back into the function, we get a y-coordinate of 5.75. Therefore, the parabola has a minimum value of 5.75. The correct answer is D.

The given function is f(x) = x² + x + 6. We can determine the maximum or minimum value of a parabola by analyzing its quadratic term (x²) coefficient.

In this case, the coefficient of the quadratic term is positive (1), indicating that the parabola opens upwards and has a minimum value.

To find the x-coordinate of the minimum point, we can use the formula x = -b/2a, where a is the coefficient of the quadratic term and b is the coefficient of the linear term.

For our function f(x), a = 1 and b = 1, so the x-coordinate of the minimum point is x = -1/(2*1) = -1/2.

Substituting this value back into the function, we can find the y-coordinate of the minimum point: f(-1/2) = (-1/2)² + (-1/2) + 6 = 1/4 - 1/2 + 6 = 5.75.

Therefore, the parabola modeled by function f has a minimum value of 5.75. Hence, the correct answer is D.
