if a chicken and a half can lay an egg and a half in a day and a half, how long would it take a pair of chickens to lay three dozen eggs? show your work.

Answers

Answer 1

It would take about 18 days for a pair of chickens to lay three dozen of eggs.

The unitary method is a method for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value. Finding the value of just one unit is the key to answering such questions.

Given that 1.5 chickens can lay 1.5 eggs in a day.

The number of eggs 1 chicken can lay in a day = (1.5/1.5) eggs = 1 egg.

Then, two chickens can lay about 2 eggs in a day.

The number of days it takes for two chickens to lay 3 dozen (3×12=36) eggs is given by

[tex]\frac{\text{total number of eggs}}{\text{number of chicken}}=\frac{36}{2}=18\;\text{days}[/tex]

The answer is 18 days.

Sum of three numbers is 17:
a + b + c = 17
First is 2 greater than two times the third:
a = 2c + 2
Sum of second and third is 9:
b + c = 9
First find the variables in terms of their relationship with other variables. We have variable a because we know that a = 2c + 2. We also know variable b because we have that b + c = 9, so b = 9 - c. We also know variable c because we have that b + c = 9, so c = 9 - b.
Now plug in the equations instead of their variables into the first equation so at the end we would only have one variable, which is easy to figure out.
First get rid of a by putting (2c + 2) instead of it. So the equation would be:
(2c + 2) + b + c = 17.
Then get rid of b by putting (9 - c) instead of it. So the equation would now be:
(2c + 2) + (9 - c) + c = 17.
To simplify this and figure out c, combine like terms so the equation would be:
2c + 11 = 17
Then get c by itself by subtracting 11 from both sides and then dividing both sides by 2 so the equation would be:
c = 3
Once you have c, you can figure out the other numbers by plugging it in:
for example, because a = 2c + 2, just plug in 3 for c to get a = 2(3) + 2, which is 6 + 2, which is 8, so a = 8.
also, because b = 9 - c, just plug in 3 for c to get b = 9 - 3, which is 6, so b = 6.
And since 8 + 6 + 3 = 17, and 8 is 2 greater than 2 x 3, and 6 + 3 = 9, those are the three numbers.

based off of this information, what conclusions can be made about the mean value theorem? this contradicts the mean value theorem since f satisfies the hypotheses on the given interval but there does not exist any c on (1, 4) such that f '(c)

Answers

The correct option is; 4: this contradicts the Mean Value Theorem since there exists a c on (1, 7) such that f '(c) = f(7) − f(1) (7 − 1) , but f is not continuous at x = 3.

Explain the term Mean Value Theorem?The Mean Value Theorem says that there occurs a point c in the interval (a,b) so that f'(c) equals the function's average rate of change throughout [a,b] if a function f is continuous just on closed interval [a,b] as well as differentiable just on open interval (a,b).

The function being used is;

f(x) = (x - 3)⁻²

If we separate this function according to x, we obtain;

f'(x) = -2/(x - 3)³

Finding all c values f(7) − f(1) = f '(c)(7 − 1).is our goal.

This suggests that;

0.06 - 0.25 = -2/(c - 3)³ x 6

-0.19 =  -12/(c - 3)³

(c - 3)³ = 63.157

c = 6.98

If the Mean Value Theorem holds for this function, then f must be continuous on [1,7] and differentiable on (1,7).

But when x = 3, f is not continuous, hence the Mean Value Theorem's prediction is false.

Answers

The value of the function given as (f . g)(2) is D. (f.g)(2) = 44, the number of boats

How to explain the function?

It's important to note that functions are the expressions that are separated by an equal sign. It should be noted that that they've dependent as well as independent variables.

In this case, the function f(x)=2x²+3 represents the rate of a boat traveling with the current in miles per hour and the function g(x)=x+ 2 represents the time the boat traveled in hours. This will be illustrated as:

f(x) = 2x² + 3.

g(x) = x + 2

Therefore, we will evaluate the product

(f . g)(x) = (2x² + 3(x + 2)

(f . g)(x) = (2 × 2² + 3)(2 + 2)

(f . g)(2) = 44

The correct option is D.

After 31 minutes, the airplane has 34,902.5 gallons of fuel. Write a function in f(t) form that describes the amount of fuel in the plane at time t.

Answers

The function in f(t) form that describes the amount of fuel in the plane at time t will be;

⇒ f (t) = 112.25t + 31.425.75

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

After 13 minutes, the airplane has 32,882 gallons of fuel. After 31 minutes, the airplane has 34,902.5 gallons of fuel.

Now,

Since, After 13 minutes, the airplane has 32,882 gallons of fuel. After 31 minutes, the airplane has 34,902.5 gallons of fuel.

Hence, The equation of line passes through the points (13, 32882) and (31, 34902.5)

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (32882 - 34902.5) / ((31 - 13)

m = 2020.5 / 18

m = 112.25

Thus, The equation of line with slope 112.25 is,

⇒ y - 32885 = 112.25 (x - 13)

⇒ y - 32885 = 112.25x - 1459.25

⇒ y = 112.25x - 1459.25 + 32885

⇒ y = 112.25x + 31.425.75

Therefore, The function in f(t) form that describes the amount of fuel in the plane at time t will be;

⇒ f (t) = 112.25t + 31.425.75

The length of the longer leg of a right triangle i 6inche more than twice the length of the horter leg. The length of the hypotenue i 9inche more than twice the length of the horter leg. Find the ide length of the triangle

Answers

The length of shorter leg is 15 inches, length of longer leg is 36 inches and the length of hypotenuse is 39 inches.

What is right triangle?

A right triangle, also known as a right-angled triangle, an orthogonal triangle, or formerly a rectangled triangle, is a triangle with one right angle, meaning that its two sides are perpendicular. Trigonometry's foundation is the relationship between the right triangle's sides and other angle.

Let,

x = Longer leg of triangle

y = Shorter leg of triangle

h = Hypotenuse of triangle

Given: The length of the longer leg of a right triangle is 6inches more than twice the length of the shorter leg.

The length of the hypotenuse is 9inches more than twice the length of the shorter leg.

⇒  x = 6 + 2y

   h = 9 + 2y

The given triangle is a right angled triangle.

⇒                                 x^2 + y^2 = h^2

                         (6 + 2y)^2 + y^2 = (9 + 2y)^2

               36 + 24y + 4y^2 + y^2 = 81 + 36y + 4y^2

                         36 + 24y + 5y^2 = 81 + 36y + 4y^2

36 - 81 + 24y - 36y + 5y^2 - 4y^2 = 0

                            -45 - 12y + y^2 = 0

                              y^2 - 12y - 45 = 0

                      y^2 - 15y + 3y - 45 = 0

                       y(y - 15) + 3(y - 15) = 0

                                (y - 15)(y + 3) = 0

y - 15 = 0,   y + 3 = 0

y = 15,     y = -3

Since the length is not negative.

So, y = 15

Hence,

Shorter leg = 15 inchs

Longer leg = 6 + 2y = 6 + 2(15) = 36 inches

Hypotenuse = 9 + 2y = 9 + 2(15) = 39 inches

a. x = z
b. x + y = 180 degree
c. x + z = 180 degree
d. x + y
e. y + z = 180

Answers

Answer:

Please read the assumptions that lead to the proposed answer of options a, b, and e being correct.  Options c and d are easily rejected.  The question is ambiguous about the locations of the angles.

Step-by-step explanation:

Parallel lines have slopes that are identical.  Lines p and q have the same slopes.

It is difficult imagining what angles are represented by x, y, and z.  There are only 2 lines, and they do not intersect.  The locations of the angles are not identified.  The lack of an intersecting point means it is free range as to where we assign the angles.

The attached graph illustrates some possibilities for x, y, and z.  It uses two simple equations as examples, with the same slope to make them parallel.  Assinment of any angles requires the use of an imaginary line that intersects the two parallel lines.  Even then, there aren't many unique locations for the angles.  To illustrate the analysis, lets assign the angles x, y, and z to thelocations shown on the graph.  

Even with this huge step, there is limited information to be able to identify which of the answer options is correct.  We can say that:

x = z

x+y=180

y+z=180

The answer options (below) appear to have similar relationships, so let's agree that the use of the imaginary line, plus the locations of x, y, and z are valid.  Looking at the answer options, we can match choices a, b, and e to the conclusions above.  d makes no sense because it is not an equation.  c says that both lines must be perpendicular to the x axis, a limitation that is relatively immaterial to whether they are parallel.  The condition of being parallel depends on those two angles being the same (e.g., 45 and 45, 22 and 22, etc.) and not require that they both be 90.

Answer Options               Guarantee Parallel?

a. x = z                                     Yes

b. x + y = 180 degree              Yes

c. x + z = 180 degree              No

d. x + y                                     No

if a lawyer charges 120 an hour(or any fraction of an hour) how much is a mill for 3 hours and 20 minutes?

Answers

If a lawyer charges 120 an hour then the bill for 3 hours and 20 minutes will be 400

Bill: A bill is the printed or written statement of the money owed for goods or services.In later Latin, bulla became billa, and in English billa became bill. The word can still refer to various official documents, such as a proposed law that is brought before parliament, although it is now most commonly used for documents that request payment of money.

One hour = 60 minutes

3 hours and 20 minutes = 3×60 +20

                                        = 180+20=200

Here, one hour=60 minutes charges 120

1 minute charges = 120/60

                             = 2

200 minute charges = 2×200=400

Answers

The probability that the distance between the two points is more than 1/3 is 0.

The length of the given line segment is 1, so the two points chosen independently at random cannot be more than 1 unit apart.

That is, the maximum distance between the two points is 1. However, the question states that we are looking for the probability that the distance between them is more than 1/3.

Since the maximum distance between the two points is 1, and 1/3 is less than 1, it is impossible for the distance between them to be more than 1/3. Therefore, the probability that the distance between the two points is more than 1/3 is 0.

The length, b, of the longest side of the triangle is 13.17 cm

Calculating the length of a side of a triangle

From the question, we are to determine the length, b, of the longest side of the triangle

From the given information,

Area of the triangle = 22.4 cm²

Then, we can write that

22.4 = 1/2 × a × 3.7 sin97

44.8 = a × 3.7 sin97

44.8 = a × 3.6724

a = 44.8/3.6724

a = 12.199

a = 12.2

Given that the sides of the triangle are a, b, and c,

Then,

From the law of cosines, we can write that

b² = c² + a² - 2ac cosB

b² = 3.7² + a² - 2×a×3.7 cos97°

b² = 3.7² + 12.2² - 2×12.2×3.7 cos97°

b² = 3.7² + 12.2² - 2×12.2×3.7 cos97°

b² = 173.53

b = √173.53

b = 13.17 cm

The length of b is 13.17 cm

what is the first word in the alternative statistical hypothesis for any experiment with three levels of a single iv?

Answers

Answer: The first word in the alternative statistical hypothesis for an experiment with three levels of a single independent variable (IV) is "differences." This is because the alternative hypothesis typically involves the existence of differences between the levels of the IV.

Step-by-step explanation:

Here is how to formulate the alternative hypothesis for an experiment with three levels of a single IV:

Identify the independent variable (IV) and the levels of the IV. In this case, there is a single IV with three levels.

Determine the relationship between the IV and the dependent variable (DV). In other words, consider how the levels of the IV may affect the DV.

Write the alternative hypothesis in terms of the relationship between the IV and the DV. The alternative hypothesis should state that there are differences between the levels of the IV in their effect on the DV.

For example, if the IV is "type of exercise" and the levels are "running," "cycling," and "swimming," and the DV is "improvement in cardiovascular fitness," the alternative hypothesis might be "There are differences in the improvement in cardiovascular fitness between the three types of exercise."

What is the null hypothesis in an experiment?

The null hypothesis in an experiment is a statement that there is no relationship between the IV and the DV, or that there are no differences between the levels of the IV in their effect on the DV. The null hypothesis is typically denoted as H0. In the example given above, the null hypothesis might be "There is no difference in the improvement in cardiovascular fitness between the three types of exercise."

This means that the hypothesis is testing whether there are significant differences between the means of the three levels of the IV. Therefore, the first word in the alternative statistical hypothesis for any experiment with three levels of a single IV is "differences."

The first word in the alternative statistical hypothesis for any experiment with three levels of a single IV is "difference," which refers to the difference between the means of the three levels of the IV.

What is hypothesis?

Hypothesis is an educated guess or prediction made in response to a question or problem. It is based on prior knowledge and experience, as well as available evidence. The purpose of a hypothesis is to suggest a possible explanation for an observed phenomenon and then to test the validity of the hypothesis through further research or experimentation. If the hypothesis is proven correct, it can become a theory. Hypotheses can also be disproven or modified through further testing.

This is a reference to the null hypothesis, which states that there is no difference between the means of the different levels of the IV. The alternative hypothesis is that there is a difference between the means of the different levels of the IV.

Find the x and y intercepts
4x - 5y = 40

Answers

Answer:

x-intercept is (10,0)

y-intercept is (0, -8)

Step-by-step explanation:

Our equation is 4x - 5y = 40

Let's find x-intercepts first

X-intercepts is when the y = 0

So we put 0 in for the y, and we have the equation

4x =40

x =10

So our x-intercept located at (10,0)

Now find the y-intercepts

Y-intercepts is when the x = 10

So we put 0 in for the x, and we have the equation

-5y = 40

y= -8

So our y-intercept is located at (0,-8)

Answer:

Step-by-step explanation:

Y-int: (0, -8)

X-Int: (10, 0)

To find the y and x intercepts you have to plug in the 0 for the variable. You'd get 4(0)-5y=40 you get this by plugging in the 0 for x and then you solve. 4 x 0 is 0 so you'd get -5y=40 divide -5 on both sides and get y=-8 meaning that is the y-intercept.

You'd do the same when you look for the x-int. Just that you'd plug in a 0 for y instead of x. Which is 4x-5(0)=40. -5 x 0 is 0. So you'd have 4x=40 divide both sides by 4 and you'd get x=10 meaning that is the x intercept.

Remember that when looking for the y- intercept there should always be a zero in front meaning the x-value, and when looking for the x-intercept there should always be a  zero in the back meaning the y-value.

(Hopefully you were able to understand how I got the x and y intercepts for this equation)

Step-by-step explanation:

the figure above shows the graph of f the derivative of the function f the domain of f is the set

Answers

Since the function increases; stops; and decreases x= -2 has to be a maximum. Similarly, x=0 is a minimum and x=2 is an inflection point. (They are "relative" max/mins as opposed to absolute.

"Critical Points" (maximums, minimum and inflection points) occur when the first derivative of the function is zero. Here f(x) is neither increasing nor decreasing at that exact point. When f '(x) is positive, f(x) is increasing; when f '(x)is negative f(x) is decreasing. In this case, the critical points are x= -2, 0, 2. For x<-2 the derivative is positive so the function is increasing, for x>-2 the derivative is negative so the function is decreasing.

b) When f '(x) is positive, f(x) is increasing; when f '(x) is negative f(x) is decreasing. In this case, the critical points are x= -2, 0, 2. For x<-2 the derivative is positive so the function is increasing, for x>-2 the derivative is negative so the function is decreasing.

Concavity is determined by the second derivative, which is easy to sketch from the first. Where f '(x) is decreasing, f ''(x)is negative; where f '(x) is increasing f ''(x) is positive. Where f '(x) is zero, f ''(x) has critical points. Now from this graph, where f ''(x) is positive, f(x) is concave up, where f ''(x)is negative, f(x) is concave down. I get that f(x) is concave up on(-1,1) and (2,3).

c) Now it should be easy to graph f from the maxs mins and critical points. There is my attempt.

Find a power series representation for the function.f(x) = x8 tan−1(x3)f(x) =[infinity] leftparen1.gifrightparen1.gifsum.gifn = 0

Answers

A power series representation for the function is:

x^8 tan^-1(x^3) = ∑[n = 0 to ∞]  (-1)^n (x^(6n + 11)/2n + 1)

In this question we need to find a power series representation for the function.

f(x) = x^8 tan^-1(x^3)

We know that the Maclaurin series:

1/(1 - x) = ∑[n = 0 to ∞] x^n

Replacing x with -x^2 we get,

1/(1 + x^2) = ∑[n = 0 to ∞] (-x^2)^n

               = ∑[n = 0 to ∞] (-1)^n x^2n

Integrating above equation we get,

tan^-1(x) = ∑[n = 0 to ∞]  (-1)^n (x^(2n + 1)/2n + 1) + c

For x = 0 we get c = 0

so, tan^-1(x) = ∑[n = 0 to ∞]  (-1)^n (x^(2n + 1)/2n + 1)

Now we replace x by x^3, we get,

tan^-1(x^3) = ∑[n = 0 to ∞]  (-1)^n (x^3(2n + 1)/2n + 1)

Therefore, the required power series would be,

x^8 tan^-1(x^3) = ∑[n = 0 to ∞]  (-1)^n (x^(6n + 11)/2n + 1)

This may sound strange, but it is possible. To see why this happens, imagine throwing a tennis ball into the air. The harder you throw the tennis ball, the faster it is traveling when it leaves your hand, and the higher the ball will go before turning back. If you throw it hard enough, it will never return because the gravitational pull will not be able to bring it back down. The velocity, or speed, the ball must have to escape is known as the escape velocity. Earth's escape velocity is about 7 miles a second. As a body is crushed into a smaller and smaller volume, the gravitational pull increases, and the escape velocity gets bigger. Things have to be thrown harder and harder to escape. Eventually, a point is reached when even light, which travels at 186 thousand miles a second, is not traveling fast enough to escape. At this point, nothing can get out as nothing can travel faster than light. This is a black hole.8Which of the following is a good summary of the passage above? A.
