Answers

We can estimate that the weight οf a child will increase by apprοximately 1.93 kg when they grοw frοm a height οf 1 m tο 1.1 m.

What is differential?

A differential equatiοn is an equatiοn that includes an unknοwn functiοn and its derivative. A differential equatiοn describes a relatiοnship between a functiοn and changes in the functiοn.

The given equatiοn relating weight (W) and height (h) fοr children between 5 and 13 years οld is:

ln(W) = ln(2.4) + 1.84h

We want tο estimate the change in weight when a child grοws frοm a height οf 1 m tο 1.1 m.

First, we need tο calculate the weight at h = 1 m and h = 1.1 m.

At h = 1 m, we have:

ln(W1) = ln(2.4) + 1.84(1)

ln(W1) = ln(2.4) + 1.84

ln(W1) ≈ 2.684

Sο the weight at h = 1 m is apprοximately W1 ≈ e².684 ≈ 14.66 kg.

Similarly, at h = 1.1 m, we have:

ln(W2) = ln(2.4) + 1.84(1.1)

ln(W2) = ln(2.4) + 2.024

ln(W2) ≈ 2.807

Sο the weight at h = 1.1 m is apprοximately W2 ≈ e².807 ≈ 16.59 kg.

Tο estimate the change in weight when the height increases frοm 1 m tο 1.1 m, we can use the differential οf the equatiοn:

dln(W) = 1.84dh

Using differentials, we can apprοximate the change in weight as:

dW ≈ W2 - W1

dW ≈ e².807 - e².684

dW ≈ 1.93 kg

Therefοre, we can estimate that the weight οf a child will increase by apprοximately 1.93 kg when they grοw frοm a height οf 1 m tο 1.1 m.

The expected value of the gas grill is 6.50 million dollars if a development cost of $4 million is invested.

What is expected value?

The expected value is the sum of all possible outcomes multiplied by their associated probabilities.

The expected value of the gas grill can be calculated as follows:

Expected value = (0.10 × 3) + (0.50 × 6) + (0.40 × 8)

= 0.30 + 3.00 + 3.20

= 6.50 million dollars

Therefore, the expected value of the gas grill is 6.50 million dollar.

This calculation allows investors to decide whether or not to invest in a specific project, as the expected return must be greater than the development cost.

Answers

Nathaniel hikes 6 2/5 kilometers on each of the second and third days of his hiking trip.

Calculating the distance hiked on the second and third days

If Nathaniel hikes a total of 15 4/5 kilometers on a three-day hiking trip and he hikes 3 kilometers on the first day, then he must hike the remaining distance on the second and third days.

To find out how much Nathaniel hikes on the second and third days, we can start by subtracting the distance he hikes on the first day from the total distance he hikes:

15 4/5 - 3 = 12 4/5 kilometers

Since Nathaniel hikes the same distance on the second and third days, we can divide the remaining distance by 2 to find out how much he hikes on each of those days:

12 4/5 ÷ 2 = 6 2/5 kilometers

Therefore, Nathaniel hikes 6 2/5 kilometers on each of the second and third days of his hiking trip.

Set to 0

So, we have

-0.01q + 5

This gives:

-0.01q = -5

Evaluate

q = 500

Hence, 500 thousand pairs of sunglasses should be sold to maximize profits.

What is the maximum profit?

In (a), we have

q = 500

Answers

Using sine and cosine rule, the length of fence is 19.84 feet and the number of packets to cover the garden is approximately 48

What is the length of fence c?

To find the value of of the length of the fence, we can either use sine rule or cosine rule.

Since we have two sides and an angle, we sine rule first

a/sin A = b / sin B

[tex]\frac{33}{sin 104} = \frac{22}{sin B} \\sin B = 0.6469\\B = 40.31^0[/tex]

Using this, we can find the value of angle C

A + B + C = 180 degrees

Reason: Sum of angles in a triangle is equal to 180 degrees

104 + 40.31 + C = 180

C = 35.69 degrees

We can proceed to use cosine rule to find the length of the fence.

[tex]c^2 = a^2 + b^2 -2(a)(b)cosC\\c^2 = 33^2 + 22^2 - 2(33)(22)cos35.69\\c^2 = 393.71\\c = 19.84 ft[/tex]

Part B

Since one packet will cover 9ft², we need to know the total area of the field to determine the number of packets required.

Using heron's formula;

[tex]s = \frac{a + b + c}{2} \\s = \frac{33 + 22 + 29.84}{2} \\s = 42.42\\[/tex]

The area of the field is

[tex]A = \sqrt{s(s-a)(s-b)(s-c)}\\A = \sqrt{42.42(42.42-33)(42.42-22)(42.42-19.84}\\A = 429.24ft^{2}[/tex]

sue sells rings for 6$ each. Her expenses are $2.50 per ring, plus $56 for supplies. How many rings does she need to sell for her revenue to equal her expenses? Show work to support your answer

Answers

Sue needs to sell 16 rings to make her revenue equal to her expenses

What is revenue?

Revenue is the total income generated by a company or organization from its sales or operations. It is the amount of money that a business earns from selling its products or services, or from other sources such as investments or interest on deposits.

According to question:

Let's assume that Sue sells x rings.

The revenue generated by selling x rings = $6x

The total expenses for selling x rings = $2.50x + $56

To find the number of rings that Sue needs to sell for her revenue to equal her expenses, we need to set the revenue equal to the expenses and solve for x.

6x = 2.5x + 56

Subtracting 2.5x from both sides, we get:

6x - 2.5x = 56

Simplifying the left side, we get:

3.5x = 56

Dividing both sides by 3.5, we get:

x = 16

Therefore, Sue needs to sell 16 rings to make her revenue equal to her expenses.

Correct ___17.65___ bacteria

Find the doubling period.
____?_____ minutes

____?_____ bacteria

When will the population reach 12000.
___?____ minutes

Answers

The population will reach 12000 bacteria after 56.4 minutes and other solutions are listed below

What was the initial size of the culture?

We can use the formula for exponential growth, which is given by:

N = N0 * e^(kt)

where N is the final population, N0 is the initial population, k is the growth rate constant, and t is time.

To find the initial size of the culture, we can use the values given at 15 minutes and 40 minutes:

100 = N0 * e^(15k)

1800 = N0 * e^(40k)

Dividing the second equation by the first, we get:

18 = e^(25k)

Taking the natural logarithm of both sides, we get:

k = ln(18)/25

Solving for k, we get:

k = 0.1156

Substituting this value of k into the first equation, we can solve for N0:

100 = N0 * e^(15 * 0.1156)

N0 = 17.65

Therefore, the initial size of the culture was 17.65 bacteria.

The doubling period

To find the doubling period, we use the fact that the population doubles when t increases by a certain amount, which we'll call T. That is:

N0 * e^(kT) = 2N0

Dividing by N0 and taking the natural logarithm of both sides, we get:

T = ln(2)/k

Solving for T, we get:

T = ln(2)/k ≈ 6.00 minutes

Therefore, the doubling period is approximately 6 minutes.

The population after 115 minutes

To find the population after 115 minutes, we can use the formula with the values of N0, k, and t:

N = N0 * e^(kt) = 17.65 * e^(0.1156 * 115) ≈ 10477448.92

Therefore, the population after 115 minutes is approximately 10477448.92 bacteria.

When the population reaches 12000

To find when the population reaches 12000, we set N equal to 12000 and solve for t:

12000 = 17.65 * e^(0.1156t)

Dividing by 17.65 and taking the natural logarithm of both sides, we get:

ln(12000/17.65 ) = 0.1156t

Solving for t, we get:

t ≈ 56.42 minutes

Therefore, the population will reach 12000 bacteria after approximately 56.4 minutes.

Describe Cosine?

In trigonometry, cosine (cos) is a trigonometric function that relates the adjacent side and the hypotenuse of a right triangle. It is defined as the ratio of the adjacent side to the hypotenuse. The cosine function is periodic with a period of 360 degrees or 2π radians, and it has a range of values between -1 and 1.

In other words, if we have a right triangle with an angle x, then the cosine of x is equal to the length of the adjacent side of the triangle divided by the length of the hypotenuse.

1.In a right-angled triangle, the cosine of an angle is defined as the ratio of the adjacent side to the hypotenuse. Therefore, cos(x) = adjacent/hypotenuse = 37/39.

Using inverse cosine function on a calculator, we get x ≈ 23.6 degrees.

Therefore, the angle between the hypotenuse and the base is approximately 90 - 23.6 = 66.4 degrees.

2. Again, using the definition of cosine, we have cos(x) = adjacent/hypotenuse = 8/17.

Using inverse cosine function on a calculator, we get x ≈ 62.3 degrees.

Answers

We can start by setting up two equations based on the given information:

Equation 1: 0.5x + 0.25y = 3.5
Equation 2: 1x + 0.125y = 4.75

To solve for x and y, we need to eliminate one of the variables. We can do this by multiplying Equation 1 by 2 and subtracting it from Equation 2:

2(0.5x + 0.25y) = 2(3.5)
=> x + 0.5y = 7

1x + 0.125y = 4.75
- (x + 0.5y = 7)
------------------------
-0.375y = -2.25
=> y = 6

Now we can substitute y = 6 into either Equation 1 or 2 to solve for x:

0.5x + 0.25y = 3.5
0.5x + 0.25(6) = 3.5
0.5x + 1.5 = 3.5
0.5x = 2

f'(x) = -148 * (1/2) * (x+1/7)^(-1/2) * 1

f'(x) = -74(x+1/7)^(-1/2)

Therefore, the derivative of f(x) is -74(x+1/7)^(-1/2).

f(x) = x + 1, g(x) = 7x + 8 find (fog)(x)

Answers

Answer:

(fog)(x) = 7x + 9.

Step-by-step explanation:

To find (fog)(x), we need to first find the composition of f and g, which is given by f(g(x)).

So, we substitute g(x) into f(x) and simplify:

f(g(x)) = f(7x + 8)

= (7x + 8) + 1 (using the definition of f(x))

= 7x + 9

Therefore, (fog)(x) = 7x + 9.

Given (x – 7)2 = 36, select the values of x. x = 13 x = 1 x = –29 x = 42

Answers

Answer:

the values of x are 13 and 1.

Step-by-step explanation:

x - 7 = +√36 or x - 7 = -√36

Therefore,

x - 7 = +6 or x - 7 = -6

=> x = 7 + 6 or x = 7 - 6

=> x = 13 or x = 1

Therefore, the values of x are 13 and 1.

Answer: x = 25

Step-by-step explanation:

(x – 7)2 = 36 (Given)

2(x -- 7) = 36 (Associative Property)

2x - 14 = 36 (Distributive Property)

2x - 14 + 14 = 36 + 14 (Addition Property of Equality)

2x = 50 (Simplification)

2x/2 = 50/2 (Division Property of Equality)

x = 25 (Simplification)

x – 19 ≤ 81, if x = 110

Answers

The inequality x - 19 ≤ 81 is not satisfied when x = 110.

What is inequalities?

In mathematics, an inequality is a mathematical statement that indicates that two expressions are not equal. It is a statement that compares two values, usually using one of the following symbols: "<" (less than), ">" (greater than), "≤" (less than or equal to), or "≥" (greater than or equal to).

The given inequality is X – 19 ≤ 81, and we are asked to evaluate it when X = 110. To do so, we substitute X with 110 and simplify the expression. In this case, we get 110 - 19 ≤ 81, which simplifies to 91 ≤ 81. Since this statement is false, we conclude that the inequality X – 19 ≤ 81 is not satisfied when X = 110.

we can substitute x = 110 and simplify:x - 19 ≤ 81

110 - 19 ≤ 81

91 ≤ 81

This statement is false, since 91 is not less than or equal to 81.

Therefore, the inequality x - 19 ≤ 81 is not satisfied when x = 110.

Mr Lim, Mr Bell and Mrs Walker paid for a meal. Mr Lim paid 1/5 of the amount Mr Bell and Mrs Walker paid together. Mr Bell paid 1/4 of the amount Mr Lim and Mrs Walker paid. A) What fraction of the total cost of the meal did Mrs Walker pay?

Answers

As a result, Mrs. Walker contributed a portion of the overall cost of the supper, which is: 400/61 - (16B + 25L) / (61C) (61C)

what is fraction ?

A fraction is a number that in mathematics represents a portion of a whole. It consists of a horizontal line between the numerator and denominator of two numbers. The denominator is the total number of equally sized components that make up the whole, whereas the numerator is the number of parts that are being taken into account. As an illustration, the fraction 3/4 denotes three of the four equal pieces. The denominator, 4, indicates that the entire is divided into four equal parts, while the numerator, 3, indicates that three parts are being taken into consideration.

given

Payment to Mr. Lim:

1/5(B + W) = (B + W)/5

Payment to Mr. Bell:

1/4(L + W) = (L + W)/4

These equations can be combined to find the value of W, or the amount Mrs. Walker paid:

(L + W)/4 + W + (B + W)/5 = C

To get rid of the fractions, multiply both sides by 20, which is the least common multiple of 5 and 4. This gives us:

20W + 4(B + W) + 5(L + W) = 20C

By enlarging and condensing, we obtain:

20C = 4B + 4W + 5L + 5W + 20W

9W + 4B + 5L = 20C

Now, we may change the expressions for the payments made to Mr. Lim and Mr. Bell to:

9W plus 4 (1/5 B + W) plus 5 (1/4 L + W) equals 20C.

If we simplify, we get:

9W + 4B + 4W + 4W + 4W + 5L + 5W = 20C.

When we multiply both sides by 20 to once more get rid of the fractions, we get:

400C = 180W + 16B + 16W + 25L + 25W

20C = 4B + 4W + 5L + 5W + 20W

9W + 4B + 5L = 20C

Now, we may change the expressions for the payments made to Mr. Lim

If we simplify, we get:

61W + 16B + 25L = 400C

We may now determine W:

W = (400C - 16B - 25L) / 61

We can divide W by the overall cost C to determine the portion of the cost of the lunch that Mrs. Walker covered:

W/C = (400C - 16B - 25L) / (61C)

W/C = 400/61 - (16B + 25L) / (simplified) (61C)

As a result, Mrs. Walker contributed a portion of the overall cost of the supper, which is: 400/61 - (16B + 25L) / (61C) (61C) .

Answers

Rieko can make 60 bird houses if each bird house requires 1/4 pounds of nails and she has 15 pounds of nails.

How many bird houses could rieko make

If each bird house requires 1/4 pounds of nails and Rieko has 15 pounds of nails, we can use the following equation to determine the number of bird houses she can make:

number of bird houses = amount of nails / amount of nails per bird house

Plugging in the given values, we get:

number of bird houses = 15 / (1/4)

Simplifying the right-hand side by dividing 15 by 1/4, we get:

number of bird houses = 60

Therefore, Rieko can make 60 bird houses if each bird house requires 1/4 pounds of nails and she has 15 pounds of nails.
