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

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]

1. The angle between the hypotenuse and the base is approximately 90 - 23.6 = 66.4 degrees. 2. the angle between the hypotenuse and the perpendicular is approximately 90 - 62.3 = 27.7 degrees.

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.

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

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.

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.

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.

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

 To find the derivative of f(x), we can use the power rule and the chain rule.

First, let's rewrite f(x) as:

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

Now, we can apply the power rule:

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

Finally, we can use the chain rule:

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).

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)

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

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.

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.

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.

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.

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
