The length of the side b for the right triangle ABC is equal to 5.276, and the measures of angle A and B are 64 and 26 to the nearest degree using the sine rule.

The sine rule is a relationship between the size of an angle in a triangle and the opposing side.

The side length b is derived using the Pythagoras rule as follows:

b = √(12.2² - 11²)

b = 5.276

Using the sine rule;

12.2/sin90 = 11/sinA

A = sin⁻¹(11 × sin90)/12.2 {cross multiplication}

A = 64.4

12.2/sin90 = 5.3/sinB

B = sin⁻¹(5.276 × sin90)/12.2 {cross multiplication}

B = 25.6

Therefore, the length of the side b for the right triangle ABC is equal to 5.276, and the measures of angle A and B are 64 and 26 to the nearest degree using the sine rule.

Therefore, the length of segment ST is 8/3 cm, assuming that triangles PTQ and RTS are similar.

Triangles are used in various applications, such as in the construction of buildings, bridges, and other structures, as well as in navigation and surveying. They are also important in various fields of mathematics, including trigonometry and geometry.

Here,

Let's denote the length of segment ST as x, and the corresponding sides in triangle PTQ and RTS as y and z, respectively. We can set up the following proportion:

y / PR = z / RT

Substituting the given values, we get:

y / 12 = z / 14

Now, we can use the fact that triangles PTQ and RTS are similar to set up another proportion involving the length of segment ST:

y / x = z / 16

Substituting the value of y / 12 = z / 14 from the first proportion, we get:

(z / 14) / 12 = z / 16 / x

Simplifying this equation, we get:

z = (14 / 12) * (16 / x) * z

z cancels out on both sides, and we are left with:

x = (16 * RT) / (14 * PR)

Substituting the given values, we get:

x = (16 * 14) / (14 * 12)

The value of 2m + k is 14.

The continuity of a function at a point is a fundamental concept in calculus. A function f(x) is said to be continuous at a point x = a

In other words, a function is continuous at a point if we can draw its graph without lifting the pencil from the paper at that point. This means that there are no jumps, breaks, or holes in the graph of the function at that point.

Here we have

To determine if f(x) is continuous at x = 2, we need to check if the left-hand limit and the right-hand limit of f(x) as x approaches 2 are equal, and if they are both equal to f(2).

First, let's calculate the left-hand limit of f(x) as x approaches 2:

lim x → 2- f(x) = lim x → 2- (-x² + 2m) = -(2²) + 2m = 2m - 4

Next, let's calculate the right-hand limit of f(x) as x approaches 2:

lim x → 2+ f(x) = lim x → 2+ (5x - k) = 5(2) - k = 10 - k

Now alculate f(2):

f(2) = -2² + 2m = 2m - 4

For f(x) to be continuous at x = 2, the left-hand limit, right-hand limit, and the function value at x = 2 must all be equal. So we have:

2m - 4 = 10 - k = 2m - 4

Simplifying, we get:

10 - k = 2m - 4

k + 2m = 14

The lower and upper control limits that the manufacturer should use in the resulting control chart are LCL = 0.023,UCL = 0.043

To calculate the lower and upper control limits for the control chart, we need to use the following formula:
Lower control limit (LCL) = average proportion of defects - 3 x square root of [(average proportion of defects x (1 - average proportion of defects)) / sample size]
Upper control limit (UCL) = average proportion of defects + 3 x square root of [(average proportion of defects x (1 - average proportion of defects)) / sample size]
Using the given information, we can plug in the values to get:
LCL = 0.01 - 3 x square root of [(0.01 x 0.99) / 30] = -0.023
UCL = 0.01 + 3 x square root of [(0.01 x 0.99) / 30] = 0.043

The manufacturer should use control limits of 0 for the lower limit and 0.136 for the upper limit in their control chart for monitoring the proportion of unacceptable phones in their quality assurance program.

Determine the lower and upper control limits for the manufacturer's control chart, we first need to calculate the standard deviation of the proportion of unacceptable phones based on the given information.
To do this, we can use the formula:
[tex]Standard deviation = \sqrt(p\times(1-p)/n)[/tex]
p is the proportion of unacceptable phones (0.01), and n is the sample size (30 phones per day for 7 days = 210 total phones).
Plugging in these values, we get:
[tex]Standard deviation = \sqrt(0.01\times(1-0.01)/210) = 0.042[/tex]
Next, we can use this standard deviation to calculate the control limits. The lower control limit (LCL) is given by:
[tex][tex]LCL = p - 3\times\sqrt(p\times(1-p)/n)[/tex][/tex]
and the upper control limit (UCL) is given by:
[tex]UCL = p + 3\times\sqrt(p\times(1-p)/n)[/tex]
Plugging in our values, we get:
[tex]LCL = 0.01 - 3\times0.042 = -0.075[/tex]
[tex]UCL = 0.01 + 3\times0.042 = 0.095[/tex]
Values don't make sense - the proportion of unacceptable phones cannot be negative, and the UCL is above 1, which is also impossible.
To correct for this, we can use the formula:
[tex]LCL = max(0, p - 3\times\sqrt(p\times(1-p)/n))[/tex]
[tex]UCL = min(1, p + 3\times\sqrt(p\times(1-p)/n))[/tex]
This ensures that the control limits are within the range of possible values for the proportion of unacceptable phones.
Plugging in our values with this formula, we get:
[tex]LCL = max(0, 0.01 - 3\times0.042) = 0[/tex]
[tex]UCL = min(1, 0.01 + 3\times0.042) = 0.136[/tex]

[tex]OCF = EBIT + Depreciation - Taxes + \triangle Working Capital[/tex]

where EBIT is earnings before interest and taxes.

Calculate EBIT by subtracting interest expense from operating income:

EBIT = Operating Income - Interest Expense

We do not have the information for operating income, but we can use the fact that interest expense was. [tex]\$165,000[/tex] to calculate EBIT.

EBIT = Interest Expense / (1 - Tax Rate)

= [tex]\$165,000 / (1 - 0)[/tex]

= [tex]\$165,000[/tex]

Calculate the change in working capital (Δ Working Capital). We are told that the company reduced its net working capital investment by [tex]\$69,000[/tex], which means that working capital increased by  [tex]\$69,000[/tex].

Therefore:

[tex]\triangle Working Capital = \$69,000[/tex]

Now, we can calculate OCF:

OCF = EBIT + Depreciation - Taxes + Δ Working Capital

=[tex]\$165,000 + 0 - 0 +\ $69,000[/tex]

=[tex]\$234,000[/tex]

Therefore, the firm’s 2018 operating cash flow (OCF) was [tex]\$234,000[/tex] .

To calculate the net income for Griffin's Goat Farm, we can use the following formula:

Net Income = EBIT - Interest Expense - Taxes

where EBIT is earnings before interest and taxes. We can calculate EBIT as:

EBIT = Sales - Costs - Depreciation

= [tex]\$686,000 - \$332,000 - \$65,000[/tex]

Next, we need to calculate taxes. We are given a tax rate of 24%, so:

Taxes = Tax Rate x (EBIT - Depreciation)

= [tex]0.24 \times (\$289,000 - \$65,000)= \$56,160[/tex]

To write the equation of the line that passes through the points (2, -4) and (0, -4), we can use the point-slope form of a linear equation, which is:

y - y1 = m(x - x1)

Where (x1, y1) is one of the points on the line, and m is the slope of the line.

In this case, both points have the same y-coordinate, which means that the line is horizontal and has a slope of 0. We can choose either point to use in the equation, so let's use (2, -4):

y - (-4) = 0(x - 2)

Simplifying this equation, we get:

y + 4 = 0

y = -4

To summarize, if the equation Hx = c is inconsistent for some c in ℝⁿ, the equation Hx = 0 is consistent because it always has at least one solution, x = 0.

If the equation Hx=c is inconsistent for some c in Rn, then it means that there is no solution for that particular value of c. However, this does not necessarily mean that the equation Hx=0 is also inconsistent. In fact, it is possible for Hx=0 to have a solution, even if Hx=c does not. This is because the equation Hx=0 represents a homogeneous system of linear equations, while Hx=c represents a non-homogeneous system. Homogeneous systems always have at least one solution (x=0), while non-homogeneous systems may or may not have a solution depending on the specific values of the constants involved.
If the equation Hx = c is inconsistent for some c in ℝⁿ, it means that there is no solution for that specific c value.

Now let's analyze the equation Hx = 0.
An equation is inconsistent if it has no solution. On the other hand, if an equation has at least one solution, it is considered consistent.
Since Hx = c is inconsistent for some c in ℝⁿ, it indicates that the rows of the matrix H do not span the entire space of ℝⁿ. In this case, the equation Hx = 0 will always have at least one solution (x = 0), making it a consistent equation. This is because when you substitute x = 0 into the equation Hx = 0, you get 0 = 0, which is always true.

Therefore, we cannot make any conclusions about the consistency of the equation Hx=0 based on the inconsistency of the equation Hx=c.

The actual amount of drink made for the third batch, however, was only 8 liters. This implies that the third batch's recipe contained less pineapple.

We are told that each liter of pineapple juice yields the same amount of drink. This is referred to as the "r" ratio. Then:

r = d/p

We can use the provided data to get a table of r values shown in below image form.

The ratio for the first two data points is the same, but it is different for the third. This suggests the drink's recipe changed between the second and third batches.

We can calculate the ratio using the first two data points:

The total number of kids who enjoy all three drinks is equal to 15 + 10 + 12 - 2 kids who don't like any of the drinks.

Since the number of kids that like none of the drinks is not specified, we can utilise the 33 total kids to find the answer as follows:

Total children - (Total children who like coke + Total children who like orange soda + Total children who like lemonade - Total children who like coke and orange soda) = Total children who don't like any of the drinks. The total number of kids who enjoy coke and lemonade, the total number of kids who enjoy orange soda and lemonade, and the total number of kids who enjoy all three drinks.

33 - (19 + 22 + 16 - 15 - 12 - 10 + Total number of kids who enjoy all three drinks) is the total number of kids who prefer none of the drinks.

To find the number of kids that dislike orange drink, we can now enter all the values we calculated into the original equation.

The sum of the children's numbers is 19 + 22 + 16 - 15 - 12 - 10 + the number of kids who enjoy all three drinks plus the number of kids who don't like any of the drinks.

33 is equal to 19 + 22 + 16 - 15 - 12 - 10 + (15 + 10 + 12 - 2 is the total number of kids who don't like any of the beverages) + Total kids who don't like any of the drinks.

When we simplify this equation, we obtain:

There are 3 kids overall that don't like any of the drinks.

Three kids don't like orange soda, so there.
