Answer:
The equation of the given circle is:
(x + 3)² + (y + 7)² = 121
This equation is in standard form, which is:
(x - h)² + (y - k)² = r²
where (h, k) is the center of the circle and r is its radius.
Comparing the given equation with the standard form, we can see that:
The center of the circle is (-3, -7) (note the signs of h and k).
The radius of the circle is √121 = 11 (since r² = 121, then r = √121 = 11).
Therefore, the radius of the given circle is 11 units.

Please find attached the graph of the feasible region of the inequality, created with MS Excel
b. The feasible region in the graph of the inequality indicates that the inequality remains true for the coordinates of points within the feasible region
What is an inequality?An inequality is an unequal comparison between values or expressions using inequality symbols such as <, >, ≤, and ≥.
3. The system of inequalities are presented as follows;
4·x + 8·y ≤ -24
-12·x - 4·y < 5
a. Making y the subject of the above inequalities, we get;
4·x + 8·y ≤ -24
y ≤ (-24 - 4·x) ÷ 8 = -3 - 0.5·x
y ≤ -3 - 0.5·x...(1)
-12·x - 4·y < 5
-4·y < 5 + 12·x
y > -1.25 - 3·x...(2)
The solution point is therefore;
-3 - 0.5·x = -1.25 - 3·x
2.5·x = 1.75
x = 1.75/2.5 = 0.7
The x-value of the solution point is therefore the point x = 0.7
y > -1.25 - 3 × 0.7 = -3.35
y > -3.35
The y-value of the solution point is the point y > -3.35
The solution point is therefore the point slightly to the right of the point (0.7, -3.35)
b. The solution space is the triangular region bounded by the points, (0.7, -3.35), (8, -7), and (8, -25.25)
A possible solution obtained from the graph is therefore, the point (6, -10), plugging in the values in the inequalities, we get;
When x = 6
y ≤ -3 - 0.5·x...(1)
y ≤ -3 - 0.5 × 6 = -6
The y-value at the point x = 6 is -10 ≤ -6, which satisfies the first inequality
The second inequality, indicates that we get;
y > -1.25 - 3·x
y > -1.25 - 3 × 6 = -19.25
The y-value at the selected point x = 6 is -10 > -19.25, which satisfies the second inequality
Therefore; The inequality is true at a specified point in the solution space as indicated from the graph

Two concentric circles have radii of 14 and 16. Find the area of the ring. Round to the nearest tenth.
The area of the ring formed by concentric circles is approximately 188.5 square units.
What is area?
An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.
The ring is formed by two concentric circles.
The area of the ring can be found by subtracting the area of the smaller circle from the area of the larger circle.
The area of a circle with radius r is given by the formula A = πr².
So, the area of the larger circle with radius 16 is -
A1 = π(16)² = 256π
And the area of the smaller circle with radius 14 is -
A2 = π(14)² = 196π
Therefore, the area of the ring is -
A ring = A1 - A2
A ring = 256π - 196π
A ring = 60π
To round to the nearest tenth, we can approximate π as 3.14 -
A ring ≈ 60 × 3.14 = 188.4
Rounding to the nearest tenth, we get -
A ring ≈ 188.4 ≈ 188.5
Therefore, the area of the ring is 188.5 square units.

This is the bone density score separating the bottom, 7% from the top 93%
This means that bone density scores below -1.88 are in the bottom 7% of scores, and scores above 1.88 are in the top 93% of scores.
What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
It is relates to bone density score distribution, where the bottom 7% of scores are separated from the top 93% of scores. This could be interpreted in a few different ways, but here's one way to approach it:
If we assume that the bone density scores are normally distributed (which is a common assumption in statistics), then we can use the properties of the normal distribution to estimate the cutoff values for the bottom 7% and top 93% of scores.
The standard normal distribution has a mean of 0 and a standard deviation of 1. Using this distribution, we can look up the cutoff values for the bottom 7% and top 93% of scores using a standard normal distribution table or calculator. These cutoff values represent the bone density scores below which 7% of scores fall and above which 93% of scores fall.
For example, using a standard normal distribution table, we can find that the cutoff value for the bottom 7% of scores is approximately -1.88, and the cutoff value for the top 93% of scores is approximately 1.88.
Therefore, This means that bone density scores below -1.88 are in the bottom 7% of scores, and scores above 1.88 are in the top 93% of scores.

A math teacher gave her class two tests. 25% of the class passed both tests and 42% of the class passed the first test. What percent of those who passed the first test also passed the second test? How would one find the answer to this model?
A) 0.25 divided by 0.67
B) 0.67 divided by 0.42
C) 0.42 divided by 0.67
D) 0.25 divided by 0.42
Answer:
D) 0.25 divided by 0.42.
Step-by-step explanation:
The answer can be found using the formula for conditional probability:
P(B|A) = P(A and B) / P(A)
Let A be the event of passing the first test and B be the event of passing the second test. We know that:
P(A and B) = 25%
P(A) = 42%
To find P(B|A), we need to divide P(A and B) by P(A):
P(B|A) = P(A and B) / P(A) = 0.25 / 0.42
So the answer is D) 0.25 divided by 0.42.
Find the component if the Vector BC if B=(2,-7) and C= (-4,-5)
The component of vector BC in the direction of the x-axis is (-6, 0).
What is the component of the vector on x-axis?
To find the component of vector BC, we need to find the projection of vector BC onto a given vector.
The component of vector BC in the direction of the x-axis can be found using the formula:
comp(x) = (BC · unit(x)) · unit(x)
where;
BC is the vector from B to C, unit(x) is the unit vector in the direction of the x-axis, and comp(x) is the component of vector BC in the direction of the x-axis.To find unit(x), we can use the following formula:
unit(x) = (1, 0)
since the x-axis is the horizontal axis and its unit vector has a horizontal component of 1 and a vertical component of 0.
Now, let's calculate the component of vector BC in the direction of the x-axis:
BC = C - B = (-4, -5) - (2, -7) = (-6, 2)
|BC| = √((-6)² + 2²)
|BC| = √(40)
unit(x) = (1, 0)
(BC · unit(x)) = (-6) · 1 + (2) · 0 = -6
comp(x) = (BC · unit(x)) · unit(x) = (-6) · (1, 0) = (-6, 0)

What is the total amount in Naira that Musa will pay the bank if the commission charged by the bank is 34Naira on each bank draft and he buys a bank draft of (a) $427 (b) £335 (take the exchange rate to be $1=2Naira, £1=15Naira)
Answer:
(a) Musa wants to buy a bank draft for $427. Since $1 = 2 Naira, the cost of the bank draft in Naira will be:
$427 x 2 Naira/$1 = 854 Naira
The commission charged by the bank is 34 Naira on each bank draft, so the total amount in Naira that Musa will pay the bank will be:
854 Naira + 34 Naira = 888 Naira
Therefore, Musa will pay the bank a total of 888 Naira for the bank draft.
(b) Musa wants to buy a bank draft for £335. Since £1 = 15 Naira, the cost of the bank draft in Naira will be:
£335 x 15 Naira/£1 = 5,025 Naira
The commission charged by the bank is 34 Naira on each bank draft, so the total amount in Naira that Musa will pay the bank will be:
5,025 Naira + 34 Naira = 5,059 Naira
Therefore, Musa will pay the bank a total of 5,059 Naira for the bank draft.
a) Musa will pay the bank a total of ₦49,106 (42,700 + 6,406) if he buys a bank draft of $427. The conversion rate is $1 = ₦2 and the charges amount to 34 × 427 = 14,358, so the total amount to be paid is 42,700 + 14,358 = 56,058. Subtracting the commission, the total amount is 56,058 - 6,406 = 49,102.
b) Musa will pay the bank a total of ₦68,030 (50,500 + 17,530) if he buys a bank draft of £335. The conversion rate is £1 = ₦15 and the charges amount to 34 × 335 = 11,290, so the total amount to be paid is 50,500 + 11,290 = 61,790. Subtracting the commission, the total amount is 61,790 - 17,530 = 68,030.

26,510
37,267
15,183
21,746
21,407.
26,154
Answer:
Step-by-step explanation:
To determine the cost of goods manufactured, we need to add up the total manufacturing costs incurred during the month and subtract the cost of work in process inventory on March 1, then add the cost of work in process inventory on March 31:
Total Manufacturing Costs = Cost of Direct Materials Used + Direct Labor + Factory Overhead
Total Manufacturing Costs = $18,435 + $26,510 + $37,267
Total Manufacturing Costs = $82,212
Cost of Goods Manufactured = Total Manufacturing Costs - Work in Process Inventory, March 1 + Work in Process Inventory, March 31
Cost of Goods Manufactured = $82,212 - $15,183 + $21,746
Cost of Goods Manufactured = $88,775
Therefore, the cost of goods manufactured for the month of March is $88,775.
To determine the cost of goods sold, we need to calculate the cost of goods available for sale, which is the sum of the cost of goods manufactured and the cost of finished goods inventory on March 1, and then subtract the cost of finished goods inventory on March 31:
Cost of Goods Available for Sale = Cost of Goods Manufactured + Finished Goods Inventory, March 1
Cost of Goods Available for Sale = $88,775 + $21,407
Cost of Goods Available for Sale = $110,182
Cost of Goods Sold = Cost of Goods Available for Sale - Finished Goods Inventory, March 31
Cost of Goods Sold = $110,182 - $26,154
Cost of Goods Sold = $84,028
Therefore, the cost of goods sold for the month of March is $84,028.

Given the functions f(x)= 1/x-3 -1 and g(x)= 1/x+4-3. Which statement describes the transformation of the graph of the function f onto the graph of the function g.
For the functions f(x)= 1/x-3 -1 and g(x)= 1/x+4-3, the transformation of the graph shows that The graph shifts 7 units left and 2 units down.
What is the definition of a function?
In mathematics, a function is a rule or relationship between two sets of values, known as the domain and the range, that assigns to each element in the domain a unique element in the range.
More formally, a function f is a set of ordered pairs (x, y), where x is an element of the domain and y is an element of the range, such that each element in the domain is paired with exactly one element in the range. This can be written symbolically as:
f: X → Y
where X is the domain and Y is the range, and the arrow → indicates that each element in X is mapped to a unique element in Y.
Now,
To understand the transformation of the graph of the function f onto the graph of the function g, we need to analyze the effect of the changes in the functions.
First, let's consider the function f(x) = 1/(x-3) - 1. This function is a rational function with a vertical asymptote at x = 3 and a horizontal asymptote at y = -1. It is also reflected about the x-axis compared to the basic reciprocal function 1/x.
Next, let's consider the function g(x) = 1/(x+4) - 3. This function is also a rational function with a vertical asymptote at x = -4 and a horizontal asymptote at y = -3. It is also reflected about the x-axis compared to the basic reciprocal function 1/x.
To determine the transformation from f(x) to g(x), we need to compare the changes in the two functions. We can see that:
The term (x-3) in f(x) has been replaced with (x+4) in g(x), which indicates a horizontal shift of 7 units to the left.
The term -1 in f(x) has been replaced with -3 in g(x), which indicates a vertical shift of 2 units down.
Therefore,
the graph of the function f has been shifted 7 units to the left and 2 units down to obtain the graph of the function g. So, the correct statement is:
The graph shifts 7 units left and 2 units down.

Therefore, the value of x is 348 the measure of angle ABD is (0.12x + 67) deg and the measure of angle CBD is (0.13x + 26).
What is angle?An angle is a geometric figure formed by two rays, called the sides of the angle, that share a common endpoint, called the vertex of the angle. Angles are measured in degrees (°) or radians (rad) and are typically denoted by the vertex letter. The size of an angle is determined by the amount of rotation needed to rotate one of the sides of the angle onto the other side. An angle of 90 degrees is called a right angle, an angle less than 90 degrees is called an acute angle, and an angle greater than 90 degrees but less than 180 degrees is called an obtuse angle. Angles are used in a variety of fields, including geometry, trigonometry, and physics, and play an important role in understanding the properties and relationships of shapes and objects.
Here,
Since angles ABD and CBD are adjacent and share side BD, their measures must add up to 180 degrees (since they form a straight line). Therefore, we can write the following equation:
ABD + CBD = 180
Substituting the given measures of angles ABD and CBD, we get:
(0.12x + 67) + (0.13x + 26) = 180
Simplifying the left side of the equation by combining like terms, we get:
0.12x + 0.13x + 67 + 26 = 180
0.25x + 93 = 180
Subtracting 93 from both sides of the equation, we get:
0.25x = 87
Dividing both sides of the equation by 0.25, we get:
x = 348

1.Amy invested £200 into a bank account with 10% simple interest per year. How much money will she have in her account after 2 years?
Answer:
Amy will have £240 in her account.
Step-by-step explanation:
To calculate the amount of money Amy will have in her account after 2 years, we can use the formula:
A = P(1 + rt)
Where:
A = the total amount of money in the account after 2 years
P = the principal (the initial amount of money invested)
r = the interest rate (as a decimal)
t = the time in years
In this case, Amy invested £200 at an interest rate of 10% per year for 2 years. We can plug in these values into the formula and solve for A:
A = 200(1 + 0.1 × 2)
A = 200(1.2)
A = £240
Therefore, after 2 years, Amy will have £240 in her account.

If h(x) = √6 + 5f(x), where f(2)= 6 and f'(2) = 5, find h'(2).
Using chain rule to find the derivative of h(x), the value of h'(2) is 25
What is the value of the functionThe chain rule is a rule in calculus that allows us to find the derivative of a composite function. A composite function is a function that is composed of two or more functions. For example, if we have two functions f(x) and g(x), then the composite function, denoted by h(x), would be h(x) = f(g(x)).
Using the chain rule, we can find the derivative of h(x) with respect to x as follows:
h(x) = √6 + 5f(x)
h'(x) = d/dx (√6 + 5f(x))
h'(x) = d/dx (√6) + d/dx (5f(x))
h'(x) = 0 + 5f'(x)
Now, to find h'(2), we substitute x=2 in the expression above and use the given value of f'(2):
h'(2) = 5f'(2)
h'(2) = 5(5)
h'(2) = 25
Therefore, h'(2) = 25.

the regular price of any souvenir at a gift shop is x dollars. During a sale today, if a customer purchases one souvenir at its regular price, the price of each additional souvenir will be 0.3x less than the regular price. if carmen purchases 10 souvenirs today, and x=$30, what does carmen pay
Answer:
If x = $30 is the regular price of a souvenir, then the sale price for each additional souvenir will be 0.3x = 0.3($30) = $9 less than the regular price. Therefore, the sale price of each additional souvenir will be:
Sale price = Regular price - $9
Sale price = $30 - $9
Sale price = $21
Since Carmen purchases 10 souvenirs, she pays the regular price for the first souvenir and the sale price for the remaining 9 souvenirs. Therefore, the total cost for all 10 souvenirs will be:
Total cost = (Regular price for first souvenir) + (Sale price for 9 additional souvenirs)
Total cost = ($30) + ($21 x 9)
Total cost = $30 + $189
Total cost = $219
Therefore, Carmen pays $219 for 10 souvenirs during the sale.

In a popular shopping centre, the waiting time for an ABC Bank ATM machine is found to be uniformly distributed between 1 and 5 minutes. What is the probability of waiting between 2 and 4 minutes to use the ATM?
The probability of waiting between 2 and 4 minutes to use the ATM is 0. 5 or 50 %.
How to find the probability ?For a uniform distribution, the probability density function is constant within the given interval. In this case, the interval is between 1 and 5 minutes. The length of the interval is 5 - 1 = 4 minutes.
Now, we want to find the probability of waiting between 2 and 4 minutes. The length of this subinterval is 4 - 2 = 2 minutes. To find the probability of waiting between 2 and 4 minutes, we multiply the probability density by the length of the subinterval:
Probability = probability density × (length of subinterval) = (1/4) × 2 = 1/2 = 0.5
So, the probability of waiting between 2 and 4 minutes to use the ATM is 0.5 or 50%.

During her trip kaitlyn's calls to the United States total 100 minutes.What will be the total cost for these calls explain.
The total cost of Kaitlyn's calls to the United States depends on the rate charged by her service provider, and it is important to be aware of any additional fees or charges that may apply.
The total cost of Kaitlyn's calls to the United States depends on the rate charged by her service provider. If Kaitlyn has a plan with a specific rate for international calls, her total cost can be calculated by multiplying the number of minutes by the rate. For example, if her plan charges $0.10 per minute, then 100 minutes of calls would cost $10. However, if Kaitlyn does not have a plan that includes international calls, the cost per minute may be significantly higher, and there may be additional fees or charges. Therefore, it is important to check with the service provider for specific rates and fees before making international calls. It may be beneficial for Kaitlyn to consider purchasing an international calling plan or using a calling app to minimize costs. Overall, the total cost for Kaitlyn's calls to the United States will depend on the specific rate charged by her service provider, and it is important to be aware of any additional fees or charges that may apply.

[9-A] Let f: R→→R be defined by the formula
The values οf a and b that make the functiοn f cοntinuοus at x = -2 and x = 3 are a = -2 and b = 1
Describe Functiοn?A functiοn is said tο be cοntinuοus if it has nο jumps, breaks, οr hοles in its graph. In οther wοrds, a functiοn is cοntinuοus if it can be drawn withοut lifting the pen frοm the paper. Fοrmally, a functiοn is cοntinuοus at a pοint x = c if the limit οf the functiοn as x apprοaches c frοm bοth the left and the right exists and is equal tο the value οf the functiοn at c.
Fοr example, the functiοn f(x) = x² is cοntinuοus everywhere because it is a smοοth curve with nο jumps οr breaks in its graph. On the οther hand, the functiοn g(x) = 1/x is cοntinuοus everywhere except at x = 0, where it has a vertical asymptοte and a hοle in its graph.
The cοncept οf cοntinuity is impοrtant in many areas οf mathematics, including calculus and analysis, as it allοws us tο study the behaviοr οf functiοns at specific pοints and οver intervals. It is alsο impοrtant in real-wοrld applicatiοns, such as in engineering and physics, where cοntinuοus functiοns mοdel physical phenοmena like mοtiοn, heat transfer, and fluid flοw.
Tο find the values οf a and b, we can use the cοntinuity οf the functiοn at x = -2 and x = 3. Fοr a functiοn tο be cοntinuοus at a pοint, it must exist at that pοint and its limit as x apprοaches that pοint frοm bοth sides must be equal.
At x = -2:
The left-hand limit οf f(x) as x apprοaches -2 is f(-2-) = 2(-2)² - 3 = 5.
The right-hand limit οf f(x) as x apprοaches -2 is f(-2+) = a(-2) + b.
Since the functiοn is cοntinuοus at x = -2, these limits must be equal:
f(-2-) = f(-2+) => 5 = -2a + b
At x = 3:
The left-hand limit οf f(x) as x apprοaches 3 is f(3-) = a(3) + b.
The right-hand limit οf f(x) as x apprοaches 3 is f(3+) = (6/3) - 3 = -1.
Since the functiοn is cοntinuοus at x = 3, these limits must be equal:
f(3-) = f(3+) => a(3) + b = -1
We nοw have twο equatiοns with twο unknοwns:
5 = -2a + b
a(3) + b = -1
Sοlving fοr b in terms οf a in the first equatiοn gives:
b = 2a + 5
Substituting this expressiοn fοr b intο the secοnd equatiοn gives:
a(3) + 2a + 5 = -1
3a + 5 = -1
3a = -6
a = -2
Substituting this value οf a intο the first equatiοn gives:
5 = -2(-2) + b
5 = 4 + b
b = 1
Therefοre, the values οf a and b that make the functiοn f cοntinuοus at x = -2 and x = 3 are a = -2 and b = 1.
