How to get the centre of the circle when the circumference is not given

Answer:

Using the Distance Formula:

EG =√((-a - b)^2) + (0 - c)^2)

=√((a + b)^2 + c^2)

FH =√((-b - a)^2 + (c - 0)^2)

=√((a + b)^2 + c^2)

So EG = FH.

A positive integer is 40 more than 29 times another. Their product is 10116 these two integers are 19 and 571.

In mathematics, an integer is a whole number that can be positive, negative, or zero. Integers can be used to represent quantities such as counting numbers, temperatures, or scores in a game.

Let's call the two integers x and y, where x is the larger integer and y is the smaller integer.

From the problem, we know that:

x = 29y + 40 (equation 1)

xy = 10116 (equation 2)

We can substitute equation 1 into equation 2 to get:

(29y + 40)y = 10116

Expanding and simplifying:

29[tex]y^{2}[/tex]+ 40y - 10116 = 0

We can use the quadratic formula to solve for y:

y = (-40 ± √([tex]40^{2}[/tex] - 429(-10116))) / (2×29)

y = (-40 ± √308576) / 58

y ≈ 18.95 or y ≈ -12.3

Since y is a positive integer, we can round up to 19.

Now we can use equation 1 to find x:

x = 29y + 40

x = 29(19) + 40

x = 571

Therefore, the two integers are 19 and 571.

Based on the given information, we can conclude that the graph represents a quadratic function. The vertex of the parabola is located at (0, 9) and the function passes through several points including (-4, -7), (-3, 0), (3, 0), and (4, -7).

To find the equation of the function, we need to determine the value of "a" in the equation f(x) = ax^2 + bx + c. Since the vertex is located at (0, 9), we know that the x-coordinate of the vertex is 0. Therefore, we can use the vertex form of the equation, which is f(x) = a(x - 0)^2 + 9, or simply f(x) = ax^2 + 9.

Next, we can use one of the given points to solve for "a". Let's use the point (-3, 0).

0 = a(-3)^2 + 9

0 = 9a - 9

9 = 9a

a = 1

Therefore, the value of "a" in the equation of the function is B. 1.

The volume of the largest right cylinder that fits in a sphere of radius 4 is 128π cubic units.

To find the volume, we need to understand that the cylinder that fits inside a sphere will have its height (h) equal to the diameter of the sphere (2r), and the cylinder's radius (r') will also be equal to the sphere's radius (r).

We can use the formula for the volume of a cylinder: V = π[tex]r^2^h[/tex], where π is pi (approximately 3.14), r is the radius, and h is the height.

Since the cylinder's height is equal to the sphere's diameter, which is 2r, the height of the cylinder is 2r. Therefore, we can write the volume of the cylinder as:

V = πr²(2r)

Simplifying this expression, we get:

V = 2π[tex]r^3[/tex]

To find the maximum volume of the cylinder that fits inside a sphere of radius 4, we need to maximize the volume by finding the maximum value of r. Since the radius of the cylinder is equal to the radius of the sphere, we have:

r = 4

Substituting this value into the formula for the volume of the cylinder, we get:

V = 2π[tex](4)^3[/tex]

V = 128π

To evaluate the limit using L'Hospital's rule, we need to take the derivative of both the numerator and denominator separately until we get a determinate form. We have:

lim (e^x + 2x - 1) / (2x)

Taking the derivative of the numerator:

lim (e^x + 2) / 2

Taking the derivative of the denominator:

lim 2

Since we now have a determinate form, we can evaluate the limit by plugging in the value of x. We get:

(e^x + 2) / 2

As x approaches infinity, e^x also approaches infinity, so the limit diverges to positive infinity. Therefore, the limit does not exist.

Using the Mean Value Theorem, we have proven that √(6a+3) < a + 2 for all a > 1.

To prove √(6a+3) <a + 2 for all a > 1 using the Mean Value Theorem, we will begin by defining a function f(x) as:

f(x) = √(6x+3)

We can see that f(x) is a continuous and differentiable function for all x > -1/2.

Now, let's choose two values of a, such that a > 1 and b = a + h, where h is a positive number. By the Mean Value Theorem, there exists a value c between a and b such that

f(b) - f(a) = f'(c)(b-a)

where f'(c) is the derivative of f(x) evaluated at c.

Now, let's evaluate the derivative of f(x) as:

f'(x) = 3/(√(6x+3))

Thus, we can write

f(b) - f(a) = f'(c)(b-a)

√(6(a+h)+3) - √(6a+3) = f'(c)h

Dividing both sides by h and taking the limit as h → 0, we get

lim h→0 (√(6(a+h)+3) - √(6a+3))/h = f'(a)

Now, we can evaluate the limit on the left-hand side using L'Hopital's rule

lim h→0 (√(6(a+h)+3) - √(6a+3))/h = lim h→0 [3/(√(6(a+h)+3)) - 3/(√(6a+3))] = 3/(2√(6a+3))

Therefore, we have

f'(a) = 3/(2√(6a+3))

Now, we can use this value to rewrite the inequality as

√(6a+3) - (a + 2) < 0

Multiplying both sides by 2√(6a+3) and simplifying, we get

3 < 4a + 2√(6a+3)

Subtracting 4a from both sides and squaring, we get

9 < 16a^2 + 16a + 24a + 12

Simplifying, we get

0 < 16a^2 + 40a + 3

This inequality holds for all a > 1, so we have proved that

Jones would save $20 over 2 months by choosing Texas Bank over Lone Star Bank for his online banking needs.

To answer this question, we need to know the fees and charges associated with online banking at Texas Bank and Lone Star Bank. Without this information, it's impossible to accurately calculate how much Jones would save by choosing one bank over the other.

Assuming we have this information, we can use the following steps to calculate Jones' potential savings:

Calculate the fees and charges associated with 40 transactions per month at each bank.

Subtract the total fees and charges at Texas Bank from the total fees and charges at Lone Star Bank to determine the difference.

Multiply the difference by 2 to determine how much Jones would save in 2 months by choosing Texas Bank over Lone Star Bank.

For example, let's say that the fees and charges at Lone Star Bank for 40 transactions per month total $20, while the fees and charges at Texas Bank for the same number of transactions total $10. In this case, the difference would be $10 per month.

To calculate Jones' potential savings over 2 months, we would multiply $10 by 2, giving us a total potential savings of $20.

The measure of ∠O in ΔMNO is approximately 41.5°.

To find the measure of ∠O, we can use the Law of Cosines in ΔMNO, with sides M = 540 inches, N = 330 inches, and O = 600 inches. The Law of Cosines states:

O² = M² + N² - 2MN * cos(∠O)

Rearrange the equation to solve for cos(∠O):

cos(∠O) = (M² + N² - O²) / (2MN)

Substitute the values:

cos(∠O) = (540² + 330² - 600²) / (2 * 540 * 330)

cos(∠O) ≈ -0.7944

Now, find the angle using the inverse cosine function:

∠O ≈ arccos(-0.7944) ≈ 141.5°

Since ∠O is an obtuse angle, we need to find its supplement to the nearest 10th:

The direction angles of a vector are the angles that the vector makes with the positive x, y, and z axes. To find the direction angles of the vector u = (-1, 9, -6), we can use the formulas:

cosθx = u_x/||u||, cosθy = u_y/||u||, and cosθz = u_z/||u||

where θx, θy, and θz are the angles that u makes with the x, y, and z axes, respectively, and ||u|| is the magnitude of u, given by:

||u|| = √(u_x² + u_y² + u_z²)

Substituting the values of u, we have:

||u|| = √((-1)² + 9² + (-6)²) = √118

cosθx = -1/√118 ≈ -0.183, cosθy = 9/√118 ≈ 0.551, and cosθz = -6/√118 ≈ -0.366

Taking the inverse cosine of each of these values, we get:

So, the equation we could use to find Jeremy's age, j, if he is the younger man, is: j = x + 2, where x satisfies the equation x(x + 2) = 783.

An equation is a mathematical statement that asserts the equality of two expressions. In an equation, an expression is written on the left side of an equals sign (=), and another expression is written on the right side of the equals sign. The equals sign indicates that the two expressions have the same value.

Here,

Let's use algebra to solve this problem. We can start by representing Sam's age as x and Jeremy's age as x + 2, since they are consecutive odd integers. We know that the product of their ages is 783, so we can set up the following equation:

x(x + 2) = 783

We can simplify this equation by multiplying out the left side:

x² + 2x = 783

Now we have a quadratic equation in standard form. We can solve for x by using the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

In this case, a = 1, b = 2, and c = -783, so we can substitute these values into the formula:

x = (-2 ± √(2² - 4(1)(-783))) / 2(1)

Simplifying the expression under the square root, we get:

x = (-2 ± √(3136)) / 2

x = (-2 ± 56) / 2

So, we have two possible values for x:

x = 27 or x = -29

We can reject the negative value, since it does not make sense in the context of the problem. Therefore, we have:

x = 27

Now we can use this value to find Jeremy's age, which is x + 2:

j = x + 2

= 27 + 2

The height of the wooden post cap is approximately 11.34 centimeters.

To find the height of the wooden post cap, we need to use the formula for the volume of a square pyramid which is V = (1/3) Bh, where B is the area of the base and h is the height. Since we know that each post cap has a volume of 94.5 cubic centimeters, we can plug this into the formula to get:

94.5 = (1/3) B h

We also know that the base of the pyramid is a square, so the area of the base is equal to s², where s is the length of one side. Since we don't know the length of the side or the height of the pyramid, we need to use another piece of information. Let's assume that the fence posts are all the same height and that the caps fit snugly on top of them. If we measure the height of the fence post, we can use this to find the height of the cap.

Let's say that the height of the fence post is 10 centimeters. We can use this to find the area of the base:

B = s² = (10/2)² = 25 square centimeters

Now we can plug this into the formula:

94.5 = (1/3) (25) h

Simplifying this equation, we get:

h = (94.5 * 3) / 25 = 11.34 centimeters

This family can claim a tax credit of up to R310 per month for the main member and the first dependent, and R209 per month for each additional dependent. This tax credit is only applicable to registered medical schemes and is deducted from the tax payable.

In addition to medical aid expenses, this family will also need to consider the 15% VAT payable on all goods and services, except for sanitary pads, fresh produce, and a few other staple food items. This means that if this family spends R10,000 on goods and services, they will need to pay an additional R1,500 in VAT.

However, the good news is that they won't have to pay VAT on their fresh produce and staple food items. This will help to reduce their overall expenditure on food, which is an essential expense for every family.

In conclusion, while this family will need to pay VAT on most goods and services, they can claim a tax credit for their medical aid expenses. Additionally, they won't have to pay VAT on fresh produce and staple food items, which will help to reduce their overall food expenditure.

By carefully managing their expenses and taking advantage of tax credits and exemptions, this family can ensure that they are able to provide for their essential needs while also managing their financial obligations.

The probability of hitting the bulls eye (center circle) when we shoot an arrow with radius of the bulls eye is 2ft and the radius of the target is 6ft is 11.1%.

Assuming that we are shooting randomly at the target and the arrow can land anywhere within the target area, the probability of hitting the bull's eye (center circle) can be calculated as the ratio of the area of the bull's eye to the area of the entire target.

The area of the bull's eye can be calculated as follows:

Area of bull's eye = π x (radius of bull's eye)²
Area of bull's eye = 3.14 x 2²
Area of bull's eye = 12.56 square feet

The area of the entire target can be calculated as follows:

Area of target = π x (radius of target)²
Area of target = 3.14 x 6²
Area of target = 113.04 square feet

Therefore, the probability of hitting the bull's eye can be calculated as:

Probability of hitting bull's eye = Area of bull's eye / Area of target
Probability of hitting bulls eye = 12.56 / 113.04
Probability of hitting bulls eye = 0.111 or approximately 11.1%

So, the probability of hitting the bull's eye (center circle) when we shoot an arrow randomly at the target is approximately 11.1%.
