The general equation for a circle with center (a,b) and radius r is:

[tex](x-a)^2 + (y-b)^2 = r^2[/tex]. By substituting the values and simplifying the equation, we will get 0.

What is circle ?

In math, a circle is a closed, two-dimensional shape made up of all elements that are spaced uniformly apart from the centre. The radius of something like the circle refers to this distance. Often, the letter "O" or "" is used to represent a circle. The circle is really a fundamental geometric shape and includes a number of significant characteristics, including its radius, which is the distance it around circle, or its area, which is the volume of the circle's interior. A circle's area is equal to 2 times its radius square, and its circumference is equal to 2 times its radius.

To find the equation for the circle that passes through the points (-5,0), (0,4), and (2,4), we need to find the center (a,b) and radius r.

First, we find the midpoint of the line segment between (-5,0) and (0,4), which is:

[tex]((-5+0)/2, (0+4)/2) = (-2.5,2)[/tex]

Next, we find the midpoint of the line segment between (0,4) and (2,4), which is:

[tex]((0+2)/2, 4/2) = (1,2)[/tex]

Since the circle passes through all three points, its center must be equidistant from all three points. Using the distance formula, we can set up three equations:

[tex](-2.5 - a)^2 + (2 - b)^2 = r^2[/tex]

[tex]a^2 + (4 - b)^2 = r^2[/tex]

[tex](1 - a)^2 + (2 - b)^2 = r^2[/tex]

Simplifying the equations and setting them equal to each other, we get:

[tex](-2.5 - a)^2 + (2 - b)^2 = a^2 + (4 - b)^2 = (1 - a)^2 + (2 - b)^2[/tex]

Expanding the squares and simplifying, we get:

[tex]6a - 10 = 0[/tex]

[tex]2b - 12 = 0[/tex]

Solving for a and b, we get:

a = 5/3

b = 6

Now we can find the radius of the circle by plugging in the values of a and b into one of the equations we set up earlier:

[tex]a^2 + (4 - b)^2 = r^2[/tex]

[tex](5/3)^2 + (4 - 6)^2 = r^2[/tex]

[tex]25/9 + 4 = r^2[/tex]

[tex]r^2 = 61/9[/tex]

Therefore, the equation of the circle is:

[tex](x - 5/3)^2 + (y - 6)^2 = 61/9[/tex]

Simplifying, we get:

[tex]4x^2 + 4y^2 - 40x + 48y + 167 = 0.[/tex]

Razak weighs 16.2 kg. To find Razak's weight, we need to use the information given in the problem that his mother weighs 4 times his weight.

Let's use the variable "R" to represent Razak's weight in kilograms. According to the problem, Razak's mother weighs 4 times Razak's weight, so we can write an equation:

Mother's weight = 4 * Razak's weight

64.8 = 4R

To solve for R, we can divide both sides by 4:

64.8 / 4 = R

16.2 = R

Therefore, Razak weighs 16.2 kg.

It's important to note that in solving this problem, we assumed that the weight of Razak's mother was accurately given in the problem. Additionally, we assumed that the units of measurement were in kilograms. If the problem used different units, we would need to convert them to kilograms before solving the equation.

Step-by-step explanation:

I double checked, its right

This would give you a z* value of approximately 1.96.

To find the value of z* for a specified confidence level c in a mosaic function, you should use the inverse cumulative

distribution function (also called the quantile function or the z-score function). The parameters you need are the

desired confidence level (c) and the standard normal distribution.

Here are the steps to find the value of z*

1. Determine the desired confidence level (c). This is usually given as a percentage, like 95% or 99%.

2. Calculate the area under the curve corresponding to the confidence level. This is equal to (1 - c)/2.

3. Use the inverse cumulative distribution function (quantile function) with the standard normal distribution to find the z

score corresponding to the calculated area.

4. The resulting value is the z* value for the specified confidence level c.

For example, if you need to find the z* value for a 95% confidence level, you would calculate (1 - 0.95)/2 = 0.025, and

then use the inverse cumulative distribution function with the standard normal distribution to find the z-score

corresponding to 0.025. This would give you a z* value of approximately 1.96.

Total surface area of this cylinder, the answer is (C) 163.36 cm².

What is an area ?

The total surface area of a cylinder can be found using the formula:

surface area = 2πr² + 2πrh

where r is the radius and h is the height.

Substituting the given values, we get:

surface area = 2π(4.0)² + 2π(4.0)(2.5)

= 2π(16.0) + 2π(10.0)

= 32π + 20π

= 52π

Using the approximation 3.14 for π and rounding to 2 decimal places, we get:

surface area ≈ 52(3.14) ≈ 163.36 cm²

Therefore, the answer is (C) 163.36 cm².

To find the amount of water in each pool at any given time, we need to use the formula:

Amount of water = Initial amount of water + (rate of inflow × time)

Let's say we want to find the amount of water in each pool after 10 minutes. Using the formula, we get:

Amount of water in first pool = 1900 + (21.25 × 10) = 2125 liters

Amount of water in second pool = 1501 + (35.5 × 10) = 501 liters

Therefore, after 10 minutes, the first pool contains 2125 liters of water and the second pool contains 501 liters of water.

The table only gives us information about the values of R and F at certain points in time, but it does not give us a functional relationship between the two variables. To determine whether F is a function of R, we would need to know the number of foxes for each value of R.

A function in mathematics is a rule that converts each element from one set, known as the domain, into a particular element in another set, known as the range. The domain of a function is the set of all potential inputs, whereas the range is the set of all potential outputs. A graph, a table of values, or an equation can all be used to describe a function. In science, engineering, economics, and other disciplines, functions are used to represent the connections between variables.

Neither R nor F is a function of t because there are multiple values of R and F for some values of t. For example, at t=2, the number of rabbits is 750, and at t=3, the number of rabbits is 567.

From the data in the table, we cannot determine whether F is a function of R or whether R is a function of F. To determine whether F is a function of R, we would need to know the number of foxes for each value of R. Similarly, to determine whether R is a function of F, we would need to know the number of rabbits for each value of F.

Assuming a standard six-sided die and a fair coin, the probability of rolling a composite number (any number that is not a prime number) on the die is 3/6 or 1/2, since there are three composite numbers (4, 6, 8) out of six possible outcomes (1, 2, 3, 4, 5, 6).

The probability of the coin landing on heads is 1/2, and the probability of it landing on tails is also 1/2. Therefore, the probability of both events happening together is:

P(composite number and heads and tails) = P(composite number) x P(heads) x P(tails)

P(composite number and heads and tails) = (1/2) x (1/2) x (1/2)

P(composite number and heads and tails) = 1/8

So the probability of rolling a composite number and the coin landing on heads and tails is 1/8.

To find how many students did not like DC superheroes, we need to find the number of students who do not fall into the DC circle:

Students who do not like Marvel superheroes = 358

Students who like both DC and Marvel superheroes = (395 - 240) = 155

Students who like Marvel superheroes only = ?

Students who like DC superheroes only = (240 - 155) = 85

To find how many students like Marvel superheroes, we need to find the number of students who fall into the Marvel circle:

Students who do not like DC superheroes = ?

Students who like both DC and Marvel superheroes = 155

Students who like Marvel superheroes only = ?

Students who like DC superheroes only = 85

To find how many students like both DC and Marvel superheroes, we can use the information we already have:

Students who like both DC and Marvel superheroes = 155

To find how many students like DC but not Marvel superheroes, we can use the information we already have:

Students who like DC superheroes only = 85

To find how many students like Marvel but not DC superheroes, we can use the information we already have:

Students who like Marvel superheroes only = (358 - 155) = 203

Finally, to find how many students do not like the DC or Marvel superheroes, we need to find the number of students who do not fall into either circle:

Students who do not like DC superheroes = ?

Students who like both DC and Marvel superheroes = 155

Students who like Marvel superheroes only = 203

Students who like DC superheroes only = 85

We can now use the formula for the total number of students surveyed to find the number of students who do not like DC or Marvel superheroes:

Total students surveyed = Students who do not like DC superheroes + Students who like both DC and Marvel superheroes + Students who like Marvel superheroes only + Students who like DC superheroes only

560 = Students who do not like DC superheroes + 155 + 203 + 85

Students who do not like DC superheroes = 117

Similarly, we can use the same formula to find the number of students who like Marvel superheroes:

The function of differentiable parameterization of arc length 2 in space is ∫√(1)² + (2t)² + (cos(t))² dt.

To set up a differentiable parameterization of arc-length 2 in space, we can use the arc-length formula:

s = ∫√(dx/dt)² + (dy/dt)² + (dz/dt)² dt

where s is the arc length, t is the parameter, and (x, y, z) is the position vector.

We want the arc length to be 2, so we can set up the following equation:

2 = ∫√(dx/dt)² + (dy/dt)² + (dz/dt)² dt

We can then choose a function for each component of the position vector, such as:

x = t

y = t²

z = sin(t)

We can now find the derivatives with respect to t:

dx/dt = 1

dy/dt = 2t

dz/dt = cos(t)

We can substitute these into the arc-length formula:

2 = ∫√(1)² + (2t)² + (cos(t))² dt

Solving this integral for t will give us the desired parameterization of arc-length 2 in space. However, this integral may not have a closed-form solution, so numerical methods may need to be used to approximate the solution.

180 degrees is how many degrees were in a triangle.

Add up the angles then subtract by 180 and there is your answer.

Therefore, the angle measure indicated 110° that is option A.

An angle is the measure of the amount of rotation between two intersecting lines or planes. It is defined as the space between two intersecting lines or planes measured in degrees, radians, or other units of angular measurement. Angles are often represented by a symbol that looks like a small arc, with three letters labeling the points that define the angle, such as "ABC." The vertex of an angle is the point where the two lines or planes intersect, and the sides of an angle are the two rays that extend from the vertex. Angles are used in geometry, trigonometry, and other mathematical fields to measure and analyze the relationships between shapes and objects.

Here,

Since sector PF has a measure of 90 degrees, then angle PAF must also have a measure of 90 degrees since it is an inscribed angle that intercepts the same arc.

To find the angle measure of QSR, we first need to find the measure of angle QPR.

Since sector PF is a 90 degree sector and line QR is tangent to the circle at point R, we know that angle QRP is a right angle (90 degrees).

Similarly, since sector QR is a 150 degree sector and line PS is tangent to the circle at point S, we know that angle QPS is a right angle (90 degrees).

Therefore, angle QPR + angle QPS = 90 + 90 = 180 degrees.

Since angle QPS and angle QRP share ray QR, they are adjacent angles.

So, angle QSR = 360 - (angle QPR + angle QPS)

= 360 - 180 -70

= 110 degrees

Therefore, the measure of angle QSR is 110 degrees, which is equivalent to a straight line.

The area of the rectangle garden can be expressed as:

Area = Length × Width

Since one side is 6 feet longer than the other, we can express the length as:

Length = Width + 6

Substituting this expression for length into the area formula, we get:

Area = (Width + 6) × Width

Simplifying this expression, we get:

Area = Width² + 6Width

The cost to install synthetic grass is given as $8 per square foot, so the total cost y can be expressed as:

y = 8(Area)

Substituting the expression for area that we found earlier, we get:

y = 8(Width² + 6Width)

Simplifying this expression, we get:

y = 8Width² + 48Width

Therefore, the equation that correctly shows the relationship between x (the length of the shorter side of the garden) and y (the total cost to install synthetic grass) is:

y = 8x² + 48x

The trigonometric ratios of sine, cosine, and tangent can be used  to find the lengths of the sides of the triangle.

A right triangle has one angle that measures exactly 90 degrees. Identify this angle in the triangle.

Label the sides of the triangle as the hypotenuse, adjacent, and opposite sides, relative to one of the non-right angles. The hypotenuse is always the side opposite the right angle.

We know that;

Tan 45 = 5.9/w

As a result, the horizontal component of velocity has a magnitude of 11.8 m/s\ while the vertical component of velocity has a value of 8.0 m/s.

The pace at which an item changes its position is described by a vector quantity called velocity. It is described as the rate at which displacement changes in relation to time The amount and direction of velocity are both present. Speed refers to the velocity's magnitude.

The football's velocity in this scenario is 32 miles per hour, or around 14.3 meters per second.

We can use trigonometry to determine the sizes of a velocity vector's horizontal and vertical components.

Vₓ = V cos (theta), where V is the magnitude of the velocity vector and theta is the angle that the velocity vector makes with the horizontal axis, gives the horizontal component of velocity.

Vy = V sin (theta), where V is the magnitude of the velocity vector and theta is the angle that the velocity vector makes with the horizontal axis, gives the vertical component of velocity.

In this instance, we are aware of the football's velocity, which is 32 miles per hour, or around 14.3 meters per second6. It makes a 34 degree 6 angle with the ground.

Therefore,

Vₓ= V cos (theta) * cos (34 degrees) = 14.3 m/s * 11.8 m/s

Vy = V sin (theta) * sin (34 degrees) = 14.3 m/s * 8.0 m/s
