Option A : The circle represented in the third quadrant has the centre lying at (-3, -1)

The location of a circle in the Cartesian plane is represented by a circle equation. We can construct the equation for a circle if we know the location of the circle's center and how long its radius is. All of the points on the circle's circumference are represented by the circle equation.

The group of points whose separation from a given point has a constant value are represented by a circle. The radius of the circle, abbreviated r, is a constant that describes this fixed point, which is known as the circle's center. The equation (x- x₁)²+(y-y₁)²=r²describes a circle with a center at (x₁,y₁) and a radius of r.

There are different forms to represent the equation of a circle :

The equation of the circle is

(x + 3)² + (y + 1)² = 9

The centre of the circle will be at (-3, -1) from the equation .

Answer: Given the function f(x) = -3x^3 +3x^2+ 3x + 3, the following is true:

-It is not necessarily positive or negative as the value of f(x) depends on the value of x.

-It is a cubic function as it contains an x^3 term.

-The domain is all real numbers as there are no restrictions on the input x.

-It has at most 3 solutions as it is a cubic function and cubic functions can have at most 3 real roots.

-It is a polynomial function as it is a finite sum of terms involving non-negative integer powers of x.

Step-by-step explanation:

Answer: The constant of proportionality and the unit rate represent the same value. A constant of proportionality can be any value, including fractions and decimals. The main difference between the constant of proportionality and a unit rate is how they are written.

The required inequality is 437 + 36x ≥ 500, where x is the number of miles he should walk each day to meet his goal.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

Given,

His trip length was 437 miles, and he had 36 days left.

If x is the number of miles covered each day, then the remaining miles to

Then the remained miles to cover = number of days remained × miles  covered in each day

Thus, his trip length = already completed miles + remaining miles

= 437 + 36x

As per the question,

Total miles ≥ 500 miles

⇒ 437 + 36x ≥ 500

Thus, the required inequality is 437 + 36x ≥ 500.

The new average of the students is 25.368.

In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.

Given that, in a group of 24 students attending a party, the average age is 25.3 years.

A 27-year-old student joins the party.

So, the new average is (24×25.3+27)/25

The area of the rectangle is given by the equation A = ( 9x² - 64 ) yards²

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the rectangle be represented as A

Now , the equation will be

Let the width of the rectangle be W = ( 3x - 8 ) yards

Let the length of the rectangle be L = ( 3x + 8 ) yards

Step-by-step explanation:

A line running through the points (2, 0) and (0, 4) has a slope of -2.

The slope of a line is defined as the change in y-axis of the line to the x-axis. Mathematically, it is expressed as:

Slope = Δy/Δx

Using the coordinate points (2, 0) and (0, 4) to determine the required slope:

Slope = 4-0/0-2
Slope= 4/-2
Slope = -2

If from the top of a 72 m high vertical cliff, a boat has an angle of depression of 32° then  the distance of boat from the base of the cliff is, 115 m.

An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.

Interior angles:- The inner angle made by the intersection of two polygonal sides.

Exterior angles:- The outer angle made by the intersection of two polygonal sides.

We can use trigonometry to solve for the distance of the boat from the base of the cliff.

Let's call the distance from the base of the cliff to the boat "d".

Then we have:

tan(32°) = 72 / d

Solving for d, we get:

d = 72 / tan(32°)

d = 115.22

Rounding to the nearest whole number, d = 115.

So the boat is 115 meters away from the base of the cliff.

A coterminal angle is an angle that has the same initial point as another angle but has a different measure.

A coterminal angle is an angle that has a different measure in degrees from another angle but the same initial point and direction. It is an angle that is similar to another angle in orientation but may be different in size. Coterminal angles are significant in trigonometry and have numerous uses in physics, engineering, and mathematics.

Angles are frequently measured in degrees in mathematics, and they can have a value between 0 and 360. It's crucial to remember that different measures might be assigned to the same angle based on the starting and finishing points. For instance, a 90-degree angle is one that begins at the positive x-axis and ends at the positive y-axis. Additionally, the same angle can be expressed as 450 degrees, -90 degrees, and so forth.
