Answer:

Step-by-step explanation:

The equation of the circle that passes through the point (-2 , 3) and has a center at the origin is x^2 + y^2 = 13.

Using the distance formula, get the radius of the circle by solving for the distance between the center and the point (-2 , 3).

radius = distance = √(x2 - x1)^2 + (y2 - y1)^2

radius = √(-2 - 0)^2 + (3 - 0)^2

radius= √4 + 9

radius = √13

The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.

Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.

(x - h)^2 + (y - k)^2 = r^2

where (h , k) = (0 , 0)

r = √13

(x - 0)^2 + (y - 0)^2 = (√13)^2

x^2 + y^2 = 13

Step-by-step explanation:

An isosceles triangle is one with two equal-length sides. ΔABC is an isosceles triangle.

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

D = √[(x-p)² + (y-q)²] units.

Given that the coordinates of the vertices of the triangle are A(0,0), B(a, b), and C(2a, 0). Now, to prove that the given triangle is an isosceles triangle we need to find the length of each side of the triangle.

AB = √[(x₂-x₁)² + (y₂-y₁)²]

     = √[(a - 0)² + (b - 0)²]

     = √(a² + b²)

BC = √[(x₂-x₁)² + (y₂-y₁)²]

     = √[(2a - a)² + (0 - b)²]

     = √(a² + b²)

AC = √[(x₂-x₁)² + (y₂-y₁)²]

     = √[(2a - 0)² + (0 - 0)²]

     = √4a²

     = 2a

Since the length AB and BC are the same, while the length of AC is different, therefore, ΔABC is an isosceles triangle.

In 8 months he will have a total of 44 books in his collection.

The correct answer is an option (H)

In this question,

Paul collects comic books. He has 20 books in his collection, and he adds 3 per month.

We need to find the number of months required to have a total of 44 books in his collection.

Let n be the required number of months.

From given information, we get an equation,

20 + 3n = 44

We solve above equation to find the required number of months.

20 + 3n - 20 = 44 - 20

3n = 24

n = 8

Therefore, in 8 months he will have a total of 44 books in his collection.

The volume of the larger tent in the shape of hemispheres, with circular floors, is 89.8 cubic feet.

If the diameter of the smaller tent is 6 feet, then its radius is 3 feet. Solving for the area of its circular floor,

A = πr^2

A = π(3 feet)^2

A = 9π square feet

Using the ratio of the floor areas of the two tents, calculate the area of the circular floor of the larger tent.

9 : 12.25 = 9π square feet : x

where x = area of the circular floor of the larger tent

9x = 12.25(9π)

x = 12.25 π square feet

If the area of the circular floor of the larger tent is 12.25 π square feet, then solving for its radius,

A = πr^2

12.25 π square feet = πr^2

r = 3.5 feet

Hemisphere refers to half of a sphere and its volume is given by the formula V = 2/3πr^3, where r is the radius.

V = 2/3πr^3

V = 2/3 π (3.5 feet)^3
