If the tower is located at the origin, the equation of its circular area of coverage is [tex]x^{2} +y^{2} = 225[/tex]

A circle is a closed curve that is drawn from a fixed point. This point is called the center. All points on the curve are equidistant from this center point.

The equation of a circle with center at (h, k) and radius r is given by:

[tex](x - h)^{2} + (y-k)^{2} = r^{2}[/tex]

According to the given condition,

center is origin i.e., (h, k) is (0,0)

and r = 15.

Substituting these values in the equation above,  

[tex](x - 0)^{2} + (y-0)^{2} = 15^{2}[/tex]

[tex]x^{2} + y^{2} = 225[/tex]

Thus, the equation of the tower located at origin and having coverage area of radius 15 miles is  [tex]x^{2} + y^{2} = 225[/tex].

Answer:

14

Step-by-step explanation:

That equation, with the given constraints, is easily solved using logical reasoning.10y is a multiple of 5, and 25 is a multiple of 5; that means 7x is a multiple of 5.And we know x is a number between 10 and 20. So x has to be 14

The coordinates of the midpoint of a segment with the given endpoints will be (8, 9.5).

Let AB be the line segment and C be the mid-point of line segment AB. Let the coordinate of point A (x₁, y₁), the coordinate of point B (x₂, y₂), and the coordinate of the mid-point (x, y).

Then the coordinate of the mid-point of the line segment is given as,

(x, y) = [(x₁ + x₂) / 2, (y₁ + y₂) / 2]

The endpoints are A(13, 14) and C(3, 5).

Then the coordinates of the midpoint of a segment with the given endpoints will be

(x, y) = [(13 + 3) / 2, (14 + 5) / 2]

(x, y) = (16/2, 19/2)

(x, y) = (8, 9.5)

The coordinates of the midpoint of a segment with the given endpoints will be (8, 9.5).

The measure of angles ∠1, ∠2, ∠3, ∠4, ∠5, ∠6, ∠7, and ∠8 will be 40°, 140°, 40°, 140°, 40°, 140°, 40°, and 140°, respectively.

The angle is the separation of the crossing surfaces or lines. Additionally, the angle is specified in degrees. One whole spin has an arc of 360 degrees.

If the total of two angles is 180 degrees, they are said to be supplementary angles.

In the third line, if two lines are parallel. Equal angles are formed by matching angles.

When two lines intersect, then their opposite angles are equal.

The measure of angle ∠1 is 40°.

Angle ∠1 and angle ∠2 are supplementary angles. Then the measure of angle ∠2 will be

∠1 + ∠2 = 180°

40° + ∠2 = 180°

∠2 = 140°

The vertical angles are given below.

∠1 = ∠3 = 40°

∠2 = ∠4 = 140°

The sum of three angles of a triangle is 180° .

Given two angles of a triangle are 85° and 63°. We need to find the third angle at 24.

The angle at 24 be x.

By angle sum property,sum of three angles of a triangle is 180°.

The two angles are  85° and 63° and third angle is x.

85°+63°+x=180°

148°+x=180°

x=180°-148°

Answer:

Center: (2,2)

Radius: 2

Answers:

Center = (2,2)

Radius = 2

=================================================

Explanation:

Consider (A+B)^2 = A^2+2AB+B^2 after using the FOIL rule.

If A = x, then we have (x+B)^2 = x^2+2Bx+B^2

The coefficient of the x term is 2B. It divides in half to get B, and it squares to B^2 as the final term.

In short, if we want to complete the square on something like x^2-4x, then we do two things:

So we go from -4 to -2 after dividing in half, and then from -2 to 4 after squaring. We'll add 4 to both sides to complete the square for the x terms.

[tex]x^2+y^2-4x-4y+4 = 0\\\\(x^2-4x)+(y^2-4y)+4 = 0\\\\(x^2-4x+4)+(y^2-4y)+4 = 4\\\\(x-2)^2+(y^2-4y)+4 = 4\\\\[/tex]

We'll do the same thing for the y terms. Though notice we already have a +4 on the left side. So we can have it absorb into the y terms parenthesis grouping like so

[tex](x-2)^2+(y^2-4y)+4 = 4\\\\(x-2)^2+(y^2-4y+4) = 4\\\\(x-2)^2+(y-2)^2 = 4\\\\[/tex]

Now compare that to the circle template

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

We see that

This circle has its center at (h,k) = (2,2)

The radius is r = 2

Answer:

 $3500

Step-by-step explanation:

x = value of diamond with an increase of 5% every year for 8 years

x= 2500(0.05)

x= 125(8)

x = 1000

2500 + 1000 = $3500

The value of the diamond after 8 years is the amount of $3693.63.

Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.

To find the value of the diamond after 8 years, we need to calculate the compound interest.

The formula for compound interest is:

A = P(1+r/100)ⁿ

here:

A = final amount

P = principal amount

r = annual interest rate (as a decimal)

t = time in years

Using this formula, we can calculate the value of the diamond after 8 years:

P = 2500

r = 5% = 0.05

t = 8

A = 2500 (1 + 0.05/1)¹ˣ⁸

A = 2500 (1.05)⁸

A = 2500 (1.4775)

A = $3693.63

Therefore, the value of the diamond after 8 years is $3693.63.

The measure of the vertex angle is 92°

Here,

The triangle is isosceles and one base angle of an isosceles triangle has a measure of 44°

We have to find the measure of the vertex angle.

What is Isosceles triangle?

A triangle is said to be isosceles if there is any two corresponding sides are equal and there angle are equal.

Now,

The triangle is isosceles triangle.

Hence, there corresponding sides and there angles are equal.

So, Both base angles of a triangle are equal.

And, Sum of angles of a triangle are 180°

Let the measure of the vertex angle is x°

Hence,

⇒ 44° + 44° + x° = 180°

⇒ x° = 180° - 88°

⇒ x° = 92°

Therefore, The measure of the vertex angle is 92°

The equation of line is:

y = (5/2) x - 11

Given,

Points (x₁, y₁) = (-12, -6) and (x₂, y₂) = (8, 9)

We can find the slope using the equation for slope

m = (y₂ - y₁) / (x₂ - x₁)

   = (9 -(-6)) / (8-(-12))

   = (9+6) / (8 + 12)

    = 15/20 = 3/4

We know the slope and a point, so we can use point slope form to make an equation

y-y₁ = m(x-x₁)

y - (-6) = 3/4 (x-(-12))

Distribute

y+6 = 3/4x – 3/4 × 2

y+6 = 3/4x - 3/2

Add -6 to each side

y + 6 -6 = 3/4x - (3/2)-6

y = 3/4x - (-9/2)

y = 3/4x + 9/2

A triangle with vertices located at A(1 , 1), B(2 , 5), and C(5 , 1) has a perimeter of 13.1 units.

A triangle is a two-dimensional shape that has three sides or edges and three vertices.

Perimeter refers to the distance around any two-dimensional shape. The perimeter of a triangle is the sum of the length of its sides.

To solve for the perimeter of triangle ABC with vertices located at A(1 , 1), B(2 , 5), and C(5 , 1), solve first for the length of each side, namely side AB, side BC, and side AC.

And to solve for the length of each side, use the distance formula given by:

d = √(x2 - x1)^2 + (y2-y1)^2

side AB : d = √(2 - 1)^2 + (5 - 1)^2 = √1 + 16 = √17 units

side BC : d = √(5 - 2)^2 + (1 - 5)^2 = √9 + 16 = √25 = 5 units

side AC : d = √(5 - 1)^2 + (1 - 1)^2 =√16 + 0 = √16 = 4 units
