Answer: (x + 4)^2 + (y - 3)^2 = 50

Step-by-step explanation:

Given: x^2 + y^2 + 8x - 6y - 25 =0, which the general form of the circle.

Solution:

Complete the square formula: (x - h)^2 + (y - k)^2 = r^2

Group similar term together on the left side of the equation and move the constant to right side of the equation ( remember to change the sign of the constant.

x^2 + y^2 + 8x - 6y - 25 =0

x^2 + 8x + y^2 - 6y = 25

Complete the Square: (x^2 + 8x + _____) + (y^2 - 6y + _____) = 25

Take half of the coefficient of the linear term for each variable, square the quotient, and add the answer to both side of the equation.

half of the coefficient of the linear term: ( 8/2)^2 = 16 and (-6/2)^2 = 9

(x^2 + 8x + 16) + (y^2 - 6y + 9) = 25 + 16 + 9

Each quality is a trinomial square and need to be factored

(x + 4)^2 + (y - 3)^2 = 50

Answer:

a) -4

b) 4

c)0

Step-by-step explanation:

a) It had fallen by 9 ,therefore it would be 5 -9 = -4

b)mode is the most repetitive number that is 4

c) the median is the middle value.First arrange the numbers orderly then get the odd number that is 0.

Answer:

They must sell 43 tickets to raise $500

Step-by-step explanation:

Cost to book the venue = $145

-145 plus 500 (money they need to raise) = $645

Each ticket costs $15

645/15 = 43 tickets

Answer:

I think its 50 okaygdvd dbdur

In a 45 · 45 · 90 triangle, the hypotenuse is √2 · legs, because a 45 · 45 · 90 triangle is isosceles, so the legs are the same length. So, we have 3√2 · √2 = 6, so the hypotenuse is 6.

x=6

Use csc (90) = 10/m.

So, m = 10/csc(90).

m = 8.93997

Answer:

m = 8

Step-by-step explanation:

Here's your solution

=> in traingle DHF and traingle EGF

we have angle DHF and EGF = 90°

and angle F is common , so both traingle are similar by AA similarity

=> 12/m = 15/10

=> m = 120/15

=> m = 8

hope it helps and your day will be full of happiness

Step-by-step explanation:

because the area of square is l² so John is righrt

Answer:

Area of square= ²

Area of square A= ²

Area of square B = ?

let the length of square A = x

Area of square A =x²

then the length of square B = 2x

Area of square B =2x²

x²means area of square A

so Area of square B =2 times area of squarf A

Answer:

25.1cm

Step-by-step explanation:

C=2πr

here radius, r=4 cm and π=3.142

Put values in formula.

C=2(3.142)(4)

C=25.1 cm (Rounded to 1 decimal place)

Answer:

25.1 centimeters

Step-by-step explanation:

Formula to find circumference of a circle is C=2πr

Plug in the given values, 3.142 for π, and 4 for r.

C=2 x 3.142 x 4=25.136 centimeters. Round this to 1 decimal place, so our final answer is 25.1

Answer:

We know that the area of the square of side length L is:

A = L*L = L^2

In this case, we know that the area is:

A = 128*x^3*y^4 cm^2

Then we have:

L^2 = 128*x^3*y^4 cm^2

If we apply the square root to both sides we get:

√(L^2) = √( 128*x^3*y^4 cm^2)

L = √(128)*(√x^3)*(√y^4) cm

Here we can replace:

(√x^3) = x^(3/2)

(√y^4)  = y^(4/2) = y^2

Replacing these two, we get:

L = √(128)*x^(3/2)*y^2 cm

This is the simplest form of L.

Hi there!

[tex]\large\boxed{\text{ sum = 180(n - 2)}}[/tex]

This is the formula for finding the sum of interior angles for a polygon with a number of sides "n".

We can also prove this from the table:

Triangle ⇒ 3 sides: 180(3 - 2) = 180°

Quadrilateral ⇒ 4 sides: 180(4 - 2) = 360°

Pentagon ⇒ 5 sides: 180(5 - 2) = 540°

...And so forth. We can write this as for any polygon with "n" sides:

180(n - 2) = sum (°)

The number of miles that Tatutm walk her dog in 5 days is given by: Option B: 10/3 (in miles)

Let we have to add two fractions as:

[tex]\dfrac{a_1}{b_1} + \dfrac{a_2}{b_2}[/tex]

Then we will find Lowest Common Multiple (LCM) of [tex]b_1[/tex] and  [tex]b_2[/tex]. That will help to make the denominators same.

Once the denominators become same, the numerators can add up directly, giving us the final result of addition.

For this case, we're given that:

For 5 days, the total distance her dog walked = 2/3 + 2/3 + 2/3 + 2/3 + 2/3

Since denominators are same, thus:

[tex]\dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} = \dfrac{2+2+2+2+2}{3} = \dfrac{10}{3}[/tex]

We could've easily done it as: 2/3 + 2/3 + 2/3 + 2/3 + 2/3 = 5 times 2/3 = [tex]5 \times \dfrac{2}{3} = \dfrac{5 \times 2}{3} = \dfrac{10}{3}[/tex]

Thus, the number of miles that Tatutm walk her dog in 5 days is given by: Option B: 10/3 (in miles)
