A circle is described by the equation x2−10x+y2+8y=6

Mathematics

3 0

x² - 10x + y² + 8y = 6

x² + y² - 10x + 8y - 6 = 0

Center = (-(1/2)A, -(1/2)B)

= (-(1/2)(-10), -(1/2)(8))

= (5, -4)

Radius = √((1/4)A² + (1/4)B² - C)

= √((1/4)(-10)² + (1/4)8² - (-6))

= √((1/4)(100) + (1/4)(64) + 6)

= √(25 + 16 + 6)

= √47

I need to write a problem for this equation 3(2x-5)=24
o-na [289]

Answer:

Three times the difference of two times a number and five is equal to 24, what is x?  

Step-by-step explanation:

To write any equation in word problems, it is important to identify all your parenthesis operations by their technical names. Subtraction is a difference. So since we are multiplying it by 3, it becomes three times a difference.

In the following triangle theta=60.Find the values of the angles of the angles B and B'
Contact [7]

Answer:

180-60 = 120 if triangle is not equilateral it cannot be isosceles then depending where the angles are they will show  60,60,60 if equilateral

For isosceles it would need to be 58 61 61 as 60, 60,60 cannot be isosceles.

Vectors 60 if right angled triangle = 90-60 = 30

So angles = 30 and 90 degree or just 120 if angle theta is a vector as explained below.

Step-by-step explanation:

Statement: If two vectors are represented by the sides of a triangle both in magnitude and direction taken in order, the resultant sum of the vectors is given by the closing third side of the triangle taken in the reverse order both in the magnitude and direction
