Let's complete the square. We get:
(x^2-30x)+y^2+221=0
(x^2-30x+225)+y^2+221-225=0
(x-15)^2+y^2-4=0
(x-15)^2+y^2=4
By analyzing this, we see that the radius is just :[tex]\sqrt{4}[/tex]=2
Find the value of the remainder. Enter the value of the remainder (only the number, you do not need to place it over the divisor)
It is simple to locate the rest. Simply divide the number by another number with its multiples to obtain the remaining.
What is a remainder?Always less than the divisor is the remainder. It indicates that the division is not complete if the remainder exceeds the divisor. It might either be higher or lower than the quotient. For instance, the remaining is six when the number seven is divided by 41, leaving five as the quotient.
It's simple to locate the rest of them. To obtain the remainder, we simply divide the number by a different integer that is one of its multiples.
the surplus after division (happens when the first number does not divide exactly by the other). Example: Dividing 19 exactly by 5 is not possible. The closest you can go to 19 without going over is 3 x 5, which is 15 and 4 less. 4 remains as a result.

Which of the following is the solution of the equations: 2x+3y=3, 3x+2y=7
The solution of the equations: 2x+3y=3, 3x+2y=7 is x =0 and y =1.
Equation:
An equation is a mathematical formula containing two algebraic expressions on either side of an equal sign (=). It shows the equivalence relation between the formula written on the left and the formula written on the right. In any formula, L.H.S = R.H.S (left side = right side). We can solve equations to find the values of unknown variables that represent unknown quantities. If a statement doesn't have an equals sign, it means it's not an equation. considered to be an expression.
According to the question:
Given in the question:
2x+3y=3 --------------------------------------- (1)
3x+2y=7 ---------------------------------------- (2)
Multiplying Equation (1) by 3 and (2) by 2, we get:
6x + 9y = 9 --------------------------------- (3)
6x + 4y = 14 --------------------------------- (4)
Now,
Subtracting equation (4) from (3)
5y = 5
⇒ y = 1
Now, putting y = 1 in equation (1) we get:
2x + 3 × 1 = 3
⇒ 2x + 3 = 3
⇒ x = 0
Therefore, x =0 and y=1.

Why is it called substitution method?
It is called the substitution method because we substitute the value of one variable with another one and solve the equation.
By changing the value of another variable in an equation, the variable can be eliminated using this method. Thus, the elimination by substitution method is the name given to this technique.
As we are aware, the substitution approach entails solving the equation to determine the value of the variable, which is then substituted in the other equation. The elimination approach, in contrast, involves removing variables from the equation such that the equation's system can be reduced to being the function of a single variable.

A function's range is the collection of all possible values that it can accept, and its domain is the set of all values for which the function is defined.
A value for x is said to be in the domain of a function f if it successfully allows the production of a single value y using another value for x. The following requirements are frequently verified when a function's output y-value is required to be a real number:
1. The numerator cannot be zero.
2. Even roots (square roots, etc.) radicands (expressions denoted by a radical symbol) cannot have a negative value.
3. Only positive values can be used in logarithms.

A current flows at 5 mph. A boat can travel 20 mi downstream in the same amount of time it can go 12 mi upstream. What is the speed of the boat in still water?
If a current flows at 5 mph. A boat can travel 20 mi downstream in the same amount of time it can go 12 mi upstream. The speed of the boat in still water is 20mph.
How to find the speed?Boat speed x mph
Current speed 5 mph
Against current x - 5 mph
With current x + 5 mph
Distance against current 12
Distance with current 20
Time = same equate the time against with time with current
t=d/r
12 /(x- 5)= 20 /(x+ 5)
12 ×(x+ 5 )= 20 ×(x- 5 )
12 x + 60= 20 x -100
12 x -20 x = -100 + -60

Define the term perimeter of the polygon?The perimeter of an enclosed plane figure is referred to in geometry. The perimeter of an enclosed figure is the sum of the lengths of its outermost sides. It is the sum of the lengths of a polygon's sides. All sides add up to the perimeter.For the shown polygon:
Points A, B, C and D are tangents on the circle.
Thus, these tangent will subtend equal length from the points.
So,
AB = 3 + 4 = 7 cm
BC = 4 + 5 = 9 cm
As, ∠B ≅ ∠D, sides must also be equal.
CD = 5 + 4 = 9 cm
DA = 4 + 3 = 7 cm
Perimeter = AB + BC + BC + BC
= 7 + 9 + 9 + 7
Perimeter = 42 cm
