What is the minimum value of the sum of their squares if the sum of two numbers is K?

So to start off, set each number equal to a variable. (In this case, I will use x= 1st number and y= 2nd number) Since the sum of the two numbers is K... x+y=K Therefore y=K-x And the sum of their squares is a minimum... x^2+y^2=MINIMUM Therefore = x^2+(K-x)^2 So to simplify... ( Full Answer )

How do you get the square root of a perfect square?

you find what same 2 numbers equal that number EXAMPLE: what is the square root of 49? ANSWER:7 because 7x7=49 Edit: Nearly there. 7 is the PRINCIPAL square root but there is another, which is -7. (-7)*(-7) is also 49.

How do you get the square root of not perfect square?

One way is to solve the equation x^2 - number = 0 with Newton's method. Start with a guess for the answer (say your number is 20, guess 5 or something - it hardly matters how bad your guess is). Say your guess is G. Then compute : 0.5 * (G + 20/G) This will give you a new guess. Rinse and repe ( Full Answer )

What is cube root and square root?

A square root of a number is a number that, multiplied by itself once, will equal the first number. Meanwhile a cube root of a number is a number that, multiplied by itself twice, will equal the first number.. For example: the square root of 4 is 2. [ 2 X 2 = 4 ] [ 2 times itself equals 4 ]. the c ( Full Answer )

What is the root of a perfect square?

The root of a perfect square will be an integer, but will be both the positive and negative values. For instance, the square root of 4 is plus or minus 2 (±2), as both integral answers are valid.. The positive real root is the answer that many books give. It is sometimes called the primary roo ( Full Answer )

What is perfect square root?

A perfect square root is where the square root of a number equals another whole number. For example, the square root of 144 is 12. 12 is a whole number thus 144 is a perfect square root.

What is perfect square and perfect cube?

The square root of a perfect square and the cube root of a perfect cube is always an integer. A perfect square is a number multiplied by itself. A perfect cube is a number multiplied by itself twice. Example: 3 x 3 is 9, the square of 3 3 x 3 x 3 is 27, the cube of 3

What is 280 K in Fahrenheit?

To convert from degrees Kelvin to degrees Fahrenheit, firstly subtract 273.15, to turn into degrees Celsius, then multiply by 9, divide by 5, and add 32. In this instance: 280 - 273.15 = 6.85 x 9 = 61.65 / 5 = 12.33 + 32 = 44.33 Therefore, 280 degrees Kelvin is equal to 44.33 degrees Fahrenheit.

What is the smallest value of k when 882k is a cube?

Factor the number 882, until you get prime factors. See what prime factors are missing to complete a cube (each prime number has to be to the power 3, 6, etc.). Multiply those missing factors, to get "k".\n

How do you find the value of k when the line y equals x - 3 touches the curve x squared - 3y squared equals k?

Equation 1: y = x-3 => y 2 = 3y 2 -18x+27 when both sides are squared and multiplied by 3 Equation 2: x 2 -3y 2 = k => x 2 -k = 3y 2 => 3y 2 = x 2 -k By definition: 3x 2 -18x+27 = x 2 -k => 2x 2 -18x+27+k = 0 Use the discriminant b 2 -4ac = 0 to find the value of k: b 2 -4ac = 0 => 18 2 -4 ( Full Answer )

What are the range of values of k when y equals 2x plus k and x squared plus y squared equals 4 but do not intersect?

Equation 1: y = 2x+k => y 2 = 4x 2 +4kx+k 2 when both sides are squared Equation 2: x 2 +y 2 = 4 => y 2 = 4-x 2 when rearranged So by definition: 4x 2 +4kx+k 2 = 4-x 2 => 5x 2 +4kx+k 2 -4 = 0 If the values are tangent to the curve then the discriminant b 2 -4ac = 0 b 2 -4ac = 0 => 16k 2 ( Full Answer )
