What is the constant of variation k if x .5 and y 1 Assume y varies directly as x?
If y varies directly as x then k = 2.
What is half of 2x squared?
Half of 2x squared is x squared. To find half of a term, you divide the coefficient by 2 and keep the variable and exponent the same. In this case, half of 2 is 1, so the expression simplifies to x squared.
If Y is 5 when x is 2.5 and y varies directly with x find y when x is 10?
y varies directly with x means y = kx, where k is the constant of the variation. When x = 2.5 and y = 5, we have y = kx 5 = 2.5k k = 2 When x = 10, y = kx y = (2)(10) y = 20
If a number is subtracted from its square the result is 2. Find the number.?
2. 2 squared = 4, and 4-2 = 2
What is 2x -2 squared?
2x -2 squared = 0
If y varies directly as x squared find k when y equals 16 and x equals -4?
20
If f x varies directly with x2 and f x 96 when x 4 find the value of f 2?
f(2) = 24.
Find an equation of variation where y varies directly as x and y equals 8 when x equals 2 find y when x equals 10?

F x varies directly with x and y equals -2 when x equals 8 Find the constant of variation k?
What is y? Fx varies with x, but y could be anything.
What is the direct variation equation for x3 y2?
y = kx3/2If y2 varies directly with x3, then y varies directly with sqrt(x3) or x3/2.Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. If your question is not answered, please resubmit it, spelling out the symbols as "plus", "minus", "equals" etc. Also use ^ to indicate powers (x^2) or x-squared. :-)
Find an equation of variation where y varies directly as x and y equals 2 when x equals 10 find y when x equals -25?
y = -5
What is the constant of variation k if x .5 and y 1 Assume y varies directly as x?
If y varies directly as x then k = 2.
A right triangle with legs of 7 and 9 units find the length of the hypotenuse?
To find the answer, You Find the square root of 7 Squared (7^2) and add 9 Squared (9^2). So you have Sqrt(7^2+9^2). Works out at about 11.40175

How do you find cosine squared at 30 degrees?
cos(30) = sqrt(3)/2 so cosine squared is 3/4.
How do you find the length of a right triangle with only 2 sides given?
Do the pythagorean theorem. Its A squared plus B squared=C squared. Do that to figure out the other side of the triangle
