If y varies inversely as the square of x and y equals 4 when x equals 5 find y when x is 2?

If y varies directly with x and y equals 10 when x equals 5 what is the value of k?
We write y=kx since y varies directly as x. Now we know if x is 5, y is 10. so we write 10=5k so k=2
If y varies inversely as the square of x and y equals 4 when x equals 5 findy y when x is 2?
y varies inversely as x2 so y = c/x2 for some constant c. When x = 5, y = 4 So c = x2y = 100 that is y = 100/x2 Then, when x = 2, y = 100/4 = 25
Complete the equation of variation where y varies inversely as x and y equals 4 when x equals 2?
xy = 8 or y = 8/x
Assume that y varies inversely with x and that y is 2 when x is 4 what is the equation of inverse variation?
2=8/4 the constant is 8 y-k/x i think.
If y varies directly as x what is the value of y in these ordered pair 8 4 and 4 y?
It is 2.
X varies directly with y and inversely with z x equals 20 when y equals 8 and z equals 4 Find x when y equals 4 and z equals 8?
The answer is x=10. If: x=20 y=8 z=4 then: y=8/2=4 z=4*2=8 since x varies directly with y, meaning whatever happens to y, happens to x, so if y was divided by 2, then x should be divided by 2. After all, the inverse of division is multiplication.
If f x varies directly with x2 and f x 96 when x 4 find the value of f 2?
f(2) = 24.
If y varies directly as x and y is 6 when x is 72 what is the value of y when x is 8?
y is 2/3.
X varies directly with y and inversely with z x equals 0.12 when y equals 12 and z equals 2 Find x when y equals 1200 and z equals 1?
x = 24
Complete the equation of variation where y varies inversely as x and y equals 80 when x equals 0.7?

If y varies directly as x squared find k when x 2 and y 8?
If y varies directly as x and if x = 2 when y = 8 then k = 4.
If y varies inversely as the square of x and y equals 4 when x equals 5 find y when x is 2?

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.
If y varies directly with x and y equals 10 when x equals 5 what is the value of k?
We write y=kx since y varies directly as x. Now we know if x is 5, y is 10. so we write 10=5k so k=2
When the length is increased 2 times the value for resistivity will be?
The value for resistivity will remain unchanged (provided temperature remains constant). Resistivity is a property of the material. The resistance, however, will double. Remember that resistance is directly proportianal to the length of the conductor and inversely proportional to the cross-sectional area of the conductor.
