A varies directly as b and a equals 12 when b equals 4 What is the constant of variation?
a varies directly as b and a = 12 when b = 4. What is the constant of variation?
Is y4x a direct variation?
To determine if ( y = kx ) represents a direct variation, ( y ) must vary directly as ( x ) with a constant ratio ( k ). The expression ( y = 4x ) indicates that ( y ) is directly proportional to ( x ) with a constant of variation ( k = 4 ). Thus, yes, ( y = 4x ) is indeed a direct variation.
What is the direct variation formula?
a is directly proportinal or inversely proportional to b
How are direct variation and joint variation related?
Both are variations of certain kinds of equations. X=kY is a direct variation since X varies directly as Y and k is the constant of variation. X=k/Y is an inverse variation where X varies inversly as Y and k is the constant of variation. Both of these variations are also functions.
The area of a circle varies directly as the square of the length of its diameter What is the constant of variation?
pi
What is the central force driving evolution?
Reproductive variation is central to evolution. All else in evolutionary theory follows directly or indirectly from the fact that organisms reproduce with variation.
Is 2x plus 3y equals 0 a direct variation?
Direct variation refers to two variable quantities have a constant (unchanged) ratio, in which a variable "varies directly with the other."In order to have a direct variation, the constant of variation must be not equal to 0 in the equation y=kx, where k is the constant.When you try to put 2x+3y=0 into that formula (y= form), you get:2x+3y=03y=-2x ;Subtract the 2xy=(-2/3)x ;Divide by 3Your constant of variation is -2/3, and since it is less than 0, it is does variate directly. Therefore, y varies directly as x.
What is direct FM generation?
direct fm generation is a method of generation of fm signal directly with the help of parameter variation method. in this method we use some of the devices which converts the variation in voltage to variation in frequency such as varactor diode.
Find an equation of variation where y varies directly as x One pair of values is y equals 80 when x equals 40?
Find an equation of variation where y varies directly as x. One pair of values is y = 80 when x = 40
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 the difference between direct variation and inverse variation?
Direct variation is the ratio of two variable is constant. Inverse variation is when the product of two variable is constant. For example, direct variation is y = kx and indirect variation would be y = k/x .
What is the constant of variation if y varies directly with x and if y equals 500 when x equals 10?
50
