B varies jointly as u, v, and w
Varies jointly means we have a constant k such that:
B = kuvw
y varies directly as the reciprocal of x
The reciprocal of x is written as:
The phrase varies directly means there exists a constant k such...
Write an equation that relates the quantities. G varies jointly with t and q and inversely with the cube of w . The constant of proportionality is...
r varies directly with s and inversely with the square root of t
Varies directly means we multiply
Varies inversely means we divide
b varies directly as the sum of x and y
This is a direct variation problem.
Direct variation means there exists a constant k such that:
b = k(x...
F varies directly as g and inversely as r^2
Givens and assumptions
We take a constant of variation called k.
Varies directly means we multiply...
z is directly proportional to the square of x and y
Directly proportional means there exists a constant k such that:
z = kx^2y
z varies directly with x and inversely with y
The phrase directly means we multiply.
The phrase inversely means we divide
Variation means there...
does the equation y= x/3 represent a direct variation? If so, state the value of k
Yes, it's a direct variation equation. We rewrite this as:
b varies directly as a. if b is 78 when a is 13, what is b when a is 23?
Using our direct variation calculator, we get:
b = 138
Suppose that h(x) varies directly with x and h(x)=44 when x = 2. What is h(x) when x = 1.5?
Direct variation means we set up an equation:
In a hurricane the wind pressure varies directly as the square of the wind velocity. If a wind pressure is a measure of a hurricane's destruction...
