Write an equation to describe the variation. Use k for the constant of proportionality. V varies jointly with the square root of t and y to the third power
Answers
Answer:Equation for a joint variation is X = KYZ where K is constant. One variable quantity is said to vary jointly as a number of other variable quantities, when it varies directly as their product.
Step-by-step explanation:
Express the following statements as equation of variation using "k" as constant.
1. ) p varies jointly as m and n.
2.) z varies directly as the square of x and inversely as y.
3.) d varies directly as the square root of b and inversely as the cube of c.
4.) C varies jointly as the square of q and inversely as the cube p.
5.) Volume (V) of a circular disc varies jointly as its thickness (t) and the square
of its radius (r).
6.) Volume (V) of a cone varies jointly as its height (h) and
length of the radius (r)
7.) Area (A) of a triangle varies jointly as the height (h) and the length
of the base (b).
8.) Resistance (R) of a wire varies directly with its length (l) and inversely as the
square of its diameter (d)
9.) Kinetic energy (E) of a moving object varies jointly as the mass (m) of the
object and the square of the velocity (v).
10.) Gravitational attraction (G) between two bodies varies jointly as their
masses m and m², and inversely as the square of the distance (d)
between them.
