A larger and brand new CT scanner can run as high as $2.5 million. Prices are slightly higher for MRI machines, running up to about $3 million for a new machine.
1. constant of proportionality-the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality. factor of proportionality.
Any polynomial written in standard form has a unique constant term, which can be considered a coefficient of x 0. In particular, the constant term will always be the lowest degree term of the polynomial.This also applies to multivariate polynomials.as a constant term of â4, which can be considered to be the coefficient of x 0 y 0, where the variables are become eliminated by exponentiated to 0 (any number exponentiated to 0 becomes 1).
