Athird-degree polynomial function f has real zeros -2, 1⁄2, and 3, and its leading coefficient negative. write an equation for f. sketch the graph of f. how many different polynomials functions are possible for f?

f(x) = -x³ + (3/2)x² + (11/3)x + 3.

Step-by-step explanation:

Given, real zeroes of f(x) are -2, 1/2, 3.

⇒ f(x)  = -(x+2)(x-1/2)(x-3). (- sign because given leading coefficient is negative)

⇒f(x) = -x³ + (3/2)x² + (11/3)x + 3.

as the real zeroes are fixed, only one such polynomial is possible.

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
