A polynominak function has a root of -6 with a multiplicity 1, a root if -2 with a multiplicity of 3, a root if 0 with a multiplicity of 2, a root if 4 with a multiplicity of 3. if the function has a posative leading coefficient and is of odd degree, which statement about the graph is true? a. the graph of the function is positive on (-6,-2)
b the graph of the function is negative on (-infinity symbol, 0)
c. the graph of the function is positive on (-2,4)
d. the graph of the function is negative on (4, infinity symbol).

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.

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.

step-by-step explanation:

answer: 12/52

step-by-step explanation: my reasoning is that there are 12 face cards in a deck and a total of 52 cards in all.
