A student has one mole of zinc and one mole of oxygen. Which of the following is true for both samples? There are equal masses of zinc and oxygen
There are equal numbers of atoms of zinc and oxygen
There are equal volumes of zinc and oxygen
There are equal densities of zinc and oxygen

you already gave the answer

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

x^3-4x^2+3x-2/x^2+1

step-by-step explanation:

factor the numerator and denominator and cancel the common factors
