The mass of a 45.750 g piece of copper is measured four times on two different balances with the following results: Trial Balance 1 (g) Balance 2 (g) 1 45.747 45.76 2 45.748 45.74 3 45.744 45.73 4 45.745 45.77 a) Calculate the mean, deviation, % relative deviation, absolute error, and % relative error. Show all Work. b) Which balance is more precise

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
