PLEASE HELP TIMED ASSIGNMENT PLATO what is the density of the oak board that is 5.5 inches wide, 1.5 inches thick and 3 feet long. show your work.​

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

1/2*qr*rs

step-by-step explanation:

c.

step-by-step explanation:

no oblique asymptote

step-by-step explanation:

to find the oblique asymptote of f(x)

here numerator has degree 1 and denomintor degree 2

degree of numerator < degree of denominator

hence there is no oblique asymptote

when the degree of the denominator > that of the numerator, we saw that the value in the denominator got so much bigger, so quickly,   giving us a horizontal asymptote of the x-axis. or we can write

f(x) = a polynomial of x + a proper fraction.

in this case only we have oblique asymptotes but not when numerator has less degree.
