40 points - answer all parts - you
harold is a woodworker and is interested in finding the density of two different types of wood. he bought a pine log that has a 5-inch radius and is 30 inches long. the weight of the log is approximately 42.63 pounds. he also has an oak board that is 5.5 inches wide, 1.5 inches thick and 3 feet long. the board weighs approximately 8.05 pounds.
part b
what is the density of the pine log? show your work.
part c
what is the density of the oak board? show your work.
part d
if you had a block of each type of wood with the same dimensions, how would their weights compare? explain.
part e
water has a density of about 0.0361 pounds/cubic inch. you might know that wood floats on water. what can you conclude about the densities of objects that float and the densities of objects that do not? review your results from parts b and c before deciding.

the answer will be the last one

step-by-step explanation:

im not sure what the answer is

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
