An article in the local paper is discussing a new copper mine in New Mexico. It states that all that is needed to identify a substance is the mass and volume of a sample. Is this an accurate statement? Why or why not? Yes, because mass and volume are unique properties of a substance. Yes, because mass and volume allows for finding density, which is a unique property of a substance. No, because although mass is a unique property of a substance, volume is not. No, because only density is a unique physical property of a substance and mass and volume are not enough to find it.

to find the unit price of an object, you divide the price by object. you are trying to find out how much an object cost per unit.

for instance, lets say you have 50lb of ice cream(object) that cost 8.00 dollars(price). to find the unit cost, we take the 8.00 and divide it by 50, which will give us .16 cents per pound. we can check this by multiplying .16 by 50 = 8.00

so

object = e2

price = d2

unit price = c2

formula for c2:

=d2 / e2

so in my example about ice cream, we would have the following.

e2 = 50

d2 = 8.00

c2 formula:

=d2 / e2

step-by-step explanation:

which statement is true about the local minimum of the graphed function?

over the interval [–4, –2], the local minimum is 0.

over the interval [–2, –1], the local minimum is 25.

over the interval [–1, 4], the local minimum is 0.

over the interval [4, 7], the local minimum is -7.
