Answer:
512 in³
Step-by-step explanation:
The height perpendicular to the base is the leg of a right triangle with hypotenuse 10 in and other leg 8 in. Using the Pythagorean theorem, we can find it as ...
h² +8² = 10²
h² = 100 -64 . . . . . subtract 8²
h = 6 . . . . . . . . . . . . take the square root of 36
Then the volume is found using ...
V = (1/3)Bh = (1/3)(16 in)²(6 in) = 512 in³
The volume is 512 cubic inches.
_____
The 8-inch dimension used above comes from half the distance between the center of one side of the base to the center of the opposite side. (16 in)/2 = 8 in.

Answer:
D
Step-by-step explanation:
Terms are separated by addition and subtraction symbols.
Polynomials consist of terms that are constant and/or variable. The variable terms must have 0 or positive exponents. Polynomials will not consist of division of variable expressions.
Examples of polynomials:




Examples of non-polynomials:


In general a polynomial when written in standard form should be comparable to:

where the
's could be zero and all the exponents,n, are positive or 0.
D is comparable since all of these are 0 except
which is 1 and
which is -2.
Also the other choices have either division by variable expressions and/or negative exponents on variables.
