Answer:

A C

Step-by-step explanation:

A

A is true.The numerator does have 3 terms. The constant term (the 3 at the end) is still a term and counts as a term.

B

A constant term does not count as a coefficient so b is not right, just as you have indicated by not underlining it.

C

C is true. In fact, 2 is the leading coefficent of the denominator.

D

Either A is true or D is, but I don't think they both are. You need a modifier to claim that D is true. If the statement said the numerator has <em>at least </em>2 terms then both A and D would be true. Without the at least, you have to pick one and the one I choose is A

E

This is the tough one. Very sticky. You would think it is true, but it isn't. A constant term is not a coefficient. Coefficients only count when they are with "x"s.

Answer:

  • The numerator has 3 terms.
  • The denominator includes a coefficient of 2.

and possibly (check your definitions)

  • The denominator includes a coefficient of 4.
  • The numerator includes a coefficient of 3.

Step-by-step explanation:

Apparently, the exercise is to count terms and identify coefficients.

A term is a constant or the product of a constant and some constellation of variables.

A coefficient is a multiplier of the variable(s) of interest. Any term or expression multiplying only 1 (not any expression involving the variable(s) of interest), may be called a "constant coefficient."

Consider the expression ...

... axy +bx +cy +d

If we consider the variables x and y to be the variables of interest, then "d" is a "constant coefficient" and "a", "b", and "c" are the coefficients in the first three terms.

If we consider y to be the variable of interest, then "ax" and "c" are coefficients (or you could say (ax+c) is the coefficient of y) and (bx+d) is the "constant coefficient."

<em>Your Mileage May Vary</em>

Other sources identify a coefficient as the multiplier of variables. Those sources would ignore any constants or other expressions that don't multiply variables of interest. Check your reference text to see how it defines <em>coefficient</em>.

<em>Comment on your answer choices</em>

You have selected contradictory answers: the numerator term count is 3; the numerator term count is 2. (The <em>denominator</em> term count is 2, but that is not on the list.)

point a has the coordinates(2,5) point B has the coordinates (6,17) how long is segment ab in simplified radical form
IRISSAK [1]

Answer:

4\sqrt{10}

Step-by-step explanation:

We have been given that point A has the coordinates(2,5) point B has the coordinates (6,17).

To find the length of segment AB we will use distance formula.

\text{Distance}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Upon substituting coordinates of point A and point B in distance formula we will get,

\text{Distance between point A and point B}=\sqrt{(6-2)^2+(17-5)^2}

\text{Distance between point A and point B}=\sqrt{(4)^2+(12)^2}

\text{Distance between point A and point B}=\sqrt{16+144}

\text{Distance between point A and point B}=\sqrt{160}

\text{Distance between point A and point B}=4\sqrt{10}

Therefore, the length of segment AB is 4\sqrt{10}.

A quantity with an initial value of 8600 grows exponentially at a rate of 20% every 2 minutes. What is the value of the quantity
Hatshy [7]

Answer:

23400 x 8/100 = 1872 = the loss  

1872 : 12 = 156= the loss each month  

156/1872*100% = 8.33 % then round it
