Answer:

Option C is correct

3x^3-4x^2-10

Step-by-step explanation:

Like terms are those terms which have same variable to the same power.

Find the difference of the following:

(3x^3-2x^2+4)-(2x^2+14)

Remove the parenthesis we get;

3x^3-2x^2+4-2x^2-14

Combine like terms;

3x^3-4x^2-10

Therefore, the difference of (3x^3-2x^2+4)-(2x^2+14) is, 3x^3-4x^2-10

How many "words" can be written using exactly five A's and no more than three B's (and no other letters)?
kakasveta [241]

This is a problem of Permutations. We have 3 cases depending on the number of B's. Since no more than three B's can be used we can use either one, two or three B's at a time.

Case 1: Five A's and One B

Total number of letters = 6

Total number of words possible = \frac{6!}{5!*1!}=6

Case 2: Five A's and Two B's

Total number of letters = 7

Total number of words possible = \frac{7!}{5!*2!}=21

Case 3: Five A's and Three B's

Total number of letters = 8

Total number of words possible = \frac{8!}{5!*3!}=56

Total number of possible words will be the sum of all three cases.

Therefore, the total number of words that can be written using exactly five A's and no more than three B's (and no other letters) are 6 + 21 + 56 = 83

18. Which function is the result of translating y = x^2 downward by 3 units and to the left by 4 units?
algol13

Answer:

C

Step-by-step explanation:

Given f(x) then f(x + k) represents a horizontal translation of f(x)

• If k > 0 then shift left by k units

• If k < 0 then shift right by k units

Here the shift is 4 units to the left, thus

y = (x + 4)²

Given f(x) then f(x) + k represents a vertical translation of f(x)

• If k > 0 then shift up by k units

• If k < 0 then shift down by k units

Here the shift is 3 units down, thus

y = (x + 4)² - 3 → C
