8 0

Answer:

  • Option A

Step-by-step explanation:

<u>Find zeros first:</u>

  • x² + x - 6 = x² + 3x - 2x - 6 = x(x + 3) - 2(x + 3) = (x - 2)(x + 3)
  • x = 2, x = -3, x = 7 (but x ≠ 7 as no division by zero)

<u>We have 4 intervals:</u>

  • x ≤ - 3, three negatives, the result is negative or zero
  • -3 ≤ x ≤ 2, two negatives and one positive, the result is positive or zero
  • 2 ≤ x < 7, two positives and one negative, the result is negative or zero
  • x > 7, three positives, the result is positive or zero

<u>The solution is:</u>

  • x ≤ - 3 or 2 ≤ x < 7

Correct choice is A

Answer:

(a) Because it is an exterior angle

(b) The measure of angle 2 is 72°

Step-by-step explanation:

Angle 2 is an exterior angle because it is adjacent to the interior angle 1, and an exterior angle is equal to the sum of the measures of the two nonadjacent interior angles:

<2=30°+42°

<2=72°

How many ways can a person choose 3 desserts from a desserts tray 8 desserts​
skelet666 [1.2K]

In combinatorics, this question is a combination question, because combination deals with selection while permutations deal with arrangement.

nCr =  \frac{n!}{(n - r)!r!} \\

Plugging in our values,

8C3 =  \frac{8!}{(8 - 3)!3!}  =  \frac{8!}{5!3!} = \frac{8 \times 7 \times 6 \times 5!}{5!3!} = \frac{8 \times 7 \times 6}{3 \times 2} = 56 \\

That means 3 desserts from a tray of 8 desserts 56 times.
