Question choices:<br> A: I, IV<br><br> B: II, III, IV<br><br> C: III, IV<br><br> D: II, III
gulaghasi [49]

0Answer:

A

Step-by-step explanation:

Find the zeros by letting y = 0 , that is

x² - x - 6 = 0 ← in standard form

(x - 3)(x + 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x + 2 = 0 ⇒ x = - 2

Since the coefficient of the x² term (a) > 0

Then the graph opens upwards and will be positive to the left of x = - 2 and to the right of x = 3 , that is in the intervals

(-∞, - 2) and (3, ∞ ) → option A

Llana [10]

Answer:

<u>20,602 feet</u> is the difference in height between the top of Mt. McKinley and the bottom of the Death Valley.

Step-by-step explanation:

Given:

Mt. McKinley, which is the highest elevation in North America, is 20,320 feet above sea level.

Death Valley, which is the lowest elevation in North America, is 282 feet below sea level.

Now, to find the difference in height between the top of Mt. McKinley and the bottom of the death valley.

<em>Height of Mt. McKinley above sea level = 20,320 feet.</em>

<em>Height of Death Valley below sea level = 282 feet.</em>

Now, to get the difference in height between the top of Mt. McKinley and the bottom of the Death Valley by adding both the heights:

20320+282

=20602\ feet.

Therefore, 20,602 feet is the difference in height between the top of Mt. McKinley and the bottom of the Death Valley.
