Answer:
The are a is 6
The length of h = 2.4
Step-by-step explanation:
This is a 3 4 5 special triangle so the length of the hypotenuse is 5
The area for a triangle is calculated by multiplying height to the base and that divided by two
Since it's a right triangle we can take any side length as the height and the result wouldn't change
4×3÷2 = 6 is the area for this triangle now we can use thus information to find the length of h :
h × 5 ÷ 2 = 6
5h = 12
h = 2.4
For the first interval (-1, 2), f(-1) = f(2), which means that the average rate of change on that interval is zero, so the correct option is A.
<h3>
Over which interval the rate of change is zero?</h3>
For a function f(x) we define the average rate of change over the interval (a, b) is defined as:
R = (f(b) - f(a))/(b - a)
Here the function is:
f(x) = x^2 - x -1
And the rate of change will be zero on an interval (a, b) if and only if:
f(b) = f(a).
Notice that the first interval is (-1, 2)
f(-1) = (-1)^2 - (-1) - 1 = 1 + 1 - 1 = 1
f(2) = 2^2 - 2 - 1 = 4 - 2 - 1 =1
Then f(-1) = f(2), which means that the average rate of change on that interval is zero, so the correct option is A.

Answer:
A gatekeeper
Step-by-step explanation:
"60 Minutes" is acting as a gatekeeper.
Gatekeeping is a theory in mass communication that involves selecting, and then filtering items of media that can be consumed within the time or space that is allocated to an individual. This means gatekeeping falls into a role of surveillance and monitoring data. Information is filtered for dissemination, for the purpose of publication, broadcasting, the Internet, or some other mode of communication.
