They intercept in two points.
The graph y=x^2 is very basic so I suppose you know how it looks like.
It's like a U and starts from the origin (0,0)
The graph y=cosx is similar to y=x^2 but in a different way.
y=cosx doesn't pass from (0,0) it passes from (0,1) and then to (-1,0) and (1,0).
Basically, it goes like this..

If you know how the two graphs look like then you can understand why they intercept only two times.

Answer:
The required inequality is .
Step-by-step explanation:
The given inequalities are
where, x is the driver's age (in years), A(x) is driver’s reaction time to audio stimuli and V(x) is his or her reaction time to visual stimuli, 16 ≤ x ≤ 70.
We need to find an inequality that can be use to find the x-values for which A(x) is less than V(x).
Combine like terms.
where, 16 ≤ x ≤ 70.
Therefore, the required inequality is .
The expression that represents well the <em>geometric</em> sequence is and the value of the <em>fourth</em> term is 64. (Correct choice: B)
<em>Geometric</em> sequences are <em>exponential</em> expressions with discrete domain, whose form is presented and explained below:
, where a, r are <em>real</em> numbers and n is a <em>natural</em> number. (1)
Where:
- Value of the starting term.
- Common ratio of the series.
According to the statement, we know that the first term of the <em>geometric</em> sequence is 8 and between any two <em>consecutive</em> terms there is a <em>common</em> ratio of 2. If we know that a = 8, r = 2 and n = 4, then the fourth term of the series by means of (1) is:
f(4) = 8 · 8
f(4) = 64
The expression that represents the <em>geometric</em> sequence is and the value of the <em>fourth</em> term is 64.
