The lowest time interval for which it is guaranteed that A(t) = 400 is 70 ≤ t ≤ 90.
<h3>What is Intermediate value theorem?</h3>
- The intermediate value theorem in mathematics states that any value between f(a) and f(b) at some point within the interval can be assigned to f if it is a continuous function whose domain contains the interval [a, b].
- This theorem is used to demonstrate that a point can exist below or above a specific line. It can also be used to determine if a function is continuous or not by analyzing its continuity.
<h3>Calculation of time interval:</h3>
Because, A is diffrentiable, A, is continuous.
A(70) = 250<400<405 = A(90)
By the Intermediate Value Theorem, there must be at least one time t, for 70 ≤ t ≤ 90, such that A(t) =400.
Hence, the shortest time interval during which it is guaranteed that A(t)=400 is 70 ≤ t ≤ 90.

Answer: c
explanation: because the rest just make sense
The answer is car it is right I know it
The answer is that it <span>illustrates most clearly the defense mechanism of reaction formation.
Reaction Formation happens when a man wants to do or say something and afterward really does or says something that is viably the opposite they truly need.A reason for Reaction Formation is the point at which a man looks to conceal something unsatisfactory by embracing an inverse position.
