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.

#SPJ4
The answer is A or C because 10 countries share the water from the nile river. and they are all currently in drought to over pumping of water from the soil.
Answer:
No
Explanation:
A lot of dependency brings about loses and debt, because the country which is being depended on will request for something in exchange and when it comes to financial aspect the borrowed money given will be increased as profit to the countries being depended upon..
I think it’s C. If not I’m sorry
