Answer:
You would need 2.5
Step-by-step explanation:
You can use a porportion to solve.
(cross multiply and solve)

Let denote the amount of salt in the tank at time
. We're told that
.
For , the salt flows in at a rate of (1/5 lb/gal)*(5 gal/min) = 1 lb/min. When the regulating mechanism fails, 20 lbs of salt is dumped and no more salt flows for
. We can capture this in terms of the unit step function
and Dirac delta function
as
(in lb/min)
The salt from the mixed solution flows out at a rate of
Then the amount of salt in the tank at time changes according to
Let denote the Laplace transform of
,
. Take the transform of both sides to get
Solve for , then take the inverse of both sides.
The complete factor of the polynomial 625x⁸ − 1 is (25x⁴ + 1)(25x⁴ − 1). Then the correct option is A.
<h3>What is polynomial?</h3>Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
Factor completely 625x⁸ − 1.
We know that
(25x⁴)² − 1²
(25x⁴ + 1)(25x⁴ − 1)
The complete factor of the polynomial 625x⁸ − 1 is (25x⁴ + 1)(25x⁴ − 1). Then the correct option is A.
