Answer:
The conclusion is that the robber is fast.
Step-by-step explanation:
The first assertion is that if the robber is fast, the police can't catch him. The next information that you get is that they indeed <em>can't </em>catch him, showing that this is the answer.

Answer:
6
Step-by-step explanation:
I used a calculator and the answer is 6
The given polynomial expressed as partial fraction is 5x^3 + 9/x
<h3>Polynomial function and partial fractions</h3>
Polynomial function are function that have a leading degree of 3. Given the expression below;
f(x) = (5x^4+9)/x
Applying partial fraction
Since the part fraction means separating the fraction into two parts, hence;
f(x) = 5x^4/x + 9/x
Simplify
Since there is value of x at both numerator and denominator, it will cancel out to have
f(x) = 5x^3 + 9/x
From the result, we can see that p(x) = 5x^3 and k = 9
Hence the given polynomial expressed as partial fraction is 5x^3 + 9/x
