Answer:
256 train or 80% of the trains arrived on time
Step-by-step explanation:
Total trains that arrived in a week = 320 trains
Late = 5% of 320
early = 15% of 320
On time = 320 - (15 + 5% of 320)
=> 320 - (20% * 320)
=> 320 - 64
=> 256
Therefore, 256 train or 80% of the trains arrived on time
Hope my answer helps :)
By factor theorem (v+5) is not a factor of the given polynomial f(v).
What does factor theorem mean?
When thoroughly factoring the polynomials, mathematicians apply the factor theorem. The polynomial's zeros and factors are connected by this theorem.
The factor theorem states that if a is any real number and f(x) is a polynomial of degree n 1 then (x-a) is a factor of f(x) if f(a)=0.
The factor theorem states that
f(x) has a factor (x-k) if and only if f(k) = 0
We are given the following information.
F(v) = v 4 + 16v 3 + 8v 2 - 725
We have to check whether (v+5) is a factor of given polynomial.
( v + 5 ) = ( v - ( - 5 )
f( -5 ) = 
= - 1900
f(-5) ≠ 0

Answer:
In mathematics, an inverse function (or anti-function) is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, i.e., f(x) = y if and only if g(y) = x.

Answer:
12.50
Step-by-step explanation:
4.52 is roundes to 4.50. Then, 7.99 is rounded to 8. Thus, 4.50 + 8 = 12.50
