Answer:

12.6% is the percent of change.

Step-by-step explanation:

As Expo Milano 2015 was visited by 22.2 million people.

And it is expected that Expo 2020 Dubai will be visited by 25 million people.

25 - 22.2 = 2.8 million people

so dividing the 2.8 by 22.2 would give us the percentage of increase.

2.8/22.2 = 0.126 which is = 12.6%

Therefore, 12,6% is the percent of change.

Is x + 10 a factor of the function f(x) = x3 − 75x + 250? Explain.

PtichkaEL [24]

Yes. When the function f(x) = x3 – 75x + 250 is divided by x + 10, the remainder is zero. Therefore, x + 10 is a factor of f(x) = x3 – 75x + 250.

According to the remainder theorem when f(x) is divided by (x+a) the remainder is f(-a).
In this case,
f(x)=x^3-75x+250
(x+a)=(x+10)
Therefore, the remainder f(-a)=f(-10)

=x^3-75x+250
=(-10)^3-(75*-10)+250
=-1000+750+250
=1000-1000
=0.
The remainder is 0. So, (x+10) is a factor of x^3-75x+250.
