Answer:
hours.
Step-by-step explanation:
We have been given that a chemical spill is leaking into a river flowing 2 3/4 miles per hour.
To find the time taken by chemical to reach the town we will divide distance of town from the spill by distance covered by chemical spill in one hour.
Upon converting our mixed fractions into improper fractions we will get,
Dividing a fraction with another fraction is same as multiplying first fraction by the reciprocal of second fraction.
After cancelling out 4 we will get,
Therefore, it will take the chemicals hours to reach the town.
The function is
The "zeros" of a function, are the values of x, for which f(x)=0
According to the "Rational Root Theorem", the rational roots of f, are factors of 60.
That is, when trying to find the roots of a polynomial function, it is a very good idea to first check the factors of the constant term.
All numbers shown in the choices are factors of 60, so we will solve the problem by trial:
2 is not a root, so we eliminate choices A and D,
Choices B and C are almost equal, with only 1 different number, so let's check whether 5 is a root or not:
but
So the right choice is B
