This problem is solely on right triangles, wherein the Pythagorean theorem may be applied. We must first find the angle of elevation of the flagpole using Tim's height and the difference between the shadow of the flagpole and Tim's distance from the flagpole. Therefore tan a = 1.65/(16.6-12.5) where a=21.68 degrees. We use this angle to determine the height of the flagpole. tan 21.68 = x/ 16.6 where x=height of flagpole=6.6 meters.
She drove 9 miles over the speed limit.
94.50 + 2m = 112.50
Subtract 94.50 from both sides
2m = 18
Divide both sides by 2
m = 9

Thats it.................
Answer:
The other zero is also a rational number.
Step-by-step explanation:
In a quadratic equation
Quadratic formula:
Case 1: If 
, then the given quadratic equation has two distinct real zeros.
Case 2: If 
, then the given quadratic equation has exactly one real zero.
Case 3: If 
, then the given quadratic equation has two distinct complex zeros.
It is given that the quadratic has 2 distinct zeros. One of the zeros is rational.
It means
and 
is a rational number.
Therefore, the other zero is also a rational number.
