Answer:
7.28 miles
Step-by-step explanation:
Suppose the distance at closest approach is represented by x. Then the distance to the point of closest approach at the first sighting is ...
d1 = x·tan(62°)
At the second sighting, the distance to the point of closest approach is ...
d2 = x·tan(38°)
The difference of these distances is 8 miles, so we have ...
d1 -d2 = 8 = x(tan(62°) -tan(38°))
Dividing by the coefficient of x, we find ...
x = 8/(tan(62°) -tan(38°)) ≈ 7.2764 . . . . miles
The point of closest approach is about 7.28 miles from the landmark.

Step-by-step explanation:
Do what? If you mean to find when it equals zero...
By inspection you can see that if x=0 or 2 the expression is equal to zero...
You multiply each term in the parentheses by the term outside the parentheses...like:
3x*3x+3x*6 which is equal to:
9x^2+18x If you meant to expand it....
9x(x+2) If you meant to factor it completely
Step-by-step explanation:
(2(11))^2(8)=22^16
you can use it calculator to finish it up
notice 2s is in brackets before the power sign so U deal with the brackets first
Answer:
2.37 its a rational number because its a decimal
