Sally collected 8 and Jake had 12. Together they had 20.
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.
Answer:
i don't know
Step-by-step explanation:
Answer:
The roots are


Step-by-step explanation:
we have

so
Group terms that contain the same variable, and move the constant to the opposite side of the equation


Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side



Rewrite as perfect squares

square root both sides
