The center of a circle of the form:
is (a, b) and its radius is r.
Comparing the given equation of circle we can write:
a = 20
b = 0.05
r² = 81
This means the center of the circle is (20, 0.05) and the radius of the circle is 9.
Answer:
tree is about 18.82 ft high
Step-by-step explanation:
The triangles (that are formed by the tree and the poll with their shadows and the line from top to the end of the shadow) are in proportion because they cast the shadow at the same time.
x/9 = 23/11 , we write the proportions
x = 23*9 / 11, multiply both sides by 9
x ≈ 18.82 ft.
