Tanα=y/x
y=xtanα, we are told that x=25ft and α=30°
y=25tan30° ft
y≈14.43 ft (to nearest hundredth of a foot)
Since their home is 20 feet from the base of the tree, it poses no risk right now.
Answer:
(x - 3)^2 + (y - 6)^2 = 17
Step-by-step explanation:
The standard form of a circle's equation is (x-h)² + (y-k)² = r² where (h,k) is the center and r is the radius.
(x - 3)^2 + (y - 6)^2 = 17

Answer:
14.15m/s
Step-by-step explanation:
\We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 106
(1500 miles ÷ 106) / (106 seconds ÷ 106)
=14.15 miles/ 1 second
=14.15 miles/second
= 14.15 miles per second
The Answer: (-b + 15) (15 - b)
