Answer:
Step-by-step explanation:
Given is a function
This function is a parabola with vertex at (2,0) and axis of symmetry is x=2
Hence for x<2 the curve would be reflection of x>2
To get inverse we must get one to one funciton only.
So restrict the domain of f(x) to
Then we have f(x) as one to one with domain x≥2 and range is R+
For this inverse domain is R+ and range is
Answer:
85,910
You get this because whenever there are three digits after a number you add a comma as seen in the number there are three digits after 85 so you add a comma.
Hope it helps bai!
Answer:
272.17 ft
Step-by-step explanation:
Since the angle of depression of the sighting equals the angle of elevation of the lighthouse from the boat, using trigonometric ratios,
tanθ = x/d where θ = angle of sighting, x = height of lighthouse =55 ft and d = distance of boat from lighthouse at sighting
So, d = x/tanθ
when θ = 8.1°, for the first sighting,
d₁ = 55/tan8.1 = 386.45 ft
when θ = 25.7°, for the second sighting,
d₂ = 55/tan8.1 = 114.28 ft
The distance the boat traveled between the two sightings is thus d₁ - d₂ = 386.45 ft - 114.28 ft = 272.17 ft
Yes I believe they are 1 to 15. If I'm not wrong please dont report me.
