Answer:
0. Domain=(0,5)
,
1. Range=(0,60)
Explanation:
From the graph
The point on the graph starts at (0,0) and ends at (5,60).
The domain of the function is the set of all the values of x in the function.
Therefore:
The range of the function is the set of all the values of y in the function.
Therefore:
Answer:
y=1/2x-7
Step-by-step explanation:
Answer:
15 m
explanation:
Let AB and CD be the pole and tower respectively. Let CD=h Then ∠DAC=60 ∘ and∠DBE=30 ∘ Now CA CD =tan60 ∘ = 3 ∴CD= 3 CA⇒ 3 h =CA Again BE DE =tan30 ∘ = 3 h ∴(h−10)= 3 BE = 3 CA ...[∵BE=CA] = 3 h/ 3 = 3 h ⇒3h−30=h⇒2h=30⇒h=15
Hence, height of the power =15 m
