<span>The problem says that the distance D to the horizon is directly proportional to the square root of the elevation E of the observer, so:
</span>
The person who is 36 feet above the water ⇒ √36=6
A person 49 feet above the water ⇒ √49=7
<span>
So, by proportions, you have:
(7/6)x7.4= 8.63 miles
Therefore, the answer is: </span><span>a person 49 feet above the water can see 8.63 miles</span><span> </span>
Answer:
2
Step-by-step explanation:
The answer to number 2 is g.15
Answer:{0,2}
Step-by-step explanation:
Substitute 4x in for the y
2x^2-4x=0
Factor out GCF 2x
2x(x-2)=0
Set each factor = 0 and solve
2x=0 x=0 x-2=0 x=2
It is rational because any number that can be represented in a fraction is rational. 4/33 is a fraction, so it is rational.
