Answer:
Height = 17.31821 feet
Step-by-step explanation:
<u><em>Explanation</em></u>
<u><em>From graph</em></u>
Given angle θ = 6.5° and a = 152 feet
we need to find the height (h)
By using the tangent rule
Cross multiplication , we get
b = 152 × tan 6.5°
b = 152 × 0.113935
b = 17.31821 feet
Height = 17.31821 feet

Answer:
1/2 or 50% of the population has heard the rumor when it is spreading fastest.
Step-by-step explanation:
We need to take the derivative with respect to y from the r(y) = dy/dt = 2y(1-y) and equal to zero. At this condition we maximize the function and will get the maximum of the rumor spreading.
Therefore we just need to find y:
So 1/2 or 50% of the population has heard the rumor when it is spreading fastest.
