Question

1. the formula v = 1.225√a is used to estimate how far a person can see on a clear day, where v is the visibility in miles and a is the altitude in feet. what is ty’s visibility if he is looking out the upper window of a building with an altitude of 1,602 feet? round your answer to the nearest whole number. v = 40 miles. 40.02499219

Explanation:

Step1: Substitute altitude value

Given $a = 1602$, substitute into $V=1.225\sqrt{a}$. So we have $V = 1.225\sqrt{1602}$.

Step2: Calculate square - root

First, find $\sqrt{1602}\approx40.02499219$.

Step3: Multiply by coefficient

Then, $V=1.225\times40.02499219\approx49.03$.

Step4: Round to nearest whole number

Rounding $49.03$ to the nearest whole number gives $49$.

Answer:

$49$ miles
