You are given five integers and your task is to find the smallest of them
Vikentia [17]

The minimum number of comparisons to find the smallest number from 5 integers is 4.

<h3>How to find the Smallest Integer?</h3>

Let the five numbers be a,b,c,d and e.

Let s be an integer

Comparison 1:

a and b will be compared first and the smaller number of them will be equal to s

Comparison 2:

Now, a smaller number between a and b that is s will be compared with c. Similarly, the smaller number of both numbers will be taken as s in the next comparison.

Comparison 3:

Likewise, s and d will be compared and a smaller number will be taken as s for the next comparison

Comparison 4:

Likewise, s and e will be compared and a smaller number will be taken as s for the next comparison.

After 4th comparison, s will be equal to smallest number of 5 integers.

Thus;

Total comparisons = 4

Therefore, the minimum number of comparisons to find the smallest number from 5 integers is 4.

A 10-foot tree casts a 17-foot shadow directly down a slope when the angle of elevation of the sun is 42o (see figure). Find \th
inna [77]

The angle of elevation of the ground is the angle between the ground and the line of sight

The angle of elevation of the ground is 30.46 degrees

<h3>How to calculate the angle of elevation</h3>

The angle of elevation is calculated using the following tangent ratio

\tan(\theta) = \frac{10}{17}

Evaluate the quotient

\tan(\theta) = 0.5882

Take the arc tan of both sides

\theta = \tan^{-1}(0.5882)

Using a calculator, we have:

\theta = 30.46

Hence, the angle of elevation of the ground to the nearest tenth of a degree is 30.46 degrees
