Step-by-step explanation:
Given
Required
Determine the distance covered in 98 seconds
To solve this, the following assumption must be made:
- <em>The peacock walks at a constant speed</em>
So, first we calculate the speed
Substitute 6 for Distance and 15 for Time
Next, is to calculate the required distance
In this case:
because it is constant and
The expression becomes:
Make Distance the subject:
<em>The peacock will walk 39.2 feet in 98 seconds</em>
Step-by-step explanation:
The law of cosine states that:
, where C is the side opposite of angle theta, and A and B are the adjacent sides of the angle.
In this case, A is equal to 21, and B is equal to 30 (or it could also be the other way around). That means that:
