Nothing to do to simplify any further, other than factoring out .
Answer:
The 4 interior angles in the square are each 90 degrees. The four angles formed by the intersection of the 2 diagonal lines are each 90 degrees. The rest of the angles <PQT, <RQT, etc. Are all 45 degrees.
$18 is 30% or 0.3 of 60 dollars
The first step in solving this question is to split the journey into 2 parts. In the first part of the journey, miles are covered at a speed of 40 mph. In the second part the journey 5 miles are covered at a speed of 60 mph.
The equation to compute the time of a journey given the speed and distance is where is the time, is the speed and is the distance.
The time for the first part of the journey is calculated as shown below,
.
The time for the second part of the journey is calculated as follows,
.
The total time is the sum of the times taken to cover each part of the journey and is calculated as shown below,
The time to cover the journey is a third of an hour or 20 minutes.
f(x) = 4^x
f(1) just means we plug 1 in for x.
4^1 = 4
So, f(1) = 4^1 = 4
