<span>A line is a geometrical system that consists of two points. Horizontal lines are those that are parallel to the x-axis of the plane and have a slope of zero. Vertical lines are those that are parallel to the y-axis of a plane and have an infinite slope. Perpendicular lines are those that form a 90 degree angle with a second line. </span>
Answer:
Distance = 10 km
Step-by-step explanation:
Let x be the number of hours taken from school to town and y be the number of hours taken back to the school
Then distance covered during first trip would be 10x (distance = speed*time) and during the second trip would be 8y. Both distances are equal.
=> 10x = 8y
Dividing both sides by 2
=> 5x = 4y
=> 5x-4y = 0 ------------------(1)
<u><em>The total time for both the trips is:</em></u>
=> x + y = 2.25 -------------------(2)
Multiplying eq (2) by 5
=> 5x+5y = 11.25 ---------------(3)
Subtacting (3) from (1)
=> 5x-4y-5x-5y = 0-11.25
=> -4y-5y = -11.25
=> -9y = -11.25
Dividing both sides by -9
=> y = 1.25 hrs
Putting in (2)
=> x + 1.25 = 2.25
=> x = 2.25 - 1.25
=> x = 1 hr
<u><em>Now, Calculating the Distance</em></u>
=> Distance = 10x
=> 10 ( 1 )
=> Distance = 10 km
The correct answer is option number 3: 27
Step-by-step explanation:
The term from explicit formula is calculated by putting the value of n in the explicit formula
Given
As we have to find the 5th terms, we will put n=5
5th term is 27
Hence,
The correct answer is option number 3: 27
