Practice is key in mathematics! Always search up the topic and re-read the lessons with some practice problems to see if you got it. Asking your teacher and peers to help is another way to go.
Remember, your teacher had to learn this in order to teach you about it!
Answer:
Total number of seats on plane is 150 seats.
Step-by-step explanation:
Number of seats on left side = 2 in each row
Number of seats on right side = 3 in each row
Total number of seats on right side = 90
Number of rows = total number of seats on right side/ number of seats on right in each row
Number of rows = 90 / 3 = 30 rows
So, total number of seats on left side = 30 * 2 = 60 seats
Total number of seats = total seats on right side + total seats on left side
Total number of seat = 90+ 60 = 150 seats
Hence total number of seats on plane is 150 seats.
Plug it into a graphing calculator and see where the function crosses the x-axis. Since it’s a quadratic it will cross it two times but one of the answers is negative—obviously it wouldn’t take negative second to hit the ground. It should take 9 seconds for the object to hit the ground.
