in a village the bell rings every 30 minutes at the junior school and every 45 minutes at the high school both schools start lessons at 8 a. m. if the high school bell ring 45 minutes how many times during the day with this bell ring at the same time as the Junior ​

12:00

Concept

Sum

LCM = 2 * 2 * 2 * 3 * 5 = 120 minutes.

Therefore

we can conclude that, both bells will ring again together after 120 minutes or 2 hours. 10AM + 2 hours = 12:00 noon.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
