There are 3 lighthouses along a strip of the coast. Lighthouse A shines its light on for 3 seconds and then off for 3 seconds. Lighthouse B shines its light on for 4 seconds and then off for 4 seconds. Lighthouse C shines its light on for 5 seconds and then off for 5 seconds. If all 3 lighthouses start shining their lights on at the same time when will be the next time all three lighthouses will shine their lights on at the same time?

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
