Always true.
the meaning of a multiple is the product result of one number multiplied by another number, so if we are taling aout LCM ( Least common multiple) then it will always be a product of two numbers.
Step-by-step explanation:
h = -490t² + 1470t
When h = 980:
980 = -490t² + 1470t
Simplifying:
0 = -490t² + 1470t - 980
0 = t² - 3t + 2
Factoring:
0 = (t - 1) (t - 2)
t = 1, 2
There are two solutions because the rocket first reaches the height of 980 cm as it's going up at 1 second, then it reaches that height again as it's coming down at 2 seconds.
You need to look at this as a proportion and ratio.
