Item                          Time bought
MIcroscopes             Every 5 years
Safety goggles          Every 4 years
Test Tube                  Every 2 years

It would take 20 years for them to buy these three items at the same time.

We simply need to find the LCM or least common multiple of the 3 items using the number of years.

Microscopes - 5 years → 5, 10, 15, 20
Goggles - 4 years → 4, 8, 12, 16, 20
Test tubes - 2 years → 2, 4, 6, 8, 10, 12, 14, 16, 18, 20

What is the answer 4(t)=50t/t^2+25
sveta [45]

Answer:

Step-by-step explanation:

50t/(t^2+25)

4(t) = [50(t^2+25)-50t(2t)]/(t^2+25)^2 = (-50t^2+1250)/(t^2+25)^2

=  -50(t^2-25)/(t^2+25)^2    

Roots of 4(t) are 5 and -5
