A water sample is found to contain 59 ppm
zinc. If you drank 972 mL of this water, how
many g of zinc would you ingest?
Answer in units of g.

Explanation:

k so basically u gotta do 59/1000000 then multiply that by 972 which gives u 0.057348

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
