The result of a dry gas analysis of an engine exhaust is co2 = 10.7%, co=5.8%, and n2=83.5%. stating any assumptions, use the rich gas equation to find the gravimetric air/fuel ratio.

the correct answer is answer a. a mixture

no other options make sense

hope this

have a great day : )

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.
