Wetlands are low laying lands that are constantly wet. What most occur for wetlands to be drained. A. Wetlands cannot be drained.
B. Water must be removed from from the surface of the lands until it is dry.
C. Surface water in the wetlands must be routed below ground.
D. Groundwater must be removed in sufficient quantities to drop the water table.

I think it's choice C because if we route it below the ground the surface will remain dry wild underground will be wet which will be good for soil and its fertility I think that's the answer

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.
