Pls help if you can, Thx! Phoenix, Arizona, is a city in the Southwestern desert. Summers are extremely hot. Winter days are often fairly warm but winter nights can be quite chilly. In December, inversions are quite common. How does an inversion form under these conditions and what are the consequences of an inversion to this sprawling, car-dependent city?

It is hoped that these data will help residents, visitors, prospective residents, ... The climate is of a desert type with low annual rainfall and low relative humidity. ... drop below freezing during the three coldest months, but the afternoons are usually ... The change from the heat of summer to the mild winter temperatures (sorry if its wrong :(

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.

there is none because earth is stationary and flat.
