Double vision can be the result of .

Eye muscles relaxed from fatigue, drugs, or alcohol

Explanation:

Hello,

In this case, double vision is technically defined as diplopia, it means seeing two separated or overlapped pictures or motions of the same body when it is supposed to be looking at just one.  Thus, factors like fatigue, drugs or alcohol are diplopia promoters as they have the capacity to relax the eye muscles towards double vision.

Best regards.

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.

elements make up everything, and they combine to make compounds.

the answer is c
