The temps that we know are colder than -5deg C 

first anything below or less than -5degC will be colder in temperature because it has a lower or smaller value, so it is colder overall. 

3 examples would be x<-5deg C

x= -6deg C
x= -7deg C
x= -8deg C

so plugging in x value we get -6<-5   -7<-5    -8<-5

If you are needing anything else please just ask! Thank you!

A golf ball í hit off the ground at an angel pi/6 travels 400ft.how long in the air
steposvetlana [31]
You can write the equations of motion as
   h(t) = -16t² + v₀sin(θ)t
   d(t) = v₀cos(θ)t

Solving the second of these for t and substituting into the first equation gives the time of flight as
   0 = -16t² + d(t)·tan(θ)
   t = √(d(t)·tan(θ)/16)

So, for d(t) = 400 and θ = π/6, this becomes
   t = √((400/16)/√3)
   t = 5/√(√3) ≈ 3.79918

The ball is in the air about 3.80 seconds.
