Two submersibles, one red and one blue, started rising toward the surface at the same time. they each rose at a constant speed. the red submersible starts rising from an altitude of 80 meters below the surface. after 30 seconds, it was 60 meters below the surface. the following equation gives the altitude (in meters relative to the surface) of the blue submersible as a function of time (in seconds). a= -90 + 0.6t

which submersible started rising from a higher altitude?

which submersible rose faster?

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to

m∠a is 90°
