Asubmarine descends from sea level to the entrance of an underwater cave. the elevation of the entrance is -120 feet. the rate of change in the submarine's elevation is less than -12 feet per second. can the submarine reach the entrance to the cave in less than 10 seconds? explain.

b 1: 45 am

step-by-step explanation:

its that because if it was in the pm it would be 1345

the first one, all those points on the line just make a strait line.

answer: -0.5 would be the most likley outcome

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
