Tides (the rise and fall in sea level) are caused by the gravitat moon together with the earth's rotation. In most places at the coast, there are two high tides (high water) and two low tides (low water) every day. Below is a tidal table showing the times for high tide and for low tide for three days in March 201 at the Durban coast: Low Low Day 10:19 am High 04:12 am 04:39 am High 04:23 pm 04:50 pm 05:18 pm 10:29 pm 10:56 pm 11:25 pm Mo 17 10:46 am Tu 18 A 5:07 am We 19 Source: http://www. tide-forecast. com/locations/Durban-South-Africa/t ides/latest 1.1 At what time in the morning will it be low tide on Tuesday 18 March? 1.2 Write 05:18 pm in 24-hour format.​

answer: a

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.

you,

mrb

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

b.
