Maths ( a ship was travelling on a bearing of 270°. Another way of discribing its direction is? ) A)north
B)south
C) east
D) west

Step-by-step explanation:

It starts at 0 degrees which is the x axis going east. 270 degrees, by convention goes counter clockwise. So that takes you to the minus y axis. You are not going south.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
