What unit of measurement would you use to measure the distance from your home to the grocery store? Should be meters right?

Centimeter

Meter

Millimeter

Kilometer

the answer is kilometer.

Step-by-step explanation:

You would use kilometers.

Explanation:

It is useful when measuring long distances.

Meters are better for measuring rooms, and centimeter and millimeter are way too small to measure that sort of distance.

horizontal translation of 2 units in the positive x direction

followed by

vertical translation of 3 units in the positive y direction

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.
