Asubmarine is 730 m below sea level. an airplane that is directly over the submarine is 9,144 m above sea level. what is the vertical distance between the submarine and the airplane?

9,874 meters.

Step-by-step explanation:

We have been given that a submarine is 730 m below sea level. This means that altitude of the submarine would be .

We are also told that an airplane that is directly over the submarine is 9,144 m above sea level. The altitude of the airplane would be .

To find the vertical distance between the submarine and the airplane, we will subtract elevation of submarine from elevation of airplane as:

Therefore, the vertical distance between the submarine and the airplane would be 9,874 meters.

step-by-step explanation:

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.
