A school principal is mapping out some new features for a triangular playground. He sketches the playground on grid paper. The coordinates of the vertices of the playground are (1, 10), (−5, 2), and (7, 2). The principal wants to put monkey bars at the orthocenter of the playground. What are the coordinates of the monkey bars? (__,__)

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

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.
