Aline has a slope of 4. what is a line has a slope of 4. what is the slope of any line perpindicular to this line? the slope of any line perpindicular to this line?

Step-by-step explanation:

We know that the product of the slopes of two lines which are perpendicular to each other is -1.

Given : The slope of a line =

Let be the slope of the other line which is perpendicular to line having slope 4.

Then, we have

Hence, the slope of any line perpendicular to line with slope 4 is  

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.
