Answer:
8x10^-6
Because the decimal point must be moved left 6 places in order to be equal when multiplied by the whole number the 10 must be to the -6th
Given that the diameter of a human hair
Given that the diameter of a spider's silk
Now we have to find how much greater is the diameter of a human hair than the diameter of a spider's silk.
To find that we just need to subtract the given numbers.
Since powers are not same so let's make them equal
now we can easily subtract the coefficients that is 3 from 9
Hence final answer is .
Yes. You did it right. Most of the angles are corresponding, and once you found the measure of x, you could use the corresponding angles postulate.
-4sqrt(x)-3 = 12 -> sqrt(x) - 3 = -3 -> sqrt(x) = 0
so x = 0, only solution, no extraneous solution
