Answer:

8.7 \times 10^{-5}

Step-by-step explanation:

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 = (90-3) \times 10^{-6}

= 87 \times 10^{-6}

= 8.7 \times 10^{-5}

MATH PROBLEM!! PLEASE HELP!! <br>Explain your answer please

love history [14]

<h3>Answer: angle B = 47 degrees</h3>

========================================

Work Shown:

Use law of cosines to find angle B

b^2 = a^2 + c^2 - 2*a*c*cos(B)

9^2 = 6^2 + 12^2 - 2*6*12*cos(B)

81 = 36 + 144 - 144*cos(B)

81 = 180 - 144*cos(B)

81 - 180 = -144*cos(B)

-99 = -144*cos(B)

-144*cos(B) = -99

cos(B) = (-99)/(-144)

cos(B) = 0.6875

B = arccos(0.6875)

B = 46.5674634422102

B = 47 when rounding to the nearest whole number

Make sure your calculator is in degree mode.

arccos is the same as inverse cosine often labeled $\cos^{-1}$ on calculators.
