1) The minimum thickness of Saturns A ring is one-tenth kilometer. Write this decimal using a negative exponent.

yulyashka [42]

Answer:

1) $10^{-1}$

2) $2^{-2}$

3) $12^{-2}$

Step-by-step explanation:

Using negative exponent rule:

1) one -tenth of kilometer =.1 = $\frac{1}{10}=10^{-1}$

Using negative exponent rule:

2) $\frac{1}{4} =\frac{1}{2^{2} }=2^{-2}$

Using negative exponent rule:

3) $\frac{1}{144} =\frac{1}{12^{2} }= 12^{-2}$

The angle of elevation of the top of a tree from a point 100 meters from the foot of the tree is 36 degrees. How high is the tre

Veseljchak [2.6K]

To answer this question we can think Soh Cah Toa. If we are 100 ft from the tree and at an angle of 36 degrees and we want what I call the rise we can us the Toa formula tan(36)=o/100 then manipulate algebraically until we get the following o=tan(36)(100) this give us the height (o) to be 72.65 meters
