In the given figure for <R ,the opposite side is r and the adjacent side is s.

Given r=7,s=10.

Tan of any angle is the ratio of opposite and hypotenuse.

Tan R=\frac{opposite }{hypotenuse}

Substituting values of opposite r=7 and adjacent s=10 we have:

Tan R =\frac{7}{10} =0.7R= Tan^{-1} (0.7)

R= 34.99 degrees

R= 35 degrees

Option A is the right answer.

If the half-life of a radioactive substance is 2,800 years, then at what rate is it decaying?
vlada-n [284]

Answer:

0.0001075

Step-by-step explanation:

The relation between halflife and rate at which it is decaying is given by

t_{\frac{1}{2} } =\dfrac{log2}{rate}

now in the above problem halflife is given as 2800 years substituting in the above equation we get the value of rate at which it is decaying to be rate=0.0001075.
