Use the Pythagorean Theorem to find the length of the side marked "x."
x^2 + (10 mi)^2 = (13 mi)^2.  Thus, x^2 + 100 mi^2 = 169 mi^2.
Next, x^2= (169-100) mi^2, or x^2 = 69 mi^2.  Find the positive square root of both sides of this equation.  What is it?

Answer:
2998 ; 17%
Step-by-step explanation:
Given the function:
t(c)=-3970.9(ln c)
c = % of carbon remaining ; t = time
1.) c = 47% = 47/100 = 0.47
t(0.47) = - 3970.9(In 0.47)
t = - 3970.9 * −0.755022
t = 2998.119
t = 2998
B.) 
t = 7000
t(c)=-3970.9(ln c)
7000 = - 3970.9(In c) 
7000 / - 3970.9 = In c
−1.762824 = In c
c = exp(−1.762824) 
c = 0.1715596
c = 0.1715596 * 100%
c = 17.156% ; c = 17%
