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%

Answer:
The Answer is: y - 8 = 5/3(x - 3)
Step-by-step explanation:
Given the y intercept form:
y = 5/3x + 3
Note that the slope is 5/3.
Find a point on the line.
Choose x = 3, solve for y:
y = 5/3(3) + 3
y = 5 + 3
y = 8
This give you the point:
(3, 8)
Use this to substitute into the point slope equation:
y - y1 = m(x - x1)
y - 8 = 5/3(x - 3)
The domain are the X values.
Each set of parenthesis is written as (x,y), so the domain would be the first number in each set of parenthesis.
{-3, -1, 0, 1, 5}
