Which equation describes a line perpendicular to line that passes through the point 3,-4

Because we do not know the slope of this line, we can write this in point-slope form while leaving the slope as m. If given the slope at a later time you could add that.

Step-by-step explanation:

To do this, start with the base form of point-slope form and then we plug in the points.

y - y1 = m(x - x1)

y - -4 = m(x - 3)

y + 4 = m(x - 3)

the answer is 175.4379

step-by-step explanation:

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
