How do I solve this?
50e^(0.035x)=200

x ≈ 39.608

Step-by-step explanation:

Using the rule of logarithms

log = nlogx and lne = 1

Given

50 = 200 ( divide both sides by 50 )

= 4 ( take the ln of both sides )

ln = ln4 , that is

0.035xlne = ln4

0.035x = ln4 ( divide both sides by 0.035 )

x = ≈ 39.608 ( to 3 dec. places )

it's

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
