f(x) = 93 log(d) + 65
When f(x) = 400 :
400 = 93 log(d) + 65
93 log(d) = 335
log(d) = 335/93
d = 10^(335/93)
d = 4000.834 ≈ 4000
Estimated distance it can travel = 4000 miles
When f(x) = 400 :
400 = 93 log(d) + 65

d = 4000.834 ≈ 4000

f(d)=93log(10)d+65
f(d)=400
=>
400=93log(10)d+65
=>
log(10)d=3.602150538
=>
d=10^3.602150538
=>
d=4000.834053 miles
f(d)=400
=>
400=93log(10)d+65
=>
log(10)d=3.602150538
=>
d=10^3.602150538
=>
d=4000.834053 miles

log d = 335/93
d = 4000.83 miles
d ≈ 4000 miles
d = 4000.83 miles
d ≈ 4000 miles

f(x) = 93 log d + 65
400 = 93 log d + 65
93 log d = 400 - 65
93 log d = 335
log d = 335 / 93
d = 10^(335/93)
d = 4000...................ANS
400 = 93 log d + 65
93 log d = 400 - 65
93 log d = 335
log d = 335 / 93
d = 10^(335/93)
d = 4000...................ANS

The function f(x) = 93 log d + 65 relates the speed of the wind, f(x),
in miles per hour near the center of a tornado to
the distance that a tornado travels in d miles.
If the tornado has sustained winds of 400 mph,
estimate the distance it can travel.
f(x) = 93 log d + 65
400 = 93 log d + 65
93 log d = 335
Solution:
d ≈ 4000.8 miles
in miles per hour near the center of a tornado to
the distance that a tornado travels in d miles.
If the tornado has sustained winds of 400 mph,
estimate the distance it can travel.
f(x) = 93 log d + 65
400 = 93 log d + 65
93 log d = 335
Solution:
d ≈ 4000.8 miles
