Answer: x = log₃₇(12)
Step - by - step explanation:
1. Remove the variable from the exponent using logarithms
37^x=12
Take the common logarithm of both sides of the equation:
log₁₀(37^x)=log₁₀12)
Use the log rule: log_a(x^y)=y*log_a(x) to move the exponent outside the logarithm:
x*log₁₀(37)=log₁₀(12)
2. Isolate the x-variable
x*log₁₀(37)=log₁₀(12)
Divide both sides of the equation log₁₀(37) by:
x = log₁₀(12) / log₁₀(37)
Use the formula ![log_{b}(x)/log_{b}(a) = log_{a} (x)](https://tex.z-dn.net/?f=log_%7Bb%7D%28x%29%2Flog_%7Bb%7D%28a%29%20%3D%20log_%7Ba%7D%20%28x%29)
to combine the logarithms into one:
x=log₃₇(12)
Decimal form:
x=0.6881648129099501

Answer: 17.69 miles
Step-by-step explanation:
Activity time (hours) :
Activity - - - - - - - - - - - - - time (hours)
Hiking - - - - - - - - - - - - - - - - - - - - 3
Mountain biking - - - - - - - - - - - 1.45
Horseback riding - - - - - - - - - - 1.2
Cross-country skiing - - - - - - - - 0.75
Average speed = 12.2 miles per hour.
How many miles did Brian bike?
Recall;
Speed = distance ÷ time
Distance = speed × time
Speed = 12.2 mi/hr
biking time = 1.45 hours
Distance (mountain biking) = 12.2 × 1.45 = 17.69 miles
