Miss Black completes a journey in 3 stages.
In stage 1. she drives at a speed of
40km/h for 45 minutes.
In stage 2, she drives at 60 km/h for
2 hours 9 minutes.
Altogether, over the 3 stages, Miss
Black drives 171.6km in 3 hours 15
minutes
What is her average speed, in km/h,
in stage 32

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1

step-by-step explanation:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
