4 0

$7^{4x-3}=22$
$\log_77^{4x-3}=\log_722$
$(4x-3)\log_77=\log_722$
$4x-3=\log_722$
$4x=3+\log_722$
$x=\dfrac{3+\log_722}4$

An elevator moves at the constant speed of 2 m/s for most of its journey. Estimate the time to travel up a 12-story building in

True [87]

Answer:

21 seconds

Step-by-step explanation:

Let us assume each story is 3.5 meters. If the building is 12 stories tall, then the elevator needs to travel 3.5*12=42 meters. Using the formula Distance = Speed * time, we get 42 = 2 *t, so t = 21 seconds.
