PLEASE HELP!!

madam [21]

Answer:

k=2/3

Step-by-step explanation:

Step 1:

Step 1 in solving the exponential equations is re-writing the base same as other side of the equation

so,

$25^{3k}=625\\=> 25^{3k}=25^2$

Step 2:

Second step is equating the exponents

The rule used is:

$If\ B^m=B^n\ then\ m=n$

So in this case

$3k=2\\k = \frac{2}{3}$

So the solution is:

k=2/3 ..

What is the angular velocity of a 6–foot pendulum that takes 3 seconds to complete an arc of 14.13 feet? Use 3.14 for π.

irakobra [83]

The angular velocity is the linear speed divided by the radius.
ω = d/(t*r) = (14.13 ft)/((3 s)*(6 ft))
ω = 0.785 radians/second
There are 180/π degrees per radian, so the angular velocity can also be written as ...
ω = 45 degrees/second
