#9 is correct.
#10 is actually choice 2.
This is because the difference of logs with the same base (log(x)-log(y)) is equal to the log of the two numbers divided by each other, so log(x)-log(y) would equal log(x/y). In your case, log(15)-log(10) => log(15/10) => log(3/2), final answer.
It is equal to 9.461 x 10 km
Answer:
a right triangle
Step-by-step explanation:
because if you rotate your head, then you can see that the top is at a 90 degree angle
Answer:
Step-by-step explanation:

First let's multiply both sides by 2 to remove the
fraction:

Next, let's divide both sides by
:

Finally, let's subtract
from both sides:

Answer:
x=58 degrees
Step-by-step explanation:
The angle is a right angle (90 degrees)
90-32=58
