Answer:
ln (m^2n^9)
Step-by-step explanation:
Rule: ln a + ln b = ln ab
Rule: ln a^n = n * ln a
2 ln m + 9 ln n =
= ln m^2 + ln n^9
= ln (m^2n^9)
=

Answer:
6.3
Step-by-step explanation:
First off, we need the distance formula, which is:

If we plug in the points, we get:

If we simplify everything under the square root, we get:



In decimal, the answer is 6.3
Use distributive method
5r - 50 = -51
Add 50
5r = -1
Divide by 5
r = -1/5
