Ln 30 + ln 2 - ln 12
ln (30 * 2) - ln 12 (when there is a + between ln you can multiply the numbers)
ln 60 - ln 12
ln (60/12) (the - sign says to divide the numbers)
ln 5 - final answer
Answer:
B.
Step-by-step explanation:
The original equation is cos 64 = 32/k. To solve for k we need to isolate it. we can multiply by k then divide by cos 64. This gives us the equation k = 32/cos 64. Therefore, B is the right answer.
D
Adding a negative is the same as subtracting
Correct answers are A and B.
The more precise answers are the numbers which could be rounded to 180. Those are 180.4 and 175.
