Answer:
False
Step-by-step explanation:
This is false. We can disprove this by plugging in the number into the function f(x) = lnx
f(0) = ln0
Since
,
This is not 0 so f(0) cannot be equal to 0, thus disproving the statement.
Answer: x = 34º, y = 146º, z = 146º
Step-by-step explanation:
Adding the angles inside a triangle gives you 180º. So
85 + 61 + x = 180
146 + x = 180
x = 34º
x and y are supplementary, so y = 180 - x = 180 - 34 = 146º.
y and z are equal (vertical angles), so z = 146º.
Answer:

Step-by-step explanation:
A: The root will be rational if the product of the numbers under the radicals is a perfect square. For this part, there are a couple of choices.
