The possible values of tan^-1(1) are (3π + 4n)/4
<h3>How to determine the possible values?</h3>
The expression is given as:
tan^-1(1)
To determine the possible values, we plot the graphs of
y = tan(x) and y = 1
From the graph, we have the following values
tan^-1(1) = (3π + 4n)/4 when n = ±{0,1,2....}
Hence, the possible values of tan^-1(1) are (3π + 4n)/4

Answer: 6.24 tablespoons
Explanation: okay so if $.39 is 2 tablespoons, then you can multiply that by 8 because there are 8 tablespoons in half a cup. After you multiply that just multiply it by 2 because they are trying to make two pies. And that’s how you your answer.
After 2 years value of the phone is $128. option C
Step-by-step explanation:
Given,
Original price of the phone = $ 800
Each year it loses 
of its value.
To find the value of phone after 2 years.
In 1st years
The value of the phone is= $800 - (800×)
= $ 800-240 = $ 320
In 2nd year
The value of the phone is= $320 - (320×)
= $ 320 - 192 = $ 128
Hence,
After 2 years value of the phone is $128.
Answer:
Step-by-step explanation:
You can figure out the angle DBC by the alternate interior theorem. Angle DBC=56 degrees. You already figured out BD.
Since we know BD, BC, and the angle DBC we can use the Law of cosine to find CD
The law of cosine is
CD^2=BC^2+BD^2-2(BC)(BD)cos DBC
Plug in what we know
CD^2=18^2+12.1^2-2(18)(12.1)cos 56
CD^2≈228.8387
Find the square root to isolate CD.
CD≈15.1
