F(x) = 2ln(x) + c [integral of 1/x is ln x]
f(e^(1/2)) = 2ln(e^(1/2)) + c = 5
2(1/2) + c = 5 [ln(e^a) = a]
1 + c = 5
c = 4
So:
f(e) = 2ln(e) + 4 = 2 + 4 = 6

Answer:
Step-by-step explanation:
See attachment for complete question
Let the position of the submarine be represented with X
Given
First, we calculate angle at X.
Solving (a): Distance AX: The distance between ship A and the submarine
To do this, we apply sine formula which states
In this case:
Substitute values for AB, and
Make AX the subject
Solving (b): Distance BX: The distance between ship B and the submarine
To do this, we apply sine formula which states
In this case:
Substitute values for AB, and
Make BX the subject
Answer:
120°
Step-by-step explanation:
Recall:
The sum of interior angles if a parallelogram equals 360;
The sum of the angles can be defined as :
(x + 2x + x + 2x) = 360
6x = 360
x = 360/6
x = 60°
The angle BCD = 2x
Hence, angle BCD = 2(60°) = 120°
the correct answer would be c i took the test and i know its correct
have a nice day
