Answer:
The correct answer is C.
Step-by-step explanation:
In order to solve this problem, you need to simplify the equation by using a natural log (ln). This will cancel out the e and make it easy to solve.
e^(2x + 5) = 4 ----> Take the ln
lne^(2x + 5) = ln(4) ------> Simplify
2x + 5 = ln(4) ------> Subtract 5
2x = ln(4) - 5 -----> Divide by 2
x = [ln(4) - 5]/2
Answer:
Answer: The bottom or last answer.
Step-by-step explanation:
e^(2x + 5) = 4 Take the ln of both sides.
ln(e^(2x + 5)) = ln(4) Modify the left side. When e^z is logged you get z
2x + 5 = ln(4) Subtract 5
2x + 5-5 = ln(4) - 5 Simplify
2x = ln(4) - 5 Divide by 2
x = [ ln(4) - 5]/2 Answer

Answer:
9 inches.
Step-by-step explanation:
The formula for the volume of a rectangular prism is base x height. So if the volume is 378, and the base is 42, you would use the equation 378/42 to find the height. 378/42 is 9. Therefore, the height is 9 inches.
