Answer:
A
Step-by-step explanation:
When solving for x as an exponent, we need to use logarithms in order to undo the operation and rearrange the terms. We use log rules to bring down the exponent and solve. Logarithms are the inverse operations to exponents and vice versa. We have one special kind of logarithm called the natural logarithm whose base is e. We write it as ln. Since our base is e here, we will use the natural logarithm to rearrange and isolate x.
We begin by applying the natural logarithm to each side.
Log rules allow use to rearrange the exponent as multiplication in front of the log.
ln e as an inverse simplifies to 1.
We now apply the inverse operations for subtraction and multiplication.
Option A is correct.
Answer:
The volume of rectangular box is 9,000 cubic centimeters
Step-by-step explanation:
Given as :
The length of the rectangular sheet = L = 62 cm
The width of the rectangular sheet = B = 42 cm
Let The volume of rectangular box = v cubic centimeters
From each corner of sheet a square of 6 cm is cut out and an open box made
So, The length of box = L' = (L - 6 - 6)
i.e L' = (62 - 6 - 6)
Or, L' = 50 cm
Or, Length of the box = 50 cm
And The width of the box = B' = (B - 6 - 6)
i.e B' = (42 - 6 - 6)
Or, B' = 30 cm
Or width of the box = 30 cm
And,
The height of the box = H = 6 cm
∴ volume of rectangular box = Length of box × Breadth of box × Height of box
i.e v = L' × B' × H
Or, v = 50 cm × 30 cm × 6 cm
Or, v = 9,000 cm³
So, The volume of rectangular box = v = 9,000 cm³
Hence, The volume of rectangular box is 9,000 cubic centimeters Answer
