Answer:
3x m²
Step-by-step explanation:
Area is length × breadth
So
A= 3 × x
A= 3x m²
119 times .5 equals $59.5
$119-$59.5=$59.5
Answer:
Answer
its obvious is A
Step-by-step explanation:
just cal it
Given that

attains a maximum at

, it follows that

at that same point. So integrating once gives



and so the first derivative is

.
Integrating again, you get


You know that this curve passes through the point (2, -1), which means when

, you have

:


and so
