Answer:
- net A is correct
- surface area is 98.4 square inches
Step-by-step explanation:
<u>Part A</u>:
The two right-angle corners of the triangular bases are at either end of the same edge. This is only shown correctly in Net A.
__
<u>Part B</u>:
See the attached annotated diagram. Dimensions are in inches.
__
<u>Part C</u>:
The total surface area is the sum of the three central rectangles of the net and the two triangles. As shown in the attached, the two triangles can be considered as one rectangle of dimensions 3 in by 4 in.
The total area is ...
Surface area = base area + face area
= (3 in)(4 in) + (3 + 4 + 5 in)(7.2 in) = 12 in² +86.4 in²
Surface area = 98.4 in²
Answer:
Step-by-step explanation:
lets calculate the derivate of f using the chain rule:
we have that f'(1) = 4e^2, hence the equation is
or, equivalently,
