Use the definition of a Taylor series to find the first four nonzero terms of the series for f(x) centered at the given value of
kolbaska11 [484]

If <em>f(x)</em> = 7/(1<em> </em>+ <em>x</em>), then

<em>f</em> (2) = 7/3

<em>f '(x)</em> = -7/(<em>x</em> + 1)²   ==>   <em>f '</em> (2) = -7/9

<em>f ''(x)</em> = 14/(<em>x</em> + 1)³   ==>   <em>f ''</em> (2) = 14/27

<em>f '''(x)</em> = -42/(<em>x</em> + 1)⁴   ==>   <em>f '''</em> (2) = -14/27

Then the Taylor series of <em>f(x)</em> about <em>a</em> = 2 is

7/3 + 1/1! (-7/9) (<em>x</em> - 2) + 1/2! (14/27) (<em>x</em> - 2)² + 1/3! (-14/27) (<em>x</em> - 2)³

= 7/3 - 7/9 (<em>x</em> - 2) + 7/27 (<em>x</em> - 2)² - 7/81 (<em>x</em> - 2)³

Akira receives a prize at a science fair for having the most informative project. Her trophy is in the shape of a
Blizzard [7]

This question is Incomplete because it lacks the appropriate diagram for the square pyramid. Please kindly find attached the required diagram

Answer:

45 square inches

Step-by-step explanation:

From the question, we are told that the foil covers the body of the trophy including the bottom, hence the formula we would be applying =

Total Surface Area of the Square pyramid = 2bs + b²

Where s = Height of the square pyramid

b = Edge length of the square pyramid

From the attached diagram, we can see that:

s = 6 inches

b = 3 inches

Total Surface Area of the Square pyramid = 2bs + b²

= 2 × 3 × 6 + 3²

= 36 + 9

= 45 square inches.

Therefore, the amount of gold foil it took to cover the trophy, including the bottom is 45 square inches
