Find a power series for the function, centered at c. f(x) = 1 9 − x , c = 4 f(x) = [infinity] n = 0 Incorrect: Your answer is in
Wewaii [24]

Looks like the given function is

f(x)=\dfrac1{9-x}

Recall that for |<em>x</em>| < 1, we have

\displaystyle\frac1{1-x}=\sum_{n=0}^\infty x^n

We want the series to be centered around x=4, so first we rearrange <em>f(x)</em> :

\dfrac1{9-x}=\dfrac1{5-(x-4)}=\dfrac15\dfrac1{1-\frac{x-4}5}

Then

\dfrac1{9-x}=\displaystyle\frac15\sum_{n=0}^\infty\left(\frac{x-4}5\right)^n

which converges for |(<em>x</em> - 4)/5| < 1, or -1 < <em>x</em> < 9.

Answer:

The volume of tank to the nearest cube is 503 ft³

Step-by-step explanation:

Given that,

Diameter of tank = 8 ft

radius = 4 ft

Height = 10 ft

We need to calculate the volume of tank

Using formula of volume

V= \pi r^2h

Where, r = radius

h = height

Put the value into the formula

V=\pi\times4^2\times10

V=502.6\ ft^{3}

V=503\ ft^{3}

Hence, The volume of tank to the nearest cube is 503 ft³
