Use a linear approximation to estimate the number (8.07)^2/3.
Tanya [424]
So let f(x) = x^(2/3) 
<span>Then let f'(x) = 2/3 x^(-1/3) = 2 / (3x^(1/3)) </span>

<span>When x = 8, </span>
<span>f(8) = 8^(2/3) = 4 </span>
<span>f'(8) = 2 / (3*8^(1/3)) = 1/3 </span>

<span>So near x = 8, the linear approximation is </span>
<span>f(x) ≈ f(8) + f'(8) (x - 8) </span>
<span>f(x) ≈ 4 + 1/3 (x - 8) </span>

<span>So the linear approximation for x = 8.03 is... </span>
<span>f(8.03) ≈ 4 + 1/3 (8.03 - 8) </span>
<span>f(8.03) ≈ 4 + 1/3 (0.03) </span>
<span>f(8.03) ≈ 4.01 </span>

<span>8.03^(2/3) ≈ 4.01 </span>

Jill and Marcy go to an ice cream store where they have the option of getting a smoothie in either a cylindrical or rectangular
k0ka [10]

Answer: Jill got the larger smoothie and its volume is 1609.14 cubic cm.

Step-by-step explanation:

Since we have given that

Jill purchased the cylindrical container.

Height of container = 8 cm

Radius = 8 cm

So, volume of cylindrical container would be

\pi r^2h\\\\=\dfrac{22}{7}\times 8\times 8\times 8\\\\=1609.14\ cm^3

Marcy purchased the rectangular container.

Height of container = 8 cm

Width = 8 cm

Length = 8 cm

so, volume of rectangular container would be

l\times b\times h\\\\=8\times 8\times 8\\\\=512\ cm^3

Hence, Jill got the larger smoothie and its volume is 1609.14 cubic cm.
