If three equal subdivisions of [-4, 2] are used, find the trapezoidal approximation of integral of (e^(-x))/2 dx from -4 to 2.

nikklg [1K]

Trapezoidal rule:
$\int\limits^b_a {f(x)} \, dx=(b-a)* \frac{f(a)+f(b)}{2}$
... = $(2+4)* \frac{e ^{4} +e ^{-2} }{4}$
= $6* \frac{e ^{4} + \frac{1}{e ^{2} } }{4}$
= $\frac{3(e ^{6}+1) }{2e^{2} }$

A sphere is dilated by a scale factor of 1.5 to create a new sphere. How does the volume of the new sphere compare with the volu

SashulF [63]

Answer:

The volume of new sphere is 3.375 times greater than the volume of old sphere

Step-by-step explanation:

Let r be the radius of old sphere. This old sphere is dilated by a scale factor of 1.5 to create a new sphere, so the radius of new sphere is R=1.5r.

The volume of the sphere can be calculated using formula

$V=\dfrac{4}{3}\pi r^3$

Hence,

$V_{old}=\dfrac{4}{3}\pi r^3\\ \\V_{new}=\dfrac{4}{3}\pi R^3=\dfrac{4}{3}\pi (1.5r)^3\\ \\\dfrac{V_{new}}{V_{old}}=\dfrac{\dfrac{4}{3}\pi (1.5r)^3}{\dfrac{4}{3}\pi r^3}=1.5^3=3.375$
