Use a graphing utility to graph the function and the damping factor of the function in the same viewing window.

Bas_tet [7]

Answer:

The function touches the damping factor

at x= $\frac{(4n-3)\pi}{2}$ and x= $\frac{(4n-1)\pi}{2}$

The x-intercept of f(x) is

at x= $n\pi$

Step-by-step explanation:

Given function is f(x)= $e^{-3x} sin(x)$ and damping factor as y= $e^{-3x}$ and y= $(-1)e^{-3x}$

To find when function touches the damping factor:

For f(x)= $e^{-3x} sin(x)$ and y= $e^{-3x}$

Equating the both the equation,

$e^{-3x} sin(x)=e^{-3x}$

$sin(x)=1$

x= $\frac{(4n-3)\pi}{2}$

For f(x)= $e^{-3x} sin(x)$ and y= $(-1)e^{-3x}$

Equating the both the equation,

$e^{-3x} sin(x)=(-1)e^{-3x}$

$sin(x)=(-1)$

x= $\frac{(4n-1)\pi}{2}$

Therefore, The function touches the damping factor x= $\frac{(4n-3)\pi}{2}$ and x= $\frac{(4n-1)\pi}{2}$

To find x-intercept of f(x):

For x-intercept, y=0

f(x)= $e^{-3x} sin(x)$

y= $e^{-3x} sin(x)$

$e^{-3x} sin(x)=0$

Hence, $e^{-3x}$ is always greater than zero.

Therefore, $sin(x)=0$

x= $n\pi$

Thus,

The x-intercept of f(x) is at x= $n\pi$

Which expression is equivalent to 10x2y + 25x2?

babymother [125]

$10 x^{2} y +25 x^{2} = 5 x^{2} ( \frac{10 x^{2} y +25 x^{2} }{5 x^{2} }) = 5 x^{2} ( \frac{10 x^{2} y}{5 x^{2} } + \frac{25 x^{2} }{5 x^{2} } ) = 5 x^{2} ( \frac{2y}{1} + \frac{5}{1} )$

Answer A 5x² * ( 2y + 5)

A customer deposits $500 in an account that pays 4% annual interest. What is the balance after 3 years if the interest is compou

SIZIF [17.4K]

Answer:

Option D

Step-by-step explanation:

The compounded interes formula states that:

V(t) = P (1 + r/n)^ (nt)

t = years since initial deposit = 3

n = number of times compounded per year 1

r = annual interest rate (as a decimal) = 4% / 100 = 0.04

P = initial (principal) investment = $500

Then V(t) = $500 ( 1 + 0.04/1)^3 = 562,43

So the correct answer is option D.
