How do you use the product rule to find the derivative of y=x√⋅cos(x)y=sqrt(x)*cos(x) ?

1 answer:

7 0

$y=\sqrt x\cos x\\
y'=(\sqrt x)'\cos x+\sqrt x (\cos x)'\\
y'=\frac{1}{2\sqrt x}\cos x+\sqrt x\cdot(-\sin x)\\
y'=\frac{1}{2\sqrt x}\cos x-\sqrt x\sin x\\
$

What are the Values of h and k?

lawyer [7]

Answer:

$h=4, k=-2$

Step-by-step explanation:

we know that

In the function f(x) the inflection point is at $(0,0)$

In the function g(x) the inflection point is at $(4,-2)$

the rule of the translation of f(x) to g(x) is equal to

$(x,y)-----> (x+4,y-2)$

That means-----> the translation is $4$ units to the right and $2$ units down

The equation of g(x) is equal to

$g(x)=(x-4)^{3} -2$

therefore

$h=4, k=-2$

An average adult can hear sounds with frequencies between 20 waves per second and 16,000 waves per second. What is the wavelengt

frez [133]

Answer:

The wavelength, of a sound wave with a frequency of 20 waves per second is 15,000,000 m.

Step-by-step explanation:

In this question, we have to calculate the wavelength of a sound wave of frequency 20 waves per second.

We know that the speed of light in air/ vacuum is $3\times 10^{8}$ .

Now by the formula v = nλ , where v = speed of light in air/vacuum, n = frequency of the wave and λ = wavelength in meters,

we put the values

$3\times 10^{8}$ = 20 × λ

λ = $\frac{3\times 10^{8}}{20}$

λ = 15,000,000 m
