Differentiate Functions of Other Bases In Exercise, find the derivative of the function.

Maslowich

Answer:

$\frac{dy}{dx}=3x^{3x}(lnx+1)$

Step-by-step explanation:

We are given that a function

$y=x^{3x}+1$

We have to find the derivative of the function

Let $u=x^{3x}$

$y=u+1$

Taking ln on both sides

$lnu=3xln x$

By using $lna^b=blna$

Differentiate w.r.t x

$\frac{1}{u}\frac{du}{dx}=3(lnx+x\times \frac{1}{x})=3(lnx+1)$

$\frac{d(lnx)}{dx}=\frac{1}{x}$

$\frac{d(u\cdot v)}{dx}=u'v+v'u$

$\frac{du}{dx}=3u(lnx+1)=3x^{3x}(lnx+1)$

Differentiate y w.r.t x

$\frac{dy}{dx}=\frac{du}{dx}$

Using the value of du/dx

$\frac{dy}{dx}=3x^{3x}(lnx+1)$

What is the length of Line segment B C, rounded to the nearest tenth? 13. 0 units 28. 8 units 31. 2 units 33. 8 units.

Len [333]

The length of the line segment BC is 31.2 units.

<h2>Given that</h2>

Triangle ABC is shown.

Angle ABC is a right angle.

An altitude is drawn from point B to point D on side AC to form a right angle.

The length of AD is 5 and the length of BD is 12.

<h3>We have to determine</h3>

What is the length of Line segment BC?

<h3>According to the question</h3>

The altitude of the triangle is given by;

$\rm Altitude = \sqrt{xy}$

Where x is DC and y is 5 units.

Then,

The length DC is.

$\rm Altitude = \sqrt{xy}\\
\\
12 = \sqrt{(DC) \times 5}\\
\\
\sqrt{DC } = \dfrac{12}{\sqrt{5}}\\
\\
$

Squaring on both sides

$\rm DC = \dfrac{144}{5}\\
\\
DC = 28.8$

Considering right triangle BDC, use the Pythagorean theorem to find BC:

$\rm BC^2 = DC^2+BD^2\\\\ BC^2 = (28.8)^2+(12)^2\\

\\
BC = \sqrt{829.44+144}\\
\\
BC = \sqrt{973.44}\\
\\
\rm BC = 31.2 \ units$

Hence, the length of the line segment BC is 31.2 units.

Find the equation of the line that passes through the point left-parenthesis 1 comma 8 right-parenthesis and is perpendicular to

Furkat [3]

Don't be shy about using actual parentheses and commas.

Line through (1,8) perpendicular to

$-\dfrac 4 5 x + \dfrac 5 4 y = -4$

The perpendicular family is gotten by swapping the coefficients on x and y, negating exactly one of them. The constant is given directly by the point we're through:

$\dfrac 5 4 x + \dfrac 4 5 y = \dfrac 5 4 (1) + \dfrac 4 5 (8) = \dfrac 5 4 + \dfrac{32}{5}$

Let's clear the fractions by multiplying both sides by 20.

$25x + 16y = 25 + 128 = 153$

Might as well stop here.

Answer: 25 x + 16 y = 153
