Derivative of (2x+5)^4(5x+2)^-2

Sveta_85 [38]

Use chain rule

$\frac{d}{dx}f(x)g(x)=f'(x)g(x)+g'(x)f(x)$

and also power rule
$\frac{d}{dx} x^m=mx^{m-1}$

so

well, we will say $f(x)=(2x+5)^4$ and $g(x)=(5x+2)^{-2}$
$f'(x)=4(2x+5)^3(\frac{d}{dy}(2x+5))=4(2x+5)^3(2)=8(2x+5)^3$
$g'(x)=-2(5x+2)^{-3}(\frac{d}{dx}(5x+2))=-2(5x+2)^{-3}(5)=-10(5x+2)^{-3}$

so
$\frac{d}{dx}(2x+5)^4(5x+2)^{-2}=8(2x+5)^3(5x+2)^{-2}+(-10(5x+2)^{-3})(2x+5)^4)$

Answer:

<h2>9.1 inches</h2>

Step-by-step explanation:

1cm = 0.3937007874 inches.

As there are 2.54cm in an inch, to convert your cm figure to inches you need to divide your figure by 2.54.

9.05512 -> 9.1 inches

When temperature is zero degree Celsius, the Fahrenheit temperature is 32. When the Celsius temperature is 100, the correspondin

7nadin3 [17]

Answer:

$\\ y = 1.8(x) + 32$ or $\\ y = \frac{9}{5}(x) + 32$

or equivalently:

$\\ F = 1.8(C) + 32$ or $\\ F = \frac{9}{5}(C) + 32$

Step-by-step explanation:

To express the Fahrenheit temperature as a linear function of the Celsius temperature, F(c), we can proceed as follows.

We can use here the two-point form equation of a line:

$\\ y-y_1 = \frac{y_2 - y_1}{x_2 - x_1}(x-x_1)$ [1]

We are asked to express the Fahrenheit temperature as a function of Celsius temperature, so the independent variable, in this case, is x (Celsius temperature) and the dependent variable is y (Fahrenheit temperature).

When temperature is zero degree Celsius ( $\\x_1 = 0$ ), the Fahrenheit temperature is 32 ( $\\y_1 = 32$ ).
