Write an equation that shows the relationship in this table 1,50 2,100 3,150 4,200

konstantin123 [22]

Answer:

x₁ = 15 xₙ = x₁ * 7 * n n>1

Step-by-step explanation:

150

2100 = 150 x 7 x 2

3150 = 150 x 7 x 3

4200 = 150 x 7 x 4

x₁ = 150

xₙ = x₁ * 7 * n n>1

Differentiating a Logarithmic Function In Exercise, find the derivative of the function.

sleet_krkn [62]

Answer:

$\frac{d}{dx} (ln(e^{x^2}) ) = \frac{1}{e^{x^2}} 2x e^{x^2} = 2x$

Step-by-step explanation:

For this case we want to find the derivate of this function:

$y = ln(e^{x^2}) )$

And in order to find the derivate we need to apply the chain rule given by:

$\frac{df(u)}{dx} =\frac{df}{du} \frac{du}{dx}$

And on this case $f = ln(u), u = e^{x^2}$

And we can find the partial derivates like this:

$\frac{d}{du} (ln(u)) =\frac{1}{u}$

$\frac{d}{dx}(e^{x^2})= e^{x^2} (2x)$

And if we replace we got:

$\frac{d}{dx} (ln(e^{x^2}) ) = \frac{1}{u} 2x e^{x^2}$

And if we replace $u = e^{x^2}$ we got:

$\frac{d}{dx} (ln(e^{x^2}) ) = \frac{1}{e^{x^2}} 2x e^{x^2} = 2x$

And that would be our final answer on this case

Step-by-step explanation:

A ratio can be expressed in words as a description, with a colon between 2 quantities, or as a fraction.

EXPLANATION:

A ratio is a statement of the quantitative relationship between two numbers in a given scenario.

- It can be expressed in words as a description of the relationship. E.g. "Ratio 2 to 8"

- It can be expressed with a colon. E.g. "2:8"

- It can be expressed as a fraction. E.g. "2/8"
