Identify each expression that represents the slope of a tangent to the curve y=1/x+1 at any point (x,y) .

tankabanditka [31]

Answer:

Slope of a tangent to the curve = $f'(x) = \frac{-1 }{(x+1)^{2} }$

Step-by-step explanation:

Given - y = 1/x+1

To find - Identify each expression that represents the slope of a tangent to the curve y=1/x+1 at any point (x,y) .

Proof -

We know that,

Slope of tangent line = f'(x) = $\lim_{h \to 0} \frac{f(x+h) - f(x)}{h}$

We have,

f(x) = y = $\frac{1}{x+1}$

So,

f(x+h) = $\frac{1}{x+h+1}$

Now,

Slope = f'(x)

And

$f'(x) = \lim_{h \to 0} \frac{f(x+h) - f(x)}{h} \\= \lim_{h \to 0} \frac{\frac{1}{x+h+1} - \frac{1}{x+1} }{h}\\= \lim_{h \to 0} \frac{x+1 - (x+h+1) }{h(x+1)(x+h+1)}\\= \lim_{h \to 0} \frac{x +1 - x-h-1 }{h(x+1)(x+h+1)}\\= \lim_{h \to 0} \frac{-h }{h(x+1)(x+h+1)}\\= \lim_{h \to 0} \frac{-1 }{(x+1)(x+h+1)}\\= \frac{-1 }{(x+1)(x+0+1)}\\= \frac{-1 }{(x+1)(x+1)}\\= \frac{-1 }{(x+1)^{2} }$

∴ we get

Slope of a tangent to the curve = $f'(x) = \frac{-1 }{(x+1)^{2} }$

Hunter-Best [27]

Answer:

1.2144xx

Step-by-step explanation:

The multiplier of value for the first year was (1 +38%) = 1.38.

The multiplier of value for the second year was (1 -12%) = 0.88.

Then the multiplier of value for the two years was ...

1.38×0.88 = 1.2144

The value of the stock after 2 years was ...

1.2144xx

_____

<em>Comment on the variable</em>

Which is the simplified form of n Superscript negative 6 p cubed?

evablogger [386]

Answer:

Third option. $\frac{p^3}{n^{6}}$

Step-by-step explanation:

For this exercise you need to remember one of the properties for exponents.

There is a property called the "Negative property of exponents" which states the following:

$b^{-n}=\frac{1}{b^n}$

Where $b \neq0$

As you can observe, $b^n$ is the reciprocal of $b^{-n}$

In this case you have the following expression given in the exercise:

$n^{-6}p^3$

Observe the expression. As you can notice, the base "n" has a negative exponent, which is -6.

Therefore, applying the Negative property of exponents explained at the beginning of this explanation, you can simplify the expression.

Then, the simplified form of $n^{-6p^3}$ is the one shown below:

$n^{-6}p^3=\frac{p^3}{n^{6}}$

Write −1/2x+y=10 in slope-intercept form.

Varvara68 [4.7K]

Answer:

$y=\frac{1}{2} x+10$

Step-by-step explanation:

$-\frac{1}{2} x+y=10\\$

<em>Add </em> $\frac{1}{2} x$ <em> to both sides</em>

$y=10+\frac{1}{2} x\\\\y=\frac{1}{2} x+10$
