Write the equation of the line that passes through the points (-6, -9) and (7, 7).

Rus_ich [418]

Answer:

$\displaystyle y + 9 = \frac{16}{13} ( x + 6 )$

Step-by-step explanation:

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Where m is the slope and (h,k) is a point through which the line passes.

Given a line passes through points A(x1,y1) and B(x2,y2), the slope can be calculated with the equation:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

We are given the points (-6,-9) and (7,7), thus the slope is:

$\displaystyle m=\frac{7+9}{7+6}=\frac{16}{13}$

Now we apply the point-slope formula using the point (-6,-9):

$\mathbf{\displaystyle y + 9 = \frac{16}{13} ( x + 6 )}$

This equation is expressed in the required format

Find the value of $x$ that maximizes $$f(x) = \log (-20x + 12\sqrt{x}).$$ If there is no maximum value, write "NONE".

kakasveta [241]

The function is written as:
f(x) = log(-20x + 12√x)
To find the maximum value, differentiate the equation in terms of x, then equate it to zero. The solution is as follows.

The formula for differentiation would be:
d(log u)/dx = du/u ln(10)
Thus,
d/dx = (-20 + 6/√x)/(-20x + 12√x)(ln 10) = 0
-20 + 6/√x = 0
6/√x = 20
x = (6/20)² = 9/100

Thus,
f(x) = log(-20(9/100)+ 12√(9/100)) = 0.2553

<em>The maximum value of the function is 0.2553.</em>
