Answer:

slope = $\frac{1}{-3}$

Step-by-step explanation:

equation to find the slope: $\frac{y1-y2}{x1-x2}$

(0,4) (6,2)

$\frac{4-2}{0-6}$ = $\frac{2}{-6}$ = $\frac{1}{-3}$

Below is the graph of f(x)=2In(x). how would you describe the graph of g(x)=4In(x)

$\bf \qquad \qquad \qquad \qquad \textit{function transformations}
\\ \quad \\\\

\begin{array}{rllll} 
% left side templates
f(x)=&{{ A}}({{ B}}x+{{ C}})+{{ D}}
\\ \quad \\
y=&{{ A}}({{ B}}x+{{ C}})+{{ D}}
\\ \quad \\
f(x)=&{{ A}}\sqrt{{{ B}}x+{{ C}}}+{{ D}}

$\bf \begin{array}{llll}

\end{array}$

now... with that template in mind, let's see yours

$\bf \begin{array}{llll}
g(x)=&4ln(x)\implies &2(2)ln(x)\\
&\uparrow &\uparrow \\
&A&A
\end{array}$

A is twice as large as in f(x), thus the graph shrinks twice as much in g(x)

Yolanda is filling her bathtub. The table shows the number of gallons of water in the bathtub at different times since she start

Gelneren [198K]

Answer:

K= 16.5 gallons per minute

Step-by-step explanation:

Time t (minutes) Water g (gallons)

For t= 1, g= 16.50,

for t= 1.5 ,g= 24.75

For t= 2,g= 33

Let the function be

Gallons g= k(time t)

Where k is the constant of proportionality

16.5= k(1)for when t= 1

24.75= k(1.5) ..for when t= 1.5

Solving gives

8.25=k(0.5)

8.25/0.5= k.

16.5 = k

K= 16.5 gallons per minute

Area=<br> Help please!! Asap thank u so much

The area of the shaded region in the task content is; 251.2.

<h3>What is the area of the shaded region in the task content?</h3>

It follows from the task content that the area of the shaded region is;

= Area of semicircle IL - Area of semicircle JK + Area of semicircle IJ + Area of semicircle KL.

Hence, since the radius of each semicircle are as follows;

R(IL) = 12

R(IJ) = R(JK) = R(KL) = 4.

Hence, the Area of the shaded region can be evaluated as;

= (π/2)(12² - 4² + 4² +4²).

= π (144 +16)

= (3.14/2) × 160 = 251.2
