k0ka [10]

  • <em>I am assuming the picture is of a stained glass window in the shape of a semicircle</em>.

Answer: 7.71 feet.

Step-by-step explanation: <em>The formula for finding the circumference of a circle is \frac{1}{2} π × d + d.</em>

The diameter is 3 feet. Substitute this into the equation:

\frac{1}{2} π × 3 + 3.

Solve -

3.14 × 3 = 9.42

\frac{1}{2} of 9.42 = 4.71

4.71+3 = 7.71

Round -

The answer is already rounded.

Hope this helped!~

What is the correct inverse function for f(x)=ln(3x)?
Maslowich

Let y = f(x)

y = ln(3x)

Exchange place with x and y.

x = ln(3y)

Solve for y.

y = (e^x)/3

Replace y with the inverse notation.

f^(-1) x = (e^x)/3

Done.

What is the slope of the line with the equation x+1=-y?
dusya [7]

The slope intercept form of a line is given by:

\begin{gathered} y=mx+b \\ \text{where:} \\ m=\text{slope} \\ b=y-\text{intercept} \end{gathered}

rewrite the equation in its slope intercept form:

\begin{gathered} x+1=-y \\ \text{ Multiply both sides by -1:} \\ -1(x+1)=-1(-y) \\ y=-x-1 \\ m=-1 \\ b=-1 \end{gathered}

Therefore, the slope is -1

----------------------------------------------------------

using the above procedure:

\begin{gathered} 9x=6+6y \\ \text{subtract 6 from both sides:} \\ 9x-6=6+6y-6 \\ 9x-6=6y \\ \text{divide both sides by 6:} \\ \frac{6y}{6}=\frac{9x-6}{6} \\ y=\frac{3}{2}x-1 \\ m=\frac{3}{2} \\ b=-1 \end{gathered}
