Classify the limaçon represented by the equation r=(1/2)-(1/2)sin(theta)
babunello [35]
We know that

Limacons are in the form
r=a(+-)b*sin (theta)  or r=a(+-)b*cos (theta)

in this problem
r=a(+-)b*sin (theta)
so
is symmetric to y axis
a=1/2
b=1/2
a/b=1---------> Cardioid (hearth shaped)

see the attached figure

4-2x=11 how do I solve
Bingel [31]

Hey there!☺

Answer:\boxed{x=\frac{-7}{2}}

Explanation:

4-2x=11

In our first step, we will simplify both sides of the equation:

4+-2x=11\\-2x+4=11

Now subtract 4 from both sides:

-2x+4-4=11-4\\-2x=7

In our last step, we will divide both sides by -2:

\frac{-2x}{2}=\frac{7}{-2}\\  x=\frac{-7}{2}

x=-7/2 is your answer.

Hope this helps!☺

A wire is to be attached to support a telephone pole. Because of surrounding buildings, sidewalks, and​ roadways, the wire must
ad-work [718]
This situation is a right triangle with the base measuring 18 and the hypotenuse 22.  We are looking for x, the height up the pole that the wire is going to be attached to.  We will use Pythagorean's Theorem to find the missing length.  22^2-18^2=x^2  and  484-324=x^2.  x^2 = 160 so x = 4 \sqrt{10} or 12.65 feet
