What is the name of the shape graphed by the function r = 2 - costheta
Afina-wow [57]

Answer:

limaçon (no inner loop)

Step-by-step explanation:

The equation of a limaçon is written generically as ...

r = b + a·cos(θ)

For b=2 and a=1, this would put the flat side on the left. Rotating it 180° can be accomplished by adding or subtracting π from θ. Then the equation can be ...

r = 2 + cos(θ-π) . . . . or ...

r = 2 - cos(θ)

4.25 -2.5x = 14.75<br> I need help
shtirl [24]

\text {Hey! Let's Solve this Equation!}

\text {\underline {The First Step is to do Keep Change Change (KCC)}}

\text {Keep: 4.25}\\\text {Change: - into +}\\\text {Change: 2.5x into -2.5x}

\text {\underline {The Next Step is to Flip the Equation}}

\text {Before: 4.25+-2.5x=14.75}\\\text {After: -2.5x+4.25=14.75}

\text {\underline {The Next Step is to Subtract 4.25}}

\text {-2.5x+4.25-4.25=14.75-4.25=10.5}\\\text {-2.5x=10.5}

\text {\underline {The Final Step is to Divide -2.5}}

\text {-2.5x/-2.5=10.5/-2.5}

\text {Remember that Dividing a Positive to a Negative will Equal a Negative.}

\text {Your Answer Would Be:}

\fbox {x=-4.2}

\text {Best of Luck!}
