Complete the point slope equation of the line through (-8,-8) &' (-7,9) y-9=

hram777 [196]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ -8 &,& -8~) 
% (c,d)
&&(~ -7 &,& 9~)
\end{array}
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{9-(-8)}{-7-(-8)}\implies \cfrac{9+8}{-7+8}
\\\\\\
\cfrac{17}{1}\implies 17
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_2= m(x- x_2)}\implies y-9=17[x-(-7)]
\\\\\\
y-9=17(x+7)$

If fan is fully open, what is the approximate area of the fan? Answer choices are attached.

scoundrel [369]

Answer:

Option B. $78.8\ in^2$

Step-by-step explanation:

step 1

Find the area of a circle with radius 8.5 inches

The area of a circle is equal to

$A=\pi r^{2}$

substitute

$A=\pi (8.5)^{2}$

$A=72.25\pi\ in^2$

step 2

Find put the approximate area of the fan

we know that

The area of complete circle subtends a central angle of 360 degrees

using proportion

Find the area that correspond a central angle of 125 degrees

$\frac{72.25\pi}{360^o}=\frac{x}{125^o}\\\\x=72.25\pi(125^o)/360^o\\\\x=25.09\pi\ in^2$

assume

$\pi =3.14$

$25.09(3.14)=78.8\ in^2$
