In a circle, a 270degrees sector has area 75pi inches squared. What is the radius of the circle?

1 answer:

6 0

A 270 degree of sector = 0.75 of its area
area = π r²
so,
      0.75 π r² = 75 π

       r² = (75 π)/( 0.75 π) = 100

       r = +√100 = 10
so
    The radius of the circle is 10 in

Problem #1 -Find the equation of the line with the given slope and containing the given point.

DaniilM [7]

For 1)

$\bf \begin{array}{lllll}
&x_1&y_1\\
% (a,b)
&({{ -7}}\quad ,&{{ 0}})\quad 
% (c,d)

\end{array}
\\\quad \\\\ % slope = m
slope = {{\boxed{ m}}}= \cfrac{rise}{run} \implies 
\implies -\cfrac{3}{5}
\\ \quad \\\\
% point-slope intercept
y-{{ y_1}}={{\boxed{ m}}}(x-{{ x_1}})\qquad \textit{plug in the values and solve for "y"}\\
\qquad \uparrow\\
\textit{point-slope form}$

for 2)

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ -3}}\quad ,&{{ 17}})\quad 
% (c,d)
&({{ -7}}\quad ,&{{ 37}})
\end{array}
\\\quad \\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}
\\ \quad \\\\
% point-slope intercept
y-{{ y_1}}={{ m}}(x-{{ x_1}})\qquad \textit{plug in the values and solve for "y"}\\
\qquad \uparrow\\
\textit{point-slope form}$

then change the y= part to f(x) =

To solve this system of equations by elimination, what operation could be used to eliminate the x-variable and find the value of

gayaneshka [121]

The system of equations are:

2x − 4y = 6
−3x + 3y = 9

To eliminate x, you should:
1. multiply first equation with 3
2. multiply second equation with 2
3. add the new equations you got

So your answer is A.
