N circle C, r = 32 units. What is the area of circle C?
charle [14.2K]
The answer is:  " 1024π units² " ; or;  " 3215.36 units² " .
______________________________________________________
A = π * r²  ;

A = π * 32² = 1024 π units² ;

 or, using "3.14" for "π" ;

1024 * π = 1024 * (3.14) = 3215.36 units² .

Given 5n² + 6n + 7 = n² - 4n : a. Find the value of the discriminant. b. State the number and type of roots/solutions/zeros.[2 r
Vika [28.1K]
\bf 5n^2+6n+7=n^2-4n\implies 5n^2+6n+7-n^2+4n=0
\\\\\\
4n^2+10n+7=0\\\\
-------------------------------\\\\
\begin{array}{llccll}
&{{ 4}}x^2&{{ +10}}x&{{ +7}}\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}
\\\\\\
discriminant\implies b^2-4ac=
\begin{cases}
0&\textit{one solution}\\
positive&\textit{two solutions}\\
negative&\textit{no solution}
\end{cases}

if you get a positive value, that means 2 real solutions
if you get 0, means 1 real solution only
if you get a negative value, is an imaginary root solution, same as saying no solution.
