2 answers:

5 0

The circumferince of the circle is 2πR ;
The area of the circle is π $R^{2}$ ;
Then, 2πR = 704 ;
R = 352 / π ;
π $R^{2}$ = π × ( 352 / π )^2 = ( 352^2) / π = 123904 / π ≈ 39459.87 ≈ 39460 cm^2 ;

If the circumference of a circle is 704 cm, then the area is: 39439.87 cm.

The formula looks like this: A = π r 2 and C = 2 π r.

So, C = 704 cm and A = 39439.87 cm.

Hope I helped!

natta225 [31]

Answer:

The values of k are 2/3 and -1

Step-by-step explanation:

Product of zeros = αβ= constant / coefficient of x^2 = 4/k

Sum of zeros =α+β = - coefficient of x / coefficient of x^2= -4/k

Given

Consider a= α and b= β

$(\alpha)^2 + (\beta)^2 = 24$

$(\alpha)^2 + (\beta)^2$ can be written as $(\alpha)^2 + 2(\alpha)(\beta) + (\beta)^2$ if we add $\pm 2 (\alpha)(\beta)$ in the above equation.

$(\alpha)^2 + 2(\alpha)(\beta) + (\beta)^2 -2(\alpha)(\beta)$

$(\alpha + \beta)^2 -2(\alpha)(\beta)$

Putting values of αβ and α+β

$(\frac {-4}{k})^2 -2( \frac {4}{k}) = 24\\\frac {16}{k^2} - \frac {8}{k} = 24\\Multiplying\,\, the \,\, equation\,\, with\,\, 8K^2\\ 2 - k= 3K^2\\3k^2-2+k=0\\or\\3k^2+k-2=0\\3k^2+3k-2k-2=0\\3k(k+1)-2(k+1)=0\\(3k-2)(k+1)=0\\3k-2=0 \,\,and\,\, k+1 =0\\k= 2/3 \,\,and\,\, k=-1$

The values of k are 2/3 and -1

Anastasy [175]

Answer:

THe value after 5 years will be $301100.755

Step-by-step explanation:

Each year the houses appreciates a 6%; as a result, the price of the house is multiplied by 1.06 for each passing year. If 5 years passed, then the price would multiply for 1.06 a total of 5 times, hence it will be multiplied by 1.06⁵.

The value of the house after 5 years will be

225000*1.06⁵ = $301100.755
