The basic form of the equation of a circle is:
x^2+y^2=r^2
where r^2 is the radius squared.
Looking at your equation, x^2+y^2=9, the radius is 3 (sqrt of 9 is 3)
Therefore, the graph B would be correct since the radius of the circle at all points is 3.
Hope I helped :)
Step-by-step explanation:
Area of the octagon = 2(1+√2)8=309.02 units
Let the present worth = P
P(1+0.075)^8 = 1,00,000
⇒ 1.783478 P = 100000
⇒ P = 100000/1.783478
⇒ P = $56,070
Answer:
the answer is 13. 6 is the correct answer
Answer:
REALS. all real numbers are solution for the equation
Step-by-step explanation:
for the equation
x² = (x + 3)*(x − 3) + 9
distributing the terms in the parenthesis
x² = (x + 3)*(x − 3) + 9 = [x² - 3*x + 3*x - 3*3 ] + 9
x² = x² - 9 + 9
0 = 0
since this statement will be true regardless of the value of x , then the equation has solution for all real numbers .
