8 0

Answer:

B is the answer

Step-by-step explanation:

A = πr²

24π = πr²

24 = r²

24 = r²

\sqrt{24} = r

r = \sqrt{4}\sqrt{6} = 2\sqrt{6}

C = 2πr

C = 2π(2\sqrt{6})

C = 4\sqrt{6}π

Write the absolute value inequality in the form Ix−bIc that has the solution set x≤−9 or x≥−5.
Valentin [98]

Answer:

\large\boxed{|x+7|\geq2}

Step-by-step explanation:

Look at the picture.

|x-a|\geq b\\\\a=\dfrac{-9+(-5)}{2}=\dfrac{-14}{2}=-7\\\\b=-9-(-7)=-9+7=-2\\b=-5-(-7)=-5+7=2\\\\|x-(-7)|\geq2\\\\|x+7|\geq2\\\\Check:\\\\|x+7|\geq2\iff x+7\geq2\ \vee\ x+7\leq-2\qquad\text{subtract 7 from both sides}\\\\x+7-7\geq2-7\ \vee\ x+7-7\leq-2-7\\\\x\geq-5\ \vee\ x\leq-9\qquad CORRECT\ :)
