Rewrite as x2 -8x +7 > 0

so, (x-7)(x-1)>0

clearly the product would be >0 either when both are +ve or when both are -ve

both positive⇒x>7
both negative⇒x<1
so, "x<1 and x>7" is the answer

The volume of a sphere is approximately 44.6022 cubic centimeters. What is the radius of the sphere to the nearest tenth of a ce

Mumz [18]

The formula for the volume of a sphere is (4/3)*pi*r^3. Using this formula, we have 44.6022 cm^3 = (4/3)*pi*r^3. Solving for r, we get 2.2 cm. Thus, the radius of the sphere with an approximate volume of 44.6022 cubic centimeters is 2.2 cm. To add, the volume of a sphere is also exactly two-thirds the volume of its circumscribed cylinder.
