Answer:

The point ( 0,-1) is a solution.

Step-by-step explanation:

y<= (x+1) (x+5)

y>= (x-1)^2 -6


See attached graph.


To prove algebraically, put the point (0,-1) into both equations and see if it is true for both of them.

y<= (x+1) (x+5)

-1 <= (0+1) (0+5)

-1<= 1*5

-1 <=5

True

y>= (x-1)^2 -6

-1 >= (-1)^2 -6

-1 >= 1-6

-1 >=-5

True

The point is a solution

Acone has a height of 7 ft and a radius of 4 ft. Which equation can find the volume of the cone?
Marina86 [1]

Answer:

Volume of the cone = 117.06\,feet^3

Step-by-step explanation:

Height of the cone = 7\,feet

Radius of the cone = 4\,feet

Volume of a cone is:

              \pi \times r^2\times \dfrac{h}{3}

As, \pi =\dfrac{22}{7} =3.14

Volume is:      

                 =3.14\times(4\times 4)\times \dfrac{7}{3}\\\\ =3.14\times 16 \times 2.33\\\\=3.14\times 37.28\\\\=117.06\,feet^3

The volume of the cone is: 117.06\,feet^3
