a water storage tank is in the shape of a hemisphere. If the radius is 29ft, approximate the volume of the tank in cubic feet

Step-by-step explanation:

Volume of a hemisphere is given by

where r is the radius of the hemisphere

From the question

r = 29 ft

Substitute the value of r into the formula

That's

We have the final answer as

Hope this helps you

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
