S2=81 solve right answers please really need help

s = +/- 9 or 40.5

If you’re asking what s(2) = 81 is, then you divide both sides by 2 to get 40.5.

If you want s squared = 81, you will be taking the square root of each side so 9.

Step-by-step explanation:

s2=81

Divide both sides by 2

s=40.5

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
