The value of the expression n° +5n² + 5n -2 when n=-2 is?​

question seems to be improper

Step-by-step explanation:

but, if n^0 is there, It is equal to 1

so here the solution goes

1+5(-2)^2+5(-2)-2

=> 1+20-10-2

=>9 ans

= 3 +5n² An- 3

Step-by-step explanation:

V = 200 π

Step-by-step explanation:

x = 5√y ,   x = 0 ,   y = 4

Determine the volume of the solid V

when x = 0  y = 0

we can calculate the volume of the solid by applying the washer method

V = π ₀⁴∫ [ 0 + ( 5√y )^2 ]  dy

   = π ₀⁴∫ [ 0 + ( 25(y) ) ]  dy

V  = π [ 0 + 25/2 ( y^2 ) ] ⁴₀

V = π [ 25/2 ( 16 ) ]

  = 200 π
