Answer:
surface area we can also take it as total surface area
9 is the radius and 5cm is the height . as they asked total surface area we have to take the area of base so tht we can make it as
total surface area = csa of cylinder + area of base
we know that,
2pirh+pir²
pir(2h+r)
pir(2×5+9)
pir(10+9)
pir(19)
22/7×9×19
3762/7
=> 537.42 cm² is the answer.
F(x)=x^3-7x-6 Since I don't have the graph and this is not a perfect cube, I will have to rely on Newton :P
x-(f(x)/(dy/dx))
x-(x^3-7x-6)/(3x^2-7)
(2x^3+6)/(3x^2-7), letting x1=0
0, -6/7, -.988, -.9999, -.99999999999, -1
(x^3-7x-6)/(x+1)
x^2 r -x^2-7x-6
-x r -6x-6
-6 r 0
(x+1)(x^2-x-6)=0
(x+1)(x-3)(x+2)=0
x= -2, -1, 3
Hello there.
<span>How to solve -2 = -6 + 4v?</span>
<span><span>−2</span>=<span><span>4v</span>−6</span></span>
