\frac{y}{5}-9=11
Isolate y-terms:
\frac{y}{5}-9+9=11+9
\frac{y}{5}=18
Isolate 'y':
\frac{y}{5}5=18\times 5
y=90

At what points on the graph of f(x)=2x^3-6x^2-27x is the slope of the tangent line -9?
Dmitriy789 [7]

Answer:

(-1, 19) and (3, -81)

Step-by-step explanation:

f(x) = 2x³ − 6x² − 27x

f'(x) = 6x² − 12x − 27

-9 = 6x² − 12x − 27

0 = 6x² − 12x − 18

0 = x² − 2x − 3

0 = (x + 1) (x − 3)

x = -1 or 3

f(-1) = 19

f(3) = -81

The points are (-1, 19) and (3, -81).

What is the surface area of a conical (cone) grain storage tank that has a height of 24 meters and a diameter of 16 meters?
nirvana33 [79]
Surface area of cone is a sum of surface of its base and surface of its mantle.

Surface of its base is a circle which surface we will calculate like this:
Sb = pi*r^2     where r is d/2
Sb = 201m^2

Surface of mantle we calculate by:
Sm = pi*l*r    where l is length of side of cone.

l = \sqrt{r^2 + H^2} = 25.3
Sm = 635.8m^2

Total suface is:
Sb + Sm = 836.8m^2
