Answer:

  8 gallons

Step-by-step explanation:

Each rectangular face of the monument has an area of ...

  A = bh = (9 ft)(39 ft) = 351 ft^2

The triangular face on top of that rectangle has an area of ...

  A = (1/2)bh = (1/2)(9 ft)(10 ft) = 45 ft^2

So, one side of the monument has an area of ...

  one side = (351 ft^2) +(45 ft^2) = 396 ft^2

The total area of all four identical sides is ...

  surface area = (4)(396 ft^2) = 1584 ft^2

__

Each gallon covers 199 ft^2, to the number gallons required is ...

  (1584 ft^2)/(199 ft^2/gal) ≈ 7.96 gal

Since only whole gallons can be purchased, 8 gallons of paint must be bought.

Answer:

a) 25.15

b)

   x = 1

   y = t

   z = (4pi)^2 + t *(8pi) = 4pi(4pi + 2t)

c) (x,y) = (1, -2pi)

Step-by-step explanation:

a)

First lets calculate the velocity, that is, the derivative of c(t) with respect to t:

v(t) = (-sin(t), cos(t), 2t)

The velocity at t0=4pi is:

v(4pi) = (0, 1, 8pi)

And the speed will be:

s(4pi) = √(0^2+1^2+ (8pi)^2) = 25.15

b)

The tangent line to c(t) at t0 = 4pi has the parametric form:

(x,y,z) = c(4pi) + t*v(4pi)

Since

 c(4pi) = (1, 0, (4pi)^2)

The tangent curve has the following components:

x = 1

y = t

z = (4pi)^2 + t *(8pi) = 4pi(4pi + 2t)

c)

The intersection with the xy plane will occurr when z = 0

This happens at:

  t1 = -2pi

Therefore, the intersection will occur at:

(x,y) = (1, -2pi)
