Answer:

14130 ft^3

Step-by-step explanation:

The formula for the volume of a cone of radius r and height h is

V = (1/3)*pi*r^2*h.

Here, V = (1/3)(3.14)(15 ft)^2*(60 ft) = 20*3.14*225 ft^3 = 14130 ft^3

What numbers add up to -5 and multiply to get -90

Molodets [167]

Let
x-------> the first number
y-------> the second number

we know that

$x+y=-5 \\ x=-5-y$ equation 1

$x*y=-90$ equation 2

substitute the equation 1 in equation 2

$[-5-y]*y=-90 \\ -5y- y^{2} =-90 \\ y^{2} +5y-90=0$

using a graphical tool to resolve the second order equation
see the attached figure
the numbers are

The point (-3/5,y) in the third quadrant corresponds to angle θ on the unit circle.

romanna [79]

Sec(theta) = 1 / cos (theta) = hypotenuse / x -coordinate

hypotenuse = 1 (because it is the radius of the unit circle)

sec (theta) = 1 / (-3/5) = - 5/3

cot (theta) = 1 / tan(theta) = x-coordinate / y - coordinate

cot (theta) = -3/5 / y

y^2 + (-3/5)^2 = 1 => y^2 = 1 - 9/25 = 16/25 = y = +/- 4/5

Third quadrant => y = -4/5

=> cot (theta) = (-3/5) / (-4/5) = 3/4
