Verify the identity algebraically:<br> Csc(-x)tanx =-secx

weqwewe [10]

Step-by-step explanation:

Recall that

$\sin(-x) = -\sin x$

Therefore,

$\csc(-x) = \dfrac{1}{\sin(-x)} = -\dfrac{1}{\sin x}$

so

$\csc(-x)\tan x = \left(-\dfrac{1}{\sin x}\right)\left(\dfrac{\sin x}{\cos x}\right)$

$\:\:\:\:\:\:\:\:\:= -\dfrac{1}{\cos x} = -\sec x$

Find the volume of this cylinder.

Lina20 [59]

Answer:

The answer is 3418.1 ft rounded to the nearest tenth.

Step-by-step explanation:

The total volume of the cylinder can be defined by the Area of circular base * Perpendicular height.

The area of the circular base can be calculated as

$\pi \times {r}^{2}$

where r is the radius of the circular base, which is 8 ft.

The area of the circular base is

$\pi \times {8}^{2} = 64\pi$

We also know the height of the cylinder is 17 ft.

Hence, the volume of the cylinder is

$64\pi \times 17 = 1088\pi = 3418.0528...$

This will be rounded up to 3418.1 with the nearest tenth
