Derivative of csc(x) = $\frac{d}{dx} [csc(x)] = -csc(x)cot(x)$

Step-by-step explanation:

Step 1: Define

$\frac{d}{dx} [csc(x)]\\x = \frac{3 \pi}{2}$

Step 2: Differentiate

Differentiate: $\frac{d}{dx} [csc(x)] = -csc(x)cot(x)$

Step 3: Evaluate

Substitute in x: $-csc(\frac{3 \pi}{2} )cot(\frac{3 \pi}{2} )$
Evaluate: $0$

Find the value of the variable. If the answer is not a whole number, round to the nearest tenth.

r-ruslan [8.4K]

Answer:

Step-by-step explanation:

Two secants drawn to a circle from a common external point, then

The product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is

5(5 + x) = 4(4 + 10) = 4 × 14 = 56

25 + 5x = 56 ( subtract 25 from both sides )

5x = 31 ( divide both sides by 5 )

x = 6.2 → C

Emilio’s pay varies directly with the number of sales he makes. He made 22 sales and earned $154.

Vinil7 [7]

154/22 sales = $7/sale
$7/sale(35 sales) = $245 
He will earn $245 for 35 sales.
