Find dy/dx of y=csc(square root of x)

Vitek1552 [10]

Answer:

$y' = -\dfrac{\cot x \csc x}{2 \sqrt{x}}$

Step-by-step explanation:

y = csc x

y' = -cot x csc x

$y = \csc \sqrt{x}$

$y' = \dfrac{d}{dx} [\csc \sqrt{x}]$

$y' = (-\cot x \csc x) \dfrac{d}{dx} \sqrt{x}$

$y' = (-\cot x \csc x) \dfrac{d}{dx} x^{\frac{1}{2}}$

$y' = (-\cot x \csc x) \dfrac{1}{2} x^{-\frac{1}{2}}$

$y' = -\dfrac{\cot x \csc x}{2 \sqrt{x}}$

A rectangular tank measures 16 cm by 9 cm by 10 cm. How many milliliters of water are in the tank when it is full? How many lite

trapecia [35]

Answer:

1,440 cubic centimeter = 1,440 milliliters

1,440 cubic centimeter= 1.44 liters

Step-by-step explanation:

Volume of the rectangular tank = length × width × height

Length = 16 cm

Width = 9 cm

Height = 10 cm

Volume of the rectangular tank = length × width × height

= 16 cm × 9 cm × 10 cm

= 1,440 cm³

Volume of the rectangular tank = 1,440 cm³

How many milliliters of water are in the tank when it is full?

1 cubic centimeter = 1 milliliter

1,440 cubic centimeter = 1,440 milliliters

How many liters?

1 cubic centimeter = 0.001 liters

1,440 cubic centimeter= 1.44 liters

Answer:

201 miles.

Step-by-step explanation:

If you've traveled 124 miles in 2 hours, than in one hour must've been 62 miles. 62 multiplied by 3 is 186, which is how much miles have been traveled in 3 hours. Plus the 15 minutes would probably be 201 miles. Hope this helps!
