Tính đạo hàm của y=2x-1-căn3x-0

Mathematics
1 answer:
adoni [48]3 years ago
7 0

Answer:

The derivative is

\frac{dy}{dx} = 2 -  \frac{2\sqrt3}{\sqrt x}\\

Step-by-step explanation:

The function is given by

y = 2x - 1 - \sqrt {3x}

Differentiate with respect to x, we get

\frac{dy}{dx} = 2 - 0 - \frac{2\sqrt3}{\sqrt x}\\\\\frac{dy}{dx} = 2 -  \frac{2\sqrt3}{\sqrt x}\\

A can of tuna fish is a cylinder with a height of 1.75 inches and a diameter of 3 inches. If the can is half full, how many cubi
zlopas [31]

Answer: 6.185in^3

Step-by-step explanation:

The formula for calculate the volume of a cylinder is:

V_{cylinder}=\pi r^2h

r is the radius of the cylinder and h is the height of the cylinder.

Given the diameter of 3 inches, calculate the radius of the cylinder with:

r=\frac{d}{2} (Where d is the diameter)

 r=\frac{3in}{2}=1.5in

Knowing the height and the radius, you can calculate the volume of the entire can of tuna:

V_{can}=\pi (1.5)^2(1.75in)=12.37in^3

As you want to know the cubic inches of tuna that are in the can (volume of tuna), and you know that the can is half full, then:

V_{tuna}=\frac{V_{can}}{2}\\\\V_{tuna}=\frac{12.37in^3}{2}\\\\V_{tuna}=6.185in^3
