Answer:

Angle BAC corresponds with side length BC

Side length AC will correspond with angle ABC

Step-by-step explanation:

In a triangle, the side length will correspond to the angle opposite it and vice versa.

That is, the side length opposite angle A corresponds to the side of Angle A

Hence, in the triangle given above ;

Angle BAC corresponds with side length BC, because BC is opposite BAC

Side length AC will correspond with angle ABC, because AC is directly opposite angle ABC.

Differentiate y = 8x/ 3 − tan(x)

vagabundo [1.1K]

Answer:

$\frac{dy}{dx}=\frac{8(xsec^2(x)-tan(x)+3)}{(3-tan(x))^2}$

Step-by-step explanation:

$y=\frac{8x}{3-tan(x)}\\ \\\frac{dy}{dx}=\frac{(3-tan(x))(\frac{d}{dx}8x)-(\frac{d}{dx}(3-tan(x)))(8x)}{(3-tan(x))^2}\\ \\ \frac{dy}{dx}=\frac{(3-tan(x))(8)-(-sec^2(x))(8x)}{(3-tan(x))^2}\\ \\ \frac{dy}{dx}=\frac{24-8tan(x)+8xsec^2(x)}{(3-tan(x))^2}\\ \\ \frac{dy}{dx}=\frac{8xsec^2(x)-8tan(x)+24}{(3-tan(x))^2}\\\\ \frac{dy}{dx}=\frac{8(xsec^2(x)-tan(x)+3)}{(3-tan(x))^2}$

Knots are a unit of speed used for sailing. 1 knot is equal to 1.2 miles per hour. Jesse travels 15 miles by boat in 2.5 hours.

Alinara [238K]

Answer:

5 knots

Step-by-step explanation:

In order to find the speed Jesse travels in knots, you need to find his unit rate, or miles per hour. Setting up a fraction and dividing will give you how many miles her traveled per hour:

$\frac{miles}{hour}=\frac{15}{2.5}=\frac{6}{1}or6mph$

Since Jesse traveld at 6mph, you can set up a proportion (equivalent ratios) using the ratio of 1 knot to 1.2 miles per hour to find the number of knots in 6mph:

$\frac{1.2}{1}=\frac{6}{x}$ where x = the number of knots

cross-multiply and divide: 1.2x = 6 or x = 5 knots
