The height of a triangle is 2 less than 5 times its base. If the base of the triangle is x feet, and the area of the triangle is

mamaluj [8]

Answer:

12 = 1/2(x)(5x - 2)

Bonus solution for x = 2.4 ft

Step-by-step explanation:

area = 1/2xh

h = 5x - 2

12 = 1/2(x)(5x - 2)

24 = 5x² - 2x

5x² - 2x - 24 = 0

x² - 0.4x - 4.8 = 0

(x - 2.4)(x + 2) = 0

x = 2.4

Please help i don't know what I'm doing!!! :( multiply and simplify cot x( sin x - sec x)

fgiga [73]

Answer:

cos(x) -csc(x)

Step-by-step explanation:

It is helpful to know the relations between the trig functions:

$\cot{x}=\dfrac{\cos{x}}{\sin{x}}\\\\\sec{x}=\dfrac{1}{\cos{x}}\\\\\csc{x}=\dfrac{1}{\sin{x}}$

Then the given expression can be simplified as follows:

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