Which trigonometric functions have a domain of [-1, 1]? y = arcsinx and y = arccosx
y = arccosx and y = arctanx
y = arcsinx and y = arctanx
y = arcsecx and y = arccscx

step-by-step explanation:

kjswgdkxg

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

combine all like terms then its just a 2 step equation
