Answer:
-csc²θ(tan²θ)
Step-by-step explanation:
csc²θ-csc²θ(sec²θ)
-csc²θ(-1+sec²θ)
-csc²θ(tan²θ)
Answer:
The y intercept is -21
Step-by-step explanation:
y = (x - 3)(x + 7)
To find the y intercept, set x =0 and solve for y
y = (0-3) (x+7)
y = -3*7
y = -21
The y intercept is -21
Answer:
C. -8
Step-by-step explanation:
-2^4 = 16
-2^-1 = -1/2
Answer:
XW = 4 units
Step-by-step explanation:
Given tanf° =
, then
tanf° =
=
=
=
( cross- multiply )
2XW = 8 ( divide both sides by 2 )
XW = 4
