So um basically it appears to be 30%
Answer:
Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x2+3 f - 1 ( x ) = x 2 + 3 is the inverse of f(x)=2x−6 f ( x ) = 2 x - 6 .
Step-by-step explanation:
Answer:
C(-31)
Step-by-step explanation:
= 5 - 4(1 + 2^3)
= 5 - 4(1 + (2 . 2 . 2))
= 5 - 4(1 + (4 . 2))
= 5 - 4(1 + 8)
= 5 - 4(9)
= 5 - 36
= (-31)
OPTION C
Answer:
Option A
Step-by-step explanation:
It's given that cosθ = 
Since, cosθ =
= 
= 
By applying Pythagoras theorem in the right triangle,
(Hypotenuse)² = (Opposite side)² + (Adjacent side)²
(√5)² = (Opposite side)² + (2)²
5 = (Opposite side)² + 4
Opposite side = √(5 - 4)
= 1
Since, sinθ = 
= 
Since, sine is positive in IInd quadrant,
sinθ = 
Therefore, option A will be the answer.
Answer:
$71.20
Step-by-step explanation:
Multiply 89 to .2 and you get 17.8 then you subtract that from the originat cost.
