Answer:
A
Step-by-step explanation:
Using the co function identity
sin x = cos(90 - x) = cos(90 - 30) = cos60° ← x = 30°, thus
sin30° = cos60°
Answer:
Inverse of F(x)=9x = 1/9x
Step-by-step explanation:
If F(x)=9x
which of the following is the inverse of F(x)
When talking about inverse of a function, we are talking about reversal. Therefore, an inverse function is the inverse of another function. In order to get the inverse of a particular function, we reverse the denominator to become the numerator and the numerator to become the denominator.
So for the function,
F(x)=9x, the numerator is 9x and the denominator is 1
Reversing the numerator and denominator, .
Inverse of F(x)=9x = 1/9x
Answer:
$319.60
Step-by-step explanation:
Normal Game console cost : $399.50
Discount: %20 (0.20)
$399.50×0.20= $79.90
Total cost of discount $79.90
$399.50-$79.90= $319.60
New cost after Discount= $319.60
