F(x)=2^x+6
let f(x) = n
f^-1(n) = x
x = 2^n + 6
x - 6 = 2^n
2^n = x - 6
log 2^n = log (x-6)
n log 2 = log (x-6)
n = (x-6)/2
f^-1(x) = (x-6)/2
Answer:
A
Step-by-step explanation:
Using the Sine rule in Δ ABC
= , substitute values
= ( cross- multiply )
BC sin38° = 3 sin66° ( divide both sides by sin38° )
BC = → A
Answer:
Step-by-step explanation:
Just because before y there is negative "-" thus youve got to put it before 18. Eventually the answer is -18,not 22
Answer:
A. without changing the setting of the compass, place the point of the compass on point D and drawn out the intersects line L and extends below line L.
Step-by-step explanation:
In the figure attached, the procedure is shown.
In this case, we are at step 2, the first arc was made, and you have to make the second arc (without changing the setting of the compass) placing the point of the compass on point D.
