The expression will be undefined when x= -6 and 1/2.
Answer:
Step-by-step explanation:
Keep in mind that these three trig functions can be interpreted as being the ratios of the side lengths of a triangle:
opposite side
sin x = ----------------------
hypotenuse
adjacent side
cos x = ----------------------
hypotenuse
opposite side
tan x = ----------------------
adjacent side
In the case where you have a right triangle and know the lengths of two of its three sides, that knowledge dictates which of the above trig functions to use in "solving the triangle."
------------------------------------------------------------------------------------------------------------
If, for example, the "opposite side" of a triangle is 3 and the "hypotenuse" is 5, we'd choose to use the sine function to find the angle opposite the "opposite side:"
opposite side 3 units
sin x = ---------------------- = -------------
hypotenuse 5 units
Find x by using the inverse sine function:
Angle x = arcsin 3/5 = 0.644 radians or 36.9 degrees.
Answer:

Step-by-step explanation:




Replace h(x) first

Now we plug in 3x in f(x)

Now we plug in 15x-4 in g(x)

$25 well i just divided 1.2 million by 48,000 and got 25.
The answer is -10
hope that helps
