Answer:
25.920 W
Step-by-step explanation:
Fill in the given number and do the arithmetic.
P = f(12) = 0.015(12^3) = 25.920 . . . . . watts

-2y≤-4x+8
/-2 /-2
y≥2-4
Answer:
It would cost $24 to produce 6 widgets.
Step-by-step explanation:
If you turn the information into points, you can use those three points to find the parabolic function for the graph (it's y=(x squared over 2) -2x +18.) All you have to do then is find where 6 widgets lines up with the graph.
f(x) = 4x + 3
That's one-to-one, a linear function that will give a different f(x) for each different x.
For the inverse let's swap x and y and solve for y
x = 4y + 3
x - 3 = 4y
y = (x- 3)/4
That's the inverse,
Answer: (x- 3)/4, second choice
The domain and range of the inverse is all real numbers. It's two lines; I'll leave the graphing to you.
