Answer: Choice B) -infinity < x < infinity
==========================================================
Explanation:
The parabola goes on forever to the left and to the right. We can plug in any x value without worrying about something as a division by zero error. So any real number will work.
Writing -infinity < x < infinity refers to the entire number line, which is the set of all real numbers.
Answer:
Height 4 ft
Step-by-step explanation:
Surface area= 2(lw + lh + wh) =
2(16)16)+2(16h)+2(6h) =
2(16)(6)+32h+12h=368
192 + 44h = 368
44h = 368 - 192
44h = 176
h = 176/44
Assuming that says a² + B² and not a² ÷ B², your answer would be 5.
To answer this question you need to find the value of a and B, which you can do by finding the roots of x² - 3x + 2 = 0. You can do this by factoring the equation to get (x - 2)(x - 1) = 0, and so x = 2 or x = 1.
Then, we just need to square 2 and 1, and add them, giving us 4 + 1 = 5.
I hope this helps!
Why not draw the graph of y=|x|? It has a v-shape, and the vertex is at (0,0).
The graph of f(x) = |x| - 3 looks exactly the same, EXCEPT that the whole graph of |x| is shifted 3 units downward. The smallest value that y can have is therefore -3.
Can you now figure out the range of f(x)?
A =>180-37=143
b=>90-37=53
c=90-53=37
