Answer:
d
Step-by-step explanation:
If x represents the slant height, the graph would be a straight line.
If x represents the radius, the graph would be a parabola.
Looking at the answers, we're looking for x to be the slant height, so we're looking for a straight line.
We are looking for g(x). Answers a and b are wrong.
In g(x) r is fixed to 5 (this is given). So the slant height in the smallest possible cone would still be at least 5.
So the domain is x > 5.
d is your answer.
Step-by-step explanation:
the area is
length × width
(3x - 2) × width = 9x² - 4
to find width we could do a real polynomial division or simply recognize the fact that
(a + b)(a - b) = a² - b²
and we see that in our area calculation we are missing the (a + b) factor.
so, width = (3x + 2)
but if you want the division :
9x² - 4 : 3x - 2 = 3x + 2
- 9x² - 6x
-----------------
0 6x - 4
- 6x - 4
----------------------
0 0
again, width = (3x + 2)
Answer:
Plot a point at (0,-3) and (2,-2) then connect.
Step-by-step explanation:
Use y=mx +b to guide where you graph the line. b is the y -intercept and shoud be graphed on the y-axis. m represents the slope which is rise/run. To graph the line, mark -3 on the y-intercept. Then plot the next point 1 unit up and 2 units over at (2, -2).
