Answer:
38
Step-by-step explanation:
To find the radius of a circle you multiply the diameter by 38
(to find the diameter, you divide the radius by 2)
Answer:
2/8 and 5/8
Step-by-step explanation:
4=2×2
8=2×2×<em>2</em>
<em>LCM=</em>2×2×<em>2</em>=8
1/4 × 2/2 = 2/8
Answer:
32.40
Step-by-step explanation:
81 x 40% =48.60
81. -48.60 = 32.40
In Problem 13, we see the graph beginning just after x = -2. There's no dot at x = -2, which means that the domain does not include x = -2. Following the graph to the right, we end up at x = 8 and see that the graph does include a dot at this end point. Thus, the domain includes x = 8. More generally, the domain here is (-2, 8]. Note how this domain describes the input values for which we have a graph. (Very important.)
The smallest y-value shown in the graph is -6. There's no upper limit to y. Thus, the range is [-6, infinity).
Problem 14
Notice that the graph does not touch either the x- or the y-axis, but that there is a graph in both quadrants I and II representing this function. Thus, the domain is (-infinity, 0) ∪ (0, infinity).
There is no graph below the x-axis, and the graph does not touch that axis. Therefore, the range is (0, infinity).
