The train travels 70 miles per hour
Answer:
True
Step-by-step explanation:
In order for a relation (a set of ordered pairs) to be considered a <em>function</em>, every value in the <em>domain</em> (the set of all the first numbers in the pair) is associated with one value in the <em>range</em> (the set of all second numbers in the pair). This is easiest to see visually. Our domain is the set {2, 3, 4, 5} and our range is the set {4, 6, 8, 10}, and we can visualize the ordered pair (2, 4) as an "arrow" starting a 2 in the domain and ending at 4 in the range. When seen this way, a relation is a function if <em>every value in the domain only has one arrow coming out of it</em>. We can see from the attached picture that the ordered pairs in the problem are a function, so this statement is true.
Answer:
The equation of the line would be y = -1/2x + 13/2
Step-by-step explanation:
In order to get the slope of the line, you need to first find the slope of the original line. You do this by solving for y.
2x - y = 8
-y = -2x + 8
y = 2x - 8
Now that you have the slope, we take the opposite and reciprocal slope to be the perpendicular (based on the definition of perpendicular lines). This means we take the opposite of 2 (which is -2) and then we flip the term (which means -2 becomes -1/2).
To find the slope-intercept form, we'll use our new slope of -1/2 and a point in point-slope form and solve for y.
y - y1 = m(x - x1)
y - 2 = -1/2(x - 9)
y - 2 = -1/2x + 9/2
y = -1/2x + 13/2
Answer:
If im not wrong, the correct answer is 752.4cm cube
Step-by-step explanation:
First, we find volume of hemisphere, then find the volume of the cone, once we get those, we add them together and find our final answer. I hope this helps :)
