The "median" of a set is just the middle value for an odd number of ordered elements or the average of the middle two values for an even number of ordered elements. In this case you are four elements so it would be the average of the second and third terms...
median=(12.5+13.24)/2
median=12.87 (exactly, no rounding needed)
Answer:
a) the point is on the line
b) the lines are the same line
Step-by-step explanation:
a) The distance from a point to a line is zero when the point satisfies the equation of the line. That is, the point is on the line.
b) Two lines are zero distance apart when they are on top of each other, indistinguishable. That is, they are the same line.
Answer:
The rate of change: 1/5
Initial value: (0,-1)
Step-by-step explanation:
The rate of change is easily 5/25, we just have to simplify it to 1/5.
To get the intial value, just subtract (2,9) by the rate of change twice.
Answer:
28 x^3
Step-by-step explanation:
4x(7x^2)
4 * x* 7* x*x
4*7 x*x*x
28 x^3
Answer:
22/10 or 2 and 1/5
Step-by-step explanation:
To find the perimeter, add all sides together. Since it's a rectangle, the other sides are the same measurement as the ones given. Add 3/10, 3/10, 4/5, and 4/5 together. To do this, find a common denominator. The lowest common denominator is 10 so multiply the 4/5 by 2/2 to get the denominator to be 10. Now, add 3/10, 3/10, 8/10, and 8/10. It adds up to 22/10 but if you don't want an improper fraction, simplify it to 2 and 1/5.
