Answer with Step-by-step explanation:
We are given that point B lies on the segment AC.
Length of AC= a cm
We have to find the the distance between the midpoint of segment AB and BC.
When B lies on the segment AC.
Let mid point of segment AB and BC are E and F.
E is the midpoint of segment AB.
Therefore, 





Distance between E and F is given by


Hence, the distance between the midpoints of segment AB and BC is given by

The 4 is the constant term.
Answer:
Step-by-step explanation:
In each case, the axis of symmetry is the vertical line through the vertex.
<u>For f(x)</u>
The equation is in vertex form:
f = a(x -h)² +k . . . . has vertex (h, k)
The x-coordinate of the vertex can be read from the equation: 4. The vertical line with that x-coordinate is ...
x = 4
__
<u>For h(x)</u>
The vertex is the point where the graph reaches a maximum, (-2, 2). The vertical line with that x-coordinate is ...
x = -2
Answer:
The correct answer is B
Step-by-step explanation:
In this problem, Solution A isnt possible because if he washes 10 cars he earns $80 so that should be in the domain
Solution B is the correct one because it collects all the possible numbers of the equation, from 0 car washed=$0 to 10 car washed=$80(1 by 1)
The problem with solution c is the same as solution A
Finally, Solution D has an small problem, and that is that if he washes 10 cars the amount he gains is $80 so x cant be <$80, it should have been ≤$80
