Answer:
|x - 34| = 4
Step-by-step explanation:
Minimum height of handrail stated by the safety regulation = 30 inches
Maximum height of handrail stated by the safety regulation = 38 inches
Mean of these heights =
If a handrail having height = x
Then the difference between height of the handrail and mean height = (x - 34)
This difference should be equal to 4.
Algebraic representation for a height "x inches" will be
|x - 34| = 4

Answer:
45,000 people
Step-by-step explanation:
Let
P -----> the number of people, that are left in the stadium
M ----> the time in minutes
we have
This is a linear equation in slope intercept form
where
The slope is
----> is negative because is a decreasing function
The P-intercept is
Remember that the P-intercept is the value of P when the value of M is equal to zero
That means
For M=0 min
P=45,000 people (number of people that were present when the game ended but before people started to leave)
Answer:

Answer:
The equation of the parabolic function is :
Step-by-step explanation:
The standard equation of a parabola is given by:
where represents the vertex of the parabola.
From the graph shown in figure we can find the vertex of the parabola which is the minimum point of parabola and lies st point
So, we can say:
Plugging in the values of vertex in standard equation of parabola,
Simplifying the equation:
We can find value of by plugging in a point from the graph.
Using point (0,-2) which lies on graph.
Plugging in the given point.
Adding 3 to both sides.
∴
Plugging in , the equation of parabola can be written as:
