Answer:
13%
Step-by-step explanation:
Given 1817 and 1580
Increase = 1580 - 1817
= 237
Percentage increase = increase/1817 x 100%
That’s 237/1817 x 100%
0.130 x 100%
13.0
13%
Answer:
Pat a) The unit rate of graph at left is
Part b) The unit rate of graph at right is
see the attached figure
Step-by-step explanation:
we know that
The unit rate of a linear equation is the same that the slope of the linear equation
step 1
Find the slope of the graph at left
This graph represent a proportional relationship (because the line passes through the origin)
The slope is equal to the constant of proportionality k
we have the point (1,25)
substitute the values in the formula
step 2
Find the slope of the graph at right
we have the points (2,80) and (3,120)
This graph represent a proportional relationship (because the line passes through the origin)
The slope is equal to the constant of proportionality k
Is necessary only one point to determine the constant of proportionality
take the point (2,80)
substitute the values
<u>Verify</u>
The formula to calculate the slope between two points is equal to
we have the points (2,80) and (3,120)
substitute the values
Answer:
The axis of symmetry is
Step-by-step explanation:
we know that
In a vertical parabola, the axis of symmetry is equal to the x-coordinate of the vertex
In this problem we have a vertical parabola open upward
The x-coordinate of the vertex is equal to the midpoint between the zeros of the parabola
so
therefore
The axis of symmetry is
