I don’t think you can solve by using quadratic equation
It is very important to look at all the details that are already given in the question. Only then the problem should be started for solving.
Initial population of Memphis = 350000
population of Memphis after 1 year = 406000
Then
Increase in population of Memphis in a year = 406000 - 350000
= 56000
Then
Percentage increase in the
population of Memphis in a year = (56000/350000) * 100
= (56 * 10)/35
= 560/35
= 16 percent
So there is a 16% increase in the population of Memphis in a year.
Answer:
(2,0) - x -intercept
(0, 1.5) - y-intercept
Step-by-step explanation:
The slope of the points can be found by writing a ratio of vertical change to horizontal change. It can be found in the table by subtracting y values from each other and subtracting x values from each other. The y values decrease by 3 each time or -6 - -3 = -6 + 3 = -3.
The x values increase by 4.
So the rate of change is -3/4.
This means if you go backwards on the table the previous point would be (2, 0). This is the x-intercept.
To find the y-intercept, you must go further back. Going back 2 more units would make the table appear as:
x y
-2 3
0 ???
2 0
6 -3
10 -6
14 -9
Since the y values decrease by 3 each time and we went back half the usual amount, then the value would be 1.5.
X= 5+ √5/4, x=5-√5/4 USE SYMBOLAB!!
Total number of students = 18 + 7 = 25
Average height of the 25 students = 105 - 5 = 100 cm
Sum of height of all students = 100 x 25 = 2500cm
Answer: 2500cm
