Answer:
The second difference, let suppose denoted by d₂, can be obtained by taking the difference between consecutive terms of the first difference of y-values, such as:
Step-by-step explanation:
Given the table
x y
0 3
1 4
2 7
3 12
The (first) difference, let suppose denoted by d, of y values can be obtained by taking the difference between consecutive terms.
The second difference, let suppose denoted by d₂, can be obtained by taking the difference between consecutive terms of the first difference of y-values, such as:
Answer:
33x+55y
Step-by-step explanation:
You multiply 11 by everything in the parentheses
There are 111 faculty members at the college and 629 students at the college.
Step-by-step explanation:
Given,
The student to faculty ratio = 17:3
Total number of 740.
Let,
x be the original number.
Number of students = 17x
Number of faculty = 3x
Number of students + Number of faculty = 740

Dividing both sides by 20

Number of students = 17x = 17*37 = 629
Number of faculty = 3x = 3*37 = 111
There are 111 faculty members at the college and 629 students at the college.

Step-by-step explanation:
the sum of angles in a triangle is 180 degrees
18 + 72 + X = 180
90 + X = 180
X = 180 -90
X = 90
