Answer:
A(n)=130+13(n-1) ; 86
Step-by-step explanation:
Here is the sequence
130,143,156,169.......
the first term denoted by a is 130 and the common difference denoted by d is second term minus first term
143 - 130 = 13
Hence a=130 and d = 13
Now we have to evaluate to 13th term.
The formula for nth term of any Arithmetic Sequence is
A(n) = a+(n-1)d
Hence substituting the values of a ,and d get
A(n)=130+13(n-1)
To find the 13th term , put n = 13
A(13)=130+13*(13-1)
= 130+13*12
= 130+156
A(13) = 286
Answer:
78 trees
Step-by-step explanation:
No. of trees planted = Area of square
No. of trees planted = 6084
Row = side of square
Side = √(Area)
Side = √(6084)
Side = 78 trees
Answer:
y- intercept = 1
Step-by-step explanation:
The y- intercept is the point on the y- axis where the graph crosses.
This occurs when the x- coordinate is 0
From the table the point (0, 1 ) is where the graph crosses the y- axis
Then y- intercept = 1
