Answer:
all of these have 4 significant figures
Step-by-step explanation:
Answer:
12,200 ft²
Step-by-step explanation:
The area of the lawn = the area of the trapezium - the area of the square
Note that area of a trapezium is h*(a+b)*(1/2), where h is the perpendicular height, and a and b are the top and bottom.
Note that the area of a square is l*w, where l is length and w is width.
Therefore, the area of the lawn = [h*(a+b)*(1/2)] + [l*w]
= [80*(100+140)*(1/2)]+[50*52]
= 9600+2600
=12200
at first we write each one as a sequence
and find its equation
the first table
-19, -11, -3, 5
8x-19
the third table
15,12,9,6
-3x+15
the second table
-1. 5,1.5,3,4.5
+3 +1.5 +1.5
so the third table is the nonlinear function
The answer for the question is 9 is greater than or equal to -1
