The length of a rectangular room is 6.5 m in the width is 4.23 meters. what is the perimeter of the room? report the answer with appropriate number of significant digits. -21 meters -21.5 meters -21.46 meters -21.460 meters

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
