21. compare the numbers 5/9 and 0.5. use the symbols < , > , or =.
a) 5/9=0.5
b) 5/9> 0.5
c) 5/9< 0.5

B)

Step-by-step explanation:

We are asked to compare the numbers 5/9 and 0.5.

Let us convert 0.5 as a fraction. We will divide and multiply 0.5 by 10 as:

Now, we will make a common denominator for both numbers as:

Therefore, and option B is the correct choice.

12.5 feet

step-by-step explanation:

(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.
