Answer:
Graph of Option D represents
Step-by-step explanation:
we are given our function as
squaring on both sides we get
It represent a parabola opening towards the positive side of x axis. Hence it gives us some preliminary idea about the graph of the function we are given .
However our original function is 
Domain of
is all positive values of x
And square root of positive values will always result in positive values. Hence y can not be negative as the range is All positive values of y
Hence we erase the graph of
below x axis to obtain the graph of

Answer:
y = 9/b
Step-by-step explanation:
by = 9 solved for b yields y = 9/b.
First add the ratio 1:3:5 together to give you the total number:
1 + 3 + 5 + = 9
Therefore you divide 72 by 9 to give you one part
72 divide 9 = 8
Now you times each part of the ratio by 8:
1 x 8 = 8
3 x 8 = 24
5 x 8 = 40
Therefore the answer would be written like this:
8:24:40
Hope this helps
7.75 ➗ 125 = 0.062
Simplify ➡ 31 / 4
31 over 4 ➗ 125
Then, divide ➡31 over 1 by 125
and it should leave you with the answer 0.062
