Step-by-step explanation:
C4H6O3 + H2O => 2C2H4O2
C2H4 + 3O2 => 2CO2 + 2H2O
C4H10O + 6O2 => 4CO2 + 5H2O
The correct answer is: [A]: " -5 ≤ y <span>≤ 5 " .
_________________________________________________
The "range" refers to the the values of a function that encompass the "y-axis" of the [graphed] function.
By looking at the graph provided in the image attached, we see that for "y" values (when "y" is "positive", or "greater than "0"; the highest value for "y" is "5"; yet "y" never "exceeds "5". We see that for "y" values (when y is "negative", or "less than "0", the lowest values for "y" is "-5"; yet "y" never goes "lower than "-5".
However, "y" values are aways within, and encompassing, all "y" values between and including: "y = -5" and "y = 5" .
As such, Answer choice: </span>[A]: " -5 ≤ y ≤ 5 " ; is correct.

Answer:
I Already Said It's 5000 Bro
4:42 p.m
You start with 9:17 and you subtract 4 hours. That gives you 5:17. Now you have to subtract the remaining 35 minutes. To make things easy we can make 5:17, five o-clock. We can do this by subtracting 17 then you'll get five o-clock. Now you have another 28 minutes to subtract. 5:00 - 28 = 4:42. Then you add the p.m.
The answer is C. PQS ~ QRS
Since R of QRS is a right angle, and Q of PQS is also a right angle, they are similar.
Since S remains the same angle for both triangles and since Q and R are the same (90°), then the angles of P and R of PQS must be the same as well.
Thus, PQS ~ QRS
