80 What happens to the value of the expression 80/h as h increases from a small positive number to a large positive number? Choose 1 answer It increases. It decreases. ​

Respuesta :

Answer:  Decreases

Reason

Let's make a table of values. A spreadsheet or graphing calculator that supports tables is recommended.

[tex]\begin{array}{|c|c|} \cline{1-2}h & 80/h\\\cline{1-2}1 & 80\\\cline{1-2}2 & 40\\\cline{1-2}4 & 20\\\cline{1-2}8 & 10\\\cline{1-2}16 & 5\\\cline{1-2}20 & 4\\\cline{1-2}40 & 2\\\cline{1-2}80 & 1\\\cline{1-2}\end{array}[/tex]

As h gets bigger, the expression 80/h gets smaller, and vice versa. The two expressions go in opposite directions.

This will mean as h gets smaller, then 80/h gets bigger, and vice versa.

Notes:

  • We cannot have h = 0 in the denominator. Dividing by zero is undefined.
  • 80/h is the same as [tex]\frac{80}{h}[/tex] and also the same as 80 ÷ h
