Answer:

9

Step-by-step explanation:

This is an equality. R is for 12 since it's 12 in total. Multiply 3 with 12 since every round last 3 minutes. The answer is 36. On the other hand, multiply 2 times 2 for every 2 rounds and it equals 4. Divide 36 by 4 which equals 9.

Describe the graph of y=1/2x-10 -3 comapred to the graph of y= 1/x
saw5 [17]

The parent function is:

$y=\frac{1}{x}

The transformed function is:

$y=\frac{1}{2 x-10}-3

$y=\frac{1}{2(x-5)}-3

$y=\frac{1}{2}\left(\frac{1}{x-5}\right)-3

Comparison of simplified transformed function with the parent function:

  • The function multiplying by a number indicates dilation.
  • The function is being compressed in vertical direction by a factor of 2 if the number lies between 0 and 1.
  • Subtracting a number from x indicates a horizontal shift towards right.
  • That is the parent function is transformed 5 units to right.
  • Subtracting a number from the function indicates a downward shift.
  • That is the parent function is transformed 3 units down.

Hence the graph of y=\frac{1}{2 x-10}-3 is the graph of y=\frac{1}{x} stretched vertically, shifted right by 10 unit and shifted 3 unit down.

The image of the graph is attached below.
