Use the graph to solve. A table tennis ball that has been hit is about 13.52 times as fast as the speed for the swimming. What is the speed for the table tennis ball? [I don't know if the graph image I uploaded is there or not if it isn't just comment that thanks]

The average human heart beats 1.15 \cdot 10^51.15⋅10 5 1, point, 15, dot, 10, start superscript, 5, end superscript times per day. there are 3.65 \cdot 10^23.65⋅10 2 3, point, 65, dot, 10, start superscript, 2, end superscript days in one year.how many times does the heart beat in one year? write your answer in scientific notation, and round to one decimal place.

What is the missing step in this proof ?
