total: 13.39
13.39 rounded to 13.40 is the sum of the length of string after 10 throws.
Based on the table: I generated the formula:
f(x) = 3 </span></span></span></span>×<span><span><span><span> 0.80</span></span></span></span>ˣ
where the exponent x represents the number of throws.
1. 21j-26+4j=21+6-2j
2. 25j-26=27-2j
3. 27j=53
4. j=53/27
hope this helps!!
Put the numbers given accordingly in the equation
bracket means multiply
2(-2)-5(5)-3(-2)
=-4-25+6
=-23
a. -23
