\f12 of 21 A snowflake gets blown sideways 5 it for every 3 it it falls downward. In one such movement, what is the total distance the snowflake travels and in what direction? O 5.83 ft at 598 from straight downwards. O 5.83 ft at 42 from straight downwards. O 4.00 ft at 42" from straight downwards. O 4.00 ft at 51 from straight downwards\f14 of 21 Given the following matrix equation, which of the following is the correct matrix solution, A? -5 -2 1 A = 2.5 -4 + 3.6 -7 90 Cn 6 15 6 O A= 7 -11 2 -23 20.5 O A = 19.7 -31.9 11.1 59.1 -19.7 16.1 O A = 23 -35.2 13.3 69 -5.5 2.5 O A= 3.4 -4.2 1 6.315 of 21 Kelley and Stuart bought bottled soft drinks for a party at the same store. Kelley spent $31.15 for 5 large bottles and 13 small bottles. Stuart bought 6 large and 10 small bottles of soft drinks for $30.38. What was the cost of a small bottled soft drink? (Hint: The equation for Kelley's purchases is: 5L + 135 = 31.15 First determine the equation for Stuart's purchases, and then solve the system of equations using matrices.) O $1.15 for a small bottled soft drink O $0.95 for a small bottled soft drink O $1.45 for a small bottled soft drink O $1.25 for a small bottled soft drink\f17 of 21 Evaluate the given limit of lim t+ 2 if it exists . 14-27-4 O O limit does not exist O O18 of 21 Evaluate the given limit of lim if it exists. c+1 0 5 O 1 O 2 O limit does not existlime-+1 f(x) = O -2 O -1 O Does not exist 0 220 of 21 What is the average rate of change of , with respect to * over the interval [-1, 2] for the function y = 3x +2?
