Aswimmer swam the 50-meter freestyle in a time of 21 seconds. what was his speed to the nearest tenth of a meter per second?
a. o.4
b. 2.4
c. 23.8
d. 29.0

Speed of swimmer is 2.4 m/s (Approx.)

Given that;

Total distance cover = 50 meter

Time taken to cover distance = 21 second

Find:

Speed of swimmer

Computation:

Speed =  Distance / Time

Speed of swimmer = Total distance cover / Time taken to cover distance

Speed of swimmer = 50 / 21

Speed of swimmer = 2.38 m/s

Speed of swimmer = 2.4 m/s (Approx.)

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
