NEED HELP ASAP A family traveling home after a reunion Records the time in hours and the distance they are from home in miles based on the scatter plot the family is miles from home after the first 3.5 hours

300 miles

Step-by-step explanation:

The required answer can be obtiaed by tracing the point where travel time = 3.5 hours directly upward to meet the dotted point. This point is then traced to the y axis which gives the number of miles from home the family has traveled based on the hours they used.

By doing this on the scatter plot Given, the number of miles from home after 3.5 hours is 300 miles.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
