Find an equation of the line in y = mxit b form , that contains the points ( – 1 3 ) and( 4 , – 1 )(20 pts )ind an equation of the circle whose endpoints of a diameter are ( – 1 3 ) and ( 4 , – 1 )(20 pts )Consider the functions defined as followF ( x ) = ( 3* + 1 – 3SXS9 ( x ) = 1 – 2xSXS( Note : 9 ( x ) uses the greatest integer function . For – 4 5 x 5 4 , 9 ( x ) is the greatestinteger less than or equal to – 2x . )Determine each of the following values or say it doesn’t exist( 4 pts each )( – 3 )F ( 2 )9 ( 1.98 )9 ( – 5 )( fog ) ( 100 01 )( gof) ( 3 . 1 )Refer to the graph of the function of in Exercise 16 on page 41 in Section 0.4 of thetextbookWrite down a formula for f ( x ) .

A drone is flying at constant height of$8 meters per sec40 meters above the ground and is traveling at a constant speed of & meters per secondThe drone is exactly overhead at time= 0 . Let @ be the angle between your body andline of sight to the drone15 pts each )What is the slope of your line of sight at time to ? Answer in terms of tWhat is the horizontal distance that the drone has traveled at time to ?Answer in terms of t .What equation do . and to satisfy ? Your answer should involve a trig function , ARefer to the diagram on page 16 in section . 2 if you need
