A dolphin jumps from the water with an initial velocity of 44 feet per second at an elevation angle of 60 degrees Which parametric equations model the dolphin’s path through the air?
Answer
A
x times t is equal to 44 sine open paren 60 degrees close paren t and y times t is equal to negative 16 t squared plus 44 cosine open paren 60 degrees close paren t
B
x times t is equal to 44 cosine open paren 60 degrees close paren t and y times t is equal to negative 16 t squared plus 44 sine open paren 60 degrees close paren t
C
x times t is equal to sine open paren 60 degrees close paren plus 44 and y times t is equal to negative 16 t squared plus cosine of open paren 60 degrees close paren plus 44
D
x times t is equal to cosine open paren 60 degrees close paren plus 44 and y times t is equal to negative 16 t squared plus sine open paren 60 degrees close paren plus 44
