Solve the following equation for r : logg8 x + logg8(-41 + 60r) = 1 Note: Write your answer as a fraction (For example, write 1/2 but not 0.5) T =Remaining Time: 02:44:01 Evaluate the following without using a calculator COS 1 (cos ( 30 )) Note: Write your answer as a fraction, do not write decimal approximations. For example, write 1/2 but not 0.5. If the answer has a # then write Pi or pi or . COS 1 cos 90Remaining Time: 02:43:54 Evaluate the following without using a calculator tan sin 19 Note: Write your answer as a fraction, do not write decimal approximations, for example, write 1/2 but not 0.5. If the answer has a squre root then use the equation editor or use parentheses, for example, for v/3 write (3)^(1/2) do not write (3)^(1/2) or (3) (1/2]. tan sin 1 19Remaining Time: 02:43:48 Evaluate the following without using a calculator sin 2tan 1 -1 ( 34) Note: Write your answer as a fraction, do not write decimal approximations, for example, write 1/2 but not 0.5. If the answer has a squre root then use the equation editor or use parenthesis, for example, for v 3 write (3)*(1/2) do not write (3)
