For the expression 5x?y3 + xy2 + 8 to be a trinomial with a degree of 5, the missing exponent on the x-term must be ___ (fill in the blank)

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

i am thinking c. sorry if im wrong .

step-by-step explanation:

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

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
