Ithink its b? without multiplying, determine the sign of the product (356,864)(−194,758). the sign of the product is positive because a positive multiplied by a negative is a positive. the sign of the product is negative because a positive multiplied by a negative is a negative. the sign of the product is negative because the second number is negative. the sign of the product is positive because the first number is positive.

Hello,

The correct answer is B) The sign of the product is negative because a positive multiplied by a negative is a negative.

Hope this helps (:

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

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
