Show that the set is infinite by placing it in a one-to-one corespondence with subset. proper subset of itself. give the general term of the original set, and show its pairing with its proper {47,52,57,62,} the general term of the set is (type the expression using n.) given the first term of the proper subset, type the next 3 terms and the general term. assume that the numbers will continue to differ by 5 {47,52,57, 5n+ 42 (52.. (type the general term using n.)

hi

step-by-step explanation:

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
