(1) To determine the 8th term of the sequence, substitute 8 to n of the equation.
a₈ = 3(8) - 5 = 19
Answer is letter B.
(2) It can be observed that the numbers in the sequence is 6 times n (its position) minus 4. Thus, the answer is letter D.
Answer:
22.6°
Step-by-step explanation:
the cosines rule :
cos x = (24²+26²-10²)/2(24)(26)
= (576+676-100)/1248
= 1152/1248
= 0.923
so, x = cos`¹ 0.923 = 22.6°
Scientific notation that's involved with numbers less than one, should always be counted from left to right. Count starting from the decimal until the first number you "jump over". What are you counting exactly?- the number of digits between the decimal and the first 'number' other than zero.
0.0000321 can be also written as 3.21*10^-5 (or 10 with a negative 5 exponent)
Hope this helps.
