Answer: choice A) 7017
==========================================================
Work Shown:
The first term is a_1 = 24 and we go up by 7 each time.
The common difference is d = 7
The nth term formula we'll use is
a_n = a_1 + (n-1)*d
a_n = 24 + (n-1)*7
----------
The 1000th term corresponds to n = 1000
Replace every n with 1000
Then use the order of operations (PEMDAS) to simplify
a_n = 24 + (n-1)*7
a_1000 = 24 + (1000-1)*7
a_1000 = 24 + (999)*7
a_1000 = 24 + 6993
a_1000 = 7017
Answer:
C
Step-by-step explanation:
Given
x² - 3x - 12 = 0 ( add 12 to both sides )
x² - 3x = 12
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- )x + = 12 +
(x - )² = ( take the square root of both sides )
x - = ± = ± ( add to both sides )
x = ±
Then
x = + ≈ 5.27 ( to the nearest hundredth )
x = - ≈ - 2.27 ( to the nearest hundredth )
