Semi --> twice
semimonthly --> occuring twice a month
Thus:
You are paid twice a month
12 months in a year
12 x 2 = 24 paychecks an year
$540
Step-by-step explanation:
$150 × 4 = $600
$600 ÷ 10 = $60
$600 - $60 = $540
Answer:
In December, Zalma will have $480.
Step-by-step explanation:
The time from March to October is 7 months. In those 7 months, she gains $280. So every month, her investment gains $40.
The time from March to December is 9 months. She will gain $360 during that time. We add her initial $120 with the $360, and Zalma will have $480.
It's not confirmed, but it's what I got. :D
Answer:
see explanation
Step-by-step explanation:
(a)
Given
2k - 6k² + 4k³ ← factor out 2k from each term
= 2k(1 - 3k + 2k²)
To factor the quadratic
Consider the factors of the product of the constant term ( 1) and the coefficient of the k² term (+ 2) which sum to give the coefficient of the k- term (- 3)
The factors are - 1 and - 2
Use these factors to split the k- term
1 - k - 2k + 2k² ( factor the first/second and third/fourth terms )
1(1 - k) - 2k(1 - k) ← factor out (1 - k) from each term
= (1 - k)(1 - 2k)
1 - 3k + 2k² = (1 - k)(1 - 2k) and
2k - 6k² + 4k³ = 2k(1 - k)(1 - 2k)
(b)
Given
2ax - 4ay + 3bx - 6by ( factor the first/second and third/fourth terms )
= 2a(x - 2y) + 3b(x - 2y) ← factor out (x - 2y) from each term
= (x - 2y)(2a + 3b)
