Answer:
a. 4P4 = 24
b. 10P2 = 90
c. 5P1 = 5
Step-by-step explanation:
permutation is the act of arranging the members of a set into a sequence or order( in permutation order is important)
Given a permutation nPr
nPr = n!/(n-r)!
Substituting for each of the cases below we have;
a)4P4 = 4!/(4-4)! = 4! = 24
b) 10P2 = 10!/(10-2)! = 10!/8! = 10×9 = 90
c) 5P1 = 5!/(5-1)! = 5!/4! = 5
You are adding:
5a + 2 a+3
------------ + ---------
6a 3a
The LCD here is 6a, so we must mult. numerator and denom. of the 2nd fraction by 2:
5a + 2 2(a+3) 7a + 8
------------ + --------- = -------------- Please note: either write this result as
6a 2(3a) 6a shown, or include parentheses in your
answer: (7a+8) / (6a)
Answer:
Step-by-step explanation:
Complementary angles form a right angle and supplementary angles form a straight angle.
<h3>#7</h3>
<u>Complementary:</u>
<h3>#8</h3>
<u>Supplementary:</u>
- 2x + 6x + 20 = 180
- 8x = 160
- x = 20
I cannot answer that, as I do not have the graph and need more info to answer.
Since we're doing compound interest for four years it will be simpler than daily.
In case you didn't know the formula, here it is: A = P (1 +r/n)^(nt)
now lets substitute.
A = 500 (1 + 0.03)^4
A = 500 (1.03)^4
A = 500 (1.12550881)
A = 562.754405
Since that decimal is too big for cash, let's round it. Notice that the number after 5 is lower than 5. Thus the first two numbers stay the same and the final answer will be..
A = 562.75
Hope this helps :3
