Answer: The given sums in sigma notation are
(a)
(b)
(c)
(d)
Step-by-step explanation: We are given to express the following sums using sigma notation.
(a) 9 plus 10 plus 11 plus 12 plus 13.
Here, sum is
In sigma notation, the given sum can be written as follows :
(b) 2 plus 4 plus 6 plus 8 plus 10 plus 12.
Here, sum is
In sigma notation, the given sum can be written as follows :
(c) 1 Superscript 6 Baseline plus 2 Superscript 6 Baseline plus 3 Superscript 6 Baseline plus 4 Superscript 6.
Here, sum is
In sigma notation, the given sum can be written as follows :
(d) one fifth plus one sixth plus one seventh plus one eighth.
Here, sum is
In sigma notation, the given sum can be written as follows :
Thus, the given sums in sigma notation are
(a)
(b)
(c)
(d)
Answer:
1. C 2. A 3. B
Step-by-step explanation:
Step 1: 12x - 6 = 10 divided by 2 is 6x - 3 = 5
Step 2: When you add three to the left side of the equation the negative 3and positive 3 cancel out and when you add three to the right side of the equation 5 + 3 = 8
Step 3: multiplying both sides by 1/6. 1/6 is the reciprocal of 6 so they cancel out. 1/6 times 8 is 8/6 which condenses to 4/3 in simple terms.
The missing angle is 49 :)
150 is the amount of interest earned for one year because the formula of PRT is, in this case 5000 times 0.03 times one which gets you the answer of 150.
