Answer:
127 feet below sea level
Step-by-step explanation:
You put the -2 over a 1, and a 1 under the -3. On the y axis, go to -2 and put a dot. Go down three, and right one. To go up, you go up three and left one.
Answer:
529.41
Step-by-step explanation:
From the above question, we are to find the Principal
The formula to find the Principal (Initial amount invested) is =
P = A / (1 + rt)
Where
A = Amount paid after t years. = 720
r = rate of interest = 6% = 0.06
t = time in years = 6
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Solving our equation:
P = 720 / ( 1 + (0.06 × 6)) = 529.41176470588
Approximately
P = 529.41
Therefore, Kaitlyn's brother borrowed 529.41 for school
Answer:
140
Step-by-step explanation:
The arithmetic series is 5, 7, 9, 11, ........., 23.
First u have to determine the no. of terms that can be done by using
Tₙ = [a + (n - 1)d]
Tₙ-------nth term
a---------first term
n---------no.of terms in the series
d---------common difference
here a = 5,d = 2.
let it contain n terms Tₙ= [a + (n-1)d]
Substitute Tₙ, a, and d in the equation
23 = 5 + (n - 1)2
Subtract 5 from each side.
18 = (n-1)2
Divide each side by 2
(n - 1) = 9
Add 1 to each side
n = 9 + 1 = 10
The sum of the arithmetic sequence formula: Sₙ= (n/2)[2a+(n-1)d]
Substitute Sₙ, a, n and d in the equation
Sₙ= (10/2)[2(5) + (10-1)2]
Sₙ= (5)[10 + (9)2]
Sₙ= 5[10 + 18]
Sₙ= 5[28] = 140
Therefore the sum of the arithmetic sequence is 140.
