The sum of the first (n) terms of the sequence is given by the formula (given below) . If this sequence is a geometric progression, find q. If this sequence is an Arithmetic progression, find d
Answer:Example 1:
Find the sum of the first 8 terms of the geometric series if a1=1 and r=2.
S8=1(1−28)1−2=255
Example 2:
Find S10 of the geometric sequence 24,12,6,⋯.
First, find r.
r=r2r1=1224=12
Now, find the sum:
S10=24(1−(12)10)1−12=306964
Example 3:
Evaluate.
∑n=1103(−2)n−1
(You are finding S10 for the series 3−6+12−24+⋯, whose common ratio is −2.)
Sn=a1(1−rn)1−rS10=3[1−(−2)10]1−(−2)=3(1−1024)3=−1023
In order for an infinite geometric series to have a sum, the common ratio r must be between −1 and 1. Then as n increases, rn gets closer and closer to 0. To find the sum of an infinite geometric series having ratios with an absolute value less than one, use the formula, S=a11−r, where a1 is the first term and r is the common ratio.
Example 4:
Find the sum of the infinite geometric sequence
27,18,12,8,⋯.
First find r:
r=a2a1=1827=23
Then find the sum:
S=a11−r
S=271−23=81
Example 5:
Find the sum of the infinite geometric sequence
8,12,18,27,⋯ if it exists.
First find r:
r=a2a1=128=32
Since r=32 is not less than one the series has no sum.
Step-by-step explanation:
What are the exact solutions of x2 − 5x − 7 = 0, where x equals negative b plus or minus the square root of b squared minus 4 times a times c all over 2 times a
Answer:
[tex]x = \frac{5 + \sqrt{53}}{2}[/tex] or [tex]x = \frac{5 - \sqrt{53}}{2}[/tex]
Step-by-step explanation:
Given
[tex]x^2 - 5x - 7 = 0[/tex]
Required
Solve for x using:
[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
First, we need to identify a, b and c
The general form of a quadratic equation is:
[tex]ax^2 + bx + c = 0[/tex]
So, by comparison with [tex]x^2 - 5x - 7 = 0[/tex]
[tex]a = 1[/tex] [tex]b = -5[/tex] [tex]c = -7[/tex]
Substitute these values of a, b and c in
[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
[tex]x = \frac{-(-5) \± \sqrt{(-5)^2 - 4 * 1 * -7}}{2 * 1}[/tex]
[tex]x = \frac{5 \± \sqrt{25 +28}}{2}[/tex]
[tex]x = \frac{5 \± \sqrt{53}}{2}[/tex]
Split the expression to two
[tex]x = \frac{5 + \sqrt{53}}{2}[/tex] or [tex]x = \frac{5 - \sqrt{53}}{2}[/tex]
To solve further in decimal form, we have
[tex]x = \frac{5 + 7.28}{2}[/tex] or [tex]x = \frac{5 - 7.28}{2}[/tex]
[tex]x = \frac{12.28}{2}[/tex] or [tex]x = \frac{-2.28}{2}[/tex]
[tex]x = 6.14[/tex] or [tex]x = -1.14[/tex]
Which of the sets of ordered pairs represents a function? (1 point)
P = {(6, −7), (3, −2), (−9, 2), (−5, −7)}
Q = {(−7, 8), (4, −6), (−3, 1), (1, 5)}
Answer:
Conclusion:
Both sets represent the function.
Step-by-step explanation:
We know that a function relates an input to an output.For example, a certain plant grows 10 cm each year. Thus, the height of the plant is associated with its age using the function
h (age) = age × 10
Thus, if the age of the plant is 2 years, the height is:
h(10) = 2 × 10 = 20 cm
Set P
P = {(6, −7), (3, −2), (−9, 2), (−5, −7)}
The set P represents the function because the function relates an input to an output. In other words, here each input is related to exactly one output.
The x-values are 6, 3, -9, and -5.
Thus, there are no duplicated inputs or x-values.
Therefore, the set P of ordered pairs represents a function.Set Q
Q = {(−7, 8), (4, −6), (−3, 1), (1, 5)}
The set P represents the function because the function relates an input to an output. In other words, here each input is related to exactly one output.
The x-values are -7, 4, -3, and 1.
Thus, there are no duplicated inputs or x-values.
Therefore, the set Q of ordered pairs also represents a function.Conclusion:
Both sets represent the function.

You deposit $200 each month into an account earning 2% interest compounded monthly. How much will you have in the account in 30 years? How much total money will you put into the account? How much total interest will you earn?
Answer:
A. $99,195.055
B. $72,000
C. $27,195.055
Step-by-step explanation:
A. Calculation for How much will you have in the account in 30 years
Using future annuity formula
Future value=[Deposit amount* (1+Interest rate^n-1)/Interest rate]
Let plug in the formula
Where,
Deposit amount=$200
Number of days=30*12=360
Interest rate=0.02/12=0.0017
Let plug in the formula
Future value=[$200*(1+0.0017^360-1)/0.0/17]
Future value=[$200*(1+0.0017^360-1)/0.0/17]
Future value=[$200*(1.0017^360-1)/0.0/17]
Future value=$99,195.055
Therefore the amount you will have in the account in 30 years will be $99,195.055
B. Calculation for How much total money will you put into the account
Using this formula
Total money=Deposit amount*Number of days
Let plug in the formula
Total money=$200*360 days
Total money=$72,000
Therefore the total money you will put into the account is $72,000
C. Calculation for How much total interest will you earn
Total Interest=$99,195.055-$72,000
Total Interest=$27,195.055
Therefore the total Interest you will earn is $27,195.055
Eric bought a ruler for $1.29 and an eraser for $0.39. He paid with $2.00. What is the correct amount of change he should get back?
Answer:
$0.32, so a quarter a nickel and 2 pennies
Step-by-step explanation:
Answer:
$0.32
Step-by-step explanation:
First, add $1.29+$0.39 to get the total amount of the transaction.
$1.29+$0.39 = 1.68
Then, subtract that from the amount paid.
$2.00-$1.68
= $0.32

Write the SLOPE INTERCEPT form of a line that passes through point A at (4,-3) and point B at (2,1)
Answer:
y = -2x + 5
Step-by-step explanation:
A(4, -3) ; B(2, 1)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]= \frac{1-[-3]}{2-4}\\\\= \frac{1+3}{2-4}\\\\= \frac{4}{-2}\\\\= -2[/tex]
m = -2 ; A(4,-3)
[tex]y - y_{1}=m(x-x_{1})\\\\y -[-3] = (-2)(x - 4)\\\\y + 3 = -2*x -4 *(-2)\\\\y + 3 = -2x + 8\\\\ y = -2x + 8 - 3 \\\\ y = -2x + 5[/tex]

A line has a slope of 3, is increasing, and passes through the point (2,7). What is its y-intercept?
The y-intercept of the line is 1
Using the slope - intercept relation :
y = bx + cc = Intercept; b = slope point (2,7)Substituting the values into the relation :
7 = 3(2) + c
7 = 6 + c
c = 7 - 6
c = 1
Therefore, the y-intercept of the line is 1.
