Find the amount (future value) of the ordinary annuity. (Round your answer to the nearest cent.)
$300/week for 9 1/2
years at 5.5%/year compounded weekly
Answers
Answer: $227,226.51
Step-by-step explanation:
First, we need to convert the period to weeks.
9 1/2 years = 9.5 years
1 year = 52 weeks
9.5 years = 494 weeks
Next, we can use the formula for the future value of an annuity:
FV = (PMT x (((1 + r/n)^(n*t)) - 1)) / (r/n)
where:
PMT = payment amount per period
r = annual interest rate
n = number of compounding periods per year
t = number of years
Plugging in the given values:
PMT = $300
r = 0.055 (5.5% expressed as a decimal)
n = 52 (compounded weekly)
t = 9.5 years = 494 weeks
FV = ($300 x (((1 + 0.055/52)^(52*494)) - 1)) / (0.055/52)
FV = $227,226.51
Therefore, the future value of the annuity is approximately $227,226.51.

is 5. Find the number.
Answers
2x + 8 = 11
2x = 3
x= 2/3
According to the question,
The equation will be:
\((2x + 8) - 6 = 5\)By solving the bracket, we get
→ \(2x + 8 - 6 = 5\)
→ \(2x +2 = 5\)
By subtracting "2" from both sides, we get
→ \(2x+2-2= 5-2\)
→ \(2x = 3\)
\(x = \frac{3}{2}\)

What is shape kite in geometry?In Euclidean geometry, a kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other.
Given that, m∠N=53°, ∠T=67° and m∠F=(1/2 x-8)°
In kite the two angles are equal where the unequal sides meet.
So, m∠W=m∠F=(1/2 x-8)°
Now, m∠N+m∠T+m∠W+m∠F=360°

In a direct variation, y=9 when x=3. Write a direct variation equation that shows the relationship between x and y.
Answers
In a direct variation, y=9 when x=3. A direct variation equation that shows the relationship between x and y is y=3x
What do you mean by direct variation?
Direct variation is a type of proportionality when one quantity changes right away in reaction to a change in another variable. This implies that if one number rises, the other will follow suit in a comparable manner. Similar to the last illustration, if one quantity decreases, the other quantity also decreases. Direct variation will have a linear relationship with the graph, resulting in a straight line.
Given,
In a direct variation, y=9 when x=3.
Formulate an equation based on the conditions stated: y=kx
We put the value of the y and x in this equation
9=k*3
Subtract the coefficient of the variable from both sides of the equation
k= 3
We can write the equation of the function by putting the value of k: y=3x

B.
(328 x 128) x k = 328 x (82 x 128)
K=
Answers
Answer:
A. \(n=100\)
B. \(k=0\)
Step-by-step explanation:
A. The equation "110% n = 11" can be solved as follows:
110% n = 11
To solve for n, we need to get rid of the percentage sign (%). We can do this by dividing both sides of the equation by 110%, or 0.110 (since 110% is equivalent to 1.1 in decimal form).
(110% n) / 110% = 11 / 110%
n = 11 / 0.110
n = 100
So, the solution for n in the equation "110% n = 11" is n = 100.
B. The given equation is:
(328 x 128) x k = 328 x (82 x 128) x k
To solve for k, we can simplify the equation using the properties of multiplication.
Step 1: Perform the multiplications inside the parentheses:
41984 x k = 328 x 10576 x k
Step 2: Rearrange the equation by applying the associative property of multiplication:
41984 x k = 328 x (10576 x k)
Step 3: Divide both sides of the equation by 328:
(41984 x k) / 328 = 10576 x k
Step 4: Cancel out the common factor of k on the left-hand side:
(41984 / 328) x k = 10576 x k
Step 5: Simplify the left-hand side:
128 x k = 10576 x k
Step 6: Subtract 10576 x k from both sides of the equation to isolate k:
128 x k - 10576 x k = 0
Step 7: Factor out k on the left-hand side:
k x (128 - 10576) = 0
Step 8: Simplify further:
k x (-10448) = 0
Step 9: Divide both sides of the equation by (-10448):
k = 0
So, the solution for k in the equation "(328 x 128) x k = 328 x (82 x 128) x k" is k = 0.
Suppose a point has polar coordinates (6,5pi/6)with the angle measured in radians.Find two additional polar representations of the point.Write each coordinate in simplest form with the angle in (-2pi, 2pi).
Answers
SOLUTION
To find the additional polar representation of a giving point we use the following
1. By adding or subtracting a multiple of 2π to θ
2. By using a negative radius r, and adding an odd multiple to π
Giving the polar coordinates
\((6,\frac{5\pi}{6})\)The additional coordination will be by adding 2π to θ
\(\begin{gathered} (6,\frac{5\pi}{6}+2\pi) \\ \\ (6,\frac{17\pi}{6}) \end{gathered}\)Hence one addition coordinate is (6,17π/6)
To find additional polar coordinates,
We subtract 2π from θ
\(\begin{gathered} (6,\frac{5\pi}{6}) \\ \text{Then} \\ (6,\frac{5\pi}{6}-2\pi) \\ \\ (6,\frac{5\pi-12\pi}{6})=(6,-\frac{7\pi}{6}) \end{gathered}\)Hence, another additional coordinate is (6,-7π/6 )
Therefore, the two additional polar coordinates are (6,17π/6) and (6,-7π/6 )

Answers
Answer:
Step-by-step explanation:
Red apples : green apples = 13 : 7
Number of red apples = 13x
Number of green apples = 7x
Number of red apples sold = 60% of 13x
Remaining red apples = 40% of 13x
= 0.4 * 13x
= 5.2x
Number of green apples sold = 55
Remaining green apples = 7x - 55
After selling, ratio
Red apples : green apple = 13 : 12
5.2x : 7x -55 = 13:12
\(\frac{5.2x}{7x-55} = \frac{13}{12}\)
Cross multiply,
12*5.2x =13 * (7x -55) {use distributive rule}
62.4 x = 91x - 715 {add 715 to both sides}
62.4x + 715 = 91x {subtract 62.4 from both sides}
715 = 91x - 62.4x
715 = 28.6x
28.6x = 715
x = 715/28.6
x = 25
Number of red apples = 13x = 13*25 = 325
Number of green apples = 7x = 7 * 25 = 175
b) Number of red apples left = 5.2x = 5.2 *25 = 130
Number of red apples bought now = \(\frac{3}{10}*130\)
= 3*13 = 39
Number of red apples she had at the end = 39 + 130 = 169

The angle formed by the two hands have a measure less than 1/4 turn
How to relate the measure of the angle to 1/4 turn?From the question, we have the following parameters that can be used in our computation:
A clock with the hour hand at 12 and the minute hand at 2
The turn represented by the above is represened as
Turn = (2 * 30)/360
When simplified, we have
Turn = 1/6
Next, we have
Angle at the turn = 1/4
1/6 is less than 1/4

A TV cable company has 9600 subscribers who are each paying $36 per month. It can get 160 more subscribers for each $0.50 decrease in the monthly fee. What rate will yield maximum revenue, and what will this revenue be?
Answers
The function has the maximum revenue of $348,480 with the increasing rate of $33.
Explain about the maxima of function:The highest and smallest values of a function, respectively, can either be found inside a specific range or distributed throughout the entire domain. They are also sometimes referred to collectively as the function's extrema. The plural forms of a function's maximum and minimum are called maxima and minima, accordingly.
Given data:
We are aware that monthly subscription fees are $36.The corporation can increase its subscription count for a $0.50 drop.We also know that the business has 9600 subscribers and has the capacity to add 160 more.The overall revenue is thus:
y = (36 - 0.50x)(9600 + 160x)
Differentiate with respect to x.
y ' = (-0.50)(9600 + 160x) + 160(36 - 0.50x)
y' = -4800 - 80x + 5760 - 80x
y' = 960 - 160x
To find x, put y' = 0
960 - 160x = 0
x = 960/160 = 6 (critical point)
Function is decreasing in interval - [6, +∞)
Increasing Function in interval - (-∞, 6]
Thus, the function has the maximum value at x = 6.
maximum revenue f(6):
f(6) = (36 - 0.50x)(9600 + 160x)
f(6) = (36 - 0.50(6))(9600 + 160(6))
f(6) = $348,480
Rate : 36 - 0.50(6) = $33
The function has the maximum revenue of $348,480 with the increasing rate of $33.
