Every two years, a manufacturer's total yearly sales decline 20%. She sells 400 total units in her first year. Rounded to the nearest unit, how many total units will she sell her ninth year?
146.54 units are the total units will she sell her ninth year.
Here, we have,
periodic exponential decay is:
[tex]A = I(1-r)^{t/p}[/tex]
where,
A = amount
I = initial amount
r = rate
t = time
p = period
we know, the first year she sold 400 units,
thus year 0, 400 units, t = 0, A = 400.
so, we get,
periodic exponential decay is:
[tex]A = I(1-r)^{t/p}[/tex]
=> 400 = I × 1
=> 400 = I
therefore then, when, rate = 20 %
we get,
periodic exponential decay is:
[tex]A = I(1-r)^{t/p}[/tex]
[tex]= > A = 400(1-0.2)^{t/2}[/tex]
now, how many units will it had decreased by the 9th year? t = 9
so, we get,
[tex]= > A = 400(1-0.2)^{9/2}[/tex]
=> A = 146.54

Step-by-step explanation:
Suppose you have two credit cards. The first has a balance of $415 and a credit limit of $1,000. The second has a balance of $215 and a credit limit of $750. What is your overall credit utilization?
Compute for the total balance:
total balance = $415 + $215 = $630
Then we compute for the total credit limit:
total credit limit = $1,000 + $750 = $1,750
The credit utilization would simply be the percentage ratio of total balance over total credit limit. That is:
credit utilization = ($630 / $1,750) * 100%
credit utilization = 36%

steps to solve this equation 25 1/7- 12 5/7=
To solve the equation 25 1/7 - 12 5/7, subtract the whole numbers and fractions separately, and combine them back into a mixed number to get the solution, which is 12 3/7
To solve the equation 25 1/7 - 12 5/7, follow these steps:
First, break the mixed numbers into whole numbers and fractions: (25 + 1/7) - (12 + 5/7).Next, subtract the whole numbers: 25 - 12 = 13.Subtract the fractions: 1/7 - 5/7. Since the denominators are the same, simply subtract the numerators: 1 - 5 = -4. This gives us -4/7, but since we can't have a negative fraction in this context, we'll take 1 away from the whole number 13 and convert it to 7/7, to make the equation easier to solve.Now you have 12 (since we took 1 from 13) and 7/7 - 4/7, which equals 3/7.Add the whole number and the fraction: 12 + 3/7 = 12 3/7.The solution to the equation is 12 3/7
Find a solution x = x(t) of the equation x′ + 2x = t2 + 4t + 7 in the form of a quadratic function of t, that is, of the form x(t) = at2 + bt + c, where a, b, and c are to be determined.
To find a, b, c for the solution:
Let's start by writing down the expression for the function x(t) and its derivative:
We have:
x(t) = at² + bt + c
and
x'(t) = 2at + b
Using x' and x into the differential equation x′ + 2x = t² + 4t + 7 gives us:
2at + b + 2*(at² + bt + c) = t² + 4t + 7
Expanding this gives:
2at² + 2bt + b + 4at + 2c = t² + 4t + 7
By equating the coefficients of equivalent powers of t on both sides, we get three equations:
For t² :
2a = 1
So, a = 1/2
For t:
2b + 4a = 4
Substitute a = 1/2 into the equation gives b = 1 - 2 = -1
For the constant term:
b + 2c = 7
Substituting b = -1 gives c = 4.
So the solution is a = 1/2, b = -1, c = 4.
So the specific solution of this differential equation is given by x(t) = (1/2)t² - t + 4.

D is the midpoint of CE.E has coordinates (-3,-2), and D has coordinates (2 1/2, 1). Find the coordinate of C.
The coordinate of point C on line CE will be (8, 4).
What is Coordinates?
A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
D is the midpoint of CE.
E has coordinates (-3,-2), and D has coordinates (2 1/2, 1).
Now, By the definition of midpoint;
Let the coordinate of point C = (x, y)
Then,
((x + (-3))/2 , (y + (-2))/2) = (2 1/2, 1)
By comparison we get;
x + (-3) / 2= 2 1/2
x - 3 = 2 (5/2)
x - 3 = 5
x = 3 + 5
x = 8
And, (y + (-2))/2 = 1
y - 2 = 2
y = 2 + 2
y = 4
Thus, The coordinate of point C = (x, y) = (8, 4)
So, The coordinate of point C on line CE will be (8, 4).

Alan sells custom made kites online. He makes a flat profit of $20 per kite, but he pays $20 per day for his website. Write an inequality that gives the number of kites Alan needs to sell to make at least $900 per week?
Profit on each kite that Allan sells= $ 20 per kite
Amount paid by Allan for his Website = $ 20 per day
Let number of kites sold by Allan per day = x
In 7 days , number of kites sold = 7 x
Amount paid by Allan for his Website in 7 seven days = 20 × 7=$140
We have to make an equality describing number of kites Alan needs to sell to make at least $900 per week.
The Inequality is
→20×7 x -140 ≥ 900
→ 140 x ≥ 900 + 140
→ 140 x ≥1040
→ 7 x ≥ 52 (Minimum number of kites that allan should sell in a week)
Dividing both sides by 140,we get
→ x ≥ [tex]\frac{1040}{140}=7.43[/tex]= 8 kites in a day(approx)
Start at 5. Create a pattern that multiplies each number by 3 and subtracts 2. Stop when you have 5 numbers.
Answer: The required pattern is 13, 37, 109, 325, 973
Step-by-step explanation:
Since, each number in the sequence follows the following rule,
2 less than the 3 times of the previous number.
If we start from 5,
Then first number of the sequence = 3×5 - 2 = 15 - 2 = 13
Second number = 3× 13 - 2 = 39 - 2 = 37
Third number = 3× 37 - 2 = 111 - 2 = 109
Fourth number = 3×109 - 2 = 327 - 2 = 325
Fifth number = 3× 325 - 2 = 975 - 2 = 973
Hence, The required sequence is,
13, 37, 109, 325, 973
