The population of a city grows exponentially at rate of 8% per year.Find the number of years it takes for the population to be doubled Give your answer correct to the nearest whole number
Answers
Answer:
It will take 9 years for the population to double
Step-by-step explanation:
Exponential Growth
The natural growth of some magnitudes can be modeled by the equation:
\(P=P_o(1+r)^t\)
Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.
The population of a city grows at a rate of r=8% = 0.08 per year. We are required to find when (t) the population will double, or P=2Po.
Substituting in the equation:
\(2P_o=P_o(1+0.08)^t\)
Simplifying:
\(2=(1.08)^t\)
Taking logarithms:
\(\log 2=\log (1.08)^t\)
Applying the exponent property of logs:
\(\log 2=t\log (1.08)\)
Solving for t:
\(\displaystyle t=\frac{\log 2}{\log (1.08)}\)
Calculating:
\(t\approx 9\)

Answers
For the given arithmetic sequence we have:
A) \(A_n = 20 + (n - 1)*3\)B) 22 rows.C) \(\sum_{n = 1\ to\ 22} (20 + (n - 1)*3)\)D) There are 1,133 seats in total.How to write the formula for the sequence?
We know that we have 20 seats on the front row, and then we add 3 more on each row, so the formula will be:
\(A_n = 20 + (n - 1)*3\)
This gives the number of seats on the n-th row.
B) The last row has 83 seats, then we need to solve:
\(A_n = 20 + (n - 1)*3 = 83\\\\(n - 1)*3 = 83 - 20 = 63\\\\n - 1 = 63/3 = 21\\\\n = 21 + 1 = 22\)
So we conclude that there are 22 rows.
C) The total number of seats will be:
\(\sum_{n = 1\ to\ 22} (20 + (n - 1)*3)\)
D) Instead of using the sum above (we should add 22 terms) we use the general formula for the sum of N terms in an arithmetic sequence:
\(S_N = (N/2)*(2A_1 + (N - 1)*d)\)
In this case, we replace N by 22, and d is the common difference of the sequence, which we know is equal to 3, so we wil have:
\(S_{22} = (22/2)*(2*20+ (22 - 1)*3) = 11*(40 + 21*3) = 1,133\)
There are 1,133 seats in total.

Step-by-step explanation:
First, I solved for the bottom and top. 10 times 3 is 30. Then I doubled it because it's the same answer for the bottom and top. I got 60.
Next I solved for the sides. 4 times 3 is 12. Then I doubled it because it's the same answer for both sides. I got 24.
Lastly I solved for the front and back. 10 times 4 is 40. Then I doubled it because it's the same answer for both the front and back. I got 80.
After all this, I added everything together. 60 + 24 + 80 = 164.

Mr. A sold his land to Mr.B at a profit of 10%. Mr.B. sold it to Mr.C at a gain of 5%. Mr.C.paid N1240 more for the house than Mr. A paid. What did Mr. A paid.
Answers
Answer:
Mr. A initially paid approximately N8000 for the land.
Step-by-step explanation:
Step 1: Let's assume Mr. A initially purchased the land for a certain amount, which we'll call "x" in currency units.
Step 2: Mr. A sold the land to Mr. B at a profit of 10%. This means Mr. A sold the land for 110% of the amount he paid (1 + 10/100 = 1.10). Therefore, Mr. A received 1.10x currency units from Mr. B.
Step 3: Mr. B sold the land to Mr. C at a gain of 5%. This means Mr. B sold the land for 105% of the amount he paid (1 + 5/100 = 1.05). Therefore, Mr. B received 1.05 * (1.10x) currency units from Mr. C.
Step 4: According to the given information, Mr. C paid N1240 more for the land than Mr. A paid. This means the difference between what Mr. C paid and what Mr. A paid is N1240. So we have the equation: 1.05 * (1.10x) - x = N1240
Step 5: Simplifying the equation: 1.155x - x = N1240
Step 6: Solving for x: 0.155x = N1240
x = N1240 / 0.155
x ≈ N8000
Therefore, in conclusion, Mr. A initially paid approximately N8000 for the land.

The average rate of change is $22.50 per class
The total amount for 5 classes is $117.5The first class is $27.50 due to the studio charging $5 as the registration fee How to determine the average rate of changeThe table of values represent the given parameter
The average rate of change is calculated as
Rate = Change in T(c)/Corresponding change in c
So, we have
Rate = (50 - 27.50)/(2 - 1)
Rate = 22.50
The total amount for 5 classesWe start by calculating the function from
T(c) = mc + b
Where
m = Rate = 22.50
So, we have
T(c) = 22.5c + b
Using the points, we have
22.5 * 1 + b = 27.50
So, we have
b = 5
So, we have
T(c) = 22.5c + 5
For 5 classes, we have
T(5) = 22.5 * 5 + 5
T(5) = 117.5
Why the first class is 27.50The first class is 27.50 because the studio charges a registration fee of $5

Find the area of the frame.
Answers
Answer:
180cm²
Step-by-step explanation:
Area of the frame = area of the frame+ painting - area of painting.
Area of a rectangle = Length × Width
Area of the painting = 20cm×16cm
Area of the painting = 320cm²
Area of the paint+ frame = 25cm×20cm
Area of the paint+ frame = 500cm²
Area of the frame = 500cm²-320cm²
Area of the frame = 180cm²
Hence the area of the frame is 180cm²

the periodic transfer of a portion of the cost of an intangible asset to expense is referred to as
Answers
The periodic transfer of a portion of the cost of an intangible asset to expense is known as amortization. This is the process of spreading the cost of an intangible asset over its useful life, similar to how depreciation is used for tangible assets like buildings and equipment.
Intangible assets, such as patents, copyrights, and trademarks, do not have a physical existence but still have value to the company. Amortization recognizes the decline in value of these assets over time and helps to accurately reflect their impact on the company's financial statements.
The amount of amortization each period is calculated by dividing the cost of the asset by its estimated useful life. It is important for companies to track and properly account for their intangible assets, including amortization, as it can have a significant impact on their financial statements and overall financial health.

What is the highest value assumed by the loop counter in a correct for statement with the following header? for(i = 7; i <= 72; i += 7)
Select one:
a. 7
b. 70
c. 77
d. 72
Answers
The highest value assumed by the loop counter in a correct "for statement" with the given header is (b) 70.
The "for-statement" is ⇒for(i = 7; i <= 72; i += 7) ,
The loop starts with i = 7 and increases by 7 in each iteration until i becomes greater than 72.
So we can find the highest value of "i" assumed by the loop counter by solving the inequality i <= 72 for i.
⇒ i <= 72
Starting with i = 7 and increasing by 7 in each iteration,
We have,
⇒ i = 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77
The last value of i in the sequence, 77, is greater than 72, so the loop counter stops before reaching 77.
So, the highest value assumed by the loop counter in this for statement is : 70.
Therefore, the highest value assumed by the loop counter is (b) 70.

a solid lies inside the sphere x2 y2 z2 = 6z and outside the cone z = x2 y2 . write a description of the solid in terms of inequalities involving spherical coordinates
Answers
The sphere equation x^2 + y^2 + z^2 = 6z becomes:
ρ^2 = 6ρcos(φ)
The cone equation z = √(x^2 + y^2) becomes:
ρcos(φ) = ρsin(φ)
So, the solid lies within the region described by the inequalities:
ρ ≤ 6cos(φ) and ρcos(φ) ≥ ρsin(φ)
These inequalities, along with 0 ≤ θ ≤ 2π and 0 ≤ φ ≤ π, define the solid in spherical coordinates.
To describe the solid in terms of inequalities involving spherical coordinates, we first need to convert the given equations to spherical coordinates. In spherical coordinates, we have:
x = r sinθ cosϕ
y = r sinθ sinϕ
z = r cosθ
Substituting these values in the given equations, we get:
r² sin²θ cos²ϕ + r² sin²θ sin²ϕ + r² cos²θ = 6r cosθ
r cosθ = r² sin²θ cos²ϕ + r² sin²θ sin²ϕ
Simplifying these equations, we get:
r = 6 cosθ / (sin²θ cos²ϕ + sin²θ sin²ϕ + cos²θ)^(1/2)
r cosθ = r² sin²θ
Now, the solid lies inside the sphere x2 + y2 + z2 = 6z, which in spherical coordinates becomes:
r² = 6 cosθ
And the solid also lies outside the cone z = x2 y2, which in spherical coordinates becomes:
r cosθ >= r^4 sin^2(θ) cos^2(ϕ) + r^4 sin^2(θ) sin^2(ϕ)
r >= r^3 sin^2(θ) (cos^2(ϕ) + sin^2(ϕ))
r >= r^3 sin^2(θ)
Combining these inequalities, we get the description of the solid in terms of inequalities involving spherical coordinates:
r >= r^3 sin^2(θ) >= (6 cosθ)^(1/2)
This represents the solid that lies inside the sphere x2 + y2 + z2 = 6z and outside the cone z = x2 y2, in terms of inequalities involving spherical coordinates.

Answers
The task involves modifying the given code to implement binary search on an array in descending order. The logic of the code needs to be adjusted accordingly.
The task requires modifying the existing code to perform binary search on an array sorted in descending order. In the original code, the logic for the ascending order was based on comparing the key with the middle element of the list. However, in the descending order case, we need to adjust the logic.
To implement binary search on a descending array, we need to swap the order of the conditions in the code. Instead of checking if the key is less than the middle element, we need to check if the key is greater than the middle element. Similarly, the condition for equality also needs to be adjusted.
The modified code for binary search in descending order would look like this:
public static int binarysearch2(int[] list, int key) {
int low = 0;
int high = list.length - 1;
while (high >= low) {
int mid = (low + high) / 2;
if (key > list[mid])
high = mid - 1;
else if (key < list[mid])
low = mid + 1;
else
return mid;
}
return -1; // Not found
}
By swapping the conditions, we ensure that the algorithm correctly searches for the key in a descending ordered array.
