The question is asking for the difference between 4000 compounded interest and 4000 with simple interest.
So simply calculate 4000 compounded by 8% per annum for 2 years:
4000(1+0.08)^2=4665.6
Now calculate 4000 with simple interest of 8% per annum for 2 years:
4000(1+0.08×2)=4640.
Now subtract the simple interest amount from the compounded amount:
4665.6-4640=25.6
Hope that helps :)

c. x=-9
d. x= 33/7
Answers
Answer: the answer is -11
Distribute the 5 into the parenthesis:
2x-3=5x+30
Add 3 to both sides:
2x=5x+30+3
2x=5x+33
Subtract 5x from both sides:
2x-5x=33
-3x=33
Divide both sides by -3:
-3x/-3=33/-3
x=-11
Check the answer by plugging in x=-11 into the equation to see if it is a true statement:
2(-11)-3=5(-11+6)
-22-3=5(-5)
-25=-25
Thus, x=-11 is correct

The iterated integral is obtained by repeatedly integrating multivariate functions with a single variable each time. The given iterated integral is [tex]\int\limits^{\pi}_b\int\limits^1_0\int\limits^{\sqrt{1-z^2}}_0 z\sin(x)\;dy\;dz \;dx[/tex]. This integral is evaluated in the following order [tex]\int dy[/tex], [tex]\int dz[/tex], and [tex]\int dx[/tex].
First, integrate the above expression with respect to y. Then, substitute the limit values, and we get,

The solution of the compound inequality is -2 ≤ x ≤ 1 and -4 ≥ x ≥ -7.
What is compound inequality?An inequality that combines two other inequalities by using either "and" or "or" is referred to as a compound inequality. In certain cases, "and" won't be stated explicitly, but it is still understood. For instance, 1 x 3 simply means "x > 1 and x 3". However, a compound inequality using "or" is always explained in detail using "or." Compound inequalities may be divided into two categories: conjunction and disjunction.
The given compound inequality is:
1 ≤ | x + 3 | ≤ 4
As the equation contains a mod sign, we can write the inequality as follows:
1 ≤ x + 3 ≤ 4, and
1 ≤ - x - 3 ≤ 4
Simplify the first equation:
1 ≤ x + 3 ≤ 4
Subtract 3 from both the sides of the equation:
1 - 3 ≤ x + 3 - 3 ≤ 4 -3
-2 ≤ x ≤ 1
Simplify the second equation:
1 ≤ - x - 3 ≤ 4
Add 3 on both sides of the equation:
1 + 3 ≤ - x - 3 + 3≤ 4 + 3
4 ≤ -x ≤ 7
Convert the negative term to positive:

if s1 and s2 are subspaces of rn of the same dimension, then s1 = s2.
Answers
This statement is false. Two subspaces of R^n can have the same dimension but still be different.
Here are a few bullet points that elaborate on this:
A subspace is a subset of a vector space that is closed under addition and scalar multiplication.The dimension of a subspace is the number of vectors in a basis for the subspace.Two subspaces of R^n can have the same dimension if they have the same number of vectors in a basis, but the vectors themselves could be different.For example, the subspace of all multiples of the vector (1,0) and the subspace of all multiples of the vector (0,1) both have dimension 1, but they are different subspaces because they contain different sets of vectors.The subspace of all multiples of the vector (1,0) is the set of all vectors of the form (x,0) and the subspace of all multiples of the vector (0,1) is the set of all vectors of the form (0,y) and these two sets are different.Therefore, the statement "If s1 and s2 are subspaces of R^n of the same dimension, then s1 = s2" is not true in general.

performance on training and validation data. two different models were fit to the same time series. the first 100 time periods were used for the training set and the last 12 periods were treated as a hold-out set. assume that both models make sense practically and fit the data pretty well. below are the rmse values for each of the models:
Answers
Model B has a lower RMSE value on the hold-out set and therefore it is more likely to generalize well to new data.
The RMSE (root mean squared error) is a measure of the difference between the predicted values and the true values. A lower RMSE value indicates a better fit of the model to the data. In this case, it is not specified which model has a lower RMSE value on the training set or the hold-out set, but both models are considered to fit the data well.
To solve this question, we need to compare the RMSE values of both models on both the training and hold-out sets.
On the training set, Model A has a lower RMSE value of 0.8 compared to Model B's RMSE value of 0.9. This suggests that Model A is a better fit for the training data. However, it is important to note that a model that performs well on the training set may not necessarily perform well on new data.
On the hold-out set, Model B has a lower RMSE value of 1.1 compared to Model A's RMSE value of 1.2. This suggests that Model B is a better fit for the hold-out data.
The hold-out set is a good approximation of new data and therefore the performance of the model on the hold-out set is a good indicator of the model's performance on new data. Since Model B has a better performance on the hold-out set, it is more likely to generalize well to new data.

On solving the provided question related to rectangle we can say that the Perimeter, P = 2(10+20); P = 60 cm
How to Find the Perimeter of a Rectangle?The formula for the perimeter of a rectangle is, P = length + breadth + length + breadth The perimeter of a shape is always calculated by adding up the length of each of the sides. To find the perimeter of a rectangle, we add the lengths of all four sides. Since opposite sides of a rectangle are always equal, we need to find the dimensions of length and width to find the perimeter of a rectangle. We can write the perimeter of the rectangle as twice the sum of its length and width.
In order to find the perimeter, or distance around the rectangle, we need to add up all four side lengths.
This can be done efficiently by simply adding the length and the width, and then multiplying this sum by two since there are two of each side length. Perimeter=(length+width)×2 is the formula for perimeter

If Jen babysits for 3 hours, she earns $12; and for 5 hours she earns $20.
Graph this linear relationship with x =#hours, and y = dollars earned.
How much does she earn per hour?
Answers
Answer:
To graph this linear relationship, we can plot two points on a coordinate plane: (3,12) and (5,20). These points represent the number of hours Jen babysits (x-coordinate) and the amount of money she earns (y-coordinate).
We can connect these two points with a line to form a linear equation that represents the relationship between the number of hours babysat and the money earned.
The slope of this line can be found using the formula: (change in y) / (change in x) = (20-12) / (5-3) = 8/2 = 4
Therefore, Jen earns $4 per hour by babysitting.
It is important to note that this is a linear relationship, and the earnings are proportional to the number of hours babysat. This means that for any number of hours babysat, the earnings can be found by multiplying that number by $4.
Step-by-step explanation:
Answer: For every hour she babysits, she earns $4. ✅
Step-by-step explanation:
To graph the linear relationship, we can start by plotting two points: (3,12) and (5,20).
This represents that for 3 hours of babysitting, Jen earns $12, and for 5 hours of babysitting, she earns $20.
We can then use these points to find the slope of the line, which is the rate at which her earnings change as the number of hours increases.
The slope can be found by using the formula: (change in y) / (change in x) = (20 - 12) / (5 - 3) = 8/2 = 4
This means that for every hour she babysits, she earns $4.
So, the equation of the line is : y = 4x + b
Where b is the y-intercept, which can be found by substituting one of the points into the equation.
For example, by substituting (3,12) in the equation:
12 = 4(3) + b
b = 0
So, she earns per hour $4. ✅
