The statements are true, as they can be demonstrated using the definitions of continuity, limit, and derivative.

Let f and g be two functions with domain over the real numbers and let a be a real number.

The following statement is true: If f(x) is continuous at a, then f(a) is differentiable at a. This can be demonstrated by the definition of continuity at a point. If f is continuous at a, then for any ε > 0 there exists a δ > 0 such that |f(x) - f(a)| < ε if 0 < |x-a| < δ. This implies that the function is differentiable at a, since the limit of the difference quotient, lim (f(x) - f(a))/(x-a) exists as x approaches a.

The following statement is true: If lim f(z) = 0 and lim g(a) = 0, then lim (f(x)/g(x)) = 0. This can be demonstrated by the definition of a limit. Since the limit of f(x) as x approaches a is 0, then for any ε > 0 there exists a δ > 0 such that |f(x)| < ε if 0 < |x-a| < δ. Similarly, since the limit of g(x) as x approaches a is 0, then for any ε > 0 there exists a δ > 0 such that |g(x)| < ε if 0 < |x-a| < δ. Thus, |f(x)/g(x)| < ε/ε = 1 if 0 < |x-a| < δ, and the limit of f(x)/g(x) as x approaches a is 0.

The following statement is true: If f'(1) exists, then the limit lim f(x) is f(1). This can be demonstrated by the definition of the derivative. If f'(1) exists, then the limit of the difference quotient, lim (f(x) - f(1))/(x-1), exists as x approaches 1. Thus, |f(x) - f(1)| < ε if 0 < |x-1| < δ. This implies that the limit of f(x) as x approaches 1 is equal to f(1).

Associate property of real numbers illustrated by the equation (2+x)+3=2+(x+3).

What is  Associate property ?

Associative property is defined as, when more than two numbers are added or multiplied, the result remains the same, irrespective of how they are grouped.

For instance,

2 × (7 × 6) = (2 × 7) × 6

Associative property for addition implies that regardless of how numbers are grouped, the final sum of the numbers will remain the same. This can be expressed as:

(x + y) + z = x + (y + z)

Associative property for multiplication implies that regardless of how numbers are grouped, the final product of the numbers will remain the same. This can be expressed as:

p × (q × r) = (p × q) × r

The capacity of the two containers can be measured with a jar with a maximum capacity of 20 litres.

In this problem we find the case of two containers with different capacity, one with a capacity of 40 litres and other with a capacity of 60 litres, we can measure each of them based on the number of adds needed to fill each container. The number of adds (n) is equal to the container capacity (C), in litres, divided by the jar capacity (c), in litres:

n = C / c

If we assume that the number of adds is a natural numbers, then we determine the greatest common factor of both container capacities. First, decompose each number related to each container:

40 = 2³ × 5

60 = 2² × 3 × 5

Second, find the common factors and create the resulting product:

G.C.F. = 2² × 5

The program calculates the user's age in 2050 by declaring and initializing three integer variables (myNewAge, myCurrentAge, and currentYear) and using them in an expression to determine the user's age in 2050.

Here is the C++ code that implements the instructions:

#include <iostream>

int main() {

 int myCurrentAge = 29;

 int currentYear = 2023;

 int myNewAge = myCurrentAge + (2050 - currentYear);

 std::cout << "My Current Age is " << myCurrentAge << ". ";

 std::cout << "I will be " << myNewAge << " in 2050." << std::endl;

 return 0;

We can find a matrix P such that PTAP orthogonally diagonalizes A, and the diagonal entries of PTAP are the eigenvalues of A, verifying that the diagonal form of A is correct.

We can orthogonally diagonalize a matrix A by finding a matrix P such that PTAP is orthogonal. An orthogonal matrix is a matrix whose columns are orthogonal unit vectors. This means that the dot product of any two columns is 0.

Let's calculate the matrix P to orthogonally diagonalize A. We will use the Gram-Schmidt process to calculate the orthonormal vectors for the columns of P.

Let v1 = (7,1) be the first column vector of A. We will use this vector to calculate the first column of P. We normalize v1 and get an orthonormal vector u1 = (7/sqrt(50), 1/sqrt(50)). We set the first column of P to be u1.

For the second column, we take the second column vector of A and subtract its projection on u1. This gives us a new vector v2 = (7, -6). We normalize v2 and get an orthonormal vector u2 = (7/sqrt(73), -6/sqrt(73)). We set the second column of P to be u2.

Now, we have the matrix P = [[7/sqrt(50), 7/sqrt(73)], [1/sqrt(50), -6/sqrt(73)]]. We can verify that the dot product of the columns of P is 0, which shows that P is an orthogonal matrix.

We can now calculate the product PTAP. We get PTAP = [[7^2/50+7^2/73, 7*7/50-6*7/73], [7*7/50-6*7/73, 7^2/50+6^2/73]]. We can see from this matrix that the diagonal entries are equal to the eigenvalues of A, which were 7 and 1. This shows that PTAP is a diagonal matrix which orthogonally diagonalizes A.

We can find a matrix P such that PTAP orthogonally diagonalizes A, and the diagonal entries of PTAP are the eigenvalues of A, verifying that the diagonal form of A is correct.

The probability of a Type I error, increases the size of the critical region, and increases the probability that the sample will fall into the critical region.

The alpha level (or significance level) is a probability value used to determine the level of statistical significance of a test. Increasing the alpha level from a = .01 to a = .05 means that the probability of a Type I error (also known as a false positive) increases. This is because the critical region, or range of values that represents a statistically significant result, increases in size.

The critical region is calculated by subtracting the alpha level from 1, then subtracting the result from the alpha level. For a = .01, the critical region is calculated by 1 - .01 = .99, and then .99 - .01 = .98. For a = .05, the critical region is calculated by 1 - .05 = .95, and then .95 - .05 = .90.

The increase in the critical region size means that there is an increased probability that the sample will fall into the critical region, and yield a statistically significant result. This is because the critical region has become larger, meaning that there is a greater chance that the sample will lie within it. In summary, increasing the alpha level from a = .01 to a = .05 increases the probability of a Type I error, increases the size of the critical region, and increases the probability that the sample will fall into the critical region.

The 3.13%  interest rate will cause his money to double in approximately 23 years.

The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.

Given that Arnulfo deposited $55 into a savings account for which interest is compounded semiannually.

According to the rule of 72, we should divide 72 by the interest rate to determine how many years it will take to double our money at a specific interest rate (r).

time is taken to double the money = 72/r,

where r represents the interest rate and time is in years.

As we have been given that it will take approximately 23 years to double Arnulfo's money, so we can set an equation as:

Solution to the question of figure : c

Step-by-step explanation:

Using Pythagoras theorem, The missing side of the right triangle is 4,9 mm long.

Pythagoras' Theorem states that the square of the hypotenuse side in a right-angled triangle is equal to the sum of the squares of the other two sides. The Perpendicular, Base, and Hypotenuse are the names of the three sides of this triangle. The hypotenuse in this example is the longest side because it is located across from the 90° angle. A right triangle's positive integer sides (let's say sides a, b, and c) are squared to produce a Pythagorean triple equation.

Right triangles are what the provided triangle is.

The Pythagorean Theorem is used:

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex](5)^{2} + (7)^{2} = c^{2}[/tex]

25 + 49 =[tex]c^{2}[/tex]
