Answer:

\(x = 5 + \sqrt{17 } \\ 4\)

Answer:

  5 1/3

Step-by-step explanation:

You want the value of the definite integral of (x² +5) on the interval [0, 1].

The power rule applies:

  ∫(x^n)dx = (x^(n+1))/(n+1)

This means the integral is ...

  \(\displaystyle \int_0^1{(x^2+5)}\,dx=\left(\dfrac{x^3}{3}+5x\right)_0^1=\dfrac{1}{3}+5\)

The value of y is 5 1/3.

Answer:

the answer is : x=2 not 100% sure

To determine who got the most questions correct, we need to compare the fractions or percentages of correct answers each student got. However, the comparison between James and Rebecca depends on the total number of problems each had, which is not provided. Here's what we know:

- James: 3/4 or 75%

- William: 85%

- Rebecca: 1/3 of what James got (since James got 3 times as many problems correct as she did), which would be 1/3 * 75% = 25%

- Katelyn: 7/10 or 70%

So, based on the percentages, William got the highest percentage of problems correct with 85%.

However, if we're talking about the absolute number of problems correctly answered, we can't conclusively determine who got the most questions correct without knowing the total number of questions each student had on their quiz. For instance, if James had 100 questions on his quiz and Rebecca had 10, then James would have answered more questions correctly than Rebecca even though his percentage is lower.

The statement that is TRUE based on the given facts is that the customer's fixed income portfolio has experienced a greater decline in value than the decrease in the Consumer Price Index (CPI).

To elaborate, the customer's fixed income portfolio has dropped by 5% over the past 4 years. This means that the value of their portfolio has decreased by 5% compared to its initial value. On the other hand, the Consumer Price Index (CPI) has dropped by 2% during the same period. The CPI is a measure of inflation and represents the average change in prices of goods and services.

Since the customer's portfolio has experienced a decline of 5%, which is larger than the 2% drop in the CPI, it indicates that the value of their portfolio has decreased at a higher rate than the general decrease in prices. In other words, the purchasing power of their portfolio has been eroded to a greater extent than the overall decrease in the cost of goods and services measured by the CPI.

This vector function removes an item from a vector is erase (option c).

The vector function that removes an item from a vector in most programming languages, including C++, is typically called "erase." The erase function is used to remove elements from a vector based on a specified position or range.

The erase function can take different forms depending on the programming language and vector implementation. For example, in C++, the erase function is a member function of the vector class and can be used in the following ways:

vector.erase(position) - Removes the element at the specified position.

vector.erase(first, last) - Removes elements in the range defined by the iterators 'first' and 'last'.

Using the erase function allows you to remove elements from a vector and adjust the size of the vector accordingly. The correct option is c.

For subspaces to be orthogonal, their intersection must be the zero vector.

Therefore, we can determine whether the subspaces are orthogonal by checking if the dot product between any two vectors, one from each subspace, is equal to zero.
For S_1 and S_2, the dot product between [4 5 -4] and [5 -4 0] is not equal to zero, so they are not orthogonal.
For S_1 and S_2, the dot product between [1 1 1 1] and [-1 1 -1 1] and [0 2 -2 0] is equal to zero, so they are orthogonal.
For S_1 and S_2, the dot product between [0 0 2 1] and [3 2 0 0] and [0 1 -2 2] is equal to zero, so they are orthogonal.
Two subspaces are orthogonal if their vectors have a dot product of zero. For S_1 = span {[4 5 -4], [0 1 1]} and S_2 = span {[5 -4 0]}, the dot products are (4)(5) + (5)(-4) + (-4)(0) = 0. They are orthogonal.
For S_1 = span {[1 1 1 1]} and S_2 = span {[-1 1 -1 1], [0 2 -2 0]}, the dot product of S_1 and both vectors in S_2 is non-zero. They are not orthogonal.
For S_1 = span {[0 0 2 1], [0 0 1 -2]} and S_2 = span {[3 2 0 0], [0 1 -2 2]}, the dot product of all pairs of vectors is zero. They are orthogonal.

The symbols x, y, and z are examples of variables in an instruction like z = x + y.

A variable is a term that signifies anything that can be varied or altered. In programming, variables are utilized to hold values that might be modified and used in later code.

A variable is a name that identifies a memory location where data is stored. It can be changed anytime. Variables are commonly used in mathematical expressions, such as those seen in algebra. For example, x + 150 = 300In this instance, x is the variable. 150 and 300 are constants.

Answer:

Hey there!

To solve this problem, we want to find the LCM (least common multiple) of the two numbers.

The numbers are 25 and 30.

25=5x5

30=2x3x5

LCM is 5x5x2x3, or 150.

Thus, in 150 minutes is when the next bus will leave.

150 mins is equal to 2 hours and 30 mins, or 2.5 hours.

8 AM + 2.5 hrs = 10:30 AM.

Thus, the next time the busses leave together would be at 10:30 AM.

Ii's letter A

Step-by-step explanation:

If functions f(x) = 3x - 2 and g(x) = 2x + 1 then (f+g)(x) value is 5x-1, Option A is correct.

A relation is a function if it has only One y-value for each x-value.

The given functions are f(x) = 3x - 2 and g(x) = 2x + 1

We have to find the function (f+g)(x)

By property of the function (f+g)(x) = f(x) + g(x)

Now plug in the values of function f(x) and g(x)

(f+g)(x)= 3x-2+2x+1

Combine the like terms

(f+g)(x)= 5x-2+1

= 5x-1

Hence, if functions f(x) = 3x - 2 and g(x) = 2x + 1 then (f+g)(x) value is 5x-1, Option A is correct.

Step-by-step explanation:

To find the directional derivative of the function f(x, y) = y in the direction of (5, 6) at the point (x, y) = (1, -4), we can use the dot product between the gradient of f and the given direction vector.

The gradient of f(x, y) is ∇f = (∂f/∂x, ∂f/∂y), where ∂f/∂x represents the partial derivative of f with respect to x, and ∂f/∂y represents the partial derivative of f with respect to y.

In this case, ∂f/∂x = 0 (since f(x, y) = y does not depend on x), and ∂f/∂y = 1. The direction vector (5, 6) has a magnitude of √(5² + 6²) = √(61).

The directional derivative is given by the dot product:

Df = ∇f · (5/√(61), 6/√(61)).

Substituting the values of ∇f and the direction vector, we have:

Df = (0, 1) · (5/√(61), 6/√(61)).

Taking the dot product, we get:

Df = 0*(5/√(61)) + 1*(6/√(61)) = 6/√(61).

Calculating this value to at least 4 decimal places, we have:

Df ≈ 0.7700.

Therefore, the directional derivative of the function f(x, y) = y in the direction of (5, 6) at the point (x, y) = (1, -4) is approximately 0.7700.

This theorem states that:

\(a^2+b^2=c^2\)

In this diagram, notice how there are two smaller triangles that create the large triangle.

To find a and b, we can look at the two small triangles instead of seeing everything as a whole.

Let the top triangle be Triangle A and the bottom triangle be Triangle B.

Solve for a using the Pythagorean theorem:

\(a^2+b^2=c^2\\12^2+6^2=a^2\\a=\sqrt{12^2+6^2}\\a=13.42\)

Solve for b using the Pythagorean theorem:

\(a^2+b^2=c^2\\6^2+3^2=b^2\\b=\sqrt{6^2+3^2}\\b=6.71\)

a = 13.42

b = 6.71
