The projection of vector v on u is =[tex]\=109/\sqrt{113}(2i+10j+3k)[/tex]

Sometimes the inner product and the dot product are considered to be the same. The formal definitions of projection and rejection employ the inner product rather than the dot product whenever they don't coincide. The concepts of projecting a vector onto another and rejecting a vector from another can be applied to the concepts of projecting a vector onto a plane and rejecting a vector from a plane for a three-dimensional inner product space.

A vector's orthogonal projection on a plane is the vector's projection on that plane. A vector is rejected from a plane when it is projected in an orthogonal direction on a straight line. They're both vectors. The first is orthogonal to the plane, while the second is parallel.

Answer:

28

Step-by-step explanation:

The slope of a line represents the rate of change between two variables. In the case of Superior Segway Tours, the cost of the tour is changing as the number of hours for the tour changes. The rate of change can be calculated by dividing the change in the dependent variable (cost) by the change in the independent variable (hours). In this case, the slope is $28 per hour. This means that for every hour that is added to the tour, the cost will increase by $28.

The slope of this situation can be represented as the change in cost (y-axis) per unit change in time (x-axis). The slope in this case would be $28 per hour.

The number of zeros of the polynomial p(x) is 3.

A polynomial is a mathematical expression that solely uses the addition, subtraction, and multiplication operations to combine variables (commonly called coefficients) and variables (often called x). The variables are raised to non-zero, and the coefficients can be any real value.

The number of x-intercepts, or the places where the graph crosses the x-axis, is equal to the number of polynomial roots, also known as zeros.

We can see from the above graph that the polynomial p(x) has three x-intercepts, which indicates that it has three roots or zeros. Consequently, the polynomial p(x) has three zeros.

After maxing x as a subject the solution becomes: x = z³ + √d 3a. This can be solved using the concept of solving equation.

Equations simultaneously, or a system of equations Multiple equations in algebra must be solved simultaneously. There must be an equal number of equations and unknowns for a system to have a singular solution. When two or more equations use the same variables, they are said to be in a system of equations. Graphing, substitution, and elimination are the three techniques used to solve systems of equations.

For instance, two equations with the identical variables, x and y, are x + y = 12 and 2x + 5y = 8. They are an equalization system.

Using basic arithmetic operations, the missing terms are a)  7/5 and b) 19/14.

There are four basic arithmetic operations which are addition, subtraction, multiplication, and division. These operations can be applied to whole numbers and fractions.

a) 14/16  x  8/7= y x  5/7

In order to solve for y, the numerator and denominator on LHS are simplified and multiplied:

14/16  x  8/7=  7/8  x  8/7 = (7 x 8)/(8 x 7)

As there are same numbers in both numerator and denominator, they are cancelled:

(7 x 8)/(8 x 7)=1

Hence,

1= y x  5/7

Multiply both side by 7/5

7/5  x 1= y x  5/7  x  7/5

y=  7/5

b) 1/2+  4/7= y -2/7

In order to solve for y, add the fraction on LHS:

1/2+  4/7=  ((7 x 1)+(4 x 2))/((2 x 7)) = (7+8)/14=15/14

Hence,

15/14= y -2/7

Add 2/7 to both sides:

15/14+  2/7= y -2/7  +  2/7

y = (15+4)/14=19/14

The cosine ratio, also known simply as the cosine, is a trigonometric function that represents the ratio of the adjacent side to the hypotenuse of a right triangle.

It is defined as cos(θ) = adjacent side/hypotenuse, where θ is the angle between the adjacent side and the hypotenuse.

Reference angle (∅) = A

Length of adjacent side = 2

An exponential function would better approximate the data described about the volume of a gas.

The relationship between the volume of a gas and its temperature is described by the Ideal Gas Law, which states that the volume of a gas is proportional to its temperature raised to the power of the ratio of specific heat to the universal gas constant. Therefore, as the temperature of a gas increases, its volume will increase exponentially.

The data given in the problem, with the volume increasing as the temperature increases, supports the use of an exponential function to model the relationship between temperature and volume. On the other hand, a linear function, which models a constant rate of change, would not accurately capture the exponential increase in volume as the temperature increases.

The inverse of the function is f⁻¹ ( x ) = ( x + 5 )² and the domain is x ≥ 0

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is given as

f ( x ) = √x - 5   be equation (1)

On simplifying the equation , we get

The probability of having n-1 failures before the first success in a Geometric distribution, given a specific probability p.

The formula (1-p)n-1 represents the probability of having n-1 failures (or successes, depending on which outcome the probability p is associated with) in a Geometric distribution. For example, if p=0.3, then the formula (1-p)n-1 would represent the probability of having two failures before the first success. This would be equal to (1-0.3)2-1, or 0.49. This means that there is a 49% chance of having two failures before the first success in this example. In general, this formula can be used to calculate the probability of having n-1 failures before the first success in a Geometric distribution, given a specific probability p.

Answer: The inverse of the function k(x)=x²-3 is k^(-1)(x)=±√(x+3). The domain restrictions for the inverse are x≥-3, since the square root is only defined for non-negative values.

The inverse of a function is the reflection of the original function over the line y=x. To find the inverse of k(x)=x²-3, we first swap the x and y variables: y=x²-3. Then, we solve for x: x=±√(y+3). This gives us the inverse function k^(-1)(x)=±√(x+3).

However, it is important to note that the square root function is only defined for non-negative values. Therefore, we must restrict the domain of the inverse function to x≥-3. This means that the inverse function can only be applied to input values that are greater than or equal to -3. For values less than -3, the inverse function is undefined.

Step-by-step explanation:

==> y = x² - 3

Swap x and y

x = y² - 3

x + 3 = y²

y² = x + 3

Replace Swap x and y again to get the inverse as a function of x

On a principal of $100,000.00 with compound interest accrued at a rate of 7% per year compounded continuously over 4 years, the total sum is $132,312.98.

The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest. A = P(1 + r/n)^nt, where P is the principal balance, r is the interest rate, n is the number of times interest is compounded annually, and t is the number of years, which is the formula for compound interest.

Given,  You have an inheritance of $100,000 from your grandparents, you must invest the money in a mutual fund until you are 21 years old, which will pay an annual interest rate of r% compounded continuously.

From the general formula of compound interest:

A = Pe^rt,

where P is the principal balance,

r is the interest rate,

n is the number of times interest is compounded annually,

t is the number of years

In our case,

P = 100,000

t = 21 - 17 = 4

n = 12 for compounded continuously

thus,

A = 100,000(2.71828)^r4

For the value of r = 7

A = 100,000.00(2.71828)^(0.07)(4)

A = $132,312.98

Therefore, The total amount accrued, principal plus interest, with compound interest on a principal of $100,000.00 at a rate of 7% per year compounded continuously over 4 years is $132,312.98.
