The value of the scalars a = 3 , and b = -1  .

In the question ,

it is given that

u = (1, −1, 3, 5) and v = (2, 1, 0, −3)

and the equation au + bv = (1, −4, 9, 18)

Substituting the first value of u that is u=1 and substituting the first value of v that is v=2 ,

we get a+2b=1     ....(i)

Now , Substituting the second value of u that is u= -1 and substituting the second value of v that is v=1 ,

we get -a+b= -4      ...(ii)

Solving the equations (i) and (ii)

Adding both the equations we get

a-a+2b+b=1-4

3b= -3

b= -1

a+2b=1

put b= -1

a+2(-1)=1

a-2=1

a=3.

Answer:

Bring the variable to the left and the remaining values to the right to define the value of x. If m/8 = 86° and m/4 = (4x + 2)° then value of  x = 21.

Any of the algebraic expressions, including addition, subtraction, multiplication, and division, should be used. Bring the variable to the left and the remaining values to the right to determine the value of x. To determine the outcome, simplify the values.

Let the m/8 = 86° and m/4 = (4x + 2)°

m ∠4 = m ∠8 (Corresponding angles are equal)

To estimate the value of x

4x + 2 = 86

Substracting both sides of the equation by 2, we get

4x + 2 - 2 = 86 - 2

simplifying the above equation,

4x = 86 - 2

4x = 84

Dividing both sides of the equation by 4, we get

4x / 4 = 84 / 4

x = 21

Therefore, the value of x = 21.

The effective annual yield if the interest is compounded daily is 10.5155 %.

The annual interest rate or rate of return that an investor is entitled to over a particular time period is known as effective annual yield.

​In the case of daily, there are 360 days in a year.

Therefore, making n = 360.

Therefore, the effective annual yield if the interest of 10% is compounded daily when r = 10 % and n = 360 will be:

Y = ( 1 + r/n )ⁿ - 1

Y = ( 1 + 0.1 / 360 )³⁶⁰ - 1

Y = ( 1 + 0.000277 )³⁶⁰ - 1

y = 1.105155 - 1

Y = 0.105155

However, since it is in decimal form, we must first multiply it by 100 before adding the symbol "%" after the last digit of the value.

Therefore,

Y = 0.105155 × 100%

Y = 10.5155 %

Therefore, the effective Annual Yield is 10.5155 %

To graph the given polynomial function, we can plug in any values of x to find values of h(x). The graph is shown below:

We also note that the x-intercept is the point on the x-axis, while the y-intercept is the point on the y-axis. Hence,

x-intercepts: (1,0), (-2,0)

y-intercept: (0,-4)

Tt can also be noted that (x − 1) occurs 3 times while (x+2) occurs 2 times. Hence, x=1 has a multiplicity 3, while x=-2 has a multiplicity 2.

Compound interest refers to the interest added to a loan or deposit. It is the concept that we use every day the most regularly. For an amount, compound interest is computed using both the principal and accrued interest. This is the primary difference between compound and simple interest.

Compound interest is the type of interest that is calculated using both the principal and the interest that has accumulated over the preceding period. In contrast to simple interest, compound interest does not factor in the principal when calculating the interest for a subsequent period.

In mathematics, compound interest is frequently referred to as C.I.

It is possible to compute interest using both the initial principle and interest that has accumulated over time.

Compound interest is calculated mathematically as Amount - Principal, where

Amount = Principal*(1 + (r/n))t, where r is the rate of interest, n is the number of times interest is compounded annually, and t is the number of years, and Principal is the initial amount deposited.

Given, Principal = £23000
Rate of interest = 6%
Number of times interest is compounded per year = 1
Number of years = 5
Using above literature, Amount = 23000(1 + (6/1))^5  = 23000*16807 = £ 386,561,000.
Thus, Compound Interest = £386,561,000 - £23000 = £386,538,000.

A numeral is a sign, combination of symbols, or figure that represents a number. It can be a mathematical numbering system.

A numeral's value is determined by the number it represents. All modern numbers cannot be represented by all number systems; Roman numerals, for instance, do not have a zero. A numeral system should, in theory, be able to: Represent a useful set of numbers (e.g. all integers, or rational numbers).

Supposing that the other square has a length of 6 units, applying the Pythagorean Theorem, it is found that:

The length of the hypotenuse side is of 10 units.

The Pythagorean Theorem is a geometry axiom that relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, stating that the hypotenuse squared is the sum of the legs squared, according to the following equation:

[tex]h^2 = l_1^2 + l_2^2[/tex]

In the context of this problem, we have that the legs have lengths defined as follows:

Hence the length of the hypotenuse can be found as follows:

h² = 6² + 8²

h² = 36 + 64

h² = 100

h = sqrt(100)

h = 10 units.

This problem is incomplete and could not be found on any search engine, hence we are going to suppose that the other leg of the triangle has a length of 6 units.
