The linear equation is 45x+50

Linear equation is the equation having the degree 1

Given that the charge per computer repair service  is $50

The charge per hour of work is $ 45

We need to show the linear equation that  expresses the total amount of money Charlie earns per computer is y

So , Let the number of hours be x

Therefore, the Charlie working hours charge will be 45x

The total amount of money Charlie earns per computer is y

Therefore the linear equation will be

y = 50+45x  

Where y = Total amount of money

x =  number of hours

Hence the linear equation is y = 45x+50

Step-by-step explanation:

To find a slope of a line, you have to identify x and y variables:

We use the formula;

m = ∆y/∆x

= (y2 - y1)/(x2 - x1)

Substitute the values into the formula above.

m = (7 - 3)/(2-4)

= 4/-2

= -2

Therefore, the slope of the line is passing through points (4,3) and (2,

A irrational number is a number that can't be expressed as a ratio of two whole numbers. That's it.

For examples (in increasing order of difficulty)

1 is a rational number because it is 1/1

0.75 is a rational number because it is equal to 3/4

2.333... (infinite number of digits, all equal to three) is rational because it is equal to 7/3.

sqrt(2) is not a rational number. This is not completely trivial to show but there are some relatively simple proofs of this fact. It's been known since the greek.

pi is irrational. This is much more complicated and is a result from 19th century.

As you see, there is absolutely no mention of the digits in the definition or in the proofs I presented.

Now the result that you probably hear about and wanted to remember (slightly incorrectly) is that a number is rational if and only if its decimal expansion is eventually periodic. What does it mean ?

Take, 5/700 and write it in decimal expansion. It is 0.0057142857142857.. As you can see the pattern "571428" is repeating in the the digits. That's what it means to have an eventually periodic decimal expansion. The length of the pattern can be anything, but as long as there is a repeating pattern, the number is rational and vice versa.

As a consequence, sqrt(2) does not have a periodic decimal expansion. So it has an infinite number of digits but moreover, the digits do not form any easy repeating pattern.

The surface area of the parallelpiped is equal to 800 square units.

The surface area of the parallelpiped seen in the picture is equal to the sum of the areas of its six faces, which are combination of areas of quadrilaterals and triangles. There are four parallelograms and two squares. Thus, the surface area of the solid is:

A = 2 · 8 · 20 + 2 · 7 · 20 + 2 · 10²

For the expression to be equal to the original one, we have;

[(x + 1) * 5(x - 1)(x + 4)]/[(x - 1) * 7x]

We are given the algebraic expression;

(5x² + 25x + 20)/(7x)

Now, looking at the numerator, a common factor to all terms is 5. Thus, we will factorize it out to get;

5(x² + 5x + 4) = 5((x + 1)(x + 4))

Now, we see that the expression that simplifies the algebra is given as;

[(x² + 2x + 1) * ( )]/[( ) * (7x² + 7x)]

Now, the numerator and denominator can be factorized to get;

[(x + 1)(x + 1) * ( )]/[( ) * 7x(x + 1)]

Thus, x + 1 will cancel out to get;

[(x + 1) * ( )]/[( ) * 7x]

For the expression to be equal to the original one, we have;

[(x + 1) * 5(x - 1)(x + 4)]/[(x - 1) * 7x]

The expression of the equation 4(x - 8) + y = 9(x - 2) in slope intercept form is; y = 5x + 14

We want to express 4(x - 8) + y = 9(x - 2) in slope intercept form of y = mx + b.

Let us expand the equation to get;

4x - 32 + y = 9x - 18

Isolate y to get;

y = 9x - 4x - 18 + 32

y = 5x + 14

Answer: about 260 Lb

Step-by-step explanation:

The Kernel Function K (x,x') written as a function of the dot product x *x' is  K (x, x') = Z². See the working below.

A kernel function is a way for taking input data and transforming it into the needed form of processing data.

The term "kernel" refers to a collection of mathematical functions used in Support Vector Machine to provide a window to alter data.

Given x = [x₁, x₂][tex]^{T}[/tex]

β(x) = [x²₁, √2 x₁ x₂, x²₂]

K (x₁, x') = β(x)[tex]^{T}[/tex] β(x')[tex]^{T}[/tex]

Hence, X' =  [x₁, x₂][tex]^{T}[/tex]

→ β(x') = [x'²₁, √2 x'₁ x'₂, x'²₂]

K (x, x') = [x²₁, √2 x₁ x₂, x²₂][tex]^{T}[/tex]  [x'²₁, √2 x'₁ x'₂, x'²₂]

K (x, x') = [x²₁, [x'²₁ + 2x₁ x₂ x'₁ x'₂ + x²₂ x'²₂

Because Z = x · x' (dot product of x·x')

= x₁ x'₁ + x₂x₂'

Expressing K (x,x') as a function of Z, we have

K (x₁, x') =  x²₁ x'²₁ + 2x₁x₂ x'₁ x'² + x²₂ x'²₂

Simplified, we have

(x₁ x₁¹ + x₂x¹₂)² =  Z²; and

[(a+b)² = a²+2ab+b₂] = z x₁x₁¹ + x₂x₁²

Therefore,

K (x, x¹) = Z²

Answer:

[tex]\frac{\sqrt{731}}{30}[/tex]

Step-by-step explanation:

We first observe that the angle is located in quadrant III

This allows us to draw a triangle as attached in the attachments.

Using this triangle, we can find sin([tex]\theta_1[/tex]).

Remembering that sin(theta) = [tex]\frac{opp}{hypo}[/tex], we can see from the attached image that it is [tex]\frac{\sqrt{30^2 - 13^2}}{30}[/tex], then simplifying [tex]\sqrt{30^2 - 13^2}[/tex] using a calculator, we get [tex]\sqrt{731}[/tex].

So our final answer is the answer shown above.

You may be wondering how did the side lengths appear on the triangle.

From cos(theta_1), we remember that cos(theta) = adj/hypo, so, we can draw our triangle using that the adjacent of the theta = -13 (another reason why is because the angle is in quadrant three), and hypo is 30.
