Why does 0.5x0.11 is equal to 0.055

According to the angle of incidence, the angle of reflection will also be 36°

Angle of incidence:

In math it means the angle which an incident line or ray makes with a perpendicular to the surface at the point of incidence.

Given,

Here we need to find the If light strikes a plate mirror at a 36° angle of incidence, then what would you expect the resulting angle of reflection to be.

Here we know that, the incident ray, the reflected ray and the normal ray at the point of incidence all lies in the same plane.

Then the angle of incidence is equal to the angle of reflection

And it can be written as,

=> Angle of incidence = angle of reflection

As per the 2nd law given above, we say that if a light ray incident at 45°, then the reflected angle will also be 45°

Here we know that the value of,

=> Angle of incidence = 36°

Therefore, the Angle of reflection = 36°

An equation is a formula that expresses the equality of  expressions, with the aid of using connecting them with the equals signal =. The value of x in the equation 8/3x + 1/3x = 3 1/3 + 7/3x is x = 1.

The required details for equation in given paragraph

The word equation and its cognates in different languages can also additionally have subtly extraordinary meanings; for example, in French an equation is described as containing one or more variables, whilst in English, any well-shaped formula which includes expressions associated with an equals signal is an equation. Solving an equation containing variables includes figuring out which values of the variables make the equality true. The variables for which the equation must be solved also are called unknowns, and the values of the unknowns that fulfill the equality are called solutions of the equation.

To find the value of x in the equation 8/3x + 1/3x = 3 1/3 + 7/3x, we need to first get all of the terms with x on the same side of the equation.

We can start by moving the 3 1/3 to the right side of the equation by subtracting it from both sides:

8/3x + 1/3x - 3 1/3 = 7/3x - 3 1/3

Next, we can combine the coefficients of x on the left side of the equation:

(8/3 + 1/3) x = (7/3 - 3 1/3)

4/3 x = 4/3

Finally, we can divide both sides of the equation by 4/3 to find the value of x:

(4/3) x / (4/3) = (4/3) / (4/3)

x = 1

Therefore, The value of x in the equation 8/3x + 1/3x = 3 1/3 + 7/3x is x = 1.

According to Hooke's law, a material's strain will increase in direct proportion to its applied stress up to its elastic limit. When elastic materials are stretched, atoms and molecules deform up to a point of stress, after which they return to their original shape.

Hooke's law only approximates in first-order linear terms how springs and other elastic bodies actually react to applied forces. Since no material can be stretched or squeezed beyond a given size without permanently deforming or changing its condition, it must inevitably fail once the forces reach a certain threshold.

Many substances will diverge from Hooke's law clearly before they reach such elastic limits.

On the other hand, as long as the forces and deformations are small enough, Hooke's law provides a close approximation for the majority of solid bodies. Since it is the basis of many fields including seismology, molecular mechanics, and acoustics,

Hooke's law is widely applied in all branches of science and engineering. It.

Hence, a material's strain will increase in direct proportion to its applied stress up to its elastic limit. When elastic materials are stretched, atoms and molecules deform up to a point of stress, after which they return to their original shape.

The inequality on the graph is a linear inequality, and it can be written as:

y > 2x - 4

On the graph, we can see a linear inequality, we can see a dashed line with a positive slope, and the shaded area is above that line, so the inequality is of the form:

y > line.

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through two points (x1, y1) and (x2, y2), then the slope is:

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

We can find two points on the graph, we can see that the line passes through (0, -4) and (2, 0), then the y-intercept is -4 and the slope is:

Square is a polygon which has 4 sides. All four sides of square are equal length and perpendicular to each other that means the angle between two adjacent side is 90°.

Given that ABCD is a square surface. And diagonal of square creates two isosceles triangles.

So the ∠ABC = ∠BCD = ∠CDA = DAB = 90°

Here, BD and AC are two diagonals of a square ABCD and E is the intersection point of diagonals.

Diagonals cut each other perpendicular.

So, ∠AED = 90°  and ∠EAD = ∠EDA = 45°

Now to find ∠BAC;

we have ∠ABC = 90° so from the property of isosceles triangle

∠BAC = ∠BCA = 45°

In isosceles triangle BCD,

∠BCD = 90° and ∠DBC = ∠BDC = 45°

What is a percentage?

A relative value indicates the hundredth part of any quantity. One percent (symbolized 1%) is the hundredth part; thus, 100 percent represents the entirety and 200 percent specifies twice the given quantity.

To compare the two options and determine which one will result in you making more money, we need to find the total amount of money you will make under each option.

Under option A, you will receive a $6,000 raise in year 1 and a 4% raise in year 2. Let's call your base salary S. After the first year, your salary will be S + $6,000. After the second year, your salary will be (S + $6,000) * 1.04 = S + $6,240.

Under option B, you will receive a 4% raise in year 1 and a $6,000 raise in year 2. After the first year, your salary will be S * 1.04 = S + $480. After the second year, your salary will be (S + $480) + $6,000 = S + $6,480.

Comparing the two options, we see that under option B, you will make more money than under option A. This is because option B includes a $6,000 raise in the second year, while option A includes a smaller 4% raise in the second year.

Using the absolute value and PEMDAS order of operations, it is found that:

a) The missing expression for step 2 is: (36 + 2)/0.5 = − 14.8 ÷ 8.

b) The missing expression for step 6 is 76 - 1.85.

The absolute function is defined by:

|x| = x, x ≥ 0.

|x| = -x, x < 0.

Thus, it usually measures the distance of a point x to the origin, hence |0.5| = |-0.5| = 0.5

In Step 2, we just have to apply the absolute value property to |-0.5|, and as such, the missing expression for step 2 is:

(36 + 2)/0.5 = − 14.8 ÷ 8.

The slope of the line y = 14x – 1 is 14.

To find the slope of a line, we need to know two points on the line. We can choose any two points, as long as they are not the same. For example, we can choose the points (0, -1) and (1, 13):

y = 14x – 1

y = 14(0) – 1 = -1 when x = 0

y = 14(1) – 1 = 13 when x = 1

The slope of the line is the change in y divided by the change in x between these two points. In this case, the change in y is 13 – (-1) = 14, and the change in x is 1 – 0 = 1. Therefore, the slope of the line is 14/1 = 14.

We can also write the slope as a simplified fraction. In this case, 14 is already a simplified fraction, so we don't need to simplify further. Therefore, the slope of the line y = 14x – 1 is 14.

Answer:

A.) [tex]\frac{1}{5^6}[/tex]

Step-by-step explanation:

To simplify [tex](5^2)^3[/tex], use the exponent rule that states [tex](a^m)^n=a^{mn}[/tex]

So,

[tex](5^2)^3=5^{2*3}=5^6[/tex]

Use the same exponent rule to begin simplifying [tex](5^4)^{-3}[/tex]:

[tex](5^4)^{-3}=5^{4*(-3)}=5^{-12}[/tex]

To further simplify [tex]5^{-12}[/tex], use the exponent rule that states [tex]a^{-m}=\frac{1}{a^m}[/tex]

So,

[tex]5^{-12}=\frac{1}{5^{12}}[/tex]

Then multiply the two new expressions as indicated in the original problem:

[tex](5^6)(\frac{1}{5^{12}})=\frac{5^6}{5^12}=\frac{1}{5^6}[/tex]

Alternatively, you could use the exponent rule that states [tex]a^m*a^n=a^{m+n}[/tex]

where

[tex]a^m=5^6\\a^n=5^{-12}[/tex]

A line's angle of slope between two points is (5, -4)

A line's angle of slope between two points is given as follows:

m = y2-y1/x2 - x1

A line passing through a given point and having the following equation:

y - y₁ = m(x - x₁)

Line A:

m = -1 - 5 /3- (-1) = -6 /4 = -3/2

y - 5 = -3 / 2(x +1)

y = -3/2 (x + 1) + 5.

Line B:

m = -1-2/6-7  = -3 / -1 = 3

y - 2 = 3 (x - 7)

y = 3(x -7) + 2.

Point of intersection denotes identical x and y coordinates.

So:

3(x - 7)+ 2 = -3/2 (x + 1 ) +5

3x - 21 + 2 = -3/2x - 3/2 +5

3x - 19 = -3/2x + 7/2

6x - 38 = 3x +7

6x + 3x = 7 + 38

9x =45

x = 5

y = 3(5 - 7) + 2 = 3(-2) + 2 = -4.
