The line of reflection for this problem is defined as follows:

x = -1.

The line of reflection is drawn on the image given at the end of the answer.

How to obtain the line of reflection?

The vertices of the two triangles have the same y-coordinates, while the x-coordinates are different, hence the reflection line is a vertical line.

The x-coordinates will be equidistant to the reflection line, just on opposite coordinates.

Considering that the reflection changes the "faces" of the triangles, D and E are equivalent vertices, thus the reflection line is given by the mean of the x-coordinates of these two points, hence:

x = (-3 + 1)/2

x = -1.

What is the corresponding point on the unit circle for the given radian measure?
0=5pi/3

Answers

The corresponding point on the unit circle for the angle θ = 5pi/3  is given by: (0,5, -0.866).

What is the unit circle?

Basically, the unit circle is a circle with a radius of 1. It is used in trigonometry to help define and understand angles and their associated trigonometric values. The unit circle is centered at the origin (0, 0) of the coordinate plane, and each point on the circle is defined by its distance from the origin and its angle from the positive x-axis.

What is area of circle ?

The area of circle can be defined as the product of pi and square of radius of a given circle.

In this problem, we have that θ = 5pi/3 , hence:

cos θ = 0.5

sin θ = -0.866

Thus the point is (0,5, -0.866).

If a: b = 1:2 and b; c = 3:4, find a : c.​

Answers

Answer:

Step-by-step explanation:

b:c= 3:6

Answer:

Step-by-step explanation:

We know that:
a : b = 1 : 2 (or a = (1/b)*b)
b : c = 3 : 4 (or b = (3/4)*c)

So, we can substitute the value of b from the second equation into the first equation to get the ratio of a : c:

a = (1/b)*b = (1/((3/4)c))((3/4)c) = (4/3)(1/c)*c = (4/3)*1 = 4/3

So, the ratio of a : c is 4 : 3.

Alternatively, we can use the cross-multiplication method to find the ratio.

a : b = 1 : 2, and b : c = 3 : 4

so a4 = b3, and b4 = c3

so a4 = c3

so a:c = 3:4

In this way also we got the ratio of a:c as 3:4

145 52
290 104
435 156
580
725

Answers

Step-by-step explanation:

since a ratio is a fraction with all calculation and comparison rules (but with a special overall meaning), we need to observe the main rule for transforming fractions : when multiplying one part of the fraction by a factor, we also need to multiply the other part by the same factor to keep the value of the fraction unchanged.

the basic ratio is here

145/52 (or written 145:52 - it has the same meaning)

290/104 is just (145×2)/(52×2)

435/156 is just (145×3)/(52×3)

to complete the table we simply have to keep following that structure :

580 = 145×4

so, 52×4 = 208

and the ratio is

580/208

725 = 145×5

52×5 = 260

and the ratio is

725/260

How do you know if a function has an inverse that is also a function?.

Answers

If and only if a function is a bijective function, it has an inverse that is also a function.

Only in the condition, if a function is bijective, meaning it is both onto (surjective) and one-to-one (injective), it has an inverse that is itself a function. If there are no two random input values resulting in a similar output value, then the function is said to be injective. As a result, there is only one x-value that can yield a given y-value.

A unique inverse function cannot be determined for a function if it is not injective. Whereas, a function is surjective if at least one input value is required to produce each output value. As a result, there is at least a single x-value in the domain of the function that yields each y-value in the function's range. A function's inverse would not be defined for values in the range if it were not surjective.

What is inverse of a number?.

Answers

In common inverse meaning is “something that is contrary or reverses”. When we define inverse meaning we will talk mostly from the mathematics point of view where we find the inverse of different operations and functions

The inverse of a given number is equal to number that is obtained by solving the operation 1/x where x is the initial number.

The inverse operation of subtraction is addition, the inverse operation of division is multiplication.

The inverse of a number should not be muddled with its opposite. While the inverse is 1/x, the opposite is equal to -x. That is, the inverse of 3 is equal to 1/3 while its opposite will be equal to -3.

What is the solution of equation?

Finding an equation's solutions, which are values (numbers, functions, sets, etc.) that satisfy the equation's condition and typically consist of two expressions connected by an equals sign, is known as solving an equation in mathematics.

One or more variables are designated as unknowns when looking for a solution. An assignment of values to the unknown variables that establishes the equality in the equation is referred to as a solution.

To put it another way, a solution is a value or set of values (one for each unknown) that, when used to replace the unknowns, cause the equation to equal itself. The term "equation's root" is frequently used to refer to an equation's solution, especially but not exclusively for polynomial equations.

Given to prove b = 6

a. 8b = 48

   b = 48/8

   b = 6

b = 6 is a solution

b. 4 = b + 11 - 3b

   3b - b = 11 - 4

   2b = 7

   b = 7/2

   b = 3.5

b = 6 is a not solution

c. b + 3 = 9

   b = 9 - 3

   b = 6

b = 6 is a solution

Answers

If 60 adults ages 18-29 made resolutions, and 10% of adults are ages 18-29, we can infer that 600 people were surveyed.

How to calculate percentages?

Percentages are a way to express a number as a fraction of 100. To calculate a percentage, you can use the following formula:

(Part/Whole) x 100 = Percentage

The question states that 60 adults ages 18-29 made resolutions, but does not provide information about the total number of people surveyed. In order to determine the total number of people surveyed, we would need additional information about the percentage of adults that fall within the age range of 18-29.

If the percentage of adults ages 18-29 is 10%, and 60 adults in that age range made resolutions, we can use that information to determine the total number of people surveyed.

We can use the following formula:

(Total number of people surveyed) = (Number of adults ages 18-29 who made resolutions) / (Percentage of adults ages 18-29)

(Total number of people surveyed) = (60) / (0.10) = 600

Hence. If 60 adults ages 18-29 made resolutions, and 10% of adults are ages 18-29, we can infer that 600 people were surveyed.

The sum of the first four terms of an arithmetic progression is 14.  If the sum of the first eight terms is 108, find the sixth term of this progression.​

Answers

The sixth term of the arithmetic progression is 94.

An arithmetic progression is a sequence of numbers such that the difference between any two successive members of the sequence is a constant.

Let's call the first term of the arithmetic progression "a" and the common difference "d". Then the nth term of the progression can be found using the formula:

an = a + (n-1)d

We know that the sum of the first four terms is 14, so we can set up the following equation:

a + (a+d) + (a+2d) + (a+3d) = 14

We also know that the sum of the first eight terms is 108, so we can set up another equation:

a + (a+d) + (a+2d) + (a+3d) + (a+4d) + (a+5d) + (a+6d) + (a+7d) = 108

Now we can use the first equation to substitute for the first four terms of the second equation:

14 + (a+4d) + (a+5d) + (a+6d) + (a+7d) = 108

This gives us:

a + 4d = 94

So the sixth term can be found by substituting n = 6 into the first formula:

a + (6-1)d = a + 5d = 94

Therefore, the sixth term of the arithmetic progression is 94.
