The intersection of any two perpendicular bisectors of any two triangle sides is known as the circumcenter of a triangle ABC.

The equation y=1 is the perpendicular bisector of sides B(3,0) and C(3,2). Because AB's midpoint is at 3,1 and its slope is unknown. The perpendicular bisector has zero slope. The equation for such a line is y=y1.

The equation for the perpendicular bisector of A(0,0) and B is also x=1.5 (3,0). The reason is that AB has a midpoint of zero slope and (1.5,0). The perpendicular bisector's slope won't be clearly defined. The equation for such a line is x=x1.

Life expectancy in the U.S. is steadily increasing due to medical advancements and the increased awareness of maintaining a healthy lifestyle.  0.126 x + 76.74 less-than-or-equal-to 85.  Option A

Generally,  Based on an organism's birth year, present age, and other demographic parameters like sex, life expectancy is a statistical assessment of the typical amount of time that it is predicted to live. Life expectancy at birth, which has two definitions, is the most often used metric.

This inequality states that the life expectancy of women, modeled by the function W(x), is at least 85.

The less-than-or-equal-to symbol is used because the inequality is asking for the minimum birth year required to achieve a life expectancy of at least 85, which means that the value of the function can be equal to 85 as well as greater than 85.

2 .The ratio of DE:AB is DE/AB = √((x2-x1)^2 + (y2-y1)^2) / √((x2-x1)^2 + (y2-y1)^2)

What is the Midpoint?

The midpoint of a line segment is the point that is exactly in the middle of the line segment. It is equidistant from both endpoints of the line segment. It is represented by the coordinates (x, y), where x and y are the averages of the x-coordinates and y-coordinates of the endpoints of the line segment, respectively.

1. To solve for x, we can use the midpoint formula and the fact that D is the midpoint of AC.

The midpoint formula states that the x-coordinate of the midpoint is the average of the x-coordinates of the endpoints, and the y-coordinate of the midpoint is the average of the y-coordinates of the endpoints.

let A(x1,y1) and C(x2,y2) be the coordinates of points A and C respectively

then D(x,y) is the midpoint of AC

x = (x1+x2)/2 and y = (y1+y2)/2

Since we know that AD = 28 and DC = 22, we can use the distance formula to find the coordinates of A and C.

The distance formula states that the distance between two points (x1, y1) and (x2, y2) is √((x2-x1)^2 + (y2-y1)^2)

so we have:

√((x2-x1)^2 + (y2-y1)^2) = √((x2-x1)^2 + (y2-y1)^2) =28

√((x2-x1)^2 + (y2-y1)^2) = √((x2-x1)^2 + (y2-y1)^2) =22

square both equations and we have:

(x2-x1)^2 + (y2-y1)^2 = 28^2

(x2-x1)^2 + (y2-y1)^2 = 22^2

2. To determine the ratio of DE:AB we can use the fact that E is the midpoint of BC.

let B(x1,y1) and C(x2,y2) be the coordinates of points B and C respectively

then E(x,y) is the midpoint of BC

x = (x1+x2)/2 and y = (y1+y2)/2

Since we know that BE = 8x + 3 and EC = 5x + 7.5, we can use the distance formula to find the coordinates of B and C and then find the ratio.

Hence, The ratio of DE:AB is DE/AB = √((x2-x1)^2 + (y2-y1)^2) / √((x2-x1)^2 + (y2-y1)^2)

Step-by-step explanation:

We know that, sum of the angles in a straight line are added up to 180°.

Accordingly,

[tex]x - 6 + 8x + 24 = 180[/tex]

Combine like terms.

[tex]9x + 18 =180[/tex]

Subtract 18 from both sides.

[tex]9x = 180 - 18 \\ 9x = 162[/tex]

Divide both sides by 9.

[tex]x = 18 \degree[/tex]

Answer:

x = 18

Step-by-step explanation:

The given angles are,

→ x - 6

→ 8x + 24

We generally know that,

→ Sum of angles in straight line is 180°.

Forming the equation,

→ (8x + 24) + (x - 6) = 180

Now required value of x will be,

→ (8x + 24) + (x - 6) = 180

→ 8x + 24 + x - 6 = 180

→ (8x + x) + (24 - 6) = 180

→ 9x + 18 = 180

→ 9x = 180 - 18

→ 9x = 162

→ x = 162 ÷ 9

→ [ x = 18 ]

Therefore, the value of x is 18.

To solve this equation, you would need to isolate the logarithm on one side of the equation.

What is a logarithm in simple terms?

A logarithm is the power to which a number must be increased in order to get some other number (see Section 3 of this Math Review for more about exponents) (see Section 3 of this Math Review for more about exponents). For instance, since ten raised to the power of two equals 100, the base ten logarithm of 100 is 2, or log 100 = 2.

You can start by using the property of logarithms that states that log(a*b) = log(a) + log(b).

So, you can split the left side of the equation into two logarithms: log(3x²) + log(1 + 4/3x) = log(2x²) + log(1 + 6/x)

Now, you could use the property log(a^b) = b*log(a) to simplify the equation further.

So, you will have: 2log(x) + log(1 + 4/3x) = 2log(x) + log(1 + 6/x)

Then by using log(1+x) ≈ x, you can simplify the equation further to 2log(x) + 4/3x ≈ 2log(x) + 6/x.

Now it's clear that the equation is not true and can't be solved.

To solve this problem, we can use the formula for the slope of a line: slope = (y2 - y1)/(x2 - x1).

Plugging in the given values, we get: slope = (9 - v)/(-4 - (-7)).

We can simplify this to: slope = (9 - v)/3.

Since the slope is given as 6, we can set this expression equal to 6 and solve for v:

6 = (9 - v)/3

Multiplying both sides by 3 gives us: 18 = 9 - v

Adding v to both sides gives us: 18 + v = 9

Subtracting 9 from both sides gives us: v = 9 - 18

Finally, we can simplify this to: v = -9

So the value of v is -9.

Answer:

-9

Step-by-step explanation:

(9 - v)/(-4+7)= 6

The remainder when X 3x² 2x 1 is divided by x 1 is 2, the last coefficient.

To find the remainder when dividing X 3x² 2x 1 by x 1, we can use the division algorithm. This algorithm states that the remainder is equal to the dividend minus the product of the divisor and the quotient.

To find the quotient, we can use synthetic division, which is a shortcut method that allows us to divide polynomials without needing to use the traditional long division method.

In this case, the divisor is x 1, so we write down x 1 and the coefficients of X 3x² 2x 1 in order from the highest degree to the lowest degree, which is 3x² 2x 1. We then divide the first coefficient, 3, by the divisor, 1, and write this result, 3, as the first number in the quotient.

We then multiply 3 by the divisor, 1, and subtract this from the dividend. The result of this subtraction is 3x² 2x, so we repeat this process until we reach the last coefficient, which is the remainder. In this case, the last coefficient is 2, so this is the remainder when dividing X 3x² 2x 1 by x 1. Therefore, the remainder is 2.

Iterations are required to sort the array 10 23 14 35 17 15 16 using selection sort = 5

The selection sort algorithm sorts an array by repeatedly finding the minimum element (considering ascending order) from the unsorted part and putting it at the beginning.

The algorithm maintains two subarrays in a given array.

The subarray which already sorted.

The remaining subarray was unsorted.

In every iteration of the selection sort, the minimum element (considering ascending order) from the unsorted subarray is picked and moved to the beginning of unsorted subarray.

After every iteration sorted subarray size increase by one and unsorted subarray size decrease by one.

After N (size of array) iteration we will get sorted array.

Lets consider the following array as an example: array[] ={10 23 14 35 17 15 16}

{64, 25, 12, 22, 11}

First pass:

For the first position in the sorted array, the whole array is traversed from index 0 to 6 sequentially. The first position where 10 is stored presently, after traversing whole array it is clear that 10 is the lowest value.

  10      23       14      35       17      15         16

Thus, replace10 with 10. After one iteration 10, which happens to be the least value in the array, tends to appear in the first position of the sorted list.

10      23       14      35       17      15         16

Second Pass:

For the second position, where 23 is present, again traverse the rest of the array in a sequential manner.

 10      23       14      35       17      15         16

After traversing, we found that 14 is the second lowest value in the array and it should appear at the second place in the array, thus swap these values.

  10      14       23      35       17      15         16

Third Pass:

Now, for third place, where 23 is present again traverse the rest of the array and find the third least value present in the array.

  10      14       23      35       17      15         16

While traversing, 15 came out to be the third least value and it should appear at the third place in the array, thus swap 15 with element present at third position.

   10      14       15      35       17      23         16

Fourth pass:

Now, for fourth place, where 35 is present again traverse the rest of the array and find the fourth least value present in the array.

 10      14       15      35       17      23         16

While traversing, 16 came out to be the fourth least value and it should appear at the fourth place in the array, thus swap 16 with element present at fourth position.

10      14       15      16       17      23         35

Fifth Pass:

At last the largest value present in the array automatically get placed at the last position in the array
