The equation of the perpendicular bisector for the line is y = 1/3(x) - 2

Given: the endpoints of the line (4,6) and (8,-6)

The bisector of the line will divide the line into two i.e. the bisector will be at the point of the line.

The coordinate of the midpoint can be calculated using the formula below:

Xm = (X1 +X2)/2  and Ym = (Y1 +Y2)/2

Where X1 = 4, Y1 =6 and X2= 8, Y2= -6

Xm = (4+8)/ 2 = 12/2 = 6  and Ym = (6+(-6))/2 = 0/2 = 0

Thus, midpoint(6, 0)

slope  = y2-y1 / x2-x1

Thus, the slope of the line segment (m₁)  = -6-6 / 8-4 = -12/4 = -3

When the two lines are perpendicular, the product of their slope is -1 i.e.

m₁ × m₂ = -1

where m₁ and m₂ represent the slope of the lines

Let the slope of the bisector be  m₂

-3 × m₂ = -1

m₂ = 1/3

Equation of perpendicular bisector with coordinate (6,0):

y - 0 = 1/3(x-6)

y = 1/3(x-6)

y = 1/3(x) - 2

Therefore, the equation for the perpendicular bisector of the line segment is y = 1/3(x) - 2

According to the solving the percent error = 11.764%

The percent error is the distinction between the estimated value and the real value in relation to the actual value. In those other words, the relative error is multiplied by 100 to calculate the percent error.

The difference between an approximate number and an exact value is measured in percent error. The bigger the percentage error, the further your estimated value deviates from the known value; conversely, the smaller the percentage error, more closer your approximation to the true value.

Actual value = 408

Expected value = 456

We know that the percent error :

= (expected value - actual value)/actual value.

= (456 - 408)/ 408

= 48/408

= 11.764

= 11.764%

SHe got a 8 on the 8th quiz

Step-by-step explanation:

The score for eighth quiz is 8.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

The average for 5 quiz marks is 8.

So, total quiz point = 8 x 5

                                = 40

Now, for next two the score are 7 and 8

The Total quiz point= 40 + 7+ 8= 55

let x be score on the 8th quiz

55+ x /8= 7.5

52 + x = (7.5)(8)

x = 60 - 52

The degree and number of unique zeros of f(x) = (x – 5)(x + 3)(x – 1)² is:

Degree: 4; number of unique zeros: 3.

The end behavior of the polynomial is:

As x → –∞, f(x) → ∞ and as x → ∞, f(x) → ∞.

The degree of the polynomial function is given by the sum of the multiplicities of the roots.

These roots are given as follows:

Hence the degree is:

1 + 1 + 2 = 4.

The unique zeros are the roots, hence there are three unique zeros, which is the same number of linear factors of the function.

The end behavior is the limit of the function as x goes to negative infinity and to positive infinite, hence:

The time that initial investment be doubles is 20 year.

What is compound interest?

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest. It is the result of reinvesting interest, or adding it to the loaned capital rather than paying it out, or requiring payment from borrower, so that interest in the next period is then earned on the principal sum plus previously accumulated interest.

Compound interest = principal (1+r/100)^n

compound interest = 3800.

3800 = 1900(1+3.5%)^n

3800/1900 = 1.035^n

taking natural log

ln(2) = n ln(1.035)

n = ln(2)/ln(1.035)

n = 20.15

Hence, time is 20 years.

The graph which represents the polynomial function f(x) = x^3 - 2x^2 - 5x + 6 is in option A.

First, let us understand the polynomial function:

A polynomial function is one that uses only non-negative integer powers or positive integer exponents of a variable in an equation such as the quadratic equation, cubic equation, and so on. For example, 9y + 6 is a polynomial with an exponent of 1.

We are given:

f(x) = x^3 - 2x^2 - 5x + 6

We know that, when the graph intersects the x-axis, it satisfies the equation that is f(x) = 0 at that point.

Let us check the points one by one;

Option A;

The graph intersects the x-axis at -2, 1, and 3 it should satisfy the equation f(x) = 0.

Let's put x = -2 in f(x), we will get;

f(-2) = -2^3 - 2(-2)^2 - 5(-2) + 6 = -8 - 8 + 10 + 6 = -16 + 16 = 0

f(-2) = 0.

Let's put x = 1 in f(x), we will get;

f(1) = 1^3 - 2(1)^2 - 5(1) + 6 = 1 - 2 - 5 + 6 = 7 - 7 = 0

f(1) = 0.

Let's put x = 3 in f(x), we will get;

f(3) = 3^3 - 2(3)^2 - 5(3) + 6 = 27 - 18 - 15 + 6 = 33 - 33 = 0

f(3) = 0.

So, the points -2, 1, and 3 satisfy the equation f(x).

Thus, the graph which represents the polynomial function f(x) = x^3 - 2x^2 - 5x + 6 is in option A.

ABCDEFGHIJ is a regular decagon. It rotates clockwise about its center to form the polygon A'B'C'D'E'F G'HIJ.

To find the each angle of rotation to the point A' coincides with after that rotation.

Now, According to the question:

let's know about Decagon:

A decagon is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°. A self-intersecting regular decagon is known as a decagram.

Every regular polygon with n sides can be divided into n  congruent triangles. The angle with vertex the center of the polygon will measure

360 : n degrees.  We are given a regular decagon, therefore:

n = 10

α = 360 : n = 36°

We consider that, if the decagon is not rotated, A' coincides with A and the rotation is towards the next letter of the alphabet. This means that after one rotation of 36° A' will coincide with B, after two rotations A' will coincide with C and so on.

A' will coincide with D after three rotations: 3 × 36° = 108°

The probability that the mean actual weight for the 100 weights is greater than 25.2 is equal to 0.0136%.

In order to determine the probability that the mean actual weight for the 100 weights is greater than 25.2, we would have to calculate the mean and standard deviation.

In a uniform distribution, the mean of a data set can be calculated by using this formula:

Mean, E(x) = [a + b]/2

Where:

Substituting the given parameters into the formula, we have;

Mean, E(x) = [24 + 26]/2

Mean, E(x) = 50/2

Mean, E(x) = 25.

For the standard deviation, we have:

Standard deviation, S(x) = √((b - a)²/12)

Standard deviation, S(x) = √((26 - 24)²/12)

Standard deviation, S(x) = √((2)²/12)

Standard deviation, S(x) = √(4/12)

Standard deviation, S(x) = 0.5774.

For the sample standard deviation, we have:

Standard deviation = S(x)/√n

Standard deviation = 0.5774/√100

Standard deviation = 0.5774/10

Standard deviation = 0.05774.

By applying the central limit theorem, we would determine the z-score as follows:

Z-score = (x - μ)/σ

Z-score = (25.2 - 25)/0.05774

Z-score = 0.2/0.05774

Z-score = 3.64

If the dairy farmer wants to mix a 80% protein. The amount of pounds of each that he should use is 80% 280 pounds and 55% 1120 pounds.

Protein I 80% = x pounds

Protein II 55% = 1400 - x pounds

Mixture 60% = 1400

Hence,

80% x + 55% ( 1400 - x ) = 60% × 1400

80 x + 55 ( 1400 - x ) = 84000

80 x + 77000 - 55 x = 84000

Combine like terms

80 x - 55 x = 84000 - -77000
