The midpoint of a line segment is the point equidistant to the endpoints of the line. The coordinate of S is (2,-9)

Given that:

\(T(x_1,y_1) = (0,5)\)

\(M = (1,-2)\) --- the midpoint of ST

\(S = (x_2,y_2)\)

To calculate the coordinates of S, we use the following midpoint formula:

\(M = 0.5 \times (x_1 + x_2,y_1+y_2)\)

So, we have:

\((1,-2) = 0.5 \times (0 +x_2,5 + y_2)\)

Divide both sides by 0.5

\((2,-4) = (0 +x_2,5 + y_2)\)

\((2,-4) = (x_2,5 + y_2)\)

Compare both sides

\(x_2 = 2\)

\(5 + y_2 = -4\)

Collect like terms

\(y_2 = -4-5\)

\(y_2 = -9\)

Hence, the coordinates of S is:

\(S = (2,-9)\)

Answer:

535,095 different samples of size six that contain exactly 2 defective parts.

0.0337 = 3.37% probability that a sample contains exactly 2 defective parts.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

As the order of the parts is not important, the combinations formula is used to solve this question.

Combinations formula:

\(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

How many different samples are there of size six that contain exactly 2 defective parts?

2 defective from a set of 3, and 4 non-defective from a set of 47. So

\(D = C_{3,2}*C_{47,4} = \frac{3!}{2!1!}*\frac{47!}{4!43!} = 535095\)

535,095 different samples of size six that contain exactly 2 defective parts.

What is the probability that a sample contains exactly 2 defective parts?

The total number of samples is:

\(T = C_{50,6} = \frac{50!}{6!44!} = 15890700\)

Then...

\(p = \frac{D}{T} = \frac{535095}{15890700} = 0.0337\)

0.0337 = 3.37% probability that a sample contains exactly 2 defective parts.

Answer:

all real values of x where x < -1

The correct statement is all real values of x where x < -1.

Option A is the correct answer.

We have,

To determine the values for which the graph of the function

f(x) = (x - 3)(x + 1) is positive and decreasing, we need to analyze the behavior of the function.

Let's consider the factors individually:

(x - 3): This factor is positive for x > 3 and negative for x < 3.

(x + 1): This factor is positive for x > -1 and negative for x < -1.

To determine the overall sign of the function, we need to consider the signs of both factors together.

When both factors are positive or both factors are negative, the function is positive.

When the factors have opposite signs, the function is negative.

From the above analysis, we can conclude the following:

When x > 3, both factors are positive, so the function is positive.

When -1 < x < 3, the factor (x - 3) is negative, while the factor (x + 1) is positive. Therefore, the function is negative.

When x < -1, both factors are negative, so the function is positive again.

Since we are looking for values where the function is positive and decreasing, we can eliminate the options that include positive and increasing regions (such as x > 3).

Thus,

The correct statement is all real values of x where x < -1.

Therefore, the answers for the given composite functions are:

f(g(7)) = 814

g(f(4)) = 151

f(g(8)) = 898

f(f(2)) = -4

A function from a set X to a set Y allocates precisely one element of Y to each element of X. The set X is known as the function's domain, while the set Y is known as the function's codomain. Originally, functions were the idealization of how a variable quantity depended on another quantity.

Here,

To evaluate function compositions, we substitute the inner function into the outer function and simplify.

(a) To evaluate f(g(7)), we first find g(7):

g(7) = 7(7)^2 + 9(7) + 3 = 343 + 63 + 3 = 409

Now we can substitute g(7) into f(x):

f(g(7)) = f(409) = 2(409) - 4 = 814

(b) To evaluate g(f(4)), we first find f(4):

f(4) = 2(4) - 4 = 4

Now we can substitute f(4) into g(x):

g(f(4)) = g(4) = 7(4)^2 + 9(4) + 3 = 112 + 36 + 3 = 151

(c) To evaluate f(g(8)), we first find g(8):

g(8) = 7(8)^2 + 9(8) + 3 = 7(64) + 72 + 3 = 451

Now we can substitute g(8) into f(x):

f(g(8)) = f(451) = 2(451) - 4 = 898

(d) To evaluate f(f(2)), we first find f(2):

Answer:

the value of a - b is 4.

Step-by-step explanation:

We have been given the following two equations:

a + b = 10 ------------(1)

a² - b² = 40 -------(2)

We can factor the left-hand side of equation (2) using the difference of squares identity:

(a + b)(a - b) = 40

Substituting equation (1) into this equation, we get:

10(a - b) = 40

Dividing both sides by 10, we get:

a - b = 4

Therefore, the value of a - b is 4.

Step-by-step explanation:

if I understand this correctly :

a + b = 10

a² - b² = 40

(a² - b²) = (a + b)(a - b) = 40

10(a - b) = 40

(a - b) = 4

The question is the base of the triangle, so we use the formula : b²=c²–a²

——————————————————————

\( {b}^{2} = \sqrt{c^{2} - {a}^{2} }\)

\( {b}^{2} = \sqrt{ {16}^{2} - {8}^{2} } \)

\( {b}^{2} = \sqrt{256 - 64} = \sqrt{192} \)

Answer:  y=-(4/3)*x-6

Step-by-step explanation:

The equation of any straight line is y=a*x+b  (1).

So we have to find the coefficients a and b and substitute them to the equation (1).

If the required line is perpendicular to y= (3/4)*x-2 it means that

a= -(4/3)   (we have to inverse the fraction 3/4 and put the opposite sign after that.  3/4 has the sign + in front of it  so we have to put sign -)

So the equation of required line is y= -(4/3) *x+b .

Now we have to find b.   To do that pls remember that the point (-12;10)  belongs to the required line y= -(4/3) *x+b  . That means:

10=-(4/3)*(-12)+b  => 10=16+b =>  b=-6

So substitute b in equation (1) and get:

y=-(4/3)*x-6

Item price now= 3.95

Step-by-step explanation:

To find out the price now, we will subtract 79 (original price) by 95% of 75. That will equal the discounted price. Finding the percentage of anything, we can use the formula, Total amount•percentage/100. The total amount is 79, and the percentage is 95. 79•95=7505, 7505/100=75.05. Now, 95% of 79 is 75.05, 79-75.05=3.95. $3.95 is the price now of the item. Though, I am unsure what a ALEKS calculator is. Have a nuce time, and joyful day

Answer:

Both Pitchers

Step-by-step explanation:

First, we determine how many of each pitcher it would take to fill the 300 liter and 180 liter containers.

300÷15=20 of the 15 liter pitcher

300÷20=15 of the 20 liter pitcher

Similarly

180÷15=12 of the 15 liter pitcher.

180÷20=9 of the 20 liter pitcher.

The two pitchers gives a whole number when their volumes divide the volumes of the containers.

Therefore, the two pitchers exactly fill the containers without milk being left over.

Answer:

x=53

Step-by-step explanation:

One way to solve this problem is by using the Pythagorean Theorem.

This states that the square of one "leg" of the triangle plus the square of the other "leg" of the triangle would equal the square of the hypotenuse,  or the longest side of a triangle. Keep in mind that this only works for right triangles, where one angle  is exactly 90 degrees.

This formula can be written as: a^2 + b^2 =  c^2, where a and b are the legs and c is the hypotenuse.

So, for this problem, let a=28, and b=45.

This gives us: 28^2 + 45^2 = x^2

And we can simplify this to: 2809 = x^2

Taking the square root of both sides gives us the answer,  that x=53 units.

Hence, compared to the second plant, the first plant produces \(3x + 14\)more things per day.

Production is the process of creating goods or services that can be used or consumed by individuals or other entities. It involves converting raw materials, labor, and capital into finished products or services that are suitable for sale or distribution in the market.

given

We must take the daily production of the second plant away from the daily production of the first plant in order to calculate how many more things are produced daily by the first plant than the second plant.

The first plant's daily output is equal to \(5x + 11.\)

Daily output of the second plant is equal to \(2x - 3.\)

As a result, the two facilities' daily production differences are as follows:

\((5x + 11) - (2x - 3) = 5x + 11 - 2x + 3\)

According to the information, the perimeter of the triangle is ≈ 31.18

To find the distance between two points, we can use the distance formula:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Let's label the coordinates as follows:

Point 1: (-2, 3)

Point 2: (3, -2)

Now we can substitute these values into the distance formula:

distance = sqrt((3 - (-2))^2 + (-2 - 3)^2)

distance = sqrt((5)^2 + (-5)^2)

distance = sqrt(25 + 25)

distance = sqrt(50)

distance ≈ 7.07

Therefore, the distance from (-2, 3) to (3, -2) is approximately 7.07 units.

To find the perimeter of the triangle, we need to find the length of all three sides of the triangle and then add them up.

Using the distance formula, we can find the length of the sides:

Side 1: (-2,3) to (3,-2)

d = √[(3 - (-2))^2 + (-2 - 3)^2]

= √[5^2 + (-5)^2]

= √50

= 5√2

Side 2: (3,-2) to (-7,-2)

d = √[(-7 - 3)^2 + (-2 - (-2))^2]

= √[(-10)^2 + 0^2]

= 10

Side 3: (-7,-2) to (-2,3)

d = √[(-2 - (-7))^2 + (3 - (-2))^2]

= √[5^2 + 5^2]

= 5√2

Therefore, the perimeter of the triangle is:

5√2 + 10 + 5√2 = 15√2 + 10 ≈ 31.18 (rounded to two decimal places)

An two of the three sides are equal, so it is an isosceles triangle.
