Form the given five quadratics , the one representing the repeated roots is equal to option d. 25x² - 30x + 9 and repeated roots are 3/5 or 3/5.

Quadratics representing repeated roots has discriminant equals to zero.

Standard quadratic equation is:

ax² + bx + c = 0

Discriminant 'D' = b² - 4ac

option a. -x²+ 18x + 81

Discriminant

'D' = 18² - 4(-1)(81)

      = 324 + 324

      = 648

D>0 has distinct roots.

option b. 3x²- 3x - 168

Discriminant

'D' = (-3)² - 4(-3)(-168)

      = 9 - 2016

      = -2007

D< 0 has distinct roots.

option c. x²- 4x -  4

Discriminant

'D' = (-4)² - 4(1)(-4)

      = 16 + 16

      = 32

D>0 has distinct roots.

option d. 25x²- 30x + 9

Discriminant

'D' = (-30)² - 4(25)(9)

      = 900 - 900

      = 0

D = 0 has repeated roots.

Repeated roots are:

x = ( -b ±√D ) / 2a

  = [-(-30)±√0 ]/ 2(25)

  = 30/ 50

  = 3/5.

option e.  x² - 14x + 24

Discriminant

'D' = (-14)² - 4(1)(24)

      = 196 - 96

      = 100

D>0 has distinct roots.

Therefore, the quadratics which represents the repeated roots are given by option d. 25x² - 30x + 9 and its repeated roots are 3/5 or 3/5.

The above question is incomplete, the complete question is:

The expression 16t-3t is not equivalent to 3t-16t because the negative sign belongs to the term 3t

For t = 2, 16t - 3t is equal to 26 and 3t - 16t is equal to -26

We know that an expression is nothing but a mathematical sentence with a minimum of two numbers or variables and at least one algebraic operation.

Also,  if two expressions are equivalent expression , then the two expressions must have the same value when we substitute the same values for the variables.

Here we have been given two mathemtical expressions:

16t - 3t and 3t - 16t

For t = 2,

16(2) - 3(2)

= 32 - 6

= 26

and 3(2) - 16(2)

= 6 - 32

= -26

This means, 16t - 3t ≠ 3t - 16t

We can oberve that 16t - 3t = -(-16 + 3t)

= -(3t - 16)

This means, 16t-3t is not equivalent to 3t-16t because the negative sign belongs to the term 3t

2. look at the Y axis markings, first one goes from 5 to 11, it increased by 6.  so it's not right.

answer is the 3rd one.

Part A) According to the the scatter plot r = 0.01 is not an accurate value for this data

Part B) We have to describe a scenery where a variable is the cause of the number of strawberries picked.

The term scatter plot in math is known as  a horizontal and a vertical axis in the attempt to show how much one variable is affected by another

As we all know that the correlation coefficients r and it measure the strength of the correlation of two variables and they can have values from - 1 to  1.

Here we have know that r = - 1 is  a perfect negative correlation and the points will adjust perfectly to a line with negative slope.

Where as r =  + 1 is a perfect positive correlation and the points will adjust perfectly to a line with positive slope.

Where as r = 0 means that the variables are not correlated at all.

Hence the calculated value of r = 0.01 is not accurate for t his scatter plot.

As we all know that the causal relationship means that the explanatory variable is the cause of the dependent variable.

Therefore here we know we have to find a reasonable variable that can be the cause of the number of strawberries picked.

As the amount of rainfall is the cause of the number of strawberries picked, and you could find a model that relates both variables.

The radical expression completely:

Square root of [tex]48x^2y^5z[/tex] is  4[tex]xy^2[/tex] × sqrt(3y)

Now, According to the question:

Factor 48 into its prime factors

          48 = 24 × 3

To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.

Factors which will be extracted are :

          16 = [tex]2^4[/tex]

Factors which will remain inside the root are :

          3 = 3

To complete this part of the simplification we take the square root of the factors which are to be extracted. We do this by dividing their exponents by 2 :

          4 = [tex]2^2[/tex]

At the end of this step the partly simplified SQRT looks like this:

        4 × sqrt[tex](3x^2y^5)[/tex]z

Rules for simplifying variables which may be raised to a power:

  (1) variables with no exponent stay inside the radical

  (2) variables raised to power 1 or (-1) stay inside the radical

  (3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:

    (3.1) sqrt[tex](x^8)=x^4[/tex]

    (3.2) sqrt(x-6)=x-3

(4) variables raised to an odd exponent which is  >2  or < (-2) , examples:

     (4.1)[tex]sqrt(x^5)=x^2sqrt(x)[/tex]

    (4.2) sqrt(x-7)=x-3sqrt(x-1)

Applying these rules to our case we find out that

    SQRT[tex](x^2y^5) = xy^2[/tex]SQRT(y)

Simplified root:

4[tex]xy^2[/tex] × sqrt(3y)

As per the unitary method,

(a) The amount earned by the sales​ rep's orders in​ May is $42 600

(b) The amount did her orders​ decrease is $8520

in math the term unitary method is known as the process of how to find the value of a unit from the value of a multiple and the value of a multiple from the value of a unit.

Here we have given that a sales representative’s orders for May were 16 2/3% less than her April orders, which amounted to $51 120.

By using the unitary method as we all know that the May order is decreased, then it can be calculated as,

=> 51120 – 16 2/3% of $51120

When we simplify this one then we get,

=> 51120 – 1/6 × 51120 = 51120 – 8520

Therefore the earning is $42 600

Similarly, through the calculation we have identified that  the decreased amount is $8520.

Answer: Since AFGH is a triangle, the sum of the lengths of any two sides must be greater than the length of the third side. We can use this property, known as the triangle inequality theorem, to determine the angles of AFGH in order from largest to smallest.

We are given that the perimeter of AFGH is 87, so we know that:

FG + GH + FH = 87

6x + 7 + 8x - 5 + 10x - 11 = 87

24x + 1 = 87

24x = 86

x = 3.5

Now that we know that x = 3.5, we can use the given lengths of the sides to find the values of the sides:

FG = 6x + 7 = 6(3.5) + 7 = 23

GH = 8x - 5 = 8(3.5) - 5 = 25

FH = 10x - 11 = 10(3.5) - 11 = 29

We can now use these values to determine the angles of AFGH in order from largest to smallest.

We can use the triangle inequality theorem to determine that:

FH>FG+GH

29>23+25

Therefore, the angle that is opposite to side FH is the largest angle in the triangle, and the angles opposite to FG and GH are the smaller angles.

So, the angles in the triangle AFGH are ordered from largest to smallest:

The angle opposite to side FH, angle A, is the largest.

The angles opposite to side FG and GH are the smaller angles.

What is the slope-intercept form?

The slope-intercept form of a linear equation is y = mx + b, where x and y are variables, m is the slope of the line (also known as the "rate of change" or "rise over run"), and b is the y-intercept (the point where the line crosses the y-axis). The slope-intercept form is so called because it gives the slope of the line and the y-intercept in one equation

Here is the table you requested:

Quantity (x) Price (y)

12                  $60

This table shows the relationship between the quantity of pizzas ordered (x) and the price (y) for a pizza company that charges $60 for 12 pizzas. The equation y = mx + b can be used to represent the relationship, where m is the unit price and b is the y-intercept. In this case, m = 5 and b = 0.

Book 2 with 4 kg weight has the higher gravitational pull and the  pull decreases with increase in distance.

In Physics, the gravitational force is one of the types of forces. It is a force that attracts any two objects with mass. The gravitational force is also known as the attractive force, as it always pulls the masses of two objects together. Newton’s gravitational law states that every object in the universe is pulled by other objects. The other types of forces are electromagnetic force, strong force, weak force, and so on. The formula to calculate the gravitational force is given by Gravitational Force = (Gravitational Constant × Mass of first object × Mass of the second object) / (Distance between the centre of two bodies)².

Given here:

Book 1 has 2 kg textbook and Book 2 weighs 4 kg.

In the first case The gravitational pull when they were 2 cm apart is

F₁=    Gm₁m₂  / 2cm

  =0.00000133486 N

While if the two books are 8 cm apart we have

F₂= Gm₁m₂  / 8

  =0.0000000834288 N

clearly the gravitational pull decreases with the increase in distance.

And owing to Book 2's higher weight it has the superior gravitational pull.

The probability of drawing a white chip first and a blue chip second is 1/5.

To find the probability of drawing a white chip first and a blue chip second, we can use the formula for conditional probability.

Conditional probability is the probability of an event occurring given that another event has already occurred. It is represented by the notation P(A|B), where A is the event of interest and B is the event that has already occurred.

The formula for conditional probability is:

P(A|B) = P(A and B) / P(B)

This formula expresses the probability of event A occurring given that event B has occurred, as a ratio of the probability of the two events occurring together and the probability of event B occurring alone.

Where A is the event of drawing a white chip first and B is the event of drawing a blue chip second.

We know that the probability of drawing a white chip first is 3/10 (since there are 3 white chips out of a total of 10 chips in the bowl), so P(A) = 3/10.

Once a white chip has been drawn, there are 9 chips left in the bowl, with 6 of them being blue. This means that the probability of drawing a blue chip second given that a white chip has already been drawn is 6/9, so P(B|A) = 6/9.

By multiplying these two probabilities together, we get:

P(A and B) = (3/10) * (6/9) = (3/10) * (2/3) = 6/30 = 1/5

Therefore, the probability of drawing a white chip first and a blue chip second is 1/5.
