As per the Newton's method, the equal ration of the Pizza is 3: 2: 3

In math, Newton's method states that a technique for solving equations of the form f(x)=0 by successive approximation

Here we have given that three calculus students entered a pizza parlor. they were quite hungry and ordered an entire pie, instead of having the pizza maker cut the pie in the usual manner they asked her to slice the pie into three equal areas using only two parallel slices.

And we need to find these slices be made in order to accomplish this

Here let us assuming that the pizza has unit radius, and the area of the pizza is π and each piece has to have area π/3.

Therefore, the given details is enough to find the height of a circle segment such that its area is one third of the original circle,

As per the Newton's method, we get the value of h as,

=> h ≈ 0.735068 ≈ 4492/6111,

Therefore the three slices have widths approximately proportional to 3:2:3.

The instantaneous rate of change of f(x) = x³ − 5 at (2,3) is (b) 12

From the question, we have the following parameters that can be used in our computation:

Function: f(x) = x³ − 5

Point = (2, 3)

Differentiate the function to get the instantaneous rate

This is represented as

f'(x) = 3x²

Substitute 2 for x in the equation

The 2 is coming from the x-coordinate in (2, 3)

So, we have

f'(2) = 3(2)²

Answer:

6 centimeters is equal to 0.07 yards.

Step-by-step explanation:

To convert 6 centimeters into yards, we need to first convert the distance from centimeters to meters by dividing the distance in centimeters by 100:

Distance in meters = Distance in centimeters / 100

Distance in meters = 6 cm / 100

Distance in meters = 0.06 m

Next, we can convert the distance from meters to yards by dividing the distance in meters by 0.9144, which is the number of meters in a yard:

Distance in yards = Distance in meters / Meters per yard

Distance in yards = 0.06 m / 0.9144 m/yard

Distance in yards = 0.0654 yards

Rounded to the nearest hundredth, 6 centimeters is equal to 0.07 yards.

She sold more cheese boxes on Tuesday.

Comparing numbers in maths is defined as a process or method in which one can determine whether a number is smaller, greater, or equal to another number according to their values.

Given that, Marietta is selling cheeses for the holiday fundraiser. On Monday, she sold seven-ninths of the boxes of cheeses. On Tuesday, she restocked her supply and sold 0.85 of the boxes of cheeses.

On Monday = 7/9 = 0.777

On Tuesday = 0.89

Since, 0.89 > 0.777

Hence, she sold more on Tuesday.

The probability that this person has an IQ greater than 95 =62.93%

The area of mathematics known as probability is concerned with the outcomes of random events. Probability refers to a chance or potential for something to happen. It explains the likelihood that a specific event will take place.

We frequently say things like, "It will probably rain today," "He will probably pass the test, "There is very little chance of getting a storm tonight," and "Most likely the price of onions will increase once more." We substitute the word probability for all of the words chance, doubt, maybe, likely, etc. in these sentences.

In essence, probability is the ability to forecast an outcome based on the variety and quantity of potential outcomes or the analysis of historical data.

Surface area implies the external surface that bounds a given shape. The surface area of the shape is 384 sq in.

The surface area of a shape is the external side of the shape that can be seen. Sometimes, a given shape may have different shapes that forms its surface area.

From the given question,

i. The area of triangular surface = 1/2 * base* height

                          = 1/2*12*8

                          = 48

Area of the triangular surface = 48 sq in.

ii. The area of its rectangular sides = length * width

                                  = 9* 10

                                  = 90

Area of its rectangular sides = 90 sq in.

iii. The area of its base = length * width

                             = 9 * 12

                             = 108

Area of its base = 108 sq in.

Therefore,

the surface area of the shape = (2*48) + (2*90) + 108

                            = 96 + 180 + 108

                            = 384 sq in.

Answer:

To determine the percentage decrease in W when x is decreased by 9.75%, we need to first determine the relationship between w and x. Since w is proportional to the square root of x, we can write an equation to represent this relationship as follows:

w = k * √x

where k is the proportionality constant.

If the value of x is decreased by 9.75%, we can write the new value of x as follows:

x' = x * (1 - 0.0975) = x * 0.9025

Substituting this expression for x' into the equation above, we get:

w' = k * √(x * 0.9025)

To determine the percentage decrease in w, we can divide the new value of w by the original value of w and multiply by 100% to get the percentage change, or:

percentage decrease in w = (w' / w) * 100%

Substituting the expressions for w' and w into this equation, we get:

percentage decrease in w = [(k * √(x * 0.9025)) / (k * √x)] * 100%

Simplifying this expression, we get:

percentage decrease in w = (√(0.9025)) * 100%

Since the square root of 0.9025 is approximately 0.95, we can say that the percentage decrease in w is approximately 5%. This means that the value of w decreases by approximately 5% when the value of x decreases by 9.75%.

Answer:

x= 2 and x= -(2/3)

Step-by-step explanation:

Step 1 :Multiply all terms by the same value to eliminate fraction denominators

x^2/ x+6 = 1/2

2(x+6)*(x^2/x+6) = 2(x+6) * 1/2

Step 2: Cancel multiplied terms that are in the denominator

2x^2= x+6

Step 3: Move terms to the left side

2x^2 - (x+ 6) = 0

Step 4: Distribute

2x^2 - x - 6 = 0

Step 5: Use the quadratic formula

x= ( - (-1) +- Squar((-1)^2-4*2(-6)) ) / 2*2

Step 6: Simplify

x= (1+- 7)/ 4

Step7: Separate the equations

Step 8: Solve that 2 small equation

x= 2 and x= -(3/2)

Answer:

x = - [tex]\frac{3}{2}[/tex] , x = 2

Step-by-step explanation:

x² : x + 6 = 1 : 2

express the ratio in fractional form

[tex]\frac{x^2}{x+6}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2x² = x + 6 ( subtract x + 6 from both sides )

2x² - x - 6 = 0 ← in standard form

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × - 6 = - 12 and sum = - 1

the factors are - 4 and + 3

use these factors to split the x- term

2x² - 4x + 3x - 6 = 0 ( factor the first/second and third/fourth terms )

2x(x - 2) + 3(x - 2) = 0 ← factor out (x - 2) from each term

(x - 2)(2x + 3) = 0 ← in factored form

equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = - [tex]\frac{3}{2}[/tex]

The probability that the deal of a five-card hand provides a pair of aces is 0.0399

In this question, we have been given a deck of playing cards contains 52 cards, four of which are aces.

We need to find the probability that the deal of a five-card hand provides a pair of aces.

The sample space for given experiment is: choosing 52 cars choosing 5.

n(S) = 52C_5

We need to find the chance of getting a pair of aces, there are 4 aces in the pack on 2 of them.

So, n(A) = 4C_2

So that means there are 48 cards left which are not aces in the pack and want 2 of those.

So, the required probability is:

P(A) = (4C_2 * 48C_3) / 52C_5

P(A) = (6 * 17296) /2598960

P(A) = 103776 / 2598960

P(A) = 0.0399

As  shown in the figure below h is the length of the house so we have to find h .

the ladder form a right angled traingle where base of the ladder is 3 m.

and the height of wall to which ladder is leaning against is 10m. and the ladder is the longest side of the right angled traingle i.e Hypotenuse

so we wil use Pythagoras theorem to find the longest side of ladder + wall system

so for a right angled traingle Pythagoras theorem states that

[tex]h^2 = p^2 + b^2[/tex]

where h=Hypotenuse ,p=perpendicular , b=base.

so we have to find h given p= 10m ,b=3m

so putting the values of p and b in the above equation we get

[tex]h^2 = 10^2 +3^2 =109[/tex]

so

[tex]h=\sqrt{109} = 10.44 m[/tex]
