The answer of the given question based on the , check and revise strategy to solve the equation 1 1/4b = 8 3/4 the answer is given below,

A expression is  combination of symbols and/or numbers that represents  mathematical quantity or relationship. It can consist of variables, constants, operators, and functions, and may include arithmetic operations like addition, subtraction, multiplication, and division, as well as exponents, radicals, and other mathematical concepts.

Using guess, check, and revise strategy, we can guess a value for b, the number of batches, and check if it satisfies the given equation. If it doesn't, we revise our guess and check again until we find a solution that works.

Let's start with a guess of b = 5. Substituting b = 5 into the equation 1 1/4b = 8 3/4, we get:

1 1/4(5) = 6 1/4

Since 6 1/4 cups of chocolate chips are needed for five batches of muffins, and Manuel has only 8 3/4 cups of chocolate chips, this guess is too high. We need to revise our guess to a lower number of batches.

Let's try b = 4. Substituting b = 4 into the equation 1 1/4b = 8 3/4, we get:

1 1/4(4) = 5

Since 5 cups of chocolate chips are needed for four batches of muffins, and Manuel has 8 3/4 cups of chocolate chips, this guess is too low. We need to revise our guess to a higher number of batches.

Let's try b = 4.5. Substituting b = 4.5 into the equation 1 1/4b = 8 3/4, we get:

1 1/4(4.5) = 5 5/8

Since 5 5/8 cups of chocolate chips are needed for 4.5 batches of muffins, and Manuel has 8 3/4 cups of chocolate chips, this guess is too high. We need to revise our guess to a lower number of batches.

Let's try b = 4.25. Substituting b = 4.25 into the equation 1 1/4b = 8 3/4, we get:

1 1/4(4.25) = 5 5/16

Since 5 5/16 cups of chocolate chips are needed for 4.25 batches of muffins, and Manuel has 8 3/4 cups of chocolate chips, this guess is too high. We need to revise our guess to a lower number of batches.

Let's try b = 4.1. Substituting b = 4.1 into the equation 1 1/4b = 8 3/4, we get:

1 1/4(4.1) = 5 1/8

Since 5 1/8 cups of chocolate chips are needed for 4.1 batches of muffins, and Manuel has 8 3/4 cups of chocolate chips, this guess is too high. We need to revise our guess to a lower number of batches.

Let's try b = 4.05. Substituting b = 4.05 into the equation 1 1/4b = 8 3/4, we get:

1 1/4(4.05) = 5 1/16

Since 5 1/16 cups of chocolate chips are needed for 4.05 batches of muffins, and Manuel has 8 3/4 cups of chocolate chips, this guess is too high. We need to revise our guess to a lower number of batches.

Let's try b = 4.01. Substituting b = 4.01 into the equation 1 1/4b = 8 3/4, we get:

1 1/4(4.01) = 5

With this velocity , It take her to reach in  11.54 minutes or 0.1923 hours.

A vector number known as velocity describes "the rate at which an object changes its position."It is measured in meters per second (m/s) or kilometers per hour (km/h) and is defined as the rate at which the position of an item changes with regard to time.² A physical vector quantity called velocity must have both a magnitude and a direction in order to be defined.³

A graph of the woman's speed vs time would have a straight line with a positive slope, beginning at (0,0), and ending at (t,60), where t represents the amount of time it takes her to reach 60 mph.

Her initial velocity is zero because she starts at rest, and her final velocity is 60 mph. The following formula can be used to get the average acceleration during this period:

v_f - v_i = a / t

where t is the time it takes to reach 60 mph, an is the acceleration, v_f is the final velocity (60 mph), v_i is the starting velocity (0 mph), and an is the final velocity. Inverting this formula results in:

a = t = (v_f - v_i)

Inputting the values for v_f and v_i results in:

t = (60 mph - 0) / a

The formula: can be used to determine the acceleration.

a = d / t²

where d is the travelled distance (10 miles). Inputting the values for d and t results in:

a = 2d / t²

This expression for an is entered into the previous expression for t to produce the following result:

√(2d / a) = t

Adding the values for d and a results in:

t is equal to √(2× 10 miles / ((60 mph)2 - 0)) = 11.54 minutes or 0.1923 hours.

Therefore, the other two zeros of the function are approximately -1.802 and -0.198.

An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides separated by an equal sign (=). The expressions on both sides of the equation can contain variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. The goal in solving an equation is to find the value of the variable that makes the equation true. Equations are used extensively in mathematics and science to model real-world phenomena and solve problems.

by the question.

To find the zeros of the function, we need to solve the equation F(x) = 0. Since the given function has one known zero, which is 2 under the root, we can use this to simplify the expression.

Let's start by factoring out (x - 2^(1/2)) from the expression:

\(F(x) = (x - 2^(1/2))(6x^2 + 12x + 2^(1/2) - 4\sqrt{2})\)

Now we need to find the zeros of the quadratic factor:

\(6x^2 + 12x + 2^(1/2) - 4\sqrt{2} = 0\)

Using the quadratic formula, we get:

\(x = [-12±\sqrt((12)^2 - 4(6)(2^(1/2) - 4\sqrt{2}))]/(2(6))\)

Simplifying the expression under the square root gives:

\(\sqrt((12)^2 - 4(6)(2^(1/2) - 4\sqrt{2})) = \sqrt(144 - 24\sqrt{2} - 96) = sqrt(48 - 24\sqrt{2})\)

To solve the initial value problem  \(dy/dx = 2x\) with the initial condition y(0)=2 in Python, we can use an appropriate numerical method, such as Euler's method or the built-in function odeint from the scipy.integrate module.

Here's an example code snippet in Python that solves the given initial value problem using Euler's method:

import numpy as np

import matplotlib.pyplot as plt

def f(x, y):

   return 2*x

def euler_method(f, x0, y0, h, num_steps):

   x = np.zeros(num_steps+1)

   y = np.zeros(num_steps+1)

   x[0] = x0

   y[0] = y0

   for i in range(num_steps):

       y[i+1] = y[i] + h * f(x[i], y[i])

       x[i+1] = x[i] + h

   return x, y

x0 = 0

y0 = 2

h = 0.1

num_steps = 10

x, y = euler_method(f, x0, y0, h, num_steps)

plt.plot(x, y)

plt.xlabel('x')

plt.ylabel('y')

plt.title('Solution of dy/dx = 2x')

plt.show()

In this code, we define the function f(x, y) that represents the right-hand side of the differential equation. Then, we implement the Euler's method in the euler_method function, which takes the function f, the initial values x0 and y0, the step size h, and the number of steps num_steps as inputs. The method iteratively calculates the values of x and y using the Euler's method formula. Finally, we plot the solution using matplotlib.pyplot. Running the code will generate a plot showing the solution of the initial value problem dy/dx = 2x with y(0)=2 over the specified range of x-values.

The height  of the box that has the smallest possible surface area is  20m .

In the question ,

it is given that ,

the box has a square base ,

let the side of the box = "x" m

and let the height of the box = "y" m

volume of the box is given as 32000 m³,

So , x²y = 32000

y = 32000/x²

let the surface area of the box be "S" , that means

surface area(S) = area of base + total area of the 4 sides

= x²y + 4xy

Substituting the value of y = 32000/x² , we get

= x² + 4x(32000 / x²)

= x² + 128,000 / x,       x > 0

to minimize the area we differentiate it with respect to x,

we get ,

= 2x - 128,000 / x²

= (2x³ - 128,000) / x²

Substituting S' = 0 ,  we get , 2x³ = 128,000

x³ = 64,000

x = 40

and y = 32000/(40)² = 20 m .

The magnitude of an earthquake that is 35 times more intense than a standard earthquake is 1.5.

The magnitude of an earthquake is the measured of the amplitude r the size of the seismic waves which is produced by the earthquake.

The magnitude, m, of an earthquake is defined to be

\(m = \log\left( \dfrac{I}{S}\right)\)

Here (I) is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and (S) is the intensity of a "standard" earthquake, which is barely detectable.

The magnitude of an earthquake that is 35 times more intense than a standard earthquake has to be find out. The Intensity of this earth quack can be given as,

\(I=35S\)

Put this values in the above formula as,

\(m = \log\left( \dfrac{35 S}{S}\right)\\m = \log\left( 35 \right)\\m\approx 1.5\)

Percentages are just fractions with the denominator 100. We use the percent symbol (%) to indicate that a number is a percentage. For example, if you correctly answered 75 out of 100 questions on a test, you would have gotten a 75% (75/100) mark.

Divide the amount by the total value and multiply the result by 100 to get the percentage. (Price/Total Price) The formula for computing percentages is 100%.

If 60% of the votes were in favor of working in groups, that means there were 60/100 * 10 votes = <<60/100*10=6>>6 votes in favor.

Answer:

y = 3x + 37

Step-by-step explanation:

Let's look for an equation of the form y=mx+b, whre m is the slope and b is the y-intercept (the value of y when x = 0).  The slope, m, can be calculated from the two given points:  (-5,22) and (4,49).

Slope is defined as the Rise/Run of the line.  That is, how much the line rises (or falls) per unit change in the run, or x value.  Take the two points and calculate the Rise and Run:

From (-5,22) to (4,49)

Rise is (49 - 22) or 27  [The final value minus the initial value of y].

Run is (4 - (-5)) = 9  [The final value miuns the initial value of y].

Slope is Rise/Run or 27/9 = 3;  m = 3

So we can write y = 3x +b

We need to find a value of b that forces the line through the two points.  Easy:  Just enter one of the points in the equation we have thus far, and solve for b:

 y = 3x +b

 22 = 3(-5) +b  for (-5,22)

22 = -15 + b

b = 37

The equation becomes y = 3x + 37.

The amount of chlorine in the pool at the start of any given week, we need to know the amount of chlorine in the pool at the start of the previous week.

Let Cn be the amount of chlorine in the pool at the start of the nth week.

We can start by finding the amount of chlorine in the pool at the start of the second week. Since 40% of the chlorine evaporates, we have:

C2 = 0.6(C1 + 16)

Now, we can use this formula to find the amount of chlorine in the pool at the start of the third week:

C3 = 0.6(C2 + 16)

We can continue this process to find a recursive rule for Cn:

Cn = 0.6(Cn-1 + 16)

where C1 = 34.

This formula tells us that to find the amount of chlorine in the pool at the start of any given week, we need to know the amount of chlorine in the pool at the start of the previous week. We can use this formula repeatedly to find the amount of chlorine in the pool at the start of any week.
