Find the equation of the curve that passes through the point 0, 1 6 and whose slope at each point (x, y) is − x 12y .
The equation is [tex]\(x^2 + 12y^2 - 3072 = 0\),[/tex] obtained from integrating [tex]\(12y \, dy = -x \, dx\)[/tex] with the initial condition.
To find the equation of the curve passing through the point (0, 16) with a slope given by [tex]\( \frac{{dy}}{{dx}} = -\frac{x}{12y} \),[/tex] you can use separation of variables.
Given that [tex]\( \frac{{dy}}{{dx}} = -\frac{x}{12y} \)[/tex], we can rewrite it as:
[tex]\[ 12y \, dy = -x \, dx \][/tex]
Now, integrate both sides:
[tex]\[ \int 12y \, dy = \int -x \, dx \]\[ 6y^2 = -\frac{1}{2}x^2 + C \][/tex]
Given that the curve passes through the point (0, 16), substitute these values into the equation:
[tex]\[ 6(16)^2 = -\frac{1}{2}(0)^2 + C \]\[ 6(256) = C \]\[ C = 1536 \][/tex]
Therefore, the equation of the curve is:
[tex]\[ 6y^2 = -\frac{1}{2}x^2 + 1536 \][/tex]
This can also be written in standard form as:
[tex]\[ x^2 + 12y^2 - 3072 = 0 \][/tex]
So, the equation of the curve is [tex]\( x^2 + 12y^2 - 3072 = 0 \).[/tex]
Generate a process that would generate random numbers between –1 and 1 for x and y positions of 10000 points and count how many points fall with the circle, then determine an estimated version of π. (see below to generate floating point random numbers. this generation is not needed to describe the process, but to implement the process)
The question is about using the Monte Carlo method to estimate the value of π, by generating random points in a square, counting how many fall inside a unit circle, and finally using this count to calculate π.
Explanation:This question involves the implementation of a famous problem in computational mathematics known as the Monte Carlo method for estimating the value of π:
First, initialize a variable, say 'count', to 0. This variable will keep track of the number of points falling within the circle.Next, carry out a 'for' loop to generate 10000 points. Each point will have x and y coordinates, each a random floating point number between -1 and 1.For each generated point (x, y), calculate the distance from the point to the origin (0,0), which is sqrt(x^2 + y^2). If this distance is less than or equal to 1, it means that the point lies within the unit circle, so increment the 'count' variable by one.After all 10000 points have been generated and tested, 'count' will hold the total number of points lying within the circle. To determine an estimation of π, use the formula 4 * (count / total_number_of_points).This process is based on the mathematical fact that the ratio of the area of a unit circle to the square it is inscribed in is π/4.

2. During a 5-day training at your department, the number of visitors tripled each day. If the training started on a Monday with 345 attendees, what was the attendance on Thursday?
The number of attendance on Thursday would be 9,315.
Given that,
During a 5-day training at your department, the number of visitors tripled each day.
Here, the training started on a Monday with 345 attendees.
Hence, the number of visitors on Tuesday is 3 times with 345 attendees.
That is, On Tuesday;
Number of attendees = 345 x 3
= 1,035
On Wednesday;
Number of attendees = 1,035 x 3
= 3,105
On Thursday;
Number of attendees = 3,105 x 3
= 9,315

The floor of a one-story building is 14 feet longer than it is wide. The building has 1715 square feet of floor space. Find the length l and width w of the floor.
Final answer:
To find the floor dimensions of a building that is 14 feet longer than it is wide with an area of 1715 sq ft, we solve the quadratic equation w * (w + 14) = 1715, resulting in w=100 feet and length l=114 feet.
Explanation:
The student is asked to find the length (l) and width (w) of a one-story building floor which is 14 feet longer than it is wide, with a total area of 1715 square feet. To solve this, we set up an equation where w represents the width and w + 14 feet represents the length. Since the area of a rectangle is length times width, the equation is w * (w + 14) = 1715.
After solving this quadratic equation, we find that w=100 feet which makes the length l = w + 14 = 114 feet. Therefore, the actual dimensions of the building are 114 ft by 100 feet.

Find y'' by implicit differentiation. 5x3 + 2y3 = 1
The value of y'' will be (- 5x/y² - 25x⁴/2y⁵).
What is implicit differentiation?
In implicit differentiation, we differentiate each side of an equation with two variables by treating one of the variable as a function of other.
Given that;
The equation is;
5x³ + 2y³ = 1
Now, Apply implicit differentiation rule we get;
5x³ + 2y³ = 1
After differentiation;
15x² + 6y² dy/dx = 0
dy/dx = - 15x² / 6y²
dy/dx = -5x²/2y²
Again differentiation;
d²y/dx² = -5/2 (y² × 2x - x² × 2y dy/dx) / y⁴
d²y/dx² = -5/2 (2xy² - 2x²y dy/dx) / y⁴
Substitute value of dy/dx;
d²y/dx² = - 5/2 (2xy² - 2x²y × -5x²/2y²) / y⁴
d²y/dx² = - 5/2 (2xy² + 5x⁴/y) / y⁴
d²y/dx² = - 5x/y² - 25x⁴/2y⁵
y'' = - 5x/y² - 25x⁴/2y⁵
Thus, The value of y'' will be (- 5x/y² - 25x⁴/2y⁵).

Shantel is studying for her history test. After 20 minutes she is 1/4 of the way done. How much longer will she study?
Shantel will need to study for 60 minutes more to complete her history review.
Shantel is studying history and after 20 minutes, she is [tex]\frac{1}{4}[/tex] of the way done.
To determine how much longer she will study, we need to calculate how much time is needed to complete the remaining [tex]\frac{3}{4}[/tex] of her study time.
[tex]\frac{1}{4}[/tex] of the study done in 20 minutes means she will study for 4 * 20 = 80 minutes in total.
To find out how much longer she needs to study, subtract the time she has already studied (20 minutes) from the total study time (80 minutes): 80 - 20 = 60 minutes.
Therefore, Shantel will need to study for 60 minutes more to complete her history review.
