When a polygon reflects across the y axis ,how do the coordinates of the points change

Answers

Answer 1

The y coordinate will stay the same. The x coordinate will flip from positive to negative, or vice versa.

Some examples:
(1,2) ----> (-1,2)
(-3,4) ----> (3,4)
(-1.2, 8) ----> (1.2, 8)

The general rule is
(x,y) ----> (-x, y)
indicating that only the x coordinate undergoes a change

Estimate sin pi/3 if sin pi/2 = 1 and sin 0 = 0 and sin pi = 0

Answers

hello :
sin(π/3) = √3 / 2

Final answer:

To estimate the value of sin pi/3, which is roughly 1.047 or 60 degrees, we can use standard trigonometric values. Since pi/3 is closer to pi/2 than pi, where sin achieves its maximum of 1, the value of sin pi/3 should be closer to 1 than 0. Standard trigonometric values confirm that sin pi/3 = sqrt(3)/2 = 0.866.

Explanation:

To estimate sin pi/3, we can make use of some standard values in trigonometry. Pi is roughly 3.14, hence pi/3 is roughly 1.047. The sin function gives a result of 1 at pi/2 (or 90 degrees), 0 at 0, and again 0 at pi (or 180 degrees). Thus, it achieves its maximum at pi/2 and then decreases to 0 at pi. Intuitively, since pi/3 (or 60 degrees) is closer to pi/2 than to pi, the sin value at pi/3 should be closer to 1 than to 0. From the standard trigonometric values, we know that sin pi/3 = sqrt(3)/2 which is roughly 0.866.

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 .

Answers

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]

The sum of three consecutive numbers is 72. What is the largest of these numbers?

Answers

3 consecutive numbers....x, x + 1 and x + 2

x + x + 1 + x + 2 = 72
3x + 3 = 72
3x = 72 - 3
3x = 69
x = 69/3
x = 23

x + 1 = 23 + 1 = 24
x + 2 = 23 + 2 = 25

so ur numbers are 23,24,25 with 25 being the largest

You have inadvertently left out some of the instructions for this problem.

22 + 0.15p =c could be solved for p; that's one thing you could do now.

Subtracting 22 from both sides, 0.15p = c - 22

Dividing both sides by 0.15, p = (c-22)/0.15 , or p = (20/3)(c-22).

A car travels 182 miles in 3 hours and 15 minutes. How many miles does it travel per hour?

Answers

To solve this, we'll use the formula distance=rate*time. There's just one problem here: we need all of our time to be in the same units. Let's convert the 15 minutes into hours:
[tex]15min*\frac{1hour}{60min}=0.25hr[/tex]

Then we just use the formula:
[tex]d=182*0.25[/tex]

15 minutes = 15/60 = 0.25 hrs + the 3 hrs = 3.25 hrs

182 / 3.25 = 56 miles per hr

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).

solve the following equation for 2 + √4y -3 = 11

Answers

2+√4y-3=11
2+√4y=11+3=14
√4y=14-2=12
root 4y=2y
2y=12,divide both side by 2
y=6

Final answer:

To solve the equation 2 + √(4y - 3) = 11 for y, subtract 2 from both sides, square both sides to remove the square root, then solve for y to find that y = 21.

Explanation:

The question asks to solve the equation 2 + √(4y - 3) = 11 for y. To solve for y, follow the steps below:

First, subtract 2 from both sides of the equation to isolate the square root term: √(4y - 3) = 9.

Now, square both sides of the equation to eliminate the square root: (√(4y - 3))^2 = 9^2, which simplifies to 4y - 3 = 81.

Add 3 to both sides of the equation to isolate the term with y: 4y = 84.

Finally, divide both sides by 4 to solve for y: y = 21.

Therefore, the solution to the equation is y = 21.

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.

if d < 1: count_inside += 1
count += 1
print 4.0 * count_inside / count

Final answer:

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.
