What is a circle equation?The equation of circle provides an algebraic way to describe a circle, given the center and the length of the radius of a circle. The equation of a circle is different from the formulas that are used to calculate the area or the circumference of a circle.
The standard equation of a circle with center at (x₁, y₁) and radius r is (x-x₁)²+(y-y₁)²=r²
Given that, the point P= (x, 1/3) lies on the unit circle
x²+ y²= 1
x²+ (1/3)²= 1²
x²+1/9=1
x²=1-1/9
x=√8/9
x=2√2/3

find two numbers whose difference is 164 and whose product is a minimum.
Answer: The lowest possible product would be -6724 given the numbers 82 and -82.
We can find this by setting the first number as x + 164. The other number would have to be simply x since it has to have a 164 difference.
Next we'll multiply the numbers together.
x(x+164)
x^2 + 164x
Now we want to minimize this as much as possible, so we'll find the vertex of this quadratic graph. You can do this by finding the x value as -b/2a, where b is the number attached to x and a is the number attached to x^2
-b/2a = -164/2(1) = -164/2 = -82
So we know one of the values is -82. We can plug that into the equation to find the second.
x + 164
-82 + 164
82

A beam of light bends when it passes from air into water, and then bends even more when it passes from water into glass. What can you conclude from this fact?
Select one:
a.
air is denser than water
b.
water is denser than glass
c.
air is denser than glass
d.
glass is denser than water
Glass is denser than water. The correct answer is option d
What is Refraction ?Refraction is the bending of a light ray as it crosses the boundary between two media of different densities, thus causing a change in its direction.
Given that a beam of light bends when it passes from air into water, and then bends even more when it passes from water into glass.
Light rays do bend when they cross from less dense medium to a denser medium and vice versa.
We can therefore conclude from this fact that glass is denser than water.

The equation of a line is y=4/3x + 4 . Is the point (6, 13) on the line? [ Select ] Is the point (9, 16) on the line?
The point (9, 16) is on the line.
Given,
The equation of the line = y = 4/3x + 4
We have to find whether the given points are on this line or not.
For that substitute the points into the equation.
That is,
Point (6, 13)
x = 6 and y = 13
Equation;
y = 4/3x + 4
13 = 4/3 x 6 + 4
13 = 8 + 4
13 ≠ 12
That is, the point (6, 13) is not in the line.
Next,
Point (9, 16)
x = 9 and y = 16
Equation;
y = 4/3x + 4
16 = 4/3 x 9 + 4

.
The value of the car after 8 years will be y = $10,000.
What is linear equation ?linear equation is an algebraic equation of the form y=mx+c .
. the two data points to a linear equation in slope-intercept form:
slope = (11000 - 15000) / (5 - 3) = -2000 / 2 = -1000
Using the point-slope form of a linear equation with point (3, 15000):
y - 15000 = -1000(x - 3)
y - 15000 = -1000x + 3000
y = -1000x + 18000
Now x = 8 to find the value of the car after 8 years:
y = -1000(8) + 18000 = $10,000
Therefore, the value of the car after 8 years will be $10,000.

Step-by-step explanation:
The given triangle is a right triangle, this is indicated by the box around one of the angles, signifying that the angle is a (90) degree angle. Therefore, to solve this problem one must use trigonometric ratios. These ratios are used to describe the relationship between an angle and the sides in a right triangle.
\(sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}\\\)
Bear in mind, the names of the sides of the triangle are relative to the angle that one uses to describe it in the triangle. Therefore the (opposite) and (adjacent) sides will change depending on the angle one chooses to look at it from.
In this case, one is given the length of the side opposite the given angle. One is asked to find the measure of the side adjacent to the angle. Therefore, it would make the most sense to use the tangent (tan) ratio.
\(tan(\theta)=\frac{opposite}{adjacent}\)
Substitute,
\(tan(20)=\frac{9}{x}\)
Manipulate the equation such that it is solved for (x),
\(x=\frac{9}{tan(20)}\)

Answer:
The values of x are:
x : -3, -2, -1, 0, 1, 2, 3
Let's solve each by putting each value of x into each equation:
a \(y = 2^x\)
> x = -3
=> y = 2^(-3) = 1/8
> x = -2
=> y = 2^(-2) = 1/4
> x = -1
=> y = 2^(-1) = 1/2
> x = 0
=> y = 2^0 = 1
> x = 1
=> y = 2^1 = 2
> x = 2
=> y = 2^2 = 4
> x = 3
=> y = 2^3 = 8
b. \(y = -2^x\)
> x = -3
=> y = -2^(-3) = -1/8
> x = -2
=> y = -2^(-2) = -1/4
> x = -1
=> y = -2^(-1) = -1/2
> x = 0
=> y = -2^0 = -1
> x = 1
=> y = -2^1 = -2
> x = 2
=> y = -2^2 = -4
> x = 3
=> y = -2^3 = -8
c. \(y = (3)(2^x)\)
> x = -3
=> y = 3 * 2^(-3) = 3 * 1/8 = 3/8
> x = -2
=> y = 3 * 2^(-2) = 3 * 1/4 = 3/4
> x = -1
=> y = 3 * 2^(-1) = 3 * 1/2 = 3/2
> x = 0
=> y = 3 * 2^0 = 3 * 1 = 3
> x = 1
=> y = 3 * 2^1 = 3 * 2 = 6

Imagine some DEQ: y'=f(x,y), which is not given in this exercise.
Use Euler integration to determine the next values of x and y, given the current values: x=2, y=8 and y'=9. The step size is delta_X= 5. 2 answers
Refer to the LT table. f(t)=6. Determine tNum,a,b and n. 4 answers
Using Euler integration, the next values of x and y can be determined as follows:
x_next = x_current + delta_X
y_next = y_current + delta_X * y'
What are the updated values of x and y using Euler integration?Euler integration is a numerical method used to approximate solutions to differential equations. It is based on the concept of dividing the interval into small steps and using the derivative at each step to calculate the next value. In this case, we are given the current values of x=2, y=8, and y'=9, with a step size of delta_X=5.
To determine the next values of x and y, we use the following formulas:
x_next = x_current + delta_X
y_next = y_current + delta_X * y'
Substituting the given values into the formulas, we have:
x_next = 2 + 5 = 7
y_next = 8 + 5 * 9 = 53
Therefore, the updated values of x and y using Euler integration are x=7 and y=53.
It's important to note that Euler integration provides an approximate solution and the accuracy depends on the chosen step size. Smaller step sizes generally lead to more accurate results. Other numerical methods, such as Runge-Kutta methods, may provide more accurate approximations.

What is the equation of the line that passes through the point (-2,0) and has a slope of -2
Answer:
y = -2x -4
Step-by-step explanation:
The equation of a line is y = mx + b, where m is the slope of the line, and b is the y-intercept. We are told that the slope of the line is -2, so we can start with
y = mx + b
y = -2x + b
We can figure out the value of b by plugging in the coordinates of the point given (-2, 0)
0 = -2(-2) + b
0 = 4 + b
Subtract 4 from both sides of the equation
-4 = b
Then plug that value of b back into the equation above:
y = -2x + (-4) or y = -2x -4
Answer:
y=mx+c
we will find c
0=(-2)(-2)+c
c=-4
y=-2x+(-4)
y=-2x-4
2x+y+4=0

Answer:

Step-by-step explanation:
The perimeter of a rectangle with a length of 9x - 4 and a width of (5x + 2) will be 18x - 4.
What is the perimeter of the rectangle?Let W be the rectangle's width and L its length. The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be given as,
Perimeter of the rectangle = 2(L + W) units
The dimension of the rectangle is given as,
L = 9x - 4
W = 5x + 2
Then the perimeter of the rectangle is given as,
P = 2(L + W)
P = 2(9x - 4 + 5x + 2)
P = 2(14x - 2)
P = 18x - 4
The perimeter of a rectangle with a length of 9x - 4 and a width of (5x + 2) will be 18x - 4.
