Factorise x^2 + 6x - 27

The missing value of the first coordinate x is 9.

Slope is simply expressed as change in y over the change in x.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Given the data in the question;

Point A (x,8)

Point B (4,-7)

Slope m = 3

Plug the given coordinates into the slope formula and and solve for x.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

3 = ( -7 - 8 )/( 4 - x )

Cross multiply

3( 4 - x ) = ( -7 - 8 )

12 - 3x = -7 - 8

12 - 3x = -15

-3x = -15 - 12

-3x = -27

x = -27 / -3

x = 9

Therefore, the value of x is 9.

Answer:

[tex]\displaystyle{\text{possible rational roots} = \pm 1, \pm \dfrac{1}{2}, \pm 3, \pm \dfrac{3}{2}, \pm 9, \pm \dfrac{9}{2}, \pm 27, \pm \dfrac{27}{2}}[/tex]

Step-by-step explanation:

Rational Root theorem is when we divide the factors of last term by the factors of first term:

[tex]\displaystyle{\text{possible rational roots} = \dfrac{\text{factors of the coefficient of last term (constant)}}{\text{factors of lead coefficient (coefficient of first term)}}}[/tex]

Our constant (last term) is -27. The factors of -27 can be ±1, ±3, ±9, ±27

Our lead coefficient is 2. The factors of 2 can be ±1 and ±2.

Hence:

[tex]\displaystyle{\text{possible rational roots} = \dfrac{\pm 1, \pm 3, \pm 9, \pm 27}{\pm 1, \pm 2}}\\\\\displaystyle{\text{possible rational roots} = \pm 1, \pm \dfrac{1}{2}, \pm 3, \pm \dfrac{3}{2}, \pm 9, \pm \dfrac{9}{2}, \pm 27, \pm \dfrac{27}{2}}[/tex]

All of these are possible roots, meaning that not all of them are real roots of the equation, just a possibility.

The standard equation of a line is expressed as y = mx + b

m is the slope

b is the y-intercept

Given the equation y = 2x - 2

If x = -2

y = 2(-2) - 2

y = -4-2

y = -6

If x  = 4

y = 2(4) - 2

y = 8-2

y = 6

The correct answer is option 1. In a continuous probability distribution, the random variable can take on an infinite number of values within a given range.

This range is typically represented by the interval between two points on the number line, such as 0 and 100. The probability of a particular value occurring is defined as the area under the curve of the probability density function for that distribution, rather than a single value.

Option 2, "may have a probability greater than 1.00" is incorrect as probabilities are always between 0 and 1, inclusive.

Option 3, "has a limited number of values" is incorrect as, by definition, continuous random variables can take on an infinite number of values.

Option 4, "is discrete" is incorrect as a continuous random variable is not limited to a finite or countable number of values.

This is an equation is e⁻¹³⁸ˣ - 5e⁻¹³⁹ × 81y + z = 6

In mathematics, a tangent is a line that touches a curve at a single point and has the same slope as the curve at that point. The tangent can be thought of as an approximation of the curve at the point where it touches it.

The concept of the tangent is used in calculus and other branches of mathematics to study the properties of curves and to analyze their behavior. The derivative of a function at a point is defined as the slope of the tangent to the curve of the function at that point. The derivative is a fundamental concept in calculus and is used to study the rate of change of a function, the optimization of functions, and to solve problems in many different fields.

To find the equation of the tangent plane to the surface z = e^(x - y^5) at the point (3, 3, 6), we need to find the normal vector of the surface at that point, and use that to find the equation of the plane.

The normal vector can be found using the gradient of the surface, which is given by the partial derivatives of the function:

∇f = ∇(e^(x - y^5)) = (e^(x - y^5), -5e^(x - y^5)y^4, 1)

Evaluating this at the point (3, 3, 6), we get:

∇f(3, 3, 6) = (e^(3 - 3^5), -5e^(3 - 3^5)3^4, 1) = (e^-138, -5e^-138 * 81, 1)

So the normal vector of the surface at the point (3, 3, 6) is (e^-138, -5e^-138 * 81, 1).

To find the equation of the tangent plane, we need to find a point on the plane, and use that along with the normal vector. We already know that the point (3, 3, 6) is on the surface, so we can use that as a point on the plane.

Using the point-normal form of a plane, the equation of the tangent plane is given by:

ax + by + cz = d

Where (a, b, c) is the normal vector and (x⁰, y⁰, z⁰) is a point on the plane.

Substituting the values, we get:

e⁻¹³⁸ˣ - 5e⁻¹³⁹ × 81y + z = 6

This is the equation of the tangent plane to the surface z = e^(x - y^5) at the point (3, 3, 6).

Li's mystery polygon has 4 sides and no pairs of parallel sides, which means it is a quadrilateral.

A trapezoid is a quadrilateral with exactly one pair of parallel sides and no two angles that add up to 180 degrees.

A trapezoid with two right angles (90 degrees) is called a right trapezoid. Since Li's mystery polygon has one angle that measures 90 degrees, it is likely a right trapezoid.

Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent

The tangent line to the parabola y = x² at the point (6, 36) is (0.141, 1.68)

The equation of the tangent line at the point (6, 36) can be found using the derivative of the function and the point-slope form of a line:

f(x) = x²

f'(x) = 2x

y = f'(x) * (x - 6) + 36

Substituting f'(x) = 2x,

y = 2x * (x - 6) + 36

Now, we can find a unit vector that is parallel to this line by finding a non-zero multiple of the direction vector of the line, which is (1, 2x), and normalizing it.

To normalize, we divide by the magnitude, which is sqrt(1^2 + (2x)^2) = sqrt(1 + 4x^2).

Let's use x = 6:

y = 2 * 6 * (x - 6) + 36

y = 72

So, the direction vector is (1, 12) and its magnitude is sqrt(1 + 144) = sqrt(145) = 7.07.

If for a particular x, and y values are coming it means it is not a function. If it crosses y-axis twice it means for a particular x value , two different value of y will exist.

From the graph, we know that limit at point a is:

lim (x→a) f(x) exists if and only if

lim (x →a⁺) f(x) = lim (x→a⁻) f(x) and ≠ ∞
