∫(f(x) + g(x)) dx = ∫f(x) dx + ∫g(x) dx is the sum rule in integration.

The sum rule in integration states that if f(x) and g(x) are two functions that are both integrable over a given interval, then the integral of the sum of these functions over that interval is equal to the sum of the integrals of the individual functions over that interval. Mathematically, this can be expressed as:

∫(f(x) + g(x)) dx = ∫f(x) dx + ∫g(x) dx

The sum rule of integration is: Integral of the sum of two functions is equal to the sum of integration of individual functions.

The 2 real solutions are rational and irrational solutions.

Quadratic Formula is the simplest method to find the roots of a quadratic equation. There are particular quadratic equations that cannot be easily factorized, and here we use this quadratic formula to find the roots in the quickest possible way.

Quadratic Formula: The roots of a quadratic equation ax² + bx + c = 0 are given by x = [-b ± √(b² - 4ac)]/2a.

The value b² - 4ac is called the discriminant of a quadratic equation and is represented as 'D'. The nature of the roots of the quadratic equation can be predicted based on the discriminant value.

If D > 0, the roots are real and distinct (two real solutions).

If D = 0, the roots are real and equal (one real solution).

If D < 0, the roots do not exist, or they are imaginary (two imaginary solutions).

The coordinates of the vertex of the function y = -3x² -12x + 3 is (-2,15) and the graph of the function is attached below.

Vertex in math is known as a point on a polygon where the sides or edges of the object meet or where two rays or line segments meet.

Here we have given that the function y = -3x² - 12x + 3 and we have to find the coordinates of the vertex.

As we all know that for any equation of the type y = ax² + bx + c the vertex is given by (h, k)

And the value of the vertex is calculated by using the formula  h = -b/2a and k = (4ac - b2)/4a.

From the given question we have identified the value of  a = -3, b = -12 and c = 3

Then the value of h is calculated as,

=> h = -(-12)/2(-3)

When we simplify this one then we get the value of h as -2

Similarly the value of k is calculated as,

=> 4ac = 4(-3)(3) = -36

Then the equation is written as,

=> k = [-36 - (-12)2]/4(-3)

When we simplify this one then we get

=> k = -180/-12

Therefore, the value of k is 15

Hence the coordinates of the vertex is (h, k) = (-2, 15).

Correctly written question:

Write an algebraic expression that represent the sum of y to the fifth power and eleven

Answer:

23.6 units.

Step-by-step explanation:

Since quadrilateral DEFG is similar to quadrilateral HIJK, the ratios of corresponding sides are equal. We can use this information to find the measure of IJ.

We know that:

DF/HJ = EF/IJ = 6/23.6 = 2/8 = 1/4

So we can set up the proportion:

IJ/EF = HJ/DF

IJ/6 = 23.6/6

IJ = 23.6/6 * 6 = 23.6

When you solve an equation for one variable and then substitute the resulting expression in for that variable in the other equation its is known as Substitution method.

I will demonstrate how the substitution method works. Suppose we have the following systems of linear equations with two variables:

Equation 1:  3x + 2y = 11

Equation 2:  -x + y = 3

By solving these two equations we get x=1 and y=4.

Equation 2:  -x + y = 3

-x + x + y = x + 3

y = x + 3

Next, substitute the value of y in Equation 2 (from the previous step), and substitute its value into Equation 1 to solve for x:

Equation 1:  3x + 2y = 11

Substitute y = x + 3 into Equation 1:

3x + 2(x + 3) = 11

3x + 2x + 6 = 11

Combine like terms:

5x + 6 = 11

5x + 6 - 6 = 11 - 6

5x = 5

Divide both sides by 5 to solve for x:

[tex]\frac{5x}{5} = \frac{5}{5}[/tex]

x = 1

Substitute the value of x into Equation 2 to solve for y:

Equation 2:  -x + y = 3

-1 + y = 3

y = 3 + 1

y = 4

Answer:

The given expression is -7xy^3z^2

The degree of x is 1

The degree of -7 is 0

The degree of y^3 is 3

The degree of z^2 is 2

The degree of a polynomial is the highest exponent of its variables. In the case of the polynomial -7xy^3z^2, the degree is the highest exponent among x, y, and z.

The highest exponent is 3, which is the exponent of y. So the degree of the polynomial -7xy^3z^2 is 3.

It's worth noting that the coefficient -7 has no effect on the degree of the polynomial. The degree of a polynomial is determined by the exponents of its variables, not its coefficients.

95% of toy eskimo dogs have weight between 6.04 and 9.96 pounds assuming normal distribution.

What is weight ?

Weight is a measure of the force exerted on an object due to gravity. It is typically measured in units of mass such as kilograms (kg) or pounds (lbs). The weight of an object can be determined by multiplying its mass by the acceleration due to gravity.

Assuming the weights of toy eskimo dogs are normally distributed, we can use the standard normal distribution table to find the range of weights that would include 95% of the dogs.

The standard normal distribution table gives the proportion of data within a given number of standard deviations from the mean. Since the standard deviation of the toy eskimo dog's weight is 1 pound, we can use this table to find the range of weights that are within 1.96 standard deviations from the mean.

Using this method, we can find that 95% of the toy eskimo dogs will have a weight that is between 6.04 pounds (8 - 1.96) and 9.96 pounds (8 + 1.96).

95% of toy eskimo dogs have weight between 6.04 and 9.96 pounds assuming normal distribution.
