The derivative of 7e to the 7x is 7e to the 7x * 7ln(e) * 7. The derivative of 7e to the 7x can be found by first taking the natural logarithm of the base, in this case e7x.

1. Take the natural logarithm of the base: ln(e7x)

2. Take the derivative of the natural logarithm: 7x*ln(e)

3. Apply the chain rule: 7e7x * 7ln(e) * 7

The derivative of 7e to the 7x can be found by first taking the natural logarithm of the base, in this case e7x. The natural logarithm of e7x is ln(e7x). Taking the derivative of the natural logarithm yields 7x*ln(e). We then apply the chain rule to get the final result of 7e7x * 7ln(e) * 7. In other words, the derivative of 7e to the 7x is equal to 7 multiplied by e raised to the 7x power, multiplied by 7ln(e), and then multiplied by 7 once more. This can be simplified to 7e7x * 7ln(e)7.

Yes, the quadratic parent function is the parabola.

The term parent function in math is defined as the simplest function of a family of functions that preserves the definition or shape of the entire family.

Here we have to identify that whether the quadratic parent function is a parabola or not.

According to the definition of parent function, the quadratic parent function is written as,

=> f(x) = x²

And here we also know that the quadratic function is one of the form

Using Sabah's function, ($1125, $500) is the right ordered pair. It is not a function if any of the x values are the same, but this is not true if the y values are different.

A set of ordered pairs is not a function if an x value has more than one y value associated with it. For instance, in the relation (4, 1), (4, 2), the x-value of 4 has y-values of 1 and 2, indicating that this relation is not a function. The connection is a function if each x-value has a single corresponding y-value.

An ordered group of pairs makes up a relation (x, y). A pair that has two values stated in a specific order between parenthesis is known as an ordered pair. It is made up of the x coordinate (abscissa) and the y coordinate (ordinate). For greater visual comprehension, it helps to locate a point on the Cartesian plane. An ordered pair of numbers can have either fractional or integer values.

The smallest integer greater than 38 which cannot be the length of the hypotenuse of a right triangle is 39.

Since 39 is divisible by 3, it cannot be the hypotenuse in any Pythagorean triples. Because for primitive Pythagorean triples, the hypotenuse is never divisible by 3.

A primitive Pythagorean triple is one where a, b and c are coprime (which is, they have no common divisor larger than 1). For example, (3, 4, 5) is a primitive Pythagorean triple while (6, 8, 10) is not. For any primitive Pythagorean triple the integer c or the hypotenuse cannot be divisible by 3. Divisibility by 3 is only reserved for spots a and b.

There are an infinite number of Pythagorean triples. If 2n+1 is a square, it forms a Pythagorean triple. But 2n+1 comprises all the odd numbers; each of other square numbers is odd; there are an infinite number of odd squares; thus, there are an infinite number of Pythagorean triples.

Since triangle A'B'C' is an image of triangle ABC after a rotation and the center of rotation is D, the length of side B'C' is equal to 4 units.

In Mathematics, a rotation can be defined as a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.

Generally speaking, rotation simply refers to a type of transformation that preserves both the shape and side lengths of a geometric figure.

In this context, we can reasonably infer and logically deduce that the magnitude of side length BC before a rotation of the triangle would be equal to side length BC B'C' after rotation:

Side BC = side B'C'

4 = 4

In conclusion, the length of side B'C' is equal to 4 units.

The answer to the polynomial x^2 + 9x + 20 is x^2 + 9x + 20.

This is a second-degree polynomial, which is a polynomial with the highest power of the variable being 2. It is written in the standard form as ax^2 + bx + c, where a, b, and c are coefficients, and x is a variable. In this case, a = 1, b = 9, and c = 20.

To calculate this polynomial , we first substitute each value into the formula:

1x^2 + 9x + 20

Next, we multiply each coefficient with its corresponding variable:

1(x^2) + 9(x) + 20

Finally, we expand the terms and add them together to find the sum:

The slope of the line (-3, 4) and (0, 2) is -2/3.

In the given question, we have to find the slope of the line (-3, 4) and (0, 2).

A line's slope is defined as the ratio of the change in the y coordinate to the change in the x coordinate.

The given points are (-3, 4) and (0, 2).

We can find the slope from the given point using the formula

m = [tex]\frac{y(2)-y(1)}{x(2)-x(1)}[/tex]

From the given points;

x(1) = -3, y(1) = 4, x(2) = 0, y(2) = 2

Now putting the values in the formula;

m = (2 - 4)/(0 - (-3))

m = (-2)/(0 + 3)

m = -2/3

The quadratic equation in its standard form is;

ax² + bx + c = 0

Where x is the unknown

To solve for x, we use the quadratic formula

x = (-b±√(b² - 4ac)) / (2a)

Given the equation in the question;

x² + 3x - 5 = 0

Hence;

a = 1

b = 3

c = -5

We substitute this values into the quadratic formula above.

x = (-b±√(b² - 4ac)) / (2a)

x = ( -3 ± √( 3² - ( 4 × 1 × -5) )) / ( 2 × 1)

x = ( -3 ± √( 9 - ( -20 ) )) / ( 2 )

x = ( -3 ± √( 9 + 20 )) / 2

x = ( -3 ± √( 29 )) / 2

x = ( -3 - √( 29 ))/2, x = ( -3 +√( 29 ))/2

When the parent graph of the equation, y = √x is changed to y = -√x + 1, the following statements are true:

B. shift down one unit.

C. reflect over the x-axis.

In Mathematics, the translation a geometric figure or graph downward simply means subtracting a digit from the value on the y-coordinate (y-axis) of the pre-image or function.

Next, we would translate the parent graph of the equation down by one unit;

y = √x - (k)

y = √x - (-1)

y = √x + 1

In Geometry, a reflection over the x-axis is given by this transformation rule (x, y) → (x, -y). This ultimately implies that, a reflection over the x-axis would maintain the same x-coordinate while the sign of the y-coordinate changes from positive to negative or negative to positive.

Lastly, we would apply a reflection over the y-axis;

(x, y)     →     (x, -y)

Given:

Perimeter of rectangle = 116 units

let the width be x.

then the length is 5x - 2.

so, Perimeter of rectangle = 116 units

Answer:

The first step in solving this system of equations by elimination method is to eliminate one of the variables by adding or subtracting the two equations.

-9x - 4y = 1

3x + 3y = 3

If we multiply the first equation by 3 and the second equation by -9, we get:

-27x - 12y = 3

-27x - 27y = -27

Now we can add these two equations:

-12y = -24

y = 2

Now we can substitute this value of y back into one of the original equations to find the value of x.

-9x - 4(2) = 1

-9x - 8 = 1

-9x = 9

x = -1

So the solution of this system of equations is (x,y) = (-1,2)

Answer:

You just have to plug in one equation into the other, though you might already know this but the answer would be,
