For function f(x)= -4x²-4x-1,   f(x+h)= -4x² - 8xh - 4h² - 4x - 4h - 1, (f(x+h) - f(x))/h= -8x - 4h - 4

The input values of a function are called the domain, and the output values are called the range. The domain can be any set of values, but each input value must have a unique corresponding output value. If there are multiple input values that produce the same output value, the function is not considered to be well-defined. Functions are used to model a wide range of phenomena in many different fields, including science, engineering, and economics. They are also used in calculus to study rates of change and slopes of curves.

To find f(x+h), we need to replace x with (x+h) in the given function:

f(x+h) = -4(x+h)² - 4(x+h) - 1

= -4(x² + 2xh + h²) - 4x - 4h - 1

= -4x² - 8xh - 4h² - 4x - 4h - 1

To find (f(x+h) - f(x))/h, we first need to find f(x):

f(x) = -4x² - 4x - 1

Then we can substitute f(x+h) and f(x) in the formula:

(f(x+h) - f(x))/h = (-4x² - 8xh - 4h² - 4x - 4h - 1 - (-4x² - 4x - 1))/h

= (-4x² - 8xh - 4h² - 4x - 4h - 1 + 4x^2 + 4x + 1)/h

= (-8xh - 4h² - 4h)/h

= -8x - 4h - 4

So, f(x+h) = -4x² - 8xh - 4h² - 4x - 4h - 1, and (f(x+h) - f(x))/h = -8x - 4h - 4.

Step-by-step explanation:

So how I would think the equation would be would be 108 + x = 173. So how I would solve this is subtracting 108 from both sides to get x = 65. There is most likely a different way to set this up but thats what comes to mind with me.

The height of the parallelogram is 5.4 units.

What is area ?

In mathematics, the area is the measure of the size of a two-dimensional surface or region, usually expressed in square units, such as square inches or square meters. The area of a flat shape or planar figure is the amount of space inside its boundary, or the surface of the object, that is covered by a two-dimensional geometric shape.

One way to find the height is to draw a perpendicular line from point B to line segment AD, forming a right triangle. Let's call the length of this perpendicular line h.

Now we can see that the base of the parallelogram is 10 units (from A to D), and the height is h units (from B to the perpendicular line we drew). The area of the parallelogram is given as 54 units², so we can set up the following equation:

Area = base x height

54 = 10h

Solving for h, we get:

h = 54/10 = 5.4

Therefore,  the height of the parallelogram is 5.4 units.

The required, there is a 20% increase from 55 employees to 66 employees.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,

To calculate the percentage increase from 55 employees to 66 employees, we need to find the difference between the two numbers, divide that difference by the original number, and then multiply by 100 to convert the result to a percentage.

The difference between 66 and 55 is 11.

So, the percentage increase is:

(11/55) x 100% = 20%

The answer of the given question based on the  length in each isosceles right triangle is given below,

An isosceles right triangle is right triangle in which two legs have the same length, making it isosceles triangle, and one of angles is right angle, making it right triangle.  an isosceles right triangle,  two acute angles are congruent, each measuring 45 degrees, and  hypotenuse is equal in length to legs multiplied by √2.

The isosceles right triangle is special case of  45-45-90 triangle, where  angles measure 45 degrees, 45 degrees, and 90 degrees, respectively. In  45-45-90 triangle, the hypotenuse is equal in length to  legs multiplied by √2.

a. If the hypotenuse is 102√, then each leg is the same length as the hypotenuse divided by √2. Therefore:

Leg = 102√/√2 = 102

b. If one leg is 92√, then the hypotenuse is the length of that leg multiplied by √2. Therefore:

Hypotenuse = 92√ * √2 = 92 * 2 = 184.

As a result, the total quilt's area is 512/9 square inches.

Square offers businesses a range of goods and services to help them complete sales deals, use marketing strategies, and control their finances, inventory, and workforce.

The quilt has an 8 x 8 array of square patches, which means it has a total of 8 x 8 = 64 square patches. Each square patch is 2 2/3 inches long.

To find the area of the whole quilt, we need to find the total area covered by all 64 square patches. We can do this by multiplying the length and width of one square patch by the total number of patches:

Area of one square patch = length x width = (2 2/3 in) x (2 2/3 in) = (8/3 in) x (8/3 in) = 64/9 sq in

Total area of all 64 square patches = (64 patches) x (64/9 sq in per patch) = 512/9 sq in

Therefore, the area of the whole quilt is 512/9 square inches.

HI:

Area of rectangle: 8*8= 64

Area of triangle: 4*8=32/2= 16

64+16= 80

Answer: 80ft^2

Answer:

Step-by-step explanation:

Let's call the length of the pen perpendicular to the barn "w", and the length parallel to the barn "l".

The total amount of fencing available is 400 feet. The side against the barn will be of length l, and the other two sides will each be of length w. Therefore, the total length of fencing required is:

l + 2w

This length of fencing must equal 400 feet:

l + 2w = 400

We want to maximize the area of the pen. The area of a rectangle is given by:

A = lw

We can use the equation l + 2w = 400 to solve for l:

l = 400 - 2w

Substituting this expression for l into the equation for the area, we get:

A = w(400 - 2w)

Simplifying:

A = 400w - 2w^2

So the equation to model the area of the pen in terms of w is:

A = 400w - 2w^2

The equation [tex]\sqrt{x} +\sqrt{8}=\sqrt{x+8}[/tex] is an example of the square root property. The square root property states that for any real number a, b, and c, if and only if a + b = c. This property can be used to simplify and solve equations involving square roots.

What does square root mean?

The square root of a number is the number that, when multiplied by itself, produces the original number. For instance, the square root of 16 is 4, because 4 multiplied by itself (4 x 4) equals 16.

The equation [tex]\sqrt{x} +\sqrt{8}=\sqrt{x+8}[/tex] is true because it satisfies the square root property. To see this, note that [tex]\sqrt{x} +\sqrt{8}=\sqrt{x+8}[/tex] implies that x+8=x+8, which is true. Therefore, the equation is true.

To solve for x, we will use the square root property. We know that [tex]\sqrt{x} +\sqrt{8}=\sqrt{x+8}[/tex], so we can rewrite the equation as [tex]\sqrt{x} +\sqrt{8}-\sqrt{x+8}=0[/tex]. We can then use the square root property to simplify the equation to [tex]\sqrt{x} -\sqrt{x}=0[/tex], which implies that x=0. Therefore, the solution to the equation [tex]\sqrt{x} +\sqrt{8}=\sqrt{x+8}[/tex] is x=0.

In conclusion, the equation [tex]\sqrt{x} +\sqrt{8}-\sqrt{x+8}=0[/tex] is an example of the square root property, and the solution to the equation is x=0.

The slope of f(x) = x² - x + 2 at x = 3 is 6.

The limit definition of a derivative is given by:

f'(x) = lim(h->0) [f(x+h) - f(x)] / h

To find the slope of f(x) = x² - x + 2 at x = 3, we need to evaluate this expression at x = 3.

f'(3) = lim(h->0) [f(3+h) - f(3)] / h

f'(3) = lim(h->0) [(3+h)² - (3+h) + 2 - (3² - 3 + 2)] / h

f'(3) = lim(h->0) [(9 + 6h + h² - 3 - h + 2 - 9 + 3 - 2)] / h

f'(3) = lim(h->0) (6h + h²) / h

f'(3) = lim(h->0) (h(6 + h)) / h

f'(3) = lim(h->0) (6 + h)

f'(3) = 6 + 0 = 6
