Length of third side = 10 units.

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.

Here, given that,

Height = 7 units

Base = √51 units

And, we have, it is a right angle triangle  

and we have to find the hypotenuse.

By Pythagorean theorem we get,

Hypotenuse = √7²+ 51

                     =√100

                     =10 units.

Hence, Length of third side = 10 units.

The angles in the triangle is as follows:

A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.

Therefore, let's find the angles a, b and c in the triangle as follows:

c + 44 + 53 = 180(sum of angles in a triangle)

c = 180 - 44 - 53

c = 83 degrees

Therefore, let's find the value of a and b.

b + 83 = 180 (sum of angle on straight)

b = 180 - 83

b = 97 degrees.

Hence,

28 + 97 + a = 180(sum of angles in a triangle)

a = 180 - 28 - 97

a = 55 degrees.

Therefore,

The values for the inequality in vertex form is y < -1.5(x - 1)^2 + 4.5

The equation for a parabolic function in vertex form is given by y = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.

The vertex of the parabolic path of the drinking fountain is (1, 4.5). So, h = 1 and k = 4.5.

Substituting the values for h and k into the equation:

y = a(x - 1)^2 + 4.5

Now, we need to determine the value of a using the point

(x, y) = (2, 4)

So, we have

a(2 - 1)^2 + 4.5 = 4

Evaluate

a = -1.5

So, we have

y = -1.5(x - 1)^2 + 4.5

The range of values for the correlation coefficient is - 1 to 1, inclusive is the correct answer.

Value is an important concept in economics, philosophy, and psychology. In economics, value is the amount of utility or satisfaction that an individual derives from a good or service. In philosophy, value is the worth or usefulness of something, based on its purpose. In psychology, value is the perceived importance of something that influences an individual's behavior. Value can also be seen as a measure of the worth of an object or action. Value is subjective and can differ from one person to another, depending on their beliefs and experiences. Value is also a key factor in decision-making and can help individuals make informed choices.

The range of values for the correlation coefficient is -1 to 1, inclusive. This means that the correlation coefficient can range from a perfect negative correlation (-1) to a perfect positive correlation (1).

The system of equations are  y₁ = 16x₁ + 5  and  y₂ = 17x₂  respectively

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first equation be represented as A

Now , the value of A is

The first restaurant charges a delivery fee of $5 for the entire purchase and $16 per pizza

So , y₁ = 16x₁ + 5

where x is the number of pizzas and y is the total charge

Let the second equation be represented as B

And , The second restaurant has no delivery fee and charges $17 per pizza

So , y₂ = 17x₂

Now , Total charge from the first restaurant (in dollars) is given by the equation , y₁ = 16x₁ + 5  where x₁ is the number of pizzas

And , Total charge from the second restaurant (in dollars) is given by the equation , y₂ = 17x₂  where x₂ is the number of pizzas

For the total charge to be same for each restaurant , y₁ = y₂

Substituting the values in the equation , we get

16x₁ + 5 = 17x₂

And , when x₁ = x₂

16x₁ + 5 = 17x₁

Subtracting 16x₁ on both sides of the equation , we get

x₁ = 5

So , the total charge would be same if the number of pizzas from the first restaurant is 5

Hence , the system of equations are solved

8. The range of the function is (-2.5,∞).

9. The value of f(-5) is 0.

10. The value of f(1) is 2.5.

What is increasing interval?

The interval is expanding if the value of the function f(x) grows as the value of x increases, and it is contracting if f(x) shrinks as x shrinks.

The graph is increasing in between points (-5.5,-2.5) to (-5,0), (-4,-2)to (-3,2.5) and (2,0) to (∞,∞)

The increasing interval is (-5.5,-5)∪(-4, -3)∪ (2,∞).

The graph is decreasing (-5,0 to (-4,2) and (1,2.5) to (2,0).

The decreasing interval of the function is (-5,-4)∪(1,2).

If the value of x for which the value of f(x) is negative, the interval is known as the negative interval.

From the point (-5.5, -2.5) to (-3.25,0), the graph lies below x-axis.

Thus the negative interval is (-5.5, -3.25).

If the value of x for which the value of f(x) is positive, the interval is known as the positive interval.

From the point (-3.25,0) to (∞,∞), the graph lies above x-axis.

Thus the negative interval is (-3.25,∞).

The graph of a function y = f(x) has a local maximum at the point where the graph changes from increasing to decreasing. At this point the tangent has zero slopes. At the point when the graph shifts from declining to increasing, a local minimum is present.

The minimum is at (-4,-2) and (2,0).

The maxima are at (-5,0).

The possible value of the x-coordinates of the graph is the domain of the graph.

The domain of the graph is (-5.5,∞).

The possible value of the y-coordinates of the graph is the range of the graph.

The range of the graph is (-2.5,∞).

The y-coordinate of a point at x = a on the graph is the value of f(a).

(-5,0) is a point on the graph. Thus the value of f(-5) is 0.

(1,2.5) is a point on the graph. Thus the value of f(1) is 2.5.

After solving, the farmer have total 21 chicken and 19 cows.

In the given question, a farm raises cows and chickens.

The farmer has a total of 40 animals.

One day he counts the legs of all his animals and realizes he has a total of 118 legs.

We have to find how many chickens the farmer have.

Let the number of cows that the farmer have is x.

Let the number of chicken that the farmer have is y.

The farmer has a total of 40 animals.

So the equation should be

x + y = 40....................(1)

As we know that a cow has 4 legs and a chicken has 2 legs.

He has a total of 118 legs.

Now the equation should be

4x + 2y = 118....................(1)

Substituting x = 40 - y from the equation 1, we get

4(40 - y) + 2y = 118

160 - 4y + 2y = 118

160 - 2y = 118

Subtract 160 on both side, we get

-2y = - 42

Divide by -2 on both side, we get

y = 21

Now putting the value of y in x = 40 - y, we get

x = 40 - 21

x = 19

Hence, the farmer have total 21 chicken and 19 cows.

The farmer has 0 chickens and 40 cows.

Let's solve this problem using an algebraic equation. First, we will assign a variable to represent the number of chickens the farmer has. We will call this variable 'x'. We also know that the total number of animals the farmer has is 40. Therefore, we can write an equation that states:

x + (40 - x) = 40

This equation states that the sum of the number of chickens and the number of cows is equal to the total number of animals the farmer has. Now, let's look at the number of legs the animals have. We know the total number of legs is 118. We also know that chickens have two legs and cows have four legs. We can now write another equation that states:

2x + (4(40 - x)) = 118

This equation states that the sum of the number of chicken legs and the number of cow legs is equal to the total number of legs the animals have. We can solve for x by multiplying both sides of the equation by -1 and then adding both equations:

2x + (4(40 - x)) = 118

-2x - (4(40 - x)) = -118

0x = -118 + 118

0x = 0

Since 0x = 0, we can conclude that x = 0. This means that the farmer has 0 chickens and 40 cows.
