What does 4 mean in maths?

Answer:

(x + 2)^2 + (y + 5)^2 = 1

Step-by-step explanation:

Since this circle is centered at (-2, -5), we have to add values within the squares. The standard form of a circle equation is:

(x - h)^2 + (y - k)^2 = r^2

So -2 is h and -5 is k. Substituting that in we get:

(x + 2)^2 + (y + 5)^2 = r^2

We are given the radius is 1, and one squared is one, so the final equation is:

(x + 2)^2 + (y + 5)^2 = 1

Answer:

C = 0.06x + 0.45

Step-by-step explanation:

Today is 2023

So, from 2016 to 2023, it has been 7 years.

0.85 - 0.45 = $0.40

So, $0.40 is the increase in 7 years

0.40 / 7 = $0.06

So, $0.06 is the change per year

Let C represent the total cost and x represent the number of years and we have

C= 0.06x + 0.45

Joshua will need 7 additional customers.

The parameters that will help us to determine the number of customers is give as follows:

Joshua's goal is to sell more than 20 items at a farmers' market. So far, he has sold 6 items. Each customer buys 2 items.

Since Joshua's goal is to sell more than 20 items at a farmers' market and he has sold 6 items. and If each of his customers buys 2 items, the number of additional customers needed will be:

= (20 - 6) / 2

This is given as  14 / 2

The the number of customers needed = 7

In conclusion He will  need 7 additional customers.

H) {8, 9, 10, 11, 12}

Step-by-step explanation:

The domain of a problem is the set of all possible values that can be the input of a given function. In this case, the problem asks for the number of volleyball players are on a team. Since one cannot have a fraction of a person, then the domain must be a set of whole numbers. Moreover, the problem gives one the information that there has to be at least (8) players, and no more than (12). Thus, the only option that satisfies all of these requirements is option (H). Therefore the correction option is the following,

The parameters of the exponential function are given as follows:

An exponential function is defined as follows:

y = a(b)^x.

For which the parameters are given as follows:

When he first started monitoring the population, there were about 1,550 bluefin tuna in the bay, meaning that the parameter a is given as follows:

a = 1550.

One year later, he estimated that the population of bluefin tuna had decreased to about 1,488, hence the parameter b is obtained as follows:

b = 1488/1550 = 0.96.

Hence the function is defined as follows:

y = 1550(0.96)^x.

Answer:

the correct answer is 9²

Answer:

9

Step-by-step explanation:

It is stating that 81 is equal to x², in which the variable x stands for a number.

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x, by rooting both sides:

√x² = √81

x = √81 = √(9 * 9) = 9

9 is your missing base.

An example that contradicts this definition would be an ellipse that set all points such that the sum of the distances between the point and two other fixed points (called foci) is constant.

The equation of a circle with center (h,k) and radius r is :

r² = (x−h)² + (y−k)²

A circle is defined as the set of all points that are the same distance from one given point, called the center of the circle. An example that contradicts this definition would be an ellipse, which is defined as the set of all points such that the sum of the distances between the point and two other fixed points (called foci) is constant.

An ellipse is not a circle since all points of an ellipse are not equidistant to the center point

To make the definition more accurate, it could be modified to say "A circle is defined as the set of all points that are a fixed distance from one given point, called the center of the circle." or "A circle is defined as the set of all points such that the distance between the point and the center is constant"

In addition to describing a character's appearance and movement on stage, stage directions also describe the sound and visual effects of the surroundings.

Stage directions may include phrases like "Katy enters the room" and "The man deals a deck of cards." They describe what the characters in the scene are doing.

Stage direction is also evident in statements about the setting, like "the early sunlight floods the space." The stage directions specify how a character will look, where they will move on the stage, and how the surroundings will sound and seem.

The links between things, characters, and locations in a book are made clear to the reader by stage directions, which also provide important details about the action. Stage directions are given by actors on the stage. "Stage right" is the area to the audience's left.

Answer:

x = 4√7

Step-by-step explanation:

You can use the pythagorean theorem which is a² + b² = c²

The farmer should expect to harvest 17,500 pounds of spinach from the field.

What is a function?

A function is a mathematical relation between a set of inputs (called the domain) and a set of possible outputs (called the range). The inputs are usually denoted by variables and the outputs are usually denoted by the value of a function. A function assigns exactly one output to each input.

In the given problem, g(z) = 400z - z^2 is a function that describes the area of a field in square feet, where z represents the width of the field in feet.

Given that the width of the field is 50 feet, we can substitute this value into the function to find the area of the field:

g(50) = 400(50) - 50^2 = 20,000 - 2,500 = 17,500 square feet

We know that the farmer will plant spinach in this field and expect to harvest 1 pound of spinach per square foot. Therefore, the total number of pounds of spinach the farmer should expect to harvest from the field is:

1 pound/square foot * 17,500 square feet = 17,500 pounds

Hence, the farmer should expect to harvest 17,500 pounds of spinach from the field.
