Step-by-step explanation:
Let's find the distance between your two points.
(−5,5);(−2,3)
(x1,y1)=(−5,5)
(x2,y2)=(−2,3)
Use the distance formula:
D=√(x2−x1\()^{2}\)+(y2−y1\()^{2}\)
=√(−2−−5\()^{2}\)+(3−5\()^{2}\)

The volume of the container is 2,452,864 cubic feet.
What is a prism?A prism is a three-dimensional object.
There are triangular prism and rectangular prism.
We have,
The volume of a rectangular prism can be found by multiplying the length, width, and height of the prism.
We know that the container can hold 896 wooden cube blocks, each with an edge length of 14 ft.
This means that the total volume of the wooden blocks is:
V(block) = (14 ft)³ = 2,744 ft^3
To find the volume of the container, we need to divide the total volume of the wooden blocks by the number of blocks that can fit in the container.
We are told that the container can hold 896 wooden blocks, so we can set up the following equation:
V(container) / V(block) = 896
Solving for V(container):
V(container) = V(block) x 896
V(container) = 2,744 ft³ x 896
V(container) = 2,452,864 ft³
Therefore,
The volume of the container is 2,452,864 cubic feet.

If you flip three coins, the probability of getting three heads is 0.125. Which of the following statements follows from this?
answer choices
O If you flip three coins 1000 times, you will get three heads exactly 125 times.
O If you flip 3 coins 10 times and never get three heads, the probability of getting three heads in the next set of 10 flips is slightly greater than 0.125.
O If you have 20 sets of three coin flips, then at least one set of flips will be three heads.
O If you flip 3 coins 5000 times, the percentage of time you get three heads will be very close 12.5%.
O If you get 3 heads two times in a row, the probability of getting 3 heads again on the next toss of 3 coins is nearly zero.
Answers
Using the given provided probability value of getting three heads, The statement which best follow the given condition is If you flip 3 coins 5000 times, the percentage of time you get three heads will be very close to 12.5%.
What do you mean by probability?
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
According to the given question:
Assume you have a fair coin, which means it will likely land tails up 50% of the time and heads up 50% of the time. Let's say you flip it three times, each time independently. What is the likelihood that it will land heads up first, followed by a tails up landing?
The solution is 1/8, or 12.5%.
coin flipped = 3 times.
probability of getting three heads = 0.125
Since, This probability explains the chances of landing three heads which is 0.125 which in terms of percentage is 12.5% .
So, The statement is If you flip 3 coins 5000 times, the percentage of time you get three heads will be very close 12.5%.

Determine the domain and range of the following parabola. f(x)=−3x2−30x−74
Answers
Step-by-step explanation:
1. if to rewrite the given equation, then
y= -3(x+5)²+1;
2. the vertex of the parabola is (-5;1) and it is the highest point. Then
3. domain: x is any value, x∈(-∞;+∞);
range: y not greater than 1, y∈(-∞;1].
For the parabola f(x) = -3x² - 30x - 74, the domain is all real numbers (-∞, ∞), and the range is also all real numbers (-∞, ∞).
To determine the domain and range of the given parabola f(x) = -3x² - 30x - 74, we need to understand the behavior of parabolas.
The domain of a function represents all the possible x-values for which the function is defined. In this case, there are no restrictions on the x-values for the given quadratic function. Therefore, the domain is all real numbers, expressed as (-∞, ∞).
The range of a function represents all the possible y-values that the function can produce. For a parabola, if the coefficient of the squared term (in this case, -3) is negative, the parabola opens downward. Since the coefficient is negative, the parabola will have a maximum value. In this example, there is no minimum or maximum specified; thus, the range will also be all real numbers.

Consider the following expression:- 5x² - 6x²Step 2 of 2: Determine the degree and the leading coefficient of the polynomial.
Answers
Hello!
We have the expression below:
\(-5x^2-6x^2\)First, notice that we can simplify it as a monomial, right? So, let's do it:
\(-5x^2-6x^2=-11x^2\)Now, we obtained the monomial below:
-11x²
Let's analyze it and solve your question:The leading coefficient will be the number that accompanies the variable with the highest exponent. In this case, we have only one term, so the leading coefficient is -11.
The degree is the highest power that appears in the polynomial. So, the degree is 2 because it's raised two.

Answers
Answer:
a) 676, 1296
b) 17576, 46656
c) 456976, 1679616
Step-by-step explanation:
firstly we know that there are 26 letters in the alphabet.
there are 26 ways of choosing the first character and 26 ways choosing the second character,
Therefore, the possible number of domains with two leeter is;
n = 26²
= 26 × 26
= 676
now when the digits are allowed, there are 26 + 10 = 36 characters to be used in total
therefore the possible number of domains with two characters is;
n = 36²
= 36 × 36
= 1296
b)
there are 26 ways of choosing each character
therefore, the possible number of domains with three letters is
n = 26³
= 26 × 26 × 26
= 17576
when the digits are allowed, there are 26 + 10 = 36 characters to be used in total
therefore , the possible number of domains with three characters is;
n = 36³
= 36 × 36 × 36
= 46656
c)
there are 26 ways of choosing each character, therefore the possible number of domains with four letters is;
n = 26⁴
n = 26 × 26 × 26 × 26
n = 456976
when the digits are allowed, there are 26 + 10 = 36 characters to be used in total
therefore, the possible number of domains with four characters is;
n = 36⁴
n = 36 × 36 × 36 × 36
= 1679616
There are 676 domain names consisting of just two letters in a sequence that can be formed.
There are 1296 domain names of length two are there if digits, as well as letters, are per-mitted as characters.
There are 17576 domain names are there consisting of three letters in sequence.
There are 46656 of this length are there if either letters or digits are permitted.
GivenAs of April 2006, roughly 50 million web domain names were registered.
1. How many domain names consisting of just two letters in sequence can be formed?
There are 26 letters in the English alphabet.
Combining 2 domain names with letters alone will be;
\(\rm =n^2\\\\ = 26^2\\\\ =26 \times 26\\\\=676\)
2. How many domain names of length two are there if digits, as well as letters, are per-mitted as characters.
If digits are allowed with letters:
There are 10 digits from 0-9.
Therefore 26 letters + 10 digits = 36
\(\rm = n^2 \\\\= 36^2 \\\\ = 36 \times 36 \\\\ = 1296\)
3. How many domain names are there consisting of three letters in sequence?
There are 26 ways of choosing each character;
Therefore, the possible number of domains with three letters is;
\(= \rm n^3\\\\= 26^3\\\\= 26 \times 26 \times 26\\\\= 17576\)
4. How many of this length are there if either letters or digits are permitted?
The digits are allowed, there are 26 + 10 = 36 characters to be used in total
Therefore, the possible number of domains with three characters is;
\(\rm = n^3 \\\\= 36^3 \\\\ = 36 \times 36 \times 36\\\\ = 46656\)

A perimeter is a closed route that covers, surrounds, or outlines a two-dimensional form or length. The circumference of a circle or an ellipse is its perimeter. There are various practical applications for calculating the perimeter.
Solution:
Perimeter of Rectangle = 2*(Length + Breadth)
According to the question
Breadth = 3*Length

A hat contains 35 marbles. Of them, 20 are red and 15 are green. If one marble is randomly selected out of this hat, what is the probability that this marble is red? Round your answer to two decimal places. P(A) =
Answers
Answer:
P(A) = 0.57 (rounded to two decimal places).
Step-by-step explanation:
The probability of selecting a red marble from the hat can be found by dividing the number of red marbles by the total number of marbles:
P(red) = number of red marbles / total number of marbles
P(red) = 20/35
We can simplify this fraction by dividing both the numerator and denominator by 5:
P(red) = 4/7
So the probability of selecting a red marble from the hat is 4/7, or approximately 0.57 when rounded to two decimal places.
Therefore, P(A) = 0.57 (rounded to two decimal places).
