Distance between two pointsFrom the question, we are to determine the distance between two points.
The given points are (-1, 4) and (5, 4)
Using the formula for calculating the distance between two points
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
From the given information,
x₁ = -1
x₂ = 5
y₁ = 5
y₂ = 4
Put the parameters into the equation
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
d = √[(5 - (-1))² + (4 - 4)²]
d = √[(5 + 1)² + 0²]

Answer:
Step-by-step explanation: The distance between two points can be calculated using the formula:
d = √ ((x2 – x1)² + (y2 – y1)²)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
In this case, the two points are (-1, 4) and (5, 4). Therefore:
d = √ ((5 - (-1))² + (4 - 4)²)
d = √ (6² + 0²)
d = √36
d = 6
Therefore, the distance between (-1, 4) and (5, 4) is 6 units.

Look at the picture for the problem
Please answer both parts
part a and b
a. The equation that represents the given data is y = 700x + 2,000.
b. The average daily attendance at Disneyland on its 80th anniversary is 58,000.
We are given the data about average daily attendance at Disneyland's anniversary celebrations. At Disneyland's 40th anniversary, the average daily attendance was 30,000 people. On the 60th anniversary, the average daily attendance was 44,000 people. We need to create an equation that would represent y, the average daily attendance, based on x, the number of years after Disneyland opened.
We can write the data in the form of points on the coordinate axes. The coordinates of the points are (40, 30,000) and (60, 44,000). We can use the two-point form to write an equation.
(y - y1) = [(y2 - y1)/(x2 - x1)]*(x - x1)
(y - 30,000) = [(44,000 - 30,000)/(60 - 40)]*(x - 40)
(y - 30,000) = [(14,000)/(20)]*(x - 40)
(y - 30,000) = (700)*(x - 40)
y = 700x - 28,000 + 30,000
y = 700x + 2,000
Now, we need to find out the average daily attendance at Disneyland on its 80th anniversary.
y = 700*80 + 2,000
y = 56,000 + 2,000
y = 58,000

Can anyone write the equation of the graph?
The function of the graph is f(x) = |x - 3| + 5
How to find the equation of the graph line?From the question, we have the graph that can be used in our computation:
Given that the graph is an absolute value graph
We start by calculating the vertex of the graph
In this case, the minimum point on the graph is located at the point (3, 5)
This means that
Vertex = (3, 5) i.e. (h, k) = (3, 5)
Recall that the general form of an absolute value function is f(x) = |x - h| + k
Substitute the known values in the above equation
So, we have the following equation
f(x) = |x - 3| + 5
On the graph, we have
(x, f(x)) = (2, 6)
So, we have
6 = a|2 - 3| + 5
This gives
a = 1
So, we have
f(x) = 1 * |x - 3| + 5
Evaluate
f(x) = |x - 3| + 5
Hence, the equation of the graph represented by the figure is f(x) = |x - 3| + 5

The coin is flipped at least 52 times in order to obtain a 99% confidence interval of width of at most . 18 for the probability of flipping a head.
Hence, Option F is correct answer.
In a sample with a number n of people surveyed with a probability of a success of π , and a confidence level of (1-α), we have the following confidence interval of proportions.
[tex]\pi[/tex] ± z[tex]\sqrt{\frac{\pi \p(1-\pi )}{n} }[/tex]
z is the z-score that has a pvalue of [tex]1-\frac{\alpha }{2}[/tex]
Since, the coin is fair, so [tex]\pi =0.5[/tex].
The margin of error is:
[tex]M=z\sqrt{(\frac{\pi (1-\pi )}{n} )}[/tex]
99% confidence level:
So [tex]\alpha =0.01[/tex] ,z is the value of Z that has a p value of 1-[tex]\frac{0.01}{2}[/tex]=0.995,
so Z= 2.575

Given:
Binomial: x² + 10x
To Find:
Constant that should be added to the binomial so that it becomes a perfect square trinomial.Factor the trinomial.Solution:
To find the constant we would compare the binomial with (a + b)² i.e. a² + 2ab + b² as it is the formula for perfect square.
By comparing we get:
a² = x²
2ab = 10x
b² = constant (To find out)
From this we can make out:
a = x
[tex] \therefore[/tex]
[tex] \rm \implies 2 \times x \times b = 10x \\ \\ \rm \implies b = \frac{10x}{2x} \\ \\ \rm \implies b = 5 \\ \\ \therefore \\ \\ \rm \implies {b}^{2} = 25[/tex]
So, constant that should be added to the binomial so that it becomes a perfect square trinomial is [tex] \boxed{\rm 25} [/tex].
Perfect square trinomial is x² + 10x + 25
Factorisation of the trinomial:
[tex] \rm \implies {x}^{2} + 10x + 25 \\ \\ \rm \implies {x}^{2} + 10x + {5}^{2} \\ \\ \rm \implies {x}^{2} + 5x + 5x + {5}^{2} \\ \\ \rm \implies x(x + 5) + 5(x + 5) \\ \\ \rm \implies (x + 5)(x + 5) \\ \\ \rm \implies {(x + 5)}^{2} [/tex]
a point is randomly picked from inside the rectangle with vertices , , , and . what is the probability that ?
The probability that x < y is 1/8 or 0.25 .
What is probability of an event?
The possibility or chance of an event happening is commonly believed to be the probability of it happening. In the most basic scenarios, the probability that a specific event 'A' will occur as a result of an experiment is calculated by dividing the number of ways that 'A' can happen by the total number of possible outcomes.
P(A) = Number of events concerning 'A' / Total events in consideration.
Given, the vertices of the rectangle are (0, 0), (4, 0), (4, 1), (0, 1).
On carefully analyzing and plotting the vertices roughly, we get that the given rectangle has a width of 4 units and a height of 1 unit.
Therefore, the area of the given rectangle = Width*Height = 4*1 = 4 units²
Also, it can be assessed that the line x = y passes through the points of the rectangle at (0, 0) and (1, 1).
Thus, the area for which x < y will be an isosceles triangle with side length of 1 units and co-ordinates of vertices as (0, 0), (0, 1) and (1, 1).
The area of the isosceles triangle thus assumed = 0.5 × 1² = 0.5 units²
Probability that x < y is P(E): 0.5/4 = 1/8 = 0.25

What is Pythagoras theorem?
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse.
Main Body:
according to the question --
hypotenuse = 52 in
base = 42 in
height =?
Pythagoras theorem = [tex]{P^{2} +B^{2} }[/tex] = [tex]H^{2}[/tex]
inserting the values --
52² = 42² +H²
H² = 2704- 1764
H² = 940
H≈31 inches
Hence the height of TV is 31 inches

Question 1 of 10
Which of the following is the solution to | x1-2 ≤-3?
O A. All values are solutions
OB. xs-1 and x 25
OC. xs-1
OD. No solution
x = -1 is the solution to the given inequality |x| - 2 ≤ -3.
The five steps to resolving inequalities are as follows?
When addressing an inequality, we can:
Equal numbers are added to both sides.Take the same amount away from both sides.Add the same positive number to both sides.Subtract the same positive value from both sides.Reverse the sign and multiply both sides by the same negative value.Isolate the variable on one side of the inequality and place all other constants on the other. To achieve this, alter the inequality by performing opposing procedures. First, multiply each side by two to isolate the x. Any action you take toward one side must also be taken toward the other.
C) If x = -1,
|x| - 2 ≤ -3
|-1| - 2 ≤ -3.
1 - 2 ≤ -3.
-1 ≤ -3 which is true.
Hence, x = -1 is the solution to the given inequality |x| - 2 ≤ -3.

The largest U.S. flag in the world is 225 feet by 505 feet.
------------------------
If a square yard of the flag weighs about 3.8 ounces, how much does the entire flag weigh in pounds?
The weight of the U.S. flag in pounds is 2,998.44 pounds.
What is the weight of the flag?The dimension of the U.S. flag is in feet. The dimensions have to be converted to yards.
1 foot = 1/3 yards
225 / 3 = 75 yards
505 / 3= 168.33 yards
The next step is to determine the area of the U.S. flag.
Area = length x width
75 x 168.33 = 12,625 yards²
Weight of the U.S. flag in ounces = 12,625 yards² x 3.8 = 47,975 ounces
1 ounce = 1/16 pounds
Weight of the U.S. flag in pounds = 47,975 / 16 = 2,998.44 pounds

Use the remainder theorem to find P(-1) for P(x) = −x³ – 2x² −9. Specifically, give the quotient and the remainder for the associated division and the value of P(-1).
Using remainder theorem, Quotient = x-9 and Remainder = x² - x.
According to the remainder theorem, the remainder equals f when a polynomial, p(x), is divided by (x - a) (a). Euclid's Division Lemma can be used to demonstrate this. Using this, p(x) = q(x) (x - a) + r, where q(x) is the quotient and 'r' is the remainder.Remainder Theorem is a method for dividing polynomials according to Euclidean geometry. This theorem states that when a polynomial P(x) is divided by a factor (x - a), which isn't really an element of the polynomial, a smaller polynomial is produced along with a remainder.P(x) = −x³ – 2x² −9
P(-1) = −(-1)³ – (-1)x² −9
P(-1) = −(-1) – 2(1) −9
= 1 -2 -9
= -10
Remainder of P(-1) = −(-1)³ – (-1)x² −9 is -10.
Remainder of P(x+1)
= −x³ – 2x² −9 / x+1
Quotient = x-9 and Remainder = x² - x
Hence, using remainder theorem, Quotient = x-9 and Remainder = x² - x.
