The flight time from Athens to Berlin is 50 minutes as per the given data.
What is local time?Local time refers to the time in a specific location or time zone. It is the time that is used and observed by people in a particular region or city.
To find the flight time from Athens to Berlin, we need to calculate the time difference between the two cities and subtract it from the elapsed time between the departure and arrival times.
Athens is one hour ahead of Berlin when it is 9:00 AM in Athens, it is 8:00 AM in Berlin. This means that when the plane leaves Athens at 13:15 local time, it is 12:15 in Berlin.
The elapsed time between the departure time (13:15) and the arrival time (15:05) is 1 hour and 50 minutes.
However, we need to account for the time difference between the two cities. Since Berlin is one hour behind Athens, we need to subtract one hour from the elapsed time:
1 hour and 50 minutes - 1 hour = 50 minutes
Therefore, the flight time from Athens to Berlin is 50 minutes.

(x -h)² +(y -k)² = r²r(h, k)Step-by-step explanation:
You are being asked for the equation of a circle, and a description of what it is.
Points equidistantThe distance equation tells you that the distance of (x, y) from (h, k) is ...
d = √((x -h)² +(y -k)²)
If this distance is r, the radical can be removed, and we can write the equation as ...
(x -h)² +(y -k)² = r² . . . . formula for P(x, y)
DescriptionThis is a circle of radius r, with a center at (x, y) = (h, k).
The equation of a circle of radius r with center at (x, y) = (x -h)² +(y -k)² = r².
Given that, P(x, y) is a distance r>0 from a fixed point C(h, k).
What is a circle equation?The equation of circle provides an algebraic way to describe a circle, given the center and the length of the radius of a circle. The equation of a circle is different from the formulas that are used to calculate the area or the circumference of a circle.
The standard equation of a circle with center at (x1,y1) and radius r is (x-x1)²+(y-y1)²=r²
Using distance formula,
The distance between (x, y) from (h, k) is
d = √((x -h)² +(y -k)²)
If this distance is r, then we get
(x -h)² +(y -k)² = r²
Hence, the equation of a circle of radius r with center at (x, y) = (x -h)² +(y -k)² = r².

Then find the area of the new patio if the original patio measures 13 feet by 13 feet.
Explanation:
Ezra has a square brick patio where x represents the length of one side of this square patio:
And hee wants to reduce the width by 6 feet, and increase the length by 6 feet.
The new width is x-6,
The new length is x+6.
[tex]\begin{gathered} Expressions\text{ for the length and the width of the new patio:} \\ l=x+6 \\ w=x-6 \end{gathered}[/tex]Then, we need to find the area of the new patio:
[tex]A=lw[/tex]We multiply the length by the width. The area is:
[tex]lw=(x+6)(x-6)[/tex]And finally, if the original measure of the sides is x=13 ft, the area of the new patio is:
[tex]\begin{gathered} (x+6)(x-6) \\ \downarrow \\ (13+6)(13-6) \\ \downarrow \\ (19)(7) \\ \downarrow \\ 133 \end{gathered}[/tex]Since it represents the area the units are square feet:

ANSWER:
18.1 ft³
STEP-BY-STEP EXPLANATION:
Given:
Radius (r) = 1.2 ft
Height (h) = 4 ft
We can determine the volume of the cylindrical barrel using the following formula:
[tex]V=\pi\cdot r^2\cdot h[/tex]We substitute each value and calculate the volume, like this:
[tex]\begin{gathered} V=\left(3.14\right)\left(1.2^2\right)\left(4\right) \\ \\ V=18.1\text{ ft}^3 \end{gathered}[/tex]The volume of the barrel is 18.1 ft³
in a table that shows no exact solutions, how do you know if there are any solutions? How can you find an approximate solution?
If we have a quadratic equation described in a table and it does not show the exact solution (roots) of the equation, we can look if, with the values of x or the independent variable sorted, we have a change of sign.
This indicates that there is a root between those two values of x.
For example:
x = 2 --> f(x) = -3
x = 3 --> f(x) = 4
We can see that from x=2 to x=3, we have a sign change. Then we know that, because of the continuity of the quadratic function, we must have a value between x=2 and x=3 for which f(x)=0. This is an application of the Intermediate Value Theorem.
We can then approximate the value of the root x=r as the average between x=2 and x=3. This is the bisection method to find roots of functions. In this case, it would give a result r=2.5.
There are other methods (Newton-Raphson or False position, for example), but this bisection method is the simplest approximation.
Given Point A, what is the coordinate for A' after the following transformation has occurred?(x, y) + (x – 5, -y + 2)A (5, 7)
So we have the point A=(5,7) and the following transformation:
[tex](x,y)\rightarrow(x-5,-y+2)[/tex]Transformations take a point as input and return another point that usually is different than the one used as input. Since our input is (5,7) then we just need to replace 5 and 7 in place of x and y on the transformation:
[tex]\begin{gathered} A^{\prime}=(x-5,-y+2)=(5-5,-7+2)=(0,-5) \\ A^{\prime}=(0,-5) \end{gathered}[/tex]Then, the point we are looking for is A'=(0,-5).
An open topped box can be created by cutting congruent squares from each of the four corners of a piece of cardboard that has dimensions of 30 cm by 40 cm and folding up the sides. Determine the dimensions of the squares that must be cut to create a box with volume of 2448cm^3.
Let's start by drawing the situation:
According to this, one of the dimensions of the box is 40-2x. The other one is 30-2x and the last one, that we could say it's the height, is x.
The volume of a box is given by the product of the three dimensions:
[tex]\begin{gathered} V=(40-2x)\cdot(30-2x)\cdot x \\ V=(1200-80x-60x+4x^2)\cdot x \\ V=1200x-140x^2+4x^3 \end{gathered}[/tex]Use the given value of the volume to find x:
[tex]\begin{gathered} 2448=1200x-140x^2+4x^3 \\ 4x^3-140x^2+1200x-2448=0 \end{gathered}[/tex]Factoring this expression we have that:
[tex]\begin{gathered} 4(x-3)(x^2-32x+204)=0 \\ x-3=0 \\ x=3 \end{gathered}[/tex]One of the possible dimensions of the square is 3. Now, solve the quadratic expression (third factor) to find the other 2 options:
[tex]\begin{gathered} x^2-32x+204=0 \\ x=\frac{-(-32)\pm\sqrt[]{(-32)^2-4(1\cdot204)}}{2\cdot1} \\ x=\frac{32\pm\sqrt[]{1024-816}}{2} \\ x=\frac{32\pm\sqrt[]{208}}{2} \\ x1=\frac{32+\sqrt[]{208}}{2} \\ x2=\frac{32-\sqrt[]{208}}{2} \end{gathered}[/tex]It means that the squares can have 3 different dimensions, which are:
[tex]3,\frac{32+\sqrt[]{208}}{2},\frac{32-\sqrt[]{208}}{2}[/tex]Nevertheless, the second possible option is not coherent since it's value is close to 23 and the dimensions of the cardboard are 30 and 40. It means that the possible dimensions are 3 and (32-sqrt(208))/2.

The combined triangles will look as shown below:
It can be observed that the lengths of the three sides fit alongside one another perfectly. This means that the lengths are equal.
Also, the middle piece of the three triangles has no space when it aligns with the other two triangles. This means that all the angles add up to 180°.It would also be a safe assumption that the angles are equal to each other, therefore the measure of each angle will be:

Hello there. To solve this question, we'll simply have to make x => x + 5 in the function.
Given the function:
[tex]f(x)=4x^2-3^{}[/tex]We have to determine f(x + 5)
By making x => x + 5 in this function, we get:
[tex]f(x+5)=4\cdot(x+5)^2-3[/tex]Now remember the binomial expansion of order 2:
[tex](a+b)^2=a^2+2ab+b^2[/tex]Therefore we have:
[tex]f(x+5)=4\cdot(x^2+2\cdot x\cdot5+5^2)-3[/tex]Multiply the terms inside parentheses and calculate the square.
[tex]f(x+5)=4\cdot(x^2_{}+10x+25)-3[/tex]Apply the distributive property
[tex]f(x+5)=4x^2+4\cdot10x+4\cdot25-3[/tex]Multiply and add the numbers
[tex]\begin{gathered} f(x+5)=4x^2+40x+100-3 \\ \boxed{f(x+5)=4x^2+40x+97} \end{gathered}[/tex]This is the answer we're looking for.
A way of showing this is the correct answer is to make x = 1 and x = 6 in the former function:
[tex]\begin{gathered} f(1)=4\cdot1^2-3=4\cdot1-3=4-3=1 \\ f(6)=4\cdot6^2-3=4\cdot36-3=144-3=141 \end{gathered}[/tex]Then making x = 1 in the expression we found after:
[tex]f(1+5)=f(6)=4\cdot1^2+40\cdot1+97=4+40+97=141[/tex]As expected.
1. Find the domain and range of f(x) = sqrt(x)2. Find the domain and range of f(x) = 3x + 2
We have the function:
[tex]f(x)=\sqrt[]{x}[/tex]The domain is the set of values of x for which f(x) is defined. In this case, f(x) is defined only for non-negative values of x, so the domain is D:{x≥0}.
The range is the set of values that f(x) can take for the domain in which it is defined. In this case, f(x) will only take non-negative values, so the range can be defined as R: {y≥0}.
For the linear function f(x) = 3x+2, we don't have restrictions for the domain and the the range: both x and y can take any real value, so the domain and range are D: {x: all real numbers} and R: {y: all real numbers}.
Answer:
For the function f(x) = √x, the domain is D:{x≥0} and the range is R: {y≥0}.
For the function f(x) 3x+2, the domain is D: {x: all real numbers} and the range is R: {y: all real numbers}.

[tex]\begin{gathered} 2\cdot(782-2y)+y=787 \\ \\ 1564-4y+y=787 \\ \\ -3y=787-1564 \\ \\ y=\frac{-777}{-3} \\ \\ y=259 \\ \\ \text{ Now, for x:} \\ \\ x=782-2y \\ \\ x=782-2\cdot259 \\ \\ x=782-518 \\ \\ x=264 \end{gathered}[/tex]Therefore:
Candy bar A contains 264 calories and candy bar B contains 259 calories
Solve for y.y+3/9=4/5
As per given by the question,
There are given that;
[tex]\frac{y-3}{9}=\frac{4}{5}[/tex]Now,
Solve the given equation for the value of y.
So,
The given equation can be written as,
[tex]\frac{y-3}{9}-\frac{4}{5}=0[/tex]Then,
[tex]\begin{gathered} \frac{5(y-3)-36}{45}=0 \\ 5y-15-36=0 \\ 5y-51=0 \\ 5y=51 \end{gathered}[/tex]So,
[tex]y=\frac{51}{5}[/tex]Hence, the value of y is;
[tex]\frac{51}{5}[/tex]
