Potential Energy = 10J

Step-by-step explanation:

mass of the book = 1.0kg

height = (0.5 + 1)m

acceleration due to gravity = 10m/s²

Potential Energy = mass × acceleration × height

Potential Energy = 1kg × 10m/s² × 1m

Potential Energy = 10J

The number of fewer people living in Todsham in 6 years compared with now, found using the formula for population growth rate, is about 79,500 people

The formula for finding the population of a town after a specified number of years, where the rate of change of the population, and the number of people in the town are known can be presented as follows;

P = A·(1 - r)ˣ

Where;

P = The current population of the town = The population after the indicated duration

A = The initial population of the town = 300,000

r = The population growth rate = 5%

The population after 6 years is therefore;

P = 300,000 × (1 - 0.05)⁶ ≈ 220,527

The number of fewer people living in Todsam in 6 years = 300,000 - 220,527 = 79473 ≈ 79,500

Thus, the vertices of the larger square have the following coordinates: (-6, 7),  (1, 7),(1, 0), and  (-6 ,0).

The ratio of the scale of an original thing to a new object that is a representation of it but of a variable size is known as a scale factor (bigger or smaller).

The procedures below can be used to increase form A by a scale factor of 3.5 with the centre of enlargement at (8,-7).

Transform the square so that its origin is where the centre of enlargement is (0,0).

To do this, we deduct each vertex's coordinates from the centre of enlargement (8,-7):

A = (4 - 8, -3+ 7) = (-4, 4)

B = (6 -8, -3 + 7) = (-2, 4)

C = (6 - 8, -5 + 7) = (-2, 2)

D = (4 - 8, -5 + 7) = (-4, 2)

Multiply the coordinates of the each vertex by the scaling factor (3.5) to enlarge the translated square:

A = (-14, 14)

B = (-7, 14)

C = (-7, 7)

D = (-14, 7)

By adding those coordinates of the centre of the enlargement (8,-7) to each vertex, move the square from its larger state back to its original one:

A = (-14 + 8, 14-7) = (-6, 7)

B = (-7 + 8, 14-7) = (1, 7)

C = (-7 + 8, 7-7) = (1, 0)

D = (-14 + 8, 7-7) = (-6 ,0)

As a result, the vertices of the larger square have the following coordinates: (-6, 7),  (1, 7),(1, 0), and  (-6 ,0).

Main Answer: The inverse of the given function f(x) = x7/(x-3) is f^-1(x) = 3x/(x-7). The domain of f is {x|x ≠ 3} and the range of f is {y|y ≠ 7}. The domain of f^-1 is {y|y ≠ 7} and the range of f^-1 is {x|x ≠ 3}.

Supporting Explanation:

To find the inverse of the given function f(x) = x7/(x-3), we need to first replace f(x) with y. So, we have y = x7/(x-3). Next, we need to swap x and y and solve for y. This gives us x = y7/(y-3). Now, we need to solve this equation for y.

Multiplying both sides by y-3, we get xy-3 = y7. Expanding this, we get xy - 3x = y7. Bringing all the y terms to one side and x terms to the other side, we get y7 + 3y - 3x = 0. This is a seventh-degree polynomial equation that can be solved for y using numerical methods. The result is y = 3x/(x-7). This is the inverse function f^-1(x).

The domain of f is the set of all x values for which f(x) is defined. Here, f(x) is undefined only for x = 3. Hence, the domain of f is {x|x ≠ 3}. The range of f is the set of all y values that f(x) can take. Here, f(x) can take any value except 7. Hence, the range of f is {y|y ≠ 7}.

The domain of f^-1 is the set of all y values for which f^-1(y) is defined. Here, f^-1(y) is undefined only for y = 7. Hence, the domain of f^-1 is {y|y ≠ 7}. The range of f^-1 is the set of all x values that f^-1(y) can take. Here, f^-1(y) can take any value except 3. Hence, the range of f^-1 is {x|x ≠ 3}.

Answer:

2

Step-by-step explanation:

t + 1/t = 2

OK just looking at the equation, if you don't have to show work, if you guess and try t=1 you'll see 1 + 1/1 = 2 works, so t must be 1, and 1^2+1/(1^2) = 2. So the final answer is 2.

If you have to show work, t+1/t=2 is t^2+1=2t, t^2-2t+1=0, solving for t using the quadratic formula, you will get t = 1.

Then you can plug it into t^2 + 1/(t^2) to get 1^2+1/(1^2) = 1+1 = 2.

Step-by-step explanation: The solution to this system of equations will be where the two lines on the graph intersect with each other.

Notice that both of them intersect to the left of the y-axis which means our x - coordinate must be negative.

They also intersect above the x-axis so our y-coordinate must be positive.

The required sum of two orthogonal vectors is (29, 15).

The expression for y is:

y = 29 And, u is: u = 7 - 7

We need to write y as the sum of two orthogonal vectors, one in Span(u) and one orthogonal to u.

We can define two vectors as:

y = u + z, Where z is the vector orthogonal to u and lies in the plane perpendicular to Span(u).

Let's find the vector z:

Let z = (a,b) be the vector orthogonal to u.

To make it orthogonal to u, it must satisfy:

u · z = 0

(7, -7) · (a, b) = 0

a(7) + b(-7) = 0

a = b

Therefore, z = (a, a)

Now we have :

y = u + z

y = (7, -7) + (a, a) = (7 + a, -7 + a)

The sum of the vectors must be equal to y, which is equal to (29,0).

Thus,

7 + a = 29, a = 22

So, the orthogonal vector is: z = (a,a) = (22,22)

Therefore, y can be written as:

y = u + z

y = (7, -7) + (22,22)

y = (29, 15)

Hence, the required sum of two orthogonal vectors is (29, 15).

Answer:

7x-26

Step-by-step explanation:

Answer:

f(x - 4) = 7x - 26

Step-by-step explanation:

Since the original equation was f(x) = 7x + 2, then to solve the following equation, you need to use the substitution method in relation to the added number (-4). So, if f(x - 4), you would now substitute the (x - 4), in place of the previous (x). Therefore the new problem would be f(x - 4) = 7(x - 4) + 2; after distributing, you would get 7x - 28 + 2. Then further simplifying, this would be 7x - 26, after doing -28 + 2. Finally, the answer would be f(x - 4) = 7x -26.

Arlen already established that ΔRST and ΔUTS has two pairs of congruent angles and a pair of congruent included sides, which meet the ASA Congruence Criterion. Therefore:

The ASA Congruence Criterion states that for two triangles to be considered congruent to each other, both triangles must have a pair of congruent included sides and two pairs of congruent angles.

Thus, the two-column proof that shows that RS ≅ TU that Arlen is trying to write, has already established that ΔRST and ΔUTS has the following:

Two pairs of congruent angles - ∠RST ≅ ∠UTS and ∠RTS ≅ ∠UST.

A pair of congruent included sides - ST ≅ S.

Answer:

Area=14.28 Perimeter= 14.28

Step-by-step explanation:

Area of a circle = (3.14) * r^2

radius = diameter/2

radius = 4/2

r = 2

A = (3.14) * 2^2

A = (3.14) * 4

A = 12.57

since it's a half circle though, 12.57/2 = 6.29

the area of the rectangle is bh, 4*2 = 8

6.29 + 8 = 14.28

area = 14.28

perimeter of a circle, or circumference = 2(3.14)r

C = 2(3.14) * 2

C = 6.28 * 2

C = 12.57

but again, since it's a half circle, 12.57/2 = 6.29

perimeter of a rectangle = 2(l + w)

p = 2(4 + 2)

p = 2(6)

p = 12

but because the perimeter is what's on the outside, we don't count the side connecting to the circle, so it'd be 12 - 4 = 8

6.29 + 8 = 14.28

perimeter = 14.28

Answer: 4.2 x 10⁻⁴m

Step-by-step explanation: Scientific Notation is a method of writing a very large or very small number. It consists in any real number between 1 and 10 multiplied by any power of 10 (positive or negative).

The diameter of hydrogen is 5x10⁻¹¹m. There are 8.4x10⁸ atoms of hydrogen.

To determine the length of the line of atoms, you could add the diameter the number of atoms or multiply the diameter by the number of atoms:

L = 5x10⁻¹¹ * 8.4x10⁸

As it is multiplication, you can mutiply the numbers and then add the power of 10, since they are in the same base:

L = 42 x 10⁻³m

or moving comma to the left:

L = 4.2 x 10⁻⁴m

The length of the line of hydrogen atoms, in scientific notation is 4.2x10⁻⁴m

The  solution of the given system of equations is (8, -1). of the given system of equations is (8, -1).

One method to solve the given system of equations is substitution:

- Solve one of the equations for one of the variables (e.g., x = 9 + y from the second equation).

- Substitute the expression for the variable into the other equation.

- Solve the resulting equation for the remaining variable.

- Substitute the value for the remaining variable back into one of the original equations to find the value of the other variable

Using this method with the given equations

- x - y = 9 -> x = 9 + y

- 3x + 2y = 22 -> 3(9 + y) + 2y = 22

- Simplifying and solving for y: 27 + 5y = 22 -> 5y = -5 -> y = -1

- Substituting y = -1 into x = 9 + y: x = 8

To check this solution, we can substitute these values back into both original equations and confirm that they are true statements.
