We can proved that the sum of the squares of the diagonals of a parallelogram is equal to the sum of the squares of its sides.

Let's denote the vertices of the parallelogram as A, B, C, and D, with O as the midpoint of AC and BD.

First, we can see that triangles ABO and CDO are congruent by the Side-Side-Side (SSS) postulate, since they share side BD, and both have sides AB and CO of equal length due to O being the midpoint of BD. Therefore, angles AOB and COD are congruent, and we can denote their measure as θ.

Using the Law of Cosines in triangles ABO and CDO, we can express the squares of the diagonals AC and BD in terms of the sides of the parallelogram:

AC² = AB² + BC² - 2(AB)(BC)cosθ

BD² = AB² + BC² + 2(AB)(BC)cosθ

Adding these two equations together, we get:

AC² + BD² = 2(AB² + BC²)

which is the desired result. Therefore, we have shown that the sum of the squares of the diagonals of a parallelogram is equal to the sum of the squares of its sides.

Answer:

The number of houses built in Town B is 56.

Step-by-step explanation:

We are given that in 2010, the number of houses built in Town A was 25 percent greater than the number of houses built in Town B.

Also, 70 houses were built in Town A during 210.

Let the number of houses built in Town B be 'x'.

So, according to the question;

Number of houses built in Town A = Number of houses built in Town B + 25% of the houses built in Town B

\(70 = x + (25\% \times x)\)

\(70 = x(1+0.25)\)

\(x=\frac{70}{1.25}\)

x = 56

Hence, the number of houses built in Town B is 56.

If the values are exclusive, then the percentage would be slightly less than 95%.

The empirical rule can be used to calculate the percentage of variables between 39 and 63, presuming that the sample is bell-shaped and regularly distributed. According to the empirical rule, given a normal distribution, 68% of the data falls under one standard deviation from the mean, 95% in a range of two standard deviations, but 99.7% over three standard deviations.

In order to apply the scientific consensus to this issue, we must first ascertain the population's mean and standard deviation. Suppose we have this data, with the mean being 50 and the average deviation being 10.

We can determine from these values who believes in between 39 and 63 are between a pair of standard deviations of their mean (39 being a deviation of one standard deviation from the mean).

Answer:

it would be d because 2 and 4 would only make sense to be 27° and 1 to be 153

Answer:

<1 = <3 = 153

<2 = <4 = 27

Step-by-step explanation:

Angle 1 and Angle 3 are equal since they are vertical angles

<1 = <3 = 153

<1 and <2 make a straight line so they add to 180

153 + <2 = 180

<2 = 180-153

<2 = 27

<2 and <4 are equal since they are vertical angles

<2 = <4 = 27

Answer:

k = - 8

Step-by-step explanation:

given that (x - a) is a factor of f(x) , then f(a) = 0

given

(x - 1) is a factor of f(x) then f(1) = 0 , that is

3(1)³ + 5(1) + k = 0

Activity 1: Obtain the differential equation of y = At^x, where A is a constant. To find the differential equation, we need to differentiate y with respect to t. Assuming A is a constant and x is a function of t, we can use the chain rule to differentiate y = At^x.

dy/dt = d(A\(t^x\))/dt

Applying the chain rule, we have:

dy/dt = d(A\(t^x\))/dx * dx/dt

Since x is a function of t, dx/dt represents the derivative of x with respect to t. To find dx/dt, we need more information about the function x(t).

Without further information about the relationship between x and t, we cannot determine the exact differential equation. The form of the differential equation will depend on the specific relationship between x and t.

Activity 3: Prove that y = \(4e^{(Ax + B)\), where A and B are constants, is a solution of the differential equation y'' - 25y = 0. To prove that y = \(e^{(Ax + B)\) is a solution of the given differential equation, we need to substitute y into the differential equation and verify that it satisfies the equation. First, let's calculate the first and second derivatives of y with respect to x:

dy/dx =\(4Ae^{(Ax + B)\)

\(d^2y/dx^2 = 4A^2e^{(Ax + B)\)

Now, substitute y, dy/dx, and \(d^2y/dx^2\) into the differential equation:

\(d^2y/dx^2 - 25y = 4A^{2e}^{(Ax + B)} - 25(4e^{(Ax + B)})\)

Simplifying the expression, we have:

\(4A^2e^(Ax + B) - 100e^{(Ax + B)\)

Factoring out the common term \(e^{(Ax + B)\), we get:

\((4A^2 - 100)e^{(Ax + B)\)

For the equation to be satisfied, the expression inside the parentheses must be equal to zero:

\(4A^2 - 100 = 0\)

Solving this equation, we find that A = ±5.

Therefore, for A = ±5, the function \(y = 4e^{(Ax + B)\) is a solution of the differential equation y'' - 25y = 0.

First, we need to calculate the area of the city that has the radius of 5 miles. So, the population of the city is approximately 2.47 million people, and the ball of zinc weighs more than the ball of chromium.

The formula for calculating the area of a circle is as follows: A = πr², where r is the radius and π ≈ 3.14. So, the area of the city will be: A = πr² = 3.14 x 5² = 78.5 square miles.

Now, we can use the density formula to calculate the population of the city: Density = Mass/Volume

We don't have the mass, but we do have the density and the volume. Therefore, we can re-arrange the formula to calculate the mass: Mass = Density x Volume

Let's start by calculating the population density in the first circle. We know that the density is 10,000 people per square mile, and the area of the circle is: A = πr² = 3.14 x 3² = 28.26 square miles.

Therefore, the volume of this circle is: Volume = Area x Height = 28.26 x 1 = 28.26 cubic miles

Now, we can calculate the mass of people in the first circle: Mass = Density x Volume = 10,000 x 28.26 = 282,600 people.

We can repeat the same process for the remaining circles: In the second circle: Area = π(6² - 3²) = 63.62 square miles

Volume = Area x Height = 63.62 x 1 = 63.62 cubic miles, Mass = Density x Volume = 8,000 x 63.62 = 508,960 people

In the third circle: Area = π(9² - 6²) = 113.1 square miles, Volume = Area x Height = 113.1 x 1 = 113.1 cubic miles

Mass = Density x Volume = 6,000 x 113.1 = 678,600 people

In the fourth circle: Area = π(12² - 9²) = 153.94 square miles, Volume = Area x Height = 153.94 x 1 = 153.94 cubic miles, Mass = Density x Volume = 4,000 x 153.94 = 615,760 people

In the fifth circle: Area = π(15² - 12²) = 193.74 square miles, Volume = Area x Height = 193.74 x 1 = 193.74 cubic miles, Mass = Density x Volume = 2,000 x 193.74 = 387,480 people

Finally, we can add up the total mass of people from all the circles: Total Mass = 282,600 + 508,960 + 678,600 + 615,760 + 387,480 = 2,473,400 people. Therefore, the population of the city is approximately 2.47 million people.

Now, we need to calculate the masses of the balls of zinc and chromium. We can use the formula: Density = Mass/Volume, Rearranging the formula: Mass = Density x Volume

We need to find the densities of zinc and chromium. According to Wikipedia, the density of zinc is 7.14 g/cm³ and the density of chromium is 7.19 g/cm³.

Now we can calculate the masses of the balls: Volume of zinc ball: V = (4/3)πr³ = (4/3) x 3.14 x 3³ = 113.1 cm³

Density of zinc: 7.14 g/cm³, Mass of zinc: Mass = Density x Volume = 7.14 x 113.1 = 807.834 g (rounded to three decimal places). Volume of chromium ball:V = (4/3)πr³ = (4/3) x 3.14 x 2.99³ = 100.31 cm³

Density of chromium: 7.19 g/cm³, Mass of chromium: Mass = Density x Volume = 7.19 x 100.31 = 721.689 g (rounded to three decimal places). Therefore, the ball of zinc weighs more than the ball of chromium.

g(x) = 3

h(x) = 2

Let x = 10,

f(x) = 30

g(x) = 300

h(x) = 1024

Let x = 100

f(x) = 300

g(x) = 30000

h(x) = \(1.27 \times 10^{30}\)
