The Vertices Of YEAR Are Y(1,-4) E(3,0), A (-1,2) And R( -3,-2) . Prove That YEAR Is A Square

Answers

Answer 1

To prove that YEAR is a square, we need to show that all four sides have the same length and all four angles are right angles (90 degrees).

Side Lengths: To find the lengths of the sides, we can use the distance formula:

d = √((x2 - x1)² + (y2 - y1)²)

For example, to find the length of the side that connects Y and E, we can use the following calculation:

d = √((3 - 1)² + (0 - (-4))²) = √((2)² + (4)²) = √(4 + 16) = √20

We can use the same formula to calculate the lengths of the other sides. By doing so, we will find that the length of all four sides are the same, which is √20. This means that all four sides of YEAR are congruent, and therefore it is a square.

The mean height of the members of the football club is 163.4 to rounded to 1 decimal place.

How to calculate the mean height

The mean height It is calculated by summing up all the data values and dividing by the total number of data points. The mean can also be represented by the point at which the frequency polygon would balance if it were a physical object.

The values with their corresponding frequencies are:

height: 120 × frequency: 8 = 960

height: 140 frequency: 11 = 1549

height: 160 frequency: 17 = 2720

height: 180 frequency: 18 = 3240

height: 200 frequency: 10 = 2000

sum frequency = 64

sum of all data values = 10460

mean height = 10460/64

mean height = 163.4375

Therefore, the mean height of the members of the football club is 163.4 to rounded to 1 decimal place.

Which is a correct solution for the system of inequalities?

When we have a system of inequalties (so we have 2 or more inequalities) the solutions are the points (x, y) that are solutions of both inequalities at the same time.

Here we can see the graph of a system, such that the solution set of one of the inequalities is represented by the red shaded area, and the solution set of the other inequality is represented by the blue shaded area.

The solution set of the system is represented by the intersection between the areas, which is the purple area.

Rick paddles a kayak 20 miles upstream in 4 hours. The return trip downstream takes him 2. 5 hours. What is the rate that Rick paddles in still water? What is the rate of the current?

Answers

For the given time taken to cover 20 miles from upstream and downstream the rate of Rick paddles in still water is 6.5mph and rate of current is 1.5mph.

Let us consider 'x' be the rate at which Rick paddles in still water

'y' be the rate of the current

Distance covered while going in upstream = 20 miles

Time taken while going 20 miles upstream = 4 hours

Rate of upstream = 20 / 4

⇒ x - y = 5 miles /hours    ___(1)

Distance covered while going in downstream = 20 miles

Time taken while going 20 miles downstream = 2.5hours

Rate of downstream = 20 / 2.5

⇒ x + y = 8 miles /hours    ___(2)

Solve (1) and (2) we get,

x - y = 5

x + y = 8

2x = 13

⇒ x = 6.5miles per hour

y = x - 5

⇒ y = 1.5 miles per hour

Therefore, the rate of the Rick paddles in the still water is 6.5mph and the rate of the current is 1.5mph.

The values of n for the given expression such that -15< 3n < 6 is -5 < n < 2.

What are inequalities?

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

The given expression is:

-15< 3n < 6

Divide all the sides of the equation with 3 to isolate the value of n.

Throughout the solar system, solar energy is continuously emitted by the sun. The Earth is warmed by solar energy, which also affects the weather, the wind, and the survival of plant and animal life. Electromagnetic radiation, which is a kind of energy, heat, and light, is released from the sun (EMR).

What is solar system?Anything produced by the sun is considered to be solar energy.Nuclear fusion that occurs in the sun is the source of solar energy. Hydrogen atom protons clash ferociously in the sun's core, where they fuse to form helium atoms, which is the process of fusion.An large quantity of energy is released during this process, which is sometimes referred to as a PP (proton-proton) chain reaction. Around 620 million metric tons of hydrogen are fused by the sun every second in its core. Other stars, similar in size to our sun, also experience the PP chain reaction, which supplies them with ongoing heat and energy. These stars have an average Kelvin temperature of 4 million degrees (about 4 million degrees Celsius, 7 million degrees Fahrenheit).The CNO cycle is responsible for energy production in stars that are around 1.3 times larger than the sun. Carbon, nitrogen, and oxygen (C, N, and O) are required for the CNO cycle to convert hydrogen to helium. As of right now, the CNO cycle produces less than 2% of solar energy.

The square root of 224 in long division is 14.96

The term square root in math is defined as  a factor of a number that, when multiplied by itself, gives the original number

Here we know that we need to find the square root of √224.

In order to solve this one we have to do the following steps,

Here we have to start dividing the digits from the right side into pairs of two by drawing a line on top of them. In the case of 224, then we have two pairs 24 and 2.

And then we have to find a number(z) whose square is ≤ 2.

Then the value of z will be 1 as 1 × 1 = 1 ≤ 2.

Here we get the value of quotient and the remainder as 1 and now we have to add the divisor z with itself and get the new divisor 2z (2).

And then we have to drag down the next pair and find a number (n) such that 2n × n ≤ 124 here we have the value of n comes out to be 4.

Finally we have to add a decimal in the dividend (224) and quotient (14) simultaneously.

Here we have to add 2 pairs of zero in the dividend after the decimal  and repeat the above step for the remaining three pairs of zero.

The ordered pair could represent the image of point C(5, 2) after the dilation is (2.5, 1)

Which ordered pair could represent the image after the dilation?

If we have a general point (x, y) and we apply a dilation with the origin as the center of a scale factor k, then the coordinates of the image after the dilation is (k*x, k*y)

Here we want to see which point can be the image of (5, 2) after the dilation, it will must have the form (k*5, k*2)

The only point that has this form is the one on the third option, where we can write:

(2.5, 1) = (k*5, k*2)

Then we have two equations:

2.5 = k*5

1 = k*2

a spherical snowball is rolled in fresh snow causing it grow so fast that its radius increases at a rate of 2 in/sec. how fast is the volume of the snowball increasing when the radius is 9 in

Answers

The volume is increasing at a rate of 784 * pi cubic inches per second.

The volume of a sphere is given by the formula V = (4/3) * pi * r^3, where r is the radius of the sphere.

We can find the rate of change of the volume with respect to time by taking the derivative of V with respect to time.

dV/dt = (4/3) * pi * 3r^2 * dr/dt

Given that the radius is increasing at a rate of 2 in/sec, we can substitute this value into the equation and find the rate at which the volume is increasing:

dV/dt = (4/3) * pi * 3 * 9^2 * 2 in^3/sec = 784 * pi in^3/sec

So, when the radius of the snowball is 9 inches, the volume is increasing at a rate of 784 * pi cubic inches per second.
