The area of the triangle with the given vertices is 6.6.

The formula for finding the area of a triangle given its vertices is A = 1/2 abs(x1y2 + x2y3 + x3y1 - x2y1 - x3y2 - x1y3). To calculate the area of the given triangle, we substitute the coordinates of each vertex into the formula. First we find the three cross-products: x1y2 = 0 * 6 = 0, x2y3 = 2.8 * 6 = 16.8, and x3y1 = 5 * 0 = 0. Then, we find the two products of the y-coordinates: x2y1 = 2.8 * 0 = 0, and x3y2 = 5 * 6 = 30. Lastly, we find the product of the x-coordinates: x1y3 = 0 * 6 = 0. Adding all these up, we get 0 + 16.8 + 0 - 0 - 30 - 0 = -13.2. We then take the absolute value of the result, abs(-13.2) = 13.2. Finally, we multiply the result by 1/2 to get the area of the triangle, A = 1/2 abs(-13.2) = 1/2 * 13.2 = 6.6. Therefore, the area of the triangle with the given vertices is 6.6.

Round this number to the nearest thousand, giving the final answer of 839,000.

Population is the number of people living in a given area at a particular time. It can refer to a geographic region, such as a city, state, country, or the world. It is usually measured as the total number of people within a certain area and can be determined through a variety of methods, such as the census or survey. Population growth and decline are important indicators of a country's economic and social development, as well as its demographics.

a. y = 696,000 * 1.04^t

b. The population after 20 years will be approximately 839,000. This can be calculated by plugging in t = 20 into the exponential function: y = 696,000 * 1.04^20 = 838,903.8. Round this number to the nearest thousand, giving the final answer of 839,000.

The resulting point's coordinates, G', are rotated 90° clockwise around in the origin are (-1 , -1 ).

A coordinate plane is a two-dimensional plane created by the intersection of the y-axis, a vertical line, and the x-axis, a horizontal line. These really are perpendicular lines that cross at zero, which is known as the origin.

Quadrant one (QI) is the upper right fourth of a coordinate plane, where all coordinates are positive. Quadrant two (QII) is the coordinate plane's upper left fourth. Quadrant three (QIII) is the fourth from the bottom left. Quadrant four (QIV) is the fourth from the bottom right.

Point G(1,1)

X= 1 ,Y = 1

We can see that the point lies in the first quadrant because the value of X and Y are the positive.

the coordinates of the resulting point, G'  is rotated 90° clockwise around the origin.

As we know that the quadrant plane is divided into 4 part but if the point G rotates at 90 clockwise the the point will shift to the 4 quadrant and in the 4 quadrant the value of X and Y change And it became negative.

Step-by-step explanation:

The expected size of the largest gap between adjacent cars (as a function of l) is l/(n + 1), and the expected size of the smallest gap between adjacent cars is 2.

Let us consider that cars of length 2 try to park on a length l road. Each minute, a new car parks at a uniformly random spot on the road without crashing into another car or running off the road.

When no more cars fit, the expected size of the largest gap between adjacent cars is l/(n + 1) and the smallest gap is 2.

The expected size of the largest gap between adjacent cars (as a function of l) is l/(n + 1).

Let n be the number of cars parked on the road. Then the total length of the cars parked is 2n.

If the largest gap is a distance g, then the total length of the gaps is l − 2n. Then,gap length:

g (n + 1) ≤ l - 2ng ≤ l − (n + 1)g

The coterminal  angles for the 290 degrees are 650 degree, -70 degree and reference angle is 70 degree respectively.

Two different angles that have the identical starting and ending edges termed coterminal angles however, since one angle measured clockwise and the other determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.

We have an angle:

290 degree

To find the coterminal angle, add and subtract 360 degree in the angle 290 degree.

Coterminal angle = 290 + 360 = 650 degree

                               = 290 - 360 = -70 degree

Reference angle = 360 - 290 = 70 degree

Thus, the coterminal  angles for the 290 degrees are 650 degree, -70 degree and reference angle is 70 degree respectively.

Answer: look at the image for the answer and solution

Step-by-step explanation:

The natural values of n for which the difference (2-2n) - (5n-27) is positive are 1, 2, 3, and 4.

To find the natural values of n for which the difference (2-2n) - (5n-27) is positive, we need to simplify the expression and then solve for n.

(2-2n) - (5n-27) = 2 - 2n - 5n + 27

= -7n + 29

So, we need to find the natural numbers n for which -7n + 29 > 0.

To do this, we can solve for n as follows

-7n + 29 > 0

-7n > -29

n < 29/7

Since n is a natural number, it must be an integer greater than or equal to 1. Therefore, the natural values of n for which the difference (2-2n) - (5n-27) is positive are 1, 2, 3, and 4.

The solution to the differential equation y''(t) = 1 - t^17 with initial condition y(1) = 12 is:

y(t) = (1/2)t^2 - (1/342)t^19 + (217/18)t + (19805/342)

None of the provided options (a, b, c, d) match the correct solution.

To solve the given differential equation y''(t) = 1 - t^17 with the initial condition y(1) = 12, we can integrate the equation twice.

Integrating the equation once will give us y'(t):

y'(t) = ∫(1 - t^17) dt

y'(t) = t - (1/18)t^18 + C₁

Now, we need to apply the initial condition y(1) = 12 to determine the value of the constant C₁:

12 = 1 - (1/18) + C₁

C₁ = 12 + (1/18) - 1

C₁ = 217/18

Next, we integrate y'(t) to find y(t):

y(t) = ∫(t - (1/18)t^18 + 217/18) dt

y(t) = (1/2)t^2 - (1/342)t^19 + (217/18)t + C₂

Finally, we apply the initial condition y(1) = 12 to determine the value of the constant C₂:

12 = (1/2) - (1/342) + (217/18) + C₂

C₂ = 12 - (1/2) + (1/342) - (217/18)

C₂ = (20619 - 1 + 6 - 819)/(342)

C₂ = 19805/342

Therefore, the solution to the differential equation y''(t) = 1 - t^17 with initial condition y(1) = 12 is:

y(t) = (1/2)t^2 - (1/342)t^19 + (217/18)t + (19805/342)

Therefore, the correct choice is A, and the expression can be written as: 2 sin 15° cos 15° = sin(30°) = 1/2

The given expression is 2 sin 15° cos 15°. This expression can be written using the double angle formula for sine, which is sin(2θ) = 2 sinθ cosθ. In this case, θ is 15°.
So, 2 sin 15° cos 15° can be rewritten as sin(2 * 15°), which simplifies to sin(30°).
Now, we can find the exact value of sin(30°) using the properties of a 30-60-90 right triangle. In such a triangle, the side ratios are 1:√3:2, where the side opposite the 30° angle has a length of 1, the side opposite the 60° angle has a length of √3, and the hypotenuse has a length of 2. The sine function is defined as the ratio of the length of the opposite side to the length of the hypotenuse. So, sin(30°) = 1/2.

There are 8 players who weigh between 169 and 194 pounds.

To answer this question, we can look at the box plot to understand the distribution of weights on the football team. The box plot shows us the minimum, maximum, median, and quartiles of the team's weights. The left quartile is 169 pounds, and the right quartile is 194 pounds. This means that 25% of the team's players weigh between 169 and 194 pounds. Since the team has 36 players, 25% of 36 is 9. However, since we are looking at the number of players between 169 and 194 pounds, we need to subtract 1 since the right quartile of 194 pounds is included in the number of players. Thus, there are 8 players who weigh between 169 and 194 pounds.
