Both the largest and the tiniest walls of a skew are determined by an intersection of the lines that connect that make up its ends. A junction could possibly bring two routes together. Another result of two objects interacting is an angle. They most closely resemble dihedral shapes. Two line beams can be arranged in a variety of ways between their extremities to form a two-dimensional curve.

Here,

c = 96 °(A pair of vertically opposite angles are always equal to each other)

a + c = 180°(a vertical angle and its adjacent angle are supplementary angles, i.e., they add up to 180 degrees)

so, a= 180°-96°

a= 84°

therefore, b = 84°(A pair of vertically opposite angles are always equal to each other)

as shown in figure, 2e = 84°

that is, e = 84°/2

e = 42°

2e+f = 180°(a vertical angle and its adjacent angle are supplementary angles, i.e., they add up to 180 degrees)

f=180°-2e (placing the value of e)

Answer:

To find the monthly lease payment, we need to use the formula:

Monthly lease payment = (Net capitalized cost - Residual value) / Lease term in months

where:

Net capitalized cost = negotiated price - down payment

Residual value = percentage of MSRP x MSRP

Lease term in months = 36

First, we need to calculate the net capitalized cost:

Net capitalized cost = $49,000 - $4,000 = $45,000

Next, we need to calculate the residual value:

Residual value = 49% x $51,500 = $25,235

Now we can plug in the values and solve for the monthly lease payment:

Monthly lease payment = ($45,000 - $25,235) / 36 = $548.76

Therefore, the monthly lease payment is approximately $548.76.

The third side of the right angled triangle is 45.

What is right angled triangle?

A right angled triangle, also known as a right triangle, is a type of triangle that has one angle that measures exactly 90 degrees, called the right angle. This angle is formed where the two shorter sides of the triangle meet.

To solve this problem, we can use the concept of special right triangles, specifically the 3-4-5 right triangle. In a 3-4-5 right triangle, the sides are in the ratio of 3:4:5.

Let's label the length of the triangle as [tex]$L$[/tex], the height as [tex]$H$[/tex], and the hypotenuse as [tex]X[/tex].

The Pythagorean theorem states that in a right triangle, the sum of the squares of the legs is equal to the square of the hypotenuse. Therefore, we can set up the following equation:

[tex]$$ L^2 + H^2 = X^2 $$[/tex]

Substitute the given values.

We are given that [tex]$L = 27$[/tex] and [tex]$H = 36$[/tex], so we can substitute these values into the equation:

[tex]$$ 27^2 + 36^2 = X^2 $$[/tex]

Simplify the equation.

Evaluating the squares on the left side, we get:

[tex]$$ 729 + 1296 = X^2 $$[/tex]

Simplifying the right side, we get:

[tex]$$ 2025 = X^2 $$[/tex]

Solve for X.

Taking the square root of both sides, we get:

[tex]$$ X = \sqrt{2025} $$[/tex]

[tex]$$ X = 45 $$[/tex]

In the exponential decay, A) r = -0.0839 , B) r = -8.39% , C) Value=$11,800.

What is exponential decay?

The term "exponential decay" in mathematics refers to the process of a constant percentage rate reduction in an amount over time. It can be written as y=a(1-b)x, where x is the amount of time that has passed, an is the initial amount, b is the decay factor, and y is the final amount.

To find the annual rate of change between 1992 and 2006, we can use the formula:

r = [tex](V_2/V_1)^{1/n}-1[/tex]

where V1 is the initial value, V2 is the final value, and n is the number of years between the two values.

=>r = -0.0839

Therefore, the rate of change between 1992 and 2006 is -0.0839.

To express the rate of change in percentage form, we can multiply the result from part A by 100:

=>r = -0.0839 x 100

=> r = -8.39%

Therefore, the rate of change between 1992 and 2006 is a decrease of 8.39%.

To find the value of the car in the year 2009, we can assume that the value continues to drop at the same percentage rate as calculated in part A.

From 2006 to 2009, there are 3 years. So, using the formula for exponential decay, we have:

where V0 is the value in 2006, r is the rate of decrease, and n is the number of years between 2006 and 2009.

=>V = 11792.51

Therefore, the value of the car in the year 2009 would be approximately $11,800 (rounded to the nearest $50).

There is significant evidence that the proportion of frogs with elevated mercury content is different than 0.5, The p-value is approximately 0.038.

What is significant evidence?

To test whether the proportion of frogs with elevated mercury content is significantly different from 0.5, we can use a one-sample proportion test. The null hypothesis is that the true proportion is 0.5, and the alternative hypothesis is that it is different from 0.5.

Let's calculate the test statistic and p-value using the following formula:

z = (p - P0) / √(P0*(1-P0)/n)

where p is the sample proportion (17/50 = 0.34), P0 is the null hypothesis value (0.5), and n is the sample size (50).

z = (0.34 - 0.5) / √(0.5*0.5/50) = -2.07

The calculated z-value is -2.07. We can find the p-value by looking up the area to the left of -2.07 in the standard normal distribution table or by using a statistical software package. The p-value is approximately 0.038.

Since the p-value (0.038) is less than the alpha level of 0.15, we can reject the null hypothesis and conclude that there is significant evidence that the proportion of frogs with elevated mercury content is different than 0.5.

A graph of the coordinates of the vertices of the image after a dilation by the given scale factor and center of dilation is shown in the image below.

In Geometry, dilation simply refers to a type of transformation which typically changes the size of a geometric object, but not its shape.

Next, we would apply a dilation to the coordinates of the pre-image by using a scale factor of 0.5 centered at the origin as follows:

Ordered pair J (-8, 0) → J' (-8 × 0.5, 0 × 0.5) = J' (-4, 0).

Ordered pair K (-4, 4) → K' (-4 × 0.5, 4 × 0.5) = K' (-2, 2).

Ordered pair L (-2, 0) → L' (-2 × 0.5, 0 × 0.5) = L' (-1, 0).

Next, we would have to dilate the coordinates of the preimage by using a scale factor of 1/3 centered at the point B (3, 3) by using this mathematical expression:

(x, y)  →  (k(x - a) + a, k(y - b) + b)

For coordinate A, B, and C, we have;

Coordinate A = (9, 9)  →  (1/3(9 - 3) + 3, 1/3(9 - 3) + 3) = (5, 5).

Coordinate B = (3, 3)  →  (1/3(3 - 3) + 3, 1/3(3 - 3) + 3) = (3, 3).

Coordinate C = (6, 0)  →  (1/3(6 - 3) + 3, 1/3(0 - 3) + 3) = (4, 2).

For coordinate D, E, and F, we have;

Coordinate D = (2, -2)  →  (1.5(2 - 4) + 3, 1.5(-2 + 2) + 3) = (0, 3).

Coordinate E = (4, -2)  →  (1.5(4 - 4) + 3, 1.5(-2 + 2) + 3) = (3, 3).

Answer: y = (1/12)x^2 - 2

Step-by-step explanation:

The equation of a parabola in vertex form is given by:

y = a(x-h)^2 + k

where (h,k) is the vertex of the parabola and "a" is a coefficient that determines the shape of the parabola.

In this case, the vertex is given as (0, -2), so h = 0 and k = -2. Also, the parabola passes through the point (6, 1), which means that when x = 6, y = 1. We can use this information to solve for "a".

Substituting the values of h, k, x, and y in the equation, we get:

1 = a(6-0)^2 - 2

Simplifying this equation, we get:

1 + 2 = 36a

3 = 36a

a = 3/36

a = 1/12

Now that we know the value of "a", we can substitute it in the vertex form equation to get the final equation of the parabola:

y = (1/12)(x-0)^2 - 2

Simplifying this equation, we get:

y = (1/12)x^2 - 2

Therefore, the equation of the parabola in vertex form is y = (1/12)x^2 - 2.

Answer: A. To find the equation that models this relation, we can plot the data and look for a trend.

From the graph, we can see that the data follows an exponential growth pattern. The equation for exponential growth is:

y = ab^x

where y is the final population, a is the initial population, b is the growth rate, and x is the time in hours.

Using the data from the table, we can find the value of b:

b = y/x

where y is the population after x hours.

For example, after 2 hours, the population is 5000:

b = 5000/2 = 2500

We can repeat this process for each time period and find the average value of b:

b = (2500 + 3125 + 3906.25 + 4882.81 + 6103.51 + 7629.38) / 6 = 4275.5

Now that we have the value of b, we can find the equation that models the relation:

y = 2000(4275.5)^x

Rounding to one decimal place:

y = 2000(4.3)^x

B. Using the equation, we can find the population after 12 and 24 hours:

y = 2000(4.3)^12 ≈ 8,898,335.7

y = 2000(4.3)^24 ≈ 7.42 x 10^13

(all side lengths were doubled; multiplied by 2) which is an enlargement any scale factor greater then 1 is an enlargement which means the triangle size is being increased. Any scale factor less than one is a shrinkage. The 2 triangles have the same angle but not the same side lengths.

What is a dilation:

A dilation is a geometric transformation that changes the size of a shape. The only thing the changes in a dilation is the size. It can either get bigger or smaller (angle measurements DO NOT change)

Conclusion:

triangle similarity can be proved by AA similarity postulate.

i hope this helps :)

happy geometry studying!!
