Special right triangles are triangles with specific angle measurements whose side lengths have patterns.

45-45-90 Triangle

The triangle above is a 45-45-90 triangle since it has two 45-degree angles. For this explanation, let a and b represent the legs of a right triangle and c be the hypotenuse. In this type of triangle, the legs are equal, so a=b. The hypotenuse is [tex]\sqrt{2}[/tex] times the leg length. So, c = a√2.

Finding x and y

In this problem, x is one of the legs. This means that x = 2 since 2 is the length of the leg. The y-value represents the hypotenuse, so we can multiply the leg by √2. Thus, y = 2√2.

The length of LN for the triangle is 18.

A triangle is a three-sided polygon because it has three edges and three vertices. The most important attribute of a triangle is the sum of its internal angles to 180 degrees

Given triangle JKL,

and MN is parallel to JK,

taking ΔJKL and ΔLMN

∠L = ∠L  (common angle)

because MN is parallel to JK, so corresponding angles are equal,

so ∠K = ∠N

and ∠J = ∠M

ΔJKL ≈ ΔLMN(triangles are similar)

since both triangles are similar the ratio of their corresponding sides is equal,

JL/LM = JK/MN = LK/LN

and JK = 55 and LK = 33

and MN = 12 + LN

JK/MN = LK/LN

substitute the values

55/(12 + LN) = 33/LN

55LN = 33(12 + LN)

Answer:

3.2 miles

Step-by-step explanation:

To approximate the height of the mountain, we need to use the tangent function in trigonometry. We have two angles of elevation and the distance between the observer and the mountain, which we can use to create a right triangle.

Let h be the height of the mountain and d be the distance from the observer to the foot of the mountain.

At the first observation, we have:

tan(3.5°) = h/d

And at the second observation, when the observer is 11 miles closer to the mountain:

tan(9°) = h/(d-11)

Dividing the two equations, we have:

tan(9°) / tan(3.5°) = h/(d-11) / h/d

Solving for h, we have:

h = (d * tan(9°)) / (tan(3.5°) + 1)

We don't have an exact value for d, so we can use an estimate based on the difference in distance between the two observations.

Since d-11 = 11 miles, we have:

d = 11 * 2 = 22 miles

Using this estimate and the given angles, we can approximate the height of the mountain:

h = (22 * tan(9°)) / (tan(3.5°) + 1) = (22 * 0.156434465) / (0.066012183 + 1)

= 22 * 0.156434465 / 1.066012183 = 22 * 0.146838446 = 3.23 miles

The height of the mountain is approximately 3.2 miles to one decimal place.

The coordinates of point A'  and B' are A'(-12,8) and B'(20, 0)

A dilation is a transformation that changes the size of a figure but not its shape.

In a dilation with respect to the origin, a point (x, y) is transformed to a point (kx, ky) where k is a scale factor.

In this case, the point A (-3, 2) and B (5, 0) are transformed under a dilation of 4 with respect to the origin.

So the images are

A' = (kx, ky) = (-3*4, 2*4) = (-12, 8)

B' = (kx, ky) = (5*4, 0*4) = (20, 0)

Answer:

Equation is

[tex]\mbox {\large \boxed{g(m) = 4.411 (0.94988)^m}}[/tex]

Step-by-step explanation:

We have to translate the information in the table as an equation of the form

[tex]g(m) = P(1 + r)^m\cdots \cdots(1)[/tex]

Let's take the date from the table

For m = 1, g(m) = 4.19

Substituting these values in equation (1) we get:
[tex]g(1) = P(1 + r)^1[/tex]

[tex]4.19 = P(1 + r)^1[/tex]

[tex]P(1 + r)^1 = 4.19 \; \textrm{ (by switching sides)}[/tex]

[tex]P(1+r) = 4.19\; \cdots \cdots (2)\\\textrm{ (an expression raised to the power 1 is the expression itself)}[/tex]

For the next entry in the table, m = 2, g(m) = 3.98

Plugging into (1)

[tex]3.98 = P(1 + r)^2 \cdots\cdots(3)[/tex]
or

[tex]P(1 + r)^2 = 3.98[/tex]

Divide equation (3) by equation (2)

[tex]\dfrac{P(1+r)^2}{P(1+r} = \dfrac{3.98}{4.19}[/tex]

[tex]\textrm{The P terms cancel and } \dfrac{(1 + r)^2}{(1+r)} = 1 + r[/tex]

==> [tex]1 + r = \dfrac{3.98}{4.19}\\\\1 + r = 0.94988\\\\[/tex]

Plugging this value of 1 + r into equation (2):

[tex]P( 0.94988) = 4.19\\\\P = \dfrac{4.19}{0.94988}\\\\P = 4.411\\\\[/tex]

So the equation is

[tex]g(m) = 4.411 (0.94988)^m[/tex]

We can verify this is correct for m = 2, 3 and 4

[tex]m\quad\quad g(m) = 4.411(0.94988)^m\\\------------------\\2\quad\quad 4.411(0.94988)^2 = 3.97992 \approx 3.98\\\\3\quad\quad 4.411(0.94988)^3 = 3.78044 \approx 3.78\\\\3\quad\quad 4.411(0.94988)^4 = 3.59097 \approx 3.59\\\\[/tex]

Step-by-step explanation:

The area of the lawn that will be watered by the sprinkler is 191.1 square feet, rounded to the nearest tenth.

Area is a measurement of the size of a two-dimensional surface, such as a square, rectangle, or circle. It is calculated by multiplying the length of the surface by its width. Area can also be measured in terms of square units, such as square feet or square meters. Area is an important concept in mathematics and is used to measure the size of shapes and objects. It is also used to find the total area of a group of shapes.

To calculate the area, use the formula A = r2θ, where A is the area, r is the radius, and θ is the central angle in radians. In this scenario, the radius is 10 ft and the central angle is 30°, or π/6 radians. Plugging these numbers into the formula, we get A = (10 ft)2(π/6 radians), or 191.1 square feet.

Answer:

Y=4cm

Step-by-step explanation:

We can use the relationship between the side length and area of a square to solve for Y. Let's call the area of the small square "A" and the area of the large square "B". From the problem statement, we know:

A = 1/9 * B

Since the area of a square is equal to the side length squared, we can substitute this relationship into the equation above:

Y^2 = 1/9 * 12^2

Solving for Y:

Y^2 = 1/9 * 144

Y^2 = 16

Y = sqrt(16)

Y = 4

So, the side length of the small square is 4 cm.

Answer:

162/5 hours.

Step-by-step explanation:

Let's call the normal depth of the river "D". Since 2/3 of the way to go back to normal is still flooded, the current depth of the water is D + 2/3D = 5/3D.

The flood waters recede at a rate of 1/9 the flood level per hour, so the change in water level each hour is -1/9 * 5/3D = -5/27D.

To find the number of hours it takes to go from the current depth (5/3D) to the normal depth (D), we need to divide the change in depth (-5/27D) by the change in depth per hour (-5/27D): (5/3D - D) / (-5/27D) = (5/3D - D) / (-5/27D) = -(5/3D - D) / (5/27D) = (2/3D) / (5/27D).

This can be simplified to 2/3 * 27/5 = 162/5 hours. The answer is 162/5 hours.

Answer: Since the flood waters still have 2/3 of the way to go back down to reach the normal level, it means that 1/3 of the flood level has already receded.

If the flood level recedes at a rate of 1/9 the flood level per hour, then it will take 1/9 * 1 hour = 1 hour to recede 1/9 of the flood level.

Therefore, to recede 2/3 of the flood level, it will take 2/3 * 1/9 hours = 2/27 hours.

Since there are 60 minutes in 1 hour, the time it takes for the flood waters to reach the normal level in minutes is: 2/27 hours * 60 minutes/hour = 20 minutes.

Therefore, it will take 20 more minutes for the water to reach its normal depth.

In mathematics, The function is called as continuous at the particular value of x,  if right hand limit, left hand limit and the value of function at x all are equal.

RHL   = LHL  = F(x)

Limit exist and continuous

Given that,

F(x)  =   (x√x)/(x - 6)²

To check whether it is continuous at x = 36

First taking LHL,

[tex]\lim_{h \to \00}[/tex]    [(36-h)√(36-h)]/((36-h) - 6)²

[tex]\lim_{h \to \00}[/tex]  [(36-0)√(36-0)]/((36-0) - 6)²

⇒   (36 x 6)/30²

⇒    6/25

Now, taking RHL

[tex]\lim_{h \to \00}[/tex]    [(36+h)√(36+h)]/((36+h) - 6)²

[tex]\lim_{h \to \00}[/tex]  [(36+0)√(36+0)]/((36+0) - 6)²

⇒   (36 x 6)/30²

⇒    6/25
