The mass of the lamina is 5k/3 and its center of mass is (0, 5/8).

To find the mass of the lamina, integrate the density function over the region d:

M = ∫∫d 5ky dA

= 5k ∫0^1 ∫0^(1-x^2) y dy dx

= 5k/3

To find the center of mass, we need to find the moments Mx and My and divide by the total mass M:

Mx = ∫∫d x * 5ky dA

= 5k ∫0^1 ∫0^(1-x^2) xy dy dx

= 0

My = ∫∫d y * 5ky dA

= 5k ∫0^1 ∫0^(1-x^2) y^2 dy dx

= 5k/8

Therefore, the center of mass is (Mx/M, My/M) = (0, 5/8).

Triangle AEF, triangle BFD, and triangle CDE are each similar to triangle ABC in an orthic triangle.

In an orthic triangle, triangle AEF, triangle BFD, and triangle CDE are formed by drawing altitudes from the vertices of triangle ABC to the opposite sides. These altitudes intersect at points E, F, and D, respectively. By construction, each of these triangles shares one angle with triangle ABC.

Since the altitudes of triangle ABC are perpendicular to the respective sides, the angles formed between the altitudes and the sides are right angles. Therefore, triangle AEF, triangle BFD, and triangle CDE each have a right angle, which is the same as the right angle in triangle ABC.

Additionally, since the altitudes are drawn from the vertices of triangle ABC, the corresponding angles of triangle AEF, triangle BFD, and triangle CDE are congruent to the corresponding angles of triangle ABC. These corresponding angles are shared between the triangles, establishing similarity.

The expression representing the length of one side of the square is √(2 − 10x + 25) meters.

The area of a square is given by the formula A = \(s^2\), where A represents the area and s represents the length of one side of the square. In this case, the given expression represents the area of the square, which is (2 − 10x + 25) square meters. To find the length of one side, we need to take the square root of the area expression.

By taking the square root of (2 − 10x + 25), we can simplify it as follows:

√(2 − 10x + 25) = √(27 − 10x)

Now, it's important to note that the length of one side of a square cannot be negative since it represents a physical measurement. Therefore, we only consider the positive square root.

Hence, the expression representing the length of one side of the square is √(2 − 10x + 25) meters. This represents the positive value of the square root, which gives us the length of one side of the square.

the limit is less than 1, we can conclude that the series converges, according to the Root Test.

Using the root test, we take the limit as n approaches infinity of the nth root of the absolute value of an, which is (n/2)^1/n. Simplifying, we get (1/2)^(1/n). Since the limit is less than 1, the series converges by the root test. Using the Root Test to determine if the series converges, we analyze the limit of the nth root of the absolute value of the given term a_n:
a_n = n/2^n
First, let's find the nth root of the absolute value of a_n:
|a_n|^1/n = |(n/2^n)|^1/n
As n goes to infinity, we can analyze the limit:
lim (n→∞) (|n/2^n|)^1/n
Since 2^n grows exponentially faster than n, the fraction n/2^n approaches 0 as n approaches infinity. Therefore, the limit is:
lim (n→∞) (0)^1/n = 0
Since the limit is less than 1, we can conclude that the series converges, according to the Root Test.

The focal length of the lens is mathematically given as

f = 17.15cm

Generally, the equation for focal length is mathematically given as

1/f = (n-1)(1/R1 -1/R2)

f: focal length of the lens

n: refractive index of the lens

R1 radius of the front surface

R2 radius of the back surface

R1(front surface) = 20cm

R2(back surface) = 30cm

n = 1.70

therefore,

1/f = (1.70-1)(1/20 -1/-30)

1/f = 0.70 * 0.083

1/f = 0.0581

f = 17.15cm

Answer:

∠ ABD = 49°, ∠ CBD = 28°

Step-by-step explanation:

∠ ABD + ∠ CBD = ∠ ABC , substitute values

3x + 22 + 5x - 17 = 77 , that is

8x + 5 = 77 ( subtract 5 from both sides )

8x = 72 ( divide both sides by 8 )

x = 9

Thus

∠ ABD = 3x + 22 = 3(9) + 22 = 27 + 22 = 49°

∠ CBD = 5x - 17 = 5(9) - 17 = 45 - 17 = 28°

The ethnicity of respondents in a political poll of randomly selected adults is an example of a categorical variable.

A categorical variable is a type of variable that represents data that can be categorized into distinct groups or categories. In this case, the ethnicity of the individual respondents in the political poll represents different categories such as Asian, African American, Hispanic, Caucasian, etc. Each respondent falls into one of these categories based on their ethnicity.

The variable is categorical because it does not have numerical values that can be quantified or measured. Instead, it represents qualitative data that can be described using labels or categories.

Therefore, the ethnicity of the individual respondents in a political poll of randomly selected adults is an example of a categorical variable.
