The surface area of the triangular prism is 120 sq cm

From the question, we have the following parameters that can be used in our computation:

Dimensions = 10 cm 5 cm 5 cm 5 cm and 4 cm

Using the formula of the surface area of the triangular prism, we have

Surface area = bh + (l1 + l2 + l3) * h

Substitute the known values in the above equation, so, we have the following representation

Surface area = 10 * 5 + (5 + 5 + 4) * 5

Evaluate

Surface area = 120

Hence, the surface area is 120 sq cm

The requried probability that a randomly selected adult has an IQ between 85 and 115 is also 0.6827.

Standardize 85 and 115 using the formula:

z = (x - μ) / σ

where x is the value we want to standardize, μ is the mean, and σ is the standard deviation.

For 85:

z = (85 - 100) / 15 = -1

For 115:

z = (115 - 100) / 15 = 1

So we want to find the probability that a standard normal random variable Z is between -1 and 1. Using a standard normal distribution table or a calculator, we can find that this probability is 0.6827.

Since IQ scores are normally distributed with a mean of 100 and a standard deviation of 15, the probability that a randomly selected adult has an IQ between 85 and 115 is also 0.6827.

The possible values of a are:

(i) A unique solution: a such that a² ≠ 5

(ii) Infinitely many solutions: a such that a² = 5

(iii) No solution: for all other values of a.

To solve this system of linear equations, use Gaussian elimination to reduce the augmented matrix to row echelon form. Then, examine the resulting matrix to determine the number of solutions.

The augmented matrix for the system is:

[1  2  -3  | 4 ]

[3  -1  5  | 2 ]

[4  1  a²-14 | a+2]

Using row operations, transform the matrix as follows:

[1  2  -3  | 4 ]

[0  -7  14 | -10]

[0  -7  a²-2 | a-6]

The third row is a linear combination of the first two rows, so we can eliminate it. This gives us:

[1  2  -3  | 4 ]

[0  -7  14 | -10]

Further simplify this matrix by dividing the second row by -7:

[1  2  -3  | 4 ]

[0  1  -2  | 10/7]

Use back-substitution to solve for the variables, start with the second row:

y - 2z = 10/7

Rearranging this equation:

y = 2z + 10/7

Substituting this into the first row:

x + 2(2z+10/7) - 3z = 4

Simplifying this equation:

x + (4/7)z = 18/7

So, the solution to the system is:

x = (18/7) - (4/7)z

y = 2z + 10/7

z is free

Now, examine the possible values of a:

(i) A unique solution: If the system has a unique solution, then there can be no free variables. From our solution above, we see that z is a free variable. Therefore, the system can have a unique solution only if a is such that the third row in the original augmented matrix does not reduce to a multiple of the first two rows. This is equivalent to the condition -7 ≠ a² - 2, or a² ≠ 5.

(ii) Infinitely many solutions: If the system has infinitely many solutions, then there must be at least one free variable. From our solution above, we see that z is a free variable. Therefore, the system can have infinitely many solutions for all values of a such that a² = 5.

(iii) No solution: If the system has no solution, then there must be a row in the reduced row echelon form that has all zeros except in the last column. However, our reduced matrix does not have this form. Therefore, the system has no solution for any value of a.

The population of the town in 2018 will be 5,040.

To predict the population in 2018, we need to use the following formula:

Population in 2018 = Population in 1993 × (1 - rate of decrease)[tex].^n[/tex]

Here, the population in 1993 is 10,500, the rate of decrease is 5.2% or 0.052 (in decimal form), and the number of years from 1993 to 2018 is 25.

Substituting these values, we get:

Population in 2018 = 10,500 × (1 - 0.052)^25

= 10,500 × 0.480

= 5,040

The slope of f(x) is less than the slope of g(x).

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If we know two points on a line, then the slope is equal to the quotient between the difference of the y-values and the difference of the x-values.

So the slope of f(x) is:

a = (3 - 0)/(0 + 2) = 3/2

And g(x) = (4/5)*x - 2

So here the slope is 4/5

To find the resultant of 4b - 2a, we need to first calculate 4b and -2a separately, and then add them together.

4b = 4(-5, 2) = (-20, 8)

-2a = -2(6, -2) = (-12, 4)

Now, we can add (-20, 8) and (-12, 4) component-wise to find the component form of the resultant:

4b - 2a = (-20, 8) + (-12, 4) = (-20 - 12, 8 + 4) = (-32, 12)

Therefore, the component form of the resultant of 4b - 2a is (-32, 12).

The type of transformation shown is vertical translation. That is option D.

Transformation of geometrical figures or points is the manipulation of a given figure to take the same shape but with different direction of its original angles.

Different types of transformations are Rotation, Reflection, Glide reflection, Translation and Dilation.

Given a polygon ABDC.

It is transformed to another polygon with the same size A'B'D'C'.

Here the polygon ABDC is just moved downwards as it is and mark is as A'B'D'C'.

In rotation or reflection transformation, the points will change it's correspondent place.

Translation is a type of transformation where the original figure is shifted from a place to another place without affecting it's size.

Since the shifting is done vertically, it is vertical translation.

Answer:

We know that point A(5, 1) maps to A'(6, -2) in the translation. To find the translation vector, we can subtract the coordinates of A from the coordinates of A':

Translation vector = A' - A = (6, -2) - (5, 1) = (1, -3)

This means that every point in the preimage moves 1 unit to the right and 3 units down to reach its corresponding point in the image.

We also know that point B'(−1, 0) is the image of a point B in the preimage. To find the coordinates of point B, we can apply the translation vector to B':

B = B' - Translation vector = (-1, 0) - (1, -3) = (-2, 3)

Therefore, the coordinates of point B in the preimage are (-2, 3).

Answer: 55/60

Step-by-step explanation:

The polynomial  (2m + 2n)6 = 12m + 12n.

For the long division, the quotient is x - 2, the remainder is 6, and the dividend can be written as (x - 2)(x² - 4x + 3) + 6.

To expand the expression (2m + 2n)6, using the distributive property of multiplication over addition:

(2m + 2n)6 = 2m(6) + 2n(6)

Simplifying further, evaluate the products:

= 12m + 12n

Therefore, (2m + 2n)6 = 12m + 12n.

Using long division to divide the polynomial x³ - 6x² + 11x - 6 by the polynomial x² - 4x + 3. The steps are as follows:

      x - 2

------------------

x² - 4x + 3 | x³ - 6x² + 11x - 6

- (x³ - 4x² + 3x)

      - 2x² + 8x

      - 2x² + 8x - 6

                + 6

Therefore, x³ - 6x² + 11x - 6 = (x - 2)(x² - 4x + 3) + 6.

So the quotient is x - 2, the remainder is 6, and the dividend can be written as (x - 2)(x² - 4x + 3) + 6.
