The school building's actual length is 40 m.

Length exists as a measure of distance. In the International System of Quantities, length exists as a quantity with dimension distance. In most systems of measure a base unit for length is selected, from which all other units exist derived. In the International System of Units system, the base unit for length exists as the meter.

Given: School building length is given 40 cm on the map

scale used is 1 cm = 1 m

The scale utilized exists 1 cm = 1 m

1 cm in map = 1 m in actual

⇒ 40 cm in map = 40 m in actual

School building length in map = 40 cm

⇒ Actual Length of the school building is 40 m

Therefore, the school building's actual length is 40 m.

Using the concepts of mean and standard deviation, and the central limit theorem, it is found that:

a. The mean is of: 3.3

b. The standard deviation is of: 1.23.

c. They would have a mean of 3.3 and a standard deviation of 0.55.

For this problem, the mean is given by:

M = (2 + 3 + 2 + 3 + 3 + 4 + 2 + 4 + 3 + 2 + 2 + 7 + 3 + 4 + 5 + 3 + 3 + 3 + 3 + 5)/20 = 3.3

The standard deviation is:

[tex]S = \sqrt{\frac{(2 - 3.3)^2 + (3 - 3.3)^2 + \cdots + (3 - 3.3)^2 + (5 - 3.3)^2}{20}} = 1.23[/tex]

It states that for distribution of sample means of size n:

Hence, since 1.23/sqrt(5) = 0.55, the sample means would have a mean of 3.3 and a standard deviation of 0.55.

The surface area of the prism is 544 mm²

The formula is given thus;

SA=2B+ph

Where

B = area of the base

p = perimeter of the base

h = height

B = 1/2 h(b1+b2)

B = [tex]\frac{1}{2} * 8 * (17 + 9)[/tex]

B = 108 mm²

Perimeter = sum of length of sides

Perimeter = 17 + 9 + 15

Perimeter = 41 mm

Surface area = 2 ( 108 ) + 41 ( 8)

Surface area = 216 + 328

The value of x when y =4 is 2

An inverse proportion is represented as:

k = yx

Where

k represents the constant of proportion

When y = 2, x = 4.

So, we have:

k =2 * 4

k = 8

Substitute k = 8 in k = yx

So, we have:

Answer:

If f(-x) = f(x), f is even and is symmetric about y

If f(-x) = -f(x), f is odd and is symmetric about the origin

If [tex]f(-x)\neq f(x)[/tex] and [tex]f(-x)\neq -f(x)[/tex], f is neither even nor odd and does not have symmetry

Step-by-step explanation:

As we discussed in one of the previous questions, if f(-x) = f(x), we have an even function. One basic example of an even function is x^2 since (-x)^2 = x^2. On the other hand, if f(-x) = -f(x), we have an odd function. One common example is x^3 since (-x)^3 = -x^3. What we have not been over yet is the symmetry of the functions. In order to do this, let's examine x^2 and x^3. x^2, which is an even function, is symmetric to the y-axis. The graph is a parabola that looks exactly the same on the left and the right of the y-axis.

On the other hand, x^3, which is an odd function, is not symmetric to the y-axis. On the other hand, it is symmetric to the origin. You can imagine that if you flipped y = x^3 across the origin, you would end up getting a graph that looks exactly the same.

A function that is neither even nor odd, meaning [tex]f(-x)\neq f(x)[/tex] and [tex]f(-x)\neq -f(x)[/tex], one that is not odd or even, has no symmetry. It is not symmetric about the y-axis or the origin.

The initial value is 37,036 dollars and in 4 years, the value will be 18,439.16 dollars.

Here we have an exponential decay that models the value of a car as time passes, the exponential decay is:

[tex]v(t) = 37,036*(0.84)^t[/tex]

The initial value is what we get when we evaluate in t = 0.

[tex]v(0) = 37,036*(0.84)^0 = 37,036[/tex]

The initial value is 37,036 dollars.

The value in 4 years is what we get when we evaluate in t = 4:

[tex]v(4) = 37,036*(0.84)^4 = 18,439.16[/tex]

The solutions of the given quadratic equation is;  (1/4) + √7i/4 and  (1/4) - √7i/4

We are given the quadratic equation as;

2x² - x + 1 = 0

To solve this to find the root, we will use the quadratic formula which is given by;

x = [-b ± √(b² - 4ac)]/2a

Now, from the given quadratic equation, we can say that the values of a, b and c are;

a = 2; b = -1 and c = 1

Thus;

x = [-(-1) ± √((-1)² - 4(2 * 1))]/2(2)

x =  [1 ± √(1 - 8)]/4

x = [1 ± √(-7)]/4

x = (1/4) ± √7i/4

Thus;

x = (1/4) + √7i/4 and  (1/4) - √7i/4
