Work Shown:

A = set of multiples of 3 between 1 and 16

A = {3, 6, 9, 12, 15}

B = set of even natural numbers up to and including 20

B = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20}

A u B = {3, 6, 9, 12, 15,       2, 4, 6, 8, 10, 12, 14, 16, 18, 20}

A u B = {2, 3, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20}

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

Explanation:

The U stands for "set union". It's where we combine two or more sets together to form a larger set. The duplicates are tossed out. This is what your teacher meant when writing "Make sure each element is only listed once". Writing A u B indicates "the set of values in either set A, set B, or both".

In this case, the duplicates are "6" and "12" since they are found in set A and B simultaneously. They are in the overlapped area of both sets. It might help to draw out a Venn Diagram.

Common convention is to sort the items in the set. Though technically a set like {1,2,3} is the same as {3,1,2}.

Don't forget about the curly braces to indicate to the reader that this is a set of values.

After 15 years, Zephan will have a balance of $13181.07 in his savings account.

Given,

In the question:
Compound Interest is given by the formula.

A = P(1 + r)^t

Zephan invested $5500 in a savings .

Rate of interest is 6%

Time = 15 years

Now, According to the question:

We know that :

P = 5500

r = 6%

n = 1

t = 15

Compound Interest is given by the formula.

A = P(1 + r)^t

Substitute the values in above formula.

A = 5500. [tex](1+\frac{6}{100}/1 )^1^5[/tex]

Evaluate the equation/expression:
A = 13181.070062

Round 13181.070062 to the required place

= 13181.07

Hence, After 15 years, Zephan will have a balance of $13181.07 in his savings account.

The graph of f(x) is transformed 6 units horizontally to get the graph g(x). g(x) is a transformation form of the graph of f(x).

What is the reciprocal function?

The typical instance of reciprocal functions that we might run into is y = a/x, where a is a real number. Accordingly, reciprocal functions are those that have an algebraic expression in the denominator and a constant on the numerator.

Given functions are:

f(x) = -1/(2x-5)

g(x) = f(x-3)

The points on the graph f(x) = -1/(2x-5) are:

When x = 0, f(x) = 1/5

When x = 1, f(x) = 1/3

When x = -1, f(x) = 1/7

The graph of f(x) is added.

Putting x = x-3 in f(x) = -1/(2x-5) to find the function g(x):

g(x) = -1/(2x-6-5)

g(x) = -1/(2x-11)

The points on the graph g(x) = -1/(2x-11) are:

When x = 0, g(x) = 1/11

When x = 1, g(x) = 1/9

When x = -1, g(x) = 1/13

The solution of the differentiated equation is dy/dx = 40x³+ 3

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

Y=10 x^4+3 x+50

Rewrite properly

So, we have

y = 10x⁴ + 3x + 50

The rule of first principle of differentiation is represented as

If y = axⁿ, then dy/dx = naxⁿ⁻¹

Using the above as a guide, we have

dy/dx = 4 * 10x⁴⁻¹ + 1 * 3x¹⁻¹ + 0 * 50

Evaluate

dy/dx = 40x³+ 3

Hence, the equation result is dy/dx = 40x³+ 3

The required amount after 3 years is $1090, but when compounded annually the amount becomes $1092.72.

Given that,
$1000 become in a saving account at 3% per year for 3 years when the interest is not compounded.

Simple interest is defined as the percentage of earning on the lending for a period of time

Here,
Simple interest earned = P × r × t /100
                                      = 1000 × 3 × 3 /100 = 90
Amount = P + SI = 1000 + 90 = $90
Now, when interest is compounded annually,
Amount =  1000(1.03)³
Amount = $1092.72

Thus, the required amount after 3 years is $1090, but when compounded annually the amount becomes $1092.72.

The probability that they two people are chosen and travel by different transport is 47/144

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen.

Probability is given as sample space / total outcome

Probability to travel by car p(C)= 5/12

Probability to travel by bus P(B)= 4/12=1/3

Probability to travel by train P(T)= 3/12= 1/4

for two people chosen at random

P(C ×B)= 5/12×1/3= 5/36

P(B×T)= 1/3×1/4= 1/12

P(C×T)= 1/4×5/12= 5/48

Therefore the probability that the two chosen travel by different car is

P(C ×B)+P(B×T)+P(C×T)= 5/36+1/12+5/48

= 141/432

The value of a³ + b³ is 64.184

Here,

a + b = 5 .........(1)

and ab = 6

a = b/6

Substitute above value of 'a' in equation(1)

b/6 + b = 5

7b/6 = 5

7b = 30

b = 30/7

b = 4.28

So, a = 5 - 4.28

a = 0.72

We know that the formula of a³ + b³

a³ + b³

= (a + b)(a² + b² - ab)

= 5 * (0.72² + 4.28² - 6)

The explorer stood 2.63m away from the flag pole.

The angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.

If the pole is 3m high, and his eye is 1.6 meters from the ground.

Then distance from the top of the pole and his eyes  would be 3 - 1.6 = 1.4m

The angle of elevation between the line of sight and the horizontal = 28°

so the horizontal, angle of elevation and the distance between sight and top of pole form a right angle triangle.

Let the distance of the explorer from foot of pole be x,

so that,

tan 28 = 1.4/x

by cross multiplying,

x tan28 = 1.4

x = 1.4/tan28

x = 1.4/0.5317

x = 2.63m
