Answer:
a) AUB = { 1 ,2 , 3, 4, 5, 6, 8, 10}
b) A∩ B = { 2, 4, 6 }
c) A-B = { 8 , 10}
Step-by-step explanation:
Step(i):-
Given that the sets
U = { 1,2,3,4,5,6,7,8,9,10}
A = { 2,4,6,8,10}
B = { 1,2,3,4,5,6}
AUB = { 2,4,6,8,10} U { 1,2,3,4,5,6}
AUB = { 1 ,2 , 3, 4, 5, 6, 8, 10}
Step(ii):-
A∩ B = { 2 ,4, 6, 8,10} ∩ { 1,2,3,4,5,6} = { 2, 4, 6 }
A-B = { 2,4,6,8,10} - { 1,2,3,4,5,6} = { 8 , 10}
Final answer:-
a) AUB = { 1 ,2 , 3, 4, 5, 6, 8, 10}
b) A∩ B = { 2, 4, 6 }
c) A-B = { 8 , 10}

Using the inverse composition rule you know that if (fog)=x and (gof)=x then the functions are inverses.
( g o f ) = ( 7 x + 1 ) − 1 7 this will result in (gof)=x ( f o g) = 7 x − 1 7 +1 = x − 1 + 1 =x
graphically you can check this if it seems that the functions are reflected over the line x=y.

A bacteria grows exponentially so that it doubles every 12 days. There are 500 bacteria initially. Write a function that models the number of bacteria after t days.
Note is is NOT doubling every day! Careful.
Find the number of bacteria after 60 days.
Answers
Answer:
16000 bacteria after 60 days
Step-by-step explanation:
60 divided by 12 = 5
500 x 2= 1000
1000 x 2 = 2000
2000 x 2 = 4000
4000 x 2 = 8000
8000 x 2 = 16000
The function is, f(x) = 2x/12*t
And, the number is 16000 bacteria after 60 days.
What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
here, given that,
A bacteria grows exponentially so that it doubles every 12 days
let, initially the number of bacteria = x
after 12 days = 2x
i.e. after t days = 2x/12*t
So, the function is, f(x) = 2x/12*t
Now, we have,
60 divided by 12 = 5
So, the number of bacteria will be,
500 x 2= 1000
1000 x 2 = 2000
2000 x 2 = 4000
4000 x 2 = 8000
8000 x 2 = 16000
Hence, the number of bacteria after 60 days is 16000.

Use the drawing tools to graph the solution to this system of inequalities on the coordinate plane.
y> 2x + 4
x+y s6
Answers
The inequalities y > 2x + 4 and x + y ≤ 6 can be plotted on the coordinate plane as shown in the picture.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have two inequalities:
y > 2x + 4
x + y ≤ 6
We can plot the above inequality on the coordinate plane.
The inequalities representing the region between the two lines the lines are:
y = 2x + 4
x + y = 6
y > 2x + 4 (dashed line on the graph)
x + y ≤ 6 (solid line on the graph)
Thus, the inequalities y > 2x + 4 and x + y ≤ 6 can be plotted on the coordinate plane as shown in the picture.

How do I Factor 42p⁴+9p³q²-18p²q²
Answers
Answer:
42p^4 + 9p^3q^2 -18p^2q^2 = p^2 (42p^2 + 9pq^2 - 18q^2)
Step-by-step explanation:
To answer this, we simply look for that term that is common to all
Looking at the given expression, we can see that the term we are looking for is p^2
Thus, we have that;
42p^4 + 9p^3q^2 -18p^2q^2 = p^2 (42p^2 + 9pq^2 - 18q^2)
When we multiply the term outside the bracket with each of the terms inside, we get back the original term

56 = -10 + 2x
Answers
Move the variable towards the left side and transition it’s sign in this problem
-2x+56=-10
Move the constant heading towards the right side and proceed to put a transition within it’s sign
-2x=-10-56
Now that you have that installed, you must calculate the difference here
-2x=-66
Now you divide -2 in both sides that has taken place in
x=33, therefore x=33 in 56=-10+2x
To check you can do 56=-10+2(33) and it will give you the right answer
Answer: x= 33
i subtracted -10 away from 56 and i got 66, then i divide 66 by 2x and got 33x.. which is your answer ;)

Vivian has a 550 page book on folk tales . If she reads 9 pages everyday before falling asleep . how many days will it take her to finish the book
Answers
Answer:
62 days
Step-by-step explanation:
Given that she reads 9 pages everyday before falling asleep. Then, on day one, she would read 9m pages.
On day 2, she would read another 9 pages, making 18 pages after 2 days. If she will finish the book in x days then
x = 550/9
=61 1/9 days
Converting the 1/9 into a day then, she will finish the book in 62 days, reading just a page on the 62nd day.
A combination lock has 7 digits. How many distinct combinations does this lock have if the numbers used have to be 0 through 5
Answers
Answer:
279,936
Step-by-step explanation:
Since there are 6 options for every digit, and seven digits
So,

The total number of distinct combinations for making 7 digits lock is 2,79,936.
What is permutation?A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters.
Formula for permutation with repetition:[tex]nP_{r} =n^{r}[/tex]
Where,
P is the total number of combinations.
n is the total number of items in a set
r is the total number of items to be selected from the set
According to the given question.
We have to form a lock that has 7 digits by using numbers from 0 to 5.
⇒ Total numbers of items in a set = 6
and total number of items to be selected = 7
Since, we have to form a lock of 7digits but we have only 6 digits. So we have to repeat this numbers so that we can form a 7 digit lock.
Therefore, the total number of combinations for making 7 digits lock is given by
[tex]6P_{7} = 6^{7}[/tex]
⇒[tex]6^{7}=2,79,936[/tex]
Hence, the total number of distinct combinations for making 7 digits lock is 2,79,936.
