hi guys can someone help me whit this question is for tommorow for my is so difficult . The exercise talks about math sets. It is: give three examples of sets A and B such that AU(union)B=B
Answers
Answer:
(i) A = {1}, B = {1, 2}, (ii) A = empty set, B = {1, 2, 3}, (iii) A = {a, b, c}, B = {a, b, c}, (iv) A = {7, 8, 9, 10}, B = {7, 8, 9, 10, 11, 12}
Step-by-step explanation:
The idea: A U B = the set of all elements (from a Universal set, like the set of all integers) that are in at least one of the sets A or B. So, for the equation A U B = B to be true, the set A must be a subset of the set B, because otherwise A U B would contain at least one element not in B, making the equation A U B = B false (set B would be a proper subset of A U B). So, if A = {1, 2, 3, 4} and B = {1, 2, 3}, then A U B = {1, 2, 3, 4}, and A U B = B would be false. However, if A = {1, 2, 3} and B = {1, 2, 3, 4}, then A U B = B would be true.

Answers
Answer:
Step-by-step explanation:
4:C(X) = 17x - 10, the first question wants you to find how much 5 ticket costs, so replace x with 5 so c(x)= 17(5)-10 which equals 75$
4a: 4a wants you to find how many tickets you can buy for 130$. So first replace the y or c(x) with 130 x, which gives 130=17x-10. Now we find x, first add 10 to both sides to cancel the -10, 140=17x, then divide 17 from both sides which gives 8.235, so we can buy 8 tickets.
4b: It is discreet because it cannot be broken down into decimals or fractions, since you cannot have a halve of a ticket.
4c: c(0) means the y-intercept

F(x) =?. Vertex is (2,-4) the other given point is (1,-2)
Answers
We could substitute these values into the vertex form of the quadratic function,
f(x) = a(x - h)^2 + k
where:
(h,k) is the vertex
The axis of symmetry is the vertical line x = 2
The value of “a” determines whether the graph opens up or down, and makes the parent function wider or narrower.
The value of “h” determines how far left or right the parent function is translated.
The value of “k” determines how far up or down the parent function is translated.
Now that we’ve established these definitions, we can substitute the given values into the vertex form:
f(x) = a(x - 2)^2 - 4
In order to determine the value of “a”, we must substitute the values of the other given point, (1, -2) into the equation:
f(x) = a(x - 2)^2 - 4
-2 = a(1 - 2)^2 - 4
-2 = a(-1)^2 - 4
-2 = a - 4
Add 4 to both sides to solve for “a”
-2 + 4 = a - 4 + 4
2 = a
Now that we have the value of a = 2, we can establish our quadratic function in vertex form:
f(x) = 2(x - 2)^2 - 4
I’m also including a screenshot of the graph of the function we came up with.

Answer:
The speed of the boat in still water is 12 miles per hour, while the speed of the current is 9 miles per hour.
Step-by-step explanation:
We'll use x as the speed of the boat in still water in miles per hour.
We'll use y as the speed of the current in miles per hour.
When the boat is traveling downstream, the speed of the boat is helped by the speed of the current and the net speed is x + y.
When the boat is traveling upstream, the current opposes the movement of the boat, and the net speed is x - y.
Using a table where d = distance in miles, r = rate or speed in miles per hour, and t = time in hours can help figure out how to figure out this problem.
─────────────────
Downstream│210│(x + y)│10
Upstream│210│(x - y)│70
─────────────────
Recall that distance = rate x time or d = rt.
210 = (x + y)10 ➤ Equation from downstream information.
210 = (x - y)70 ➤ Equation from downstream information.
210 = 10x + 10y ➤ Distribute.
210 = 70x - 70y ➤ Distribute.
7 × 210 = 7 × 10x + 7 × 10y ➤ Multiply the 1st equation by 7.
1470 = 70x + 70y ➤ Add the 1st equation to the 2nd.
210 =70x - 70y ➤ Add the 1st equation to the 2nd.
1680 = 140x
─────────────────
1680/140 = 140x/140
x = 12
210 = (12 + y)10 ➤ Substitute x = 12 into one of the original equations to find y.
210 = 120 + 10y
-120 - 120
90 = 10y
90/10 = 10y/10
y = 9

steve baked 5 1/2 batches of cookies in one and one half hours. Vondra baked 3 1/3 batches of cookies in 11/12 hour. Which baker made cookies at a greater rate of batches per hour?
Answers
Answer:
Step-by-step explanation:
Steve 11/2 batches / 3/2 hrs = 11/2(2/3) = 11/3 = 3 2/3 = 3 22/33 batches/hr
Vondra 10/3 batches / 11/12 hr = 10/3(12/11) = 120/33 = 3 21/33 batches/hr
Steve had a very slightly faster batch rate by only 1/33 batch/hr
In warmer climates, approximate temperature predictions can be made by counting the number of chirps of a cricket during a minute. The Fahrenheit temperature
decreased by forty is equivalent to one-third of the number of cricket chirps.
(a) Write an equation for this relationship.
(b) Approximately how many chirps per minute should be recorded if the temperature is 90°F?
(c) If a person recorded 72 cricket chirps in a minute, what would be the Fahrenheit temperature according to this formula?
(a) Let F represent the Fahreheit temperature and let x represent the number of chirps. The equation for this relationship is
(Use integers or fractions for any numbers in the expression.)
Answers
The relationship between temperature and the number of chirps based on the information given goes thus :
150 chips 64°F[tex] f - 40 = \frac{x}{3}[/tex]Let :
Temperature = f ; number of cricket chirps = n[tex] f - 40 = \frac{n}{3}[/tex]1.) Chirps per minute if temperature is 90°F
Put f = 40°F into the equation :
[tex] 90 - 40 = \frac{n}{3}[/tex]
[tex] 50 = \frac{n}{3}[/tex]
[tex] n = 50 \times 3 = 150 chirps [/tex]
2.) Fahrenheit temperature if n = 72
[tex] f - 40 = \frac{72}{3}[/tex]
Cross multiply
[tex] 3(f - 40) = 72[/tex]
[tex] 3f - 120 = 72[/tex]
[tex] 3f = 72 + 120 [/tex]
[tex] 3f = 192[/tex]
[tex] f = \frac{192}{3} = 64 [/tex]

For the first one, the left side of the equation would equal -6/3, and the left side would be 3/-6. When simplified it would be: -2 = -1/2, which is incorrect.
For the second one, the left side and the right side are the same because either way you put it, they are still being multiplied, and the order doesn't matter. The end result will be -72 = -72, which is correct.

Find the slope and y-intercept for this table.
Answers
Answer:
Slope is -5 and y-intercept is 90.
Step-by-step explanation:
Use the two values that you circles (4, 70) and (6, 60) .
slope (m) = the change in y-value/ (the change in the x-values).
m = (70 - 60)/(4 - 6) = 10/-2 = -5
The y-intercept is the value of "b" in the equation y = mx + b.
Using y = mx + b, substitute the value m and use point of your points (4, 70).
y = mx + b
70 = -5(4) + b Now solve for "b".
70 = -20 + b
+20 = +20
90 = b
