11) Is the following biconditional true? Explain. Two people are brother and sister if-and-only-if they are siblings.
Answer:
Well, not exactly.
Step-by-step explanation: You see, there's this thing called half siblings. They aren't exactly quite any different to normal siblings, except the fact that they either have the same mother and different father, or the same father and different mother. This usually results after a mother and a father divorce, or their respected love one dies, and they have children. The mother/father then can remarry, and when their wife/husband also has a child. The two or more children become half siblings. Also, if we're gonna talk not literal siblings. Close friends often like to think of each other as siblings, though they aren't biologically siblings. Half siblings and step sisters are two different things, half is where your sibling shares half your genes, and step siblings are where they don't have any of your genes and only their respected parent's genes. Now depending on if they mean biologically siblings, I would say true. But if they count all, then it would be false.i need it within tomorrow please
Consider the following sequence of successive numbers of the 2k
-th power:
1, 2
2
k
, 3

k

Show that the difference between the numbers in this sequence is odd for all k ∈ N.
Any even number raised to any power will remain even. (e.g. 2² = 4, 2³ = 8, etc)
Any odd number raised to any power will remain odd. (e.g. 1² = 1³ = ... = 1, 3⁴ = 81, etc)
So [tex](n+1)^{2^k}-n^{2^k}[/tex] will always be even, since both
[even] - [odd] = [odd]
and
[odd] - [even] = [odd]

Step-by-step explanation:
An amusement park opens daily at 9:30 a.m. This morning the parking lot for the amusement park opened at 8:00 a.m. At 9:00 a.m., there were 132 cars in the parking lot. The parking attendants noticed that every half hour between 9:00 a.m. and 10:30 a.m., the number of cars in the parking lot tripled. What type of function appropriately models this situation?
Answer:
An exponential function
Step-by-step explanation:
So let's suppose that at 9:00 am there were 132 cars. We'll call this [tex]P_0[/tex]
[tex]P_{0}=132[/tex]
On the next half an hour, let's say at 9:30, the number of cars trippled, this is:
[tex]P_{1}=132*3=396[/tex]
the next half an hour, at 10:00 am, the number of cars trippled, this is:
[tex]P_{2}=132*3*3=1188[/tex]
and finaly, at 10:30am, the number of cars trippled again, so:
[tex]P_{3}=132*3*3*3=3564[/tex]
We can now see a pattern there which can be simplified as:
[tex]P(n)=P_{0}(3)^{n}[/tex]
or
[tex]P(n)=132(3)^{n}[/tex]
where:
[tex]P_{0}=[/tex]initial number of cars
n=number of half hours after 9:00 a.m
[tex]P_{n}=[/tex] number of cars after n number of half hours.
That function we found there is an exponential function, which represents an initial amount being multiplied by the same number several times.

9:00 am

eight hot dogs at the baseball park cost $28. how much does one hot dog cost? (let h = price of hot dog)
Answer: $3.50
Step-by-step explanation:28/8=3.5
=3.50
Answer: h=3.50
Step-by-step explanation:28/8=h. This is the equation because in order to find the answer you must find the unit rate. In order to do so you grab the total cost and than the amount of something and divide them in order to find the answer.
What is the distance between points A = ( 1 , 4 ) and C = ( − 3 , 3.5 ) ?
Answer:
4.03units
Step-by-step explanation:
Distance between A and C=√(1--3)²+(4-3.5)²
=√(4)²+(.5)²
=√16+.25
=4.03units
The distance between points A = ( 1 , 4 ) and C = ( − 3 , 3.5 ) is 4.25 units.
What is distance formula?The distance between two points of the xy-plane can be found using the distance formula. The distance formula is:
√[(x₂ - x₁)² + (y₂ - y₁)²].
Now given coordinates of two points are,
A(1,4) and B(-3,3.5)
Therefore we have,
x₁ = 1
y₁ = 4
x₂ = -3
y₂ = 3.5
Now distance between A(1,4) and B(-3,3.5) = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(-3 - 1)² + (4 - 3.5)²]
= √[(- 4)² + (0.5)²]
= √16 +0.25
= 4 +0.25
= 4.25 units
Thus, the distance between points A = ( 1 , 4 ) and C = ( − 3 , 3.5 ) is 4.25 units.

Carolyn was asked to solve the following system of equations. Her work is shown.
Correctly find the solution to the system of inequalities. Show your work for credit.
Answer:
(11, 13)
Step-by-step explanation:
Given,
3x - 2y = 7 => (eqn. 1)
y = x + 2 => (eqn. 2)
Substitute y = (x + 2) in eqn. 1.
3x - 2(x + 2) = 7
Use -2 to multiply each term you have in the parentheses. (This is where Carolyn got it wrong)
3x - 2x - 4 = 7 (-2*4 = -4 not +4)
x - 4 = 7
Add 4 to both sides
x = 7 + 4
x = 11
Substitute x = 11 in eqn. 2.
y = x + 2
y = 11 + 2
y = 13
Solution: (11, 13)
Write the equation in slope-intercept form. 9x+3y=15 please show steps
Answer:
y = -3x + 5
Step-by-step explanation:
9x + 3y = 15
-9x -9x
3y = -9x + 15
y = -9x/3 + 15/3
y = -3x + 5

Find a solution to the system. Make sure to write as a coordinate.
Answer:
x=2, y=3
Step-by-step explanation:
This is a system of equations.
To solve a system of equations, we use the substitution method.
We can plug in the first equation, [tex]x=2y-4[/tex], into the value for x in the second equation. Now, the second equation looks like this:
[tex]2*(2y-4)+y=7[/tex]
We simplify and solve for y:
→ [tex]4y-8+y=7[/tex]
→ [tex]5y=15[/tex]
→ [tex]y=3[/tex]
Now, we plug in the value for y, which is 3, into either equation. I will just use the first equation:
→ [tex]x=2*3-4[/tex]
→ [tex]x = 2[/tex]

Question 12: H. Howard Hughes, Professor Emeritus of Texas Wesleyan
College, and his wife Erin Connor Hughes attended a record 6136
theatrical shows. Write an expression for the number of shows they
attended per year if they accumulated the record over "Y" years. *
Answer:
6136 / Y
Step-by-step explanation:
Total number of theatrical shows = 6136 shows
Total shows was attended over a period of Y years
Hence, number of shows attended per year:
(Total Number of shows / period of years between which shows was attended)
= 6136 / Y
