Answer:
Given the table as shown below:
x y
-3 8/27
-2 8/9
-1 8/3
0 8
1 24
2 72
3 216
Taking any input variable x that are three apart:
i,e x = 0 and x = 3
The output values at x =0 and x = 3 are:
f(0) = 8 and f(3) = 216
Then;
The ratio of outputs is:
[tex]\frac{f(3)}{f(0)} = \frac{216}{8}= \frac{27}{1}[/tex] or 27 : 1
Therefore, the ratio outputs for any two inputs that are three values apart is: [tex]27: 1[/tex]

We are given that AB ≅ CB and AD ≅ CD.
We know that BD ≅ BD, so ΔABD ≅ ΔCBD by SSS.
Then ∠1 ≅ ∠2 by CPCTC; and ∠3 ≅ ∠4, also by CPCTC.
Since ∠1 ≅ ∠2, BD is the bisector of (∠1+∠2) = ∠ABC.
Since ∠3 ≅ ∠4, BD is the bisector of (∠3+∠4) = ∠ADC.
6.From (5), we know BD is the angle bisector of ∠ABC. ΔABC is isosceles, so the bisector of the apex angle is also an altitude and median. That is, point M on BD and AC must be the midpoint of AC by the definition of a median.
Which of the following values of x makes the rational expression below undefined?
Problem : 16-x/7+x
A. 7
B. -7
C. 16
D. -16
Answer: The correct option is (B) -7.
Step-by-step explanation: We are given to select the correct values of x that make the following rational expression undefined :
[tex]E=\dfrac{16-x}{7+x}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We know that
a rational expression is undefined at the points where the denominator becomes zero.
Therefore, the expression (i) will become undefined when
[tex]7+x=0\\\\\Rightarrow x=-7.[/tex]
Thus, the required value of x where the given expression is undefined is -7.
Option (B) is CORRECT.

A museum gift shop manager wants to put 1,578 polished rocks into small bags to sell as souvenirs.If the shop manager wants to put 15 rock in each bag,how many complete bags can be filled?How many rocks will be left over
The number of bags that can be filled completely is 105 and the 3 rocks will be left over.
What is division?Division is the process of dividing a number by a given number.
Given that, the number of rocks is 1578 and the number of rocks in each bag is 15.
To find the number of bags, divide the number of total rocks by the number of total rocks in each bag:
1578/15
= 105.2
≈ 105
Now, the number of rocks in 105 bags is:
105 ×15
= 1575
So, the number of rocks left is:
1578 - 1575
= 3
Hence, the number of bags that can be filled completely is 105 and the 3 rocks will be left over.

The game room of the youth center needs carpet. The room measures 3 feet by 2 feet on the blue print. If the scale on the blue print 1 foot to 5 yards,what is the actual length of the game room?
Answer:
The actual room measurement is 15 yrds by 10 yrds
Then the length is 15 yrds
Step-by-step explanation:
1 feet is equal to 0.3333 yards
The room measure 3 by 2 feet
Scale on blue print 1 ft to 5 yrds.
That's is to say for every ft in the Blue print...it is 5 yrds real.
So it's multipling factor bis five.
The actual measurement will be
5*(3 by 2) yrds
The actual measurement is 15 yrds by 10 yrds .
But the length is 15 yrds and breadth is 10 yrds
Which expression is equivalent to the square root of -80?
Answer:
sqrt(-80) = 4sqrt(5)i
Step-by-step explanation:
Likely a list of answers should be provided. There are all kinds of possible answers (well 2 perhaps).
Begin by factoring 80 into prime factors.
80: 2*2*2*2*5
For ever pair of 2s, one can be taken outside the square root sign. The other one just disappears.
sqrt(80) = sqrt(2 * 2 * 2 * 2 * 5)
For every pair 2 is taken out of the root sign and the other forgotten
sqrt(2 * 2 * 2 * 2 * 5) = 2 * 2 * sqrt(5) = 4 sqrt(5)
The sqrt(-80) = 4sqrt(5)*sqrt(-1)
There is no real number that can be written as the sqrt(-1). So a number has been defined into existence. sqrt(-1) = i It's a definition, not a real number.
So the end result is sqrt(-80) = 4sqrt(5)i

Ryan has three sticks of lengths 6 inches, 10 inches, and 8 inches. He wants to join the three sticks to form a right triangular base for a model. Discuss whether these sticks form a right triangle. EXPLAIN
Answer:
yes
Step-by-step explanation:
for the sticks to form a right triangle, the 3 sticks' lengths must comply w the Pythagoras theorem: hypothesis^2 = first side^2 + second side^2
hypothesis is the longest length so its 10
10^2 = 100 = 36 + 64 = 6^2 + 8^2
so the 3 sticks will form a right triangle
Answer:
6^2+8^2=10^2 so yes
Step-by-step explanation:
In order to test a triangle with lengths 6, 8 and 10 inches is right-angle or not, the Pythagoras equation should be used: a^2+b^2=c^2.
As 6^2+8^2=10^2 so yes, the three sticks will form a right-angle triangle.

Joey chestnut is trying to break his own world record for eating the most hot dogs and buns in 10 minutes. He needs to eat more than 72 hot dogs to break his record. After 1 minutes of competition, Joey has eaten 10 hot dogs. Joey wants to know the number of hot dogs per minute that he need to eat for the next 9 minutes to break his own record.
Answer:
Joey needs to eat 7 hot dogs per minute to break his own record in next 9 minutes.
Step-by-step explanation:
Joey needs more than 72 hot dogs in 10 minutes to break his own record.That means Joey needs to eat at least 73 hot dogs in 10 minutes.
After 1 minute Joey has eaten = 10 hot dogs.
In remaining 9 minutes balance hot dogs = 73-10 =63
Therefore per minute hot dogs to be eaten = 63/9 =7
So answer is 7 hot dogs per minute to be eaten.
Joey needs to eat 7.00 hot dogs per minute for the next 9 minutes to break his own record.
To break his record, Joey Chestnut needs to eat more than 72 hot dogs in 10 minutes. After the first minute, he has already eaten 10 hot dogs. So, he has 9 minutes left to eat the remaining hot dogs needed to break the record, which is 72 - 10 = 62 hot dogs.
To find out how many hot dogs per minute Joey needs to eat for the next 9 minutes, we divide the remaining number of hot dogs by the remaining time:
Hot dogs per minute = Remaining hot dogs / Remaining time
Hot dogs per minute = 62 hot dogs / 9 minutes
Hot dogs per minute ≈ 6.89 hot dogs per minute
Therefore, Joey needs to eat 7.00 hot dogs per minute for the next 9 minutes to break his own record.
It's important to note that Joey needs to eat more than this calculated rate per minute to ensure he breaks his record, as he cannot consume a fraction of a hot dog. So, he should aim to eat at least 7 hot dogs per minute to secure his victory.

The rectangle below has an area of x^2-6x-7x 2 ?6x?7 square meters and a width of x-7x?7 meters. What expression represents the length of the rectangle?
Answer:
[tex]x+1[/tex] meters.
Step-by-step explanation:
Let L be the length of rectangle.
We have been given that the rectangle has an area of [tex]x^{2}-6x-7[/tex] square meters and a width of [tex]x-7[/tex] meters.
Since we know that area of rectangle is the product of its length and width.
[tex]\text{Area of rectangle}=\text{Width* Length}[/tex]
[tex]\text{ Length}=\frac{\text{Area of rectangle}}{\text{Width}}[/tex]
To find the length of our given rectangle we will divide area of rectangle by width of our rectangle.
[tex]L=\frac{x^2-6x-7}{x-7}[/tex]
Let us factor out our numerator by splitting the middle term.
[tex]L=\frac{x^2-7x+x-7}{x-7}[/tex]
[tex]L=\frac{x(x-7)+1(x-7)}{x-7}[/tex]
[tex]L=\frac{(x-7)(x+1)}{x-7}[/tex]
Upon cancelling out x-7 from numerator and denominator we will get,
[tex]L=(x+1)[/tex]
Therefore, the length of our rectangle will be [tex]x+1[/tex] meters.
