The correct option is (A)
We have to find that :
Which table shows exponential decay
From the figure of exponential decay :
When the value of one variable of the function is decreased with increase in the number of other variable, then it is called the exponential decay function with constant exponential coefficient.
It can be given as,
[tex]\frac{dN}{dt}=-\lambda N[/tex]
Here, [tex]\lambda[/tex] is the exponential coefficient.
From Option A:
x y
1 16
2 8
3 4
4 2
The exponential coefficient for first and second row is,
[tex]\lambda=\frac{16}{8}=2[/tex]
Similarly,
[tex]\lambda=\frac{8}{4}=2\\\\\lambda=\frac{4}{2}=2[/tex]
Hence, as all the values of exponential coefficient is same, thus this shown the exponential decay.
From option B:
The exponential coefficient for first and second row is,
[tex]\lambda=\frac{16}{12}=\frac{4}{3}[/tex]
Similarly,
[tex]\lambda=\frac{12}{8}=\frac{3}{2} \\\\\lambda=\frac{8}{4}=2[/tex]

Micheal says their homes are elevations because they are in opposite directions Is he correct? Explain.
Answer:
Yes, Michael is correct. The elevation is measured in terms of sea level. Because Michael's home is 12 feet below sea level and his mother's home being 12 feet above sea level, their homes are at equally opposite directions.

Answer:
7a + b - 16c
Step-by-step explanation:
So we have
7a-3b+c-8c+4b-9c
When it comes to problem like these, you need to combine like terms.
There's only one 'a' number, so that one remains the same.
Next, we have -3b and 4b. (-3b+4b)= b
Finally, there's (c-8c-9c).
(-8c-9c)= -17c
Take that and add the positive 'c' to it.
(-17c+c)= -16c
Put it all together now to get:
7a + b - 16c

A cube is a special rectangular prism in which all the edges are the same length (like a square)
To find the volume of a cube given the height 6 just solve 6·6·6=216

Happy Paws charges $20.00 plus $3.50 per hour to keep a dog during the day. Woof Watchers charges $10.00 plus $4.75 per hour. Complete the equation and solve it to find for how many hours the total cost of the services is equal. Use the variable h to represent the number of hours.
Answer:
8 hours
Step-by-step explanation:
Create an equation that sets the costs equal to each other, where h is the number of hours
3.5h + 20 = 4.75h + 10
Solve for h
3.5h + 20 = 4.75h + 10
20 = 1.25h + 10
10 = 1.25h
8 = h
So, it will take 8 hours for the costs to be equal

Step-by-step explanation:
The figure shown is a parallelogram
The area of a parallelogram can simply be found by multiplying the base length and the height
We are given that the parallelogram has a height of 15 m and a base length of 11m
That being said the area is equal to 15 * 11
15 * 11 = 165
So the area of the parallelogram is 165 m²

• Which function is best represented by this graph?
A y = 1/4x+8
B y = 1/4x -2
C y = 4x -2
D y = 4x + 8
Answer:
B y=1/4x-2
Step-by-step explanation:
in y = mx + b
the b is the y intercept. this is where the line cuts through the y axis. you can see that it is going through the y axis at -2.
now look for your slope. I use rose over run. you can see that the line intersects at (4,-1)
"rise" is how far up or down to your next point."run" is how far left your right your next point is. in this case, the next point is 1 up and 4 to the right of a point. this translates to 1/4. this is a positive slope because your line goes upwards from left to right.

Answer:
slope: 1.25
Part B: The order in which the points are given does not change the value of the slope
Step-by-step explanation:
Part A. Given two points we can find slope using the slope formula
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Given the points ( -6, 1/2) and ( -4,3 )
We plug in the y values and x values (starting with the last point give )
[tex]m=\frac{3-.5}{-4-(-6)} \\3-\frac{1}{2} =2.5\\-4-(-6)=2\\\frac{2.5}{2} =1.25\\[/tex]
so we can conclude that the slope of a line that passes through the points ( -6, 1/2) and ( -4,3 ) is 1.25
Part B. The order in which the points are given does not change the value of the slope
Observe -
* flip the order in which the points are given *
given (-4,3) and (-6,1/2)
we use the same formula
*plug in the y and x values starting with the last point*
[tex]m=\frac{.5-3}{-6-(-4)} \\.5 - 3=-2.5\\-6-(-4)=-2\\\frac{-2.5}{-2} =1.25[/tex]
The slope still equals 1.25 meaning that the order in which the points are given does not matter.
In the system below, what is the value of k if x = 4? What is the solution to the system?
6x + 8y = k
x + y = 1
The system's solution is (xy, y) = and the k-value is 0. (4, -3).
What does the word "value" mean?Something that someone values are referred to as values. The things that only a person or a company considers "important" are, in other words, their values. Examples include valor, integrity, freedom, and inventiveness.
How do worth and value differ?Value includes both the material and emotional cost of that possession. Only the item's monetary price may be considered its worth. An object's value often remains constant, although it might change based on the person and how much the thing means to them personally.
If [tex]x = 4[/tex], then we can substitute [tex]4[/tex] for [tex]x[/tex] in the second equation to get:
[tex]4 + y = 1[/tex]
Subtracting [tex]4[/tex] from both sides, we get:
[tex]y = -3[/tex]
Now we substitute [tex]x = 4[/tex] and [tex]y = -3[/tex] into the first equation to solve for [tex]k[/tex]:
[tex]6x + 8y = k[/tex]
[tex]6(4) + 8(-3) = k[/tex]
[tex]24 - 24 = k[/tex]
[tex]k = 0[/tex]
Therefore, the value of [tex]k[/tex] is [tex]0[/tex], and the solution to the system is [tex](x, y) = (4, -3)[/tex]

Ryan's take-home pay is $2,500 each month. The amount for gas is $125. Calculate the percentage Ryan uses on gas from his take-home pay. please help!! O^O
Answer: 5%
Step-by-step explanation:
Since Ryan's take-home pay is $2,500 each month and the amount for gas is $125.
The percentage that Ryan uses on gas from his take-home pay will be:
= Amount used on gas / Take home pay × 100
= 125/2500 × 100
= 1/20 × 100
= 5%

Find the 75th term: 88, 81, 74, 67, 60
Answer:
a₇₅ = - 430
Step-by-step explanation:
There is a common difference between consecutive terms, that is
d = 81 - 88 = 74 - 81 = 67 - 74 = 60 - 67 = - 7
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 88 and d = - 7 , then
a₇₅ = 88 + ( 74 × - 7) = 88 - 518 = - 430
The 75th term of the arithmetic progression is -430
What is Arithmetic Progression?
An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"
The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is
Tn = a + (n - 1) d, where Tₙ = nth term and a = first term.
Here d = common difference = Tₙ - Tₙ₋₁
Sum of first n terms of an AP : Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]
Given data ,
Let the Arithmetic progression be = 88 , 81 , 74 , 67 , 60 ...
The first term of the AP is a ₁= 88
Now , the common difference of the AP d = second term - first term
= 81 - 88
= -7
Now , the nth term of the arithmetic progression is given by ,
Tn = a + (n - 1) d
Substituting the values in the equation , we get
T₇₅ = 88 + ( 75 - 1 ) ( -7 )
= 88 + 74 ( -7 )
= 88 - 518
= -430
Therefore , the value of T₇₅ is -430
Hence , The 75th term of the arithmetic progression is -430
