Answer:
1.) Exponential Growth
2.) Exponential Decay
3.) Exponential Growth
4.) Exponential Decay
Step-by-step explanation:
1.) f (x) = 0.5 (7/3)^x
↓
always increasing
2.) f (x) = 0.9 (0.5)^x
↓
always decreasing
3.) f (x) = 21 (1/6)^x
↓
always increasing
4.) f (x) = 320 (1/6)^x
↓
always decreasing
EXPLANATION:
It's exponential growth when the base of our exponential is bigger than 1, which means those numbers get bigger. It's exponential decay when the base of our exponential is in between 1 and 0 and those numbers get smaller.

Determine whether the values in the table represent a direct variation. If yes, write an equation to represent the relationship.
Answers
Answer:
No
Step-by-step explanation: No unit rate
Answer:
no
Step-by-step explanation:
there is no direct variation the changes in both x and y are not constant. In y, it is first 62 then it becomes 140. The change here is 78. However, for the next two numbers ( 140 and 256), the change should also be 78. That's how you would know that it is constant and represents a direct variation. But in this case it isn't.

- As x increases, y _______ (increases/decreases).
- The rate of change for y as a function of x is not __________ (constant/constant), therefore the function is ________ (linear/nonlinear).
- For all values of x, the function value y ___ (≤/≥/=) 0.
- The y-intercept of the graph is the function value y = ____.
- When x = 1, the function value y = ___.
Answers
Answer: As "x" increases "y" *decreases*
y as a function of x is not *constant*
Therefore the function is *nonlinear*
For all values of x, the function value y *≥* 0.
The y intercept of the graph is *8*
x=1 function value of y is *5*
The given function is an exponential function and its qualities are explained below.
What is a logarithmic function?The opposite of an exponential function is a logarithmic function. A log function and an exponential function both use the same base. An exponent is a logarithm. f(x) = bx is how the exponential function is expressed. The formula for the logarithmic function is f(x) = log base b of x.

You need 112 K-cups for a party. A box of K-cups costs $16 for 36 K-cups. What is the minimum amount of money you will spend?
Answers
Answer:
$49.60
Step-by-step explanation:
The equation setup I used for this was as follows: $16 x (112/36)
Using PEMDAS, you'd start with the division part, 112/36. Although, I did this a bit differently, and being a bit further in school, I don't know if you go through this where you're at.
Start by factoring 112 into 4(28). This leaves you with 4(28)/36.
Next, cancel 4 out of 36. Since 4 is the common factor in 28 and 36, you cancel the four out of the equation, leaving you with 28/9. Convert this to its decimal form, 3.1.
Finally, take the 3.1 and multiply that by $16, which comes out to $49.60.

The bar below is 7 inches long and divided into 2 equal parts.
What is the length of one of those parts?
Fill in the blanks in the equation using fractions or mixed numbers
to show the length of one of the parts.
X 7 inches = inches
Answers
Answer:
The length of each part is 3.5 inches.
Step-by-step explanation:
The question states that the bar is 7 inches long, with the two parts being equal lengths.
What you would do to find the length of each bar is doable with simple division. Take 7, and divide it by 2. 2 goes into seven 3 times, which would leave 1. Add a decimal and a zero, bring the zero down, and you get 10. 2 goes into 10 five times, giving you the 5 in 3.5.
1/2×7=3.5 inches is the equation which gives the length of the one of the part of bar.
What is Area of Rectangle?The area of Rectangle is length times of width.
Given that the bar is 7 inches long and divided into 2 equal parts.
We need to find the length of one of those parts.
We take the whole bar as a whole number.
The two parts of the bar are considered as parts of the bar.
The seven inches is divided equally.
The length of the bar is seven inches.
We need to divide seven by two to get the length of one part.
When seven is divided by the two we get three point five inches which is the length of the one of the part of the bar.
1/2×7=3.5 inches
The equation which gives the length of the one of the part of bar is 1/2×7=3.5 inches.
Hence, 1/2×7=3.5 inches is the equation which gives the length of the one of the part of bar.
