3. Which situations can be represented by an exponential function?
Select each correct answer.
The value of a motorcycle decreases by 12% each year.
In a structure made of soup cans, each row has 6 more cans than the previous row.
Every year, the number of online subscribers to a service is 4 times what it was the previous year.
A doctor's office accepts 20 new patients each month.
Answers
Answer:
Question 1) Is option C: 2. (Question 2) The correct answer is 1.09 for the K12 program. Question 3) Option A: The value of a motorcycle decreases by 12% each year. (Option C) Every year, the number of online subscribers to a service is 4 times what it was the previous year.
The ratio of outputs for any two inputs that are one value apart is 4 thus option (A) is correct. The ratio of outputs for any two inputs that are two values apart is 1/8. The situation in option (3) represents the exponential function.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given table,
The ratio of outputs for any two inputs that are one value apart = (-1/2)/(-1/8) = 4
The ratio of outputs for any two inputs that are two values apart = (-1/8)/(-1) = 1/8
Every year, the number of online subscribers to a service is 4 times what it was the previous year's exponential function with a 4^x exponent.
Hence "The ratio of outputs for any two inputs that are one value apart is 4. The ratio of outputs for any two inputs that are two values apart is 1/8 and the third statement shows exponential function".

To encourage new customers, a movie theater is offering different ways to pay for the movie.
Members pay a one time fee of $75 and then $2 per movie they watch.
Non-members pay $5.75 per movie they watch.
Answers
Answer:
Number of movies for equal wage = 20
Step-by-step explanation:
Assume;
Number of movies for equal wage = x
So,
75 + 2x = 5.75 x
3.75 x = 75
x = 75 / 3.75
x = 20
So,
Number of movies for equal wage = 20

The actual area of the room will be 23.52 m².
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Width of room = 4 cm
Length of room = 12 cm
And, The scale model uses a scale in which 2 centimeters represents 1.4 meters.
Now,
Since, The scale model uses a scale in which 2 centimeters represents 1.4 meters.
That is,
2 cm = 1.4 m
1 cm = 0.7 m
So, The width of room = 4 cm
= 4 x 0.7 m
= 2.8 m
And, The length of room = 12 cm
= 12 x 0.7 m
= 8.4 m
Thus, The actual area of room = Length x Width
= 8.4 x 2.8 m²
= 23.52 m²
Therefore, The actual area of the room will be 23.52 m².

9 is obtuse but 8 is acute
2 and 4 are acute.
Step-by-step explanation:
I believe this is correct.
A right angle is a perfect corner. Think of a square and look at the corner, it doesn't go farther or shorter when it hits a side if you know what I mean by that. An acute angle is shorter than a right angle, or stops before it can be called a right angle. An obtuse angle is bigger than a right angle, or ends after the right angle point. I hope what I have just said here helps you with future problems!! Good luck :))
can someone please solve this 5+2x=7+3x
Answers
Simplifying
2x + -7 = 3x + 5
Reorder the terms:
-7 + 2x = 3x + 5
Reorder the terms:
-7 + 2x = 5 + 3x
Solving
-7 + 2x = 5 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-7 + 2x + -3x = 5 + 3x + -3x
Combine like terms: 2x + -3x = -1x
-7 + -1x = 5 + 3x + -3x
Combine like terms: 3x + -3x = 0
-7 + -1x = 5 + 0
-7 + -1x = 5
Add '7' to each side of the equation.
-7 + 7 + -1x = 5 + 7
Combine like terms: -7 + 7 = 0
0 + -1x = 5 + 7
-1x = 5 + 7
Combine like terms: 5 + 7 = 12
-1x = 12
Divide each side by '-1'.
x = -12
Simplifying
x = -12
The proportion 75/w = 150/100 can be used to find the whole 'w' when the part is 75. Will the 'w' be less than or greater than 75? Without solving, explain how you know. *
Answers
Answer:
w will be less than 75.
Step-by-step explanation:
Given the expression;
75/w = 150/100
We are to determine whether w is greater than or less than 75.
If you look at the right hand side of the expression, 150/100, you will see that the denominator is greater than the numerator. Due to the equality sign between the fractions, the same will be applicable to 75/w meaning that w will also be less than 75.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number be = A
Now , the equation will be
A number divided by 43 has a quotient of 3 with 28 as a remainder
So , A / 43 = 3 + 28/43 be equation (1)
On simplifying the equation , we get
A / 43 = 3 + 28 / 43
A/43 = ( 3 x 43 + 28 ) / 43
Multiply by 43 on both sides of the equation , we get
A = 3 x 43 + 28
A = 129 + 28
A = 157
Therefore , the value of A is 157
Hence , The number when divided by 43 has a quotient of 3 with 28 as a remainder is 157

In short, you had it flipped, always put your smallest value first and your largest value second.
Reason:
Interval notation is

Which is basically saying the minimum and the maximum, and as such you always end up having the smallest value first.
Putting the reasoning together;
A negative is always less than a positive in practice, therefore, your negative infinity should go first.
