the table represent some points on the graph of an exponential function which function represents the same relationship (see image attached)
Answers
Answer: Is the second
Step-by-step explanation:
I took the result of the tables of values with the calculator and it gave me the result I regret not being able to give you an explanation
The exponential function that represents the table is [tex]y =18 (\frac 65)^x[/tex]
An exponential function is represented as:
[tex]y = ab^x[/tex]
Where:
a represents the initial valueb represents the rateFrom the table we have the following ordered pair
(x,y) = {(0,18) (1,21.6)}
So, we have:
[tex]y = ab^x[/tex]
[tex]18 = a \times b^0[/tex]
[tex]a= 18[/tex]
Also, we have:
[tex]y = ab^x[/tex]
[tex]21.6 = a \times b^1[/tex]
[tex]21.6 = 18 \times b[/tex]
Divide both sides by 18
[tex]b = 1.2[/tex]
So, we have:
[tex]y =18 \times 1.2^x[/tex]
Rewrite as:
[tex]y =18 (\frac 65)^x[/tex]
Hence, the exponential function that represents the table is [tex]y =18 (\frac 65)^x[/tex]

The point (2, -7) is reflected across the x-axis.
What are the coordinates of the image of the point?
Answers
Answer: need more information
Step-by-step explanation: ....
The image of the point (2, -7) after reflection across the x-axis is (2, 7).
What is Reflection?In mathematics, reflection is a transformation that flips a figure over a line or plane. The line or plane is called the axis of reflection, and each point of the figure and its image are equidistant from the axis of reflection.
We have the coordinates as (2, -7).
Now, the rule for reflection across x- axis is
(x, y) -> (x, -y)
When a point is reflected across the x-axis, its y-coordinate is negated.
Therefore, the image of the point (2, -7) after reflection across the x-axis is (2, 7).

Devon scored 18 points in the first basketball game but 22 in the second game. What’s the percent of change?
Answers
Answer:
22.22%
Step-by-step explanation:
Well first let's find the difference between 22 and 18. 22 - 18 = 4. There's a 4 point difference, so now we need to find out how much 4 is of 18. 4 is 22.22% of 18.

Step-by-step explanation:
you move the 4p to the other side, making it negative,
- 4p + 19 = -5
then, you move the 19 to the other side, making it negative,
- 4p = -5 - 19
then you subtract,
- 4p = -24
divide by -4,
p = 6

2. The car is waiting at the starting point because the portion shows a constant function.
3. The car is traveling the same distance per unit of time because the portion shows a linear function away from the starting point.
4. The car stops a distance away from the starting point because the portion shows a constant function away from the starting point.

x=
Answers
Answer:
x = 22
Step by step solution:
5x+(3x-18)+x=180
Simplifying
5x + (3x + -18) + x = 180
Reorder the terms:
5x + (-18 + 3x) + x = 180
Remove parenthesis around (-18 + 3x)
5x + -18 + 3x + x = 180
Reorder the terms:
-18 + 5x + 3x + x = 180
Combine like terms: 5x + 3x = 8x
-18 + 8x + x = 180
Combine like terms: 8x + x = 9x
-18 + 9x = 180
Solving
-18 + 9x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + 9x = 180 + 18
Combine like terms: -18 + 18 = 0
0 + 9x = 180 + 18
9x = 180 + 18
Combine like terms: 180 + 18 = 198
9x = 198
Divide each side by '9'.
x = 22

Elsa took out a 2-year loan to buy a car at a 6% simple interest rate.
A. If she has to pay a total of $264 in interest, how much principal did she borrow to pay for the car?
B. How much did she end up paying for her car altogether?
Answers
Step-by-step explanation:
P = I / rt is the formula we're going to use.
P is the principle (which is what we're solving for)
I = the interest accrued over the specified amount of time (2 years)
r = the interest rate (6%)
t = the time specified (2 years)
Change the percent to a decimal. Place the decimal two places to the left to make 0.06.
P = 264 / 0.06(2)
P = 264 ÷ 0.12 = 2,200
Principal borrowed would be $2,200

Answer:
1) 9/20
2) 5/11
Step-by-step explanation:
For the first question: We read the number "0.45" as "45 hundredths," and we write it as the fraction 45/100. Of course, since 45 and 100 share the common factor 5, we can reduce this fraction by dividing the numerator and denominator by 5 to get the reduced form 9/20.
For our second problem, we need to perform a bit of "mathematical surgery" to find the appropriate fraction for x = 0.454545... First, the dots tell us that this fraction is repeating - those 45s will keep going on and on forever. When we multiply x by 100, then, we move the decimal two places to the right, but the repeating part still remains, giving us
[tex]100x=45.454545\dots[/tex]
From here, we can "surgically remove" the repeating bit using our original value of x:
[tex]100x-x=45.454545\dots-0.454545\dots\\99x=45[/tex]
And from here, we just have to divide both sides of the equation by 99 to solve for x:
[tex]99x=45\\x=45/99\\x=5/11[/tex]
