The situation can be modeled by an exponential decay function with a percent change of -10%, option A is correct.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
The ratio between the value after 1 year and the value after 0 years is 18,000/20,000 = 0.9.
The ratio between the value after 2 years and the value after 1 year is 16,200/18,000 = 0.9.
The ratio between the value after 3 years and the value after 2 years is 14,580/16,200 = 0.9.
Since the ratio between consecutive values is constant and less than 1, we can conclude that the situation can be modeled by an exponential decay function.
r = (18,000/20,000) - 1 = -0.1
So the percent change per year is -10%, which means that statement A is true.
Hence, the situation can be modeled by an exponential decay function with a percent change of -10%, option A is correct.

how to solve 9x-5-(-6x)
Answer: 3x-5
Step-by-step explanation:
9x-5(-6x)
9x-5-6x
3x-5
Answer:
15x - 5
Step-by-step explanation:
We have the equation 9x - 5 - (-6x) and are asked to solve it.
We cannot combine 9x and 5 because they have a variable difference, with 9 having x as its variable and 5 having no variable. What we can do is distribute the minus sign to the right of 5 to (-6x), lets do as said :
9x - 5 - (-6x)
Two negatives make a positive, therefore :
9x - 5 + 6x
Since 9x and 6x have the same variable ending, we can combine them, do as followed :
9x - 5 + 6x
9x + 6x
15x - 5

hello your question has a missing diagram attached below is the missing diagram
answer :
Mark the point of intersection S of circles R and P, and construct line QS ( option 2 )
Step-by-step explanation:
when constructing a tangent line from one point ( lets say Q as seen in the question ) to a circle P. The next step should be to mark a point of intersection between the given circles and then construct a line through it
Answer:
Mark the point of intersection S of circles R and P, and construct line QS.
Step-by-step explanation:
This is correct because after you create circle R that intersects circle p, you're supposed to mark the intersection points. If your in FLVS, it would be in lesson 7.04. I also got this right on my test. Good luck!

Use the distributive property with factoring to find the equivalent expression. 24n + 32w = (3n + w)
Answer:
Step-by-step explanation:
24n + 32w = (3n + w)
We're asked to use distributive property, this means that we have to find a way that the given expression on the left hand side is equal to the given incomplete exresssion on the right hand side. In so doing, we're fulfilling the distributive property tag.
Given 3n, 3 factorises 24 into 8, and at the same time, factorises 32 into 4. Thus, we can then conclude that
24n + 32w = 8(3n + 4w)

Show work please! Herald is keeping track of eagles. To do so, he put tags on 25 eagles and released them.
Later, he catches 120 eagles; 16 eagles were tagged. Find the best estimate for the Eagle
population?
Answer:
188
Step-by-step explanation:
16/120=0.133
0.133 times 100=13.3%
this means 25 eagles is only 13.3% of the population
therefore 25/0.13=188
Gilbert purchased a car for 34000. The car depreciates at a rate of 14% per year. The exponential function that represents this situation is y = 34000(0.86)^x.
What is the change factor for this function?
Answer:
.86
Step-by-step explanation:
Exponential function formula
[tex]y = a ( 1 + or - r ) ^t[/tex]
where a = initial value
r = rate of change
and t = number of years
given the equation y = 34000(0.86)^x.
r = .86
Hence the change factor is .86

d = - [tex]\frac{9}{13}[/tex]
Answer:
d = -9/13Step-by-step explanation:
Given ,
13d + 8 = -1
=> 13d = -1 - 8

2/3 - 3/2y + 1/3y + 4 = 0
Answer:
y = 4
Step-by-step explanation:
(2/3 + 4) + (-3/2y + 1/3y) = 0
(-3/2y + 1/3y) = -4 2/3
-9/6y + 2/6y = -14/3
-7/6y = -14/3
cross-multiply:
-21y = -84
y = 4
Answer:
y = 4
Step-by-step explanation:
Please use parentheses for clarity, remembering what big differences they make in expression values.
I will assume that your "2/3 - 3/2y + 1/3y + 4 = 0" actually means
2/3 - (3/2)y + (1/3)y + 4 = 0
The LCD here is 6, which is the product of the denominators 2 and 3.
Then your "2/3 - 3/2y + 1/3y + 4 = 0" becomes:
4 - 9y + 2y + 24 = 0, which simplifies to:
28 - 7y = 0. Solving this, we get y = 4

Help how do I solve for x and y when they are they on the same corresponding side
Answer:
y = 33.94 mm
x = 19.80 mm
Step-by-step explanation:
Because AC = CB, then ∠ABC = 45°
cos ∠ABC = 24/y
cos 45° = 0.7071 = 24/y
y = 33.94 mm
EF/BC = x/y
14/24 = x/33.94
24x = 475.16
x = 19.80 mm
