Answer:
Irrational
Step-by-step explanation:
Any non-zero rational number multiplied by an irrational number will be irrational. We can rewrite this as (8.57... * 5) / 8, but we have no idea how to make 8.57... * 5 rational, or expressed as the quotient of two integers.
We have been given that Jackson purchases a new car for $48,000. The car's value can be modeled by the following exponential function: 
where y represents the car's value and t represents time in years. We are asked to find the decay rate as a percentage.
We know that an exponential decay function is in form 
, where,
y = Final value,
a = Initial value,
r = Decay rate in decimal form,
x = time.
Upon comparing our given function with standard decay function , we can see that 
.
Let us solve for r.
Let us convert 0.24 into percentage.
Therefore, the decay rate is 24%.

sorry, i have to keep looking back at the photo
for the last question i will be solving ok
Go on the graph look at the y axis and x axis go to the x axis look for 2 and put the point and then go to postive 3 and put a point and that’s your answer.
Answer:
1. -3/6 is negative, because it descends by 3 and goes over by 6.
2. My first answer literally gives the keyword negative, therefore it's a negative line because it has a <em>negative slope</em>.
1. -8/0 is undefined, because there is a rise but there is no run, which also means that it's a:
2. vertical line
1. -5/-10 simplifies to 5/10 or 1/2, which is positive because it rises by 5(or 1) and runs over by 10(or 2).
2. Thus, this means that it's a positive line since it has a <em>positive slope</em>.
1. 0/-2 is zero, because when you actually solve the equation it'll equal 0.
2. This means that it'll have a horizontal line since there is no rise but there is a run only.
