<span>The answer would be: an = 10( one half )n − 1; average rate of change is </span><span>negative fifteen halves.
</span><span>This question is about exponent function/series. You are given 3 points from the function, point A (1,10), point B( 2, 5) and point C(4,1.25).
If you insert point A to the function, </span><span>an = 10( one half )^n − 1 </span>will give a result of 10 for n=1.
For n=0, the result would be:
an = 10( one half )^n − 1
an= 10(1/2)^0-1
an= 10(1/2)^-1= 10* 2= 20
Then the average rate of change from n=0 to n=2 would be:
Rate of change= (y2-y1)/ (x2-x1)
Rate of change= (5-20)/ (2-0)= -15/2= <span>negative fifteen halves</span>

Answer:
1434.375
Step-by-step explanation:
If you multiply 1,800 by 25% you get 1,350
you take 1,350 and add 6.25% because the 6.25% is the tax.
Then you will get 1434.37 or 1434.40
No. The amount is getting larger when you increase by 50% therefore 50% of the new number is larger than 50% of the original. When you decrease by the new 50% it will be less than the original.
For example, say your amount is 12. 50% of 12 is 6.
If you increase by 50%, your new amount is 18.
50% of 18 is 9.
Decreasing by 9 is 9, which is not equal to 12.
25,460 • 10 = 254,600
you can just move the zero over one spot since 10 has one zero
