Wouldn't it be 1/18x?????
<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:
5cm wide, 10cm long.
Step-by-step explanation:
I came to this answer by looking for common factors between 50 and 5, and I found 10.
5cm + 5cm = 10cm, so it works.
To confirm this, I multiplied 5 and 10 and got 50cm (squared) which works.
Answer:
32x + 80 = y (Question 10)
240 (Question 11)
