For this case we can make the following rule of three:
1/10 scarf ------> 4/5 hour
x ------------------> 1 hour
Clearing the value of x we have:
x = (1 / (4/5)) * (1/10)
Rewriting we have:
x = (5/4) * (1/10)
x = 5/40
x = 1/8
Answer:
A fraction of a scarf that alison can knit in 1 hour is:
x = 1/8
The average rate of change for a function over an interval is the slope
<h3>How to explain the steps?</h3>
Take for instance, we have the function to be
Function f(x)
And the interval is (a,b)
The average rate of change for the function over the interval is
Rate = (f(b) - f(a))/(b - a)
The above represents the slope
Take for instance, we have:
f(x) = x^2 [2, 4]
We have:
f(2) = 2^2 = 4
f(4) = 4^2 = 16
So, we have:
Rate = (16 - 4)/(4 - 2)
Rate = 6

Answer:
Hello! answer: 28.26
Step-by-step explanation:
You find circumfrence by doing diameter × pi or
radius × 2 × pi since we have are diameter this shall be a breeze 9 × 3.14 = 28.26 therefore the circumfrence is 28.26 hope that helps!
