Answer:
Rate of change = -1
Step-by-step explanation:
Given:
f(x) = -½(x + 2)² + 5
Required:
Average rate of change from x = -3 to x = 1
Solution:
Rate of change = 
Where,
a = -3,
f(a) = f(-3) = -½(-3 + 2)² + 5 = -½(-1)² + 5 = 4.5
b = 1,
f(b) = f(1) = -½(1 + 2)² + 5 = -½(9) + 5 = 0.5
Plug in the values into the formula:
Rate of change = 
Rate of change = 
Rate of change = -1
The answer is rotation and this is a sure that its a rotation
For this case we have that by definition, a direct variation is given in the form:
Where:
k: It is the constant of proportionality
According to the statement we have to:
Substituting:
On the other hand we have:
Answer:
Answer:
12/7
Step-by-step explanation:
1 x 7= 7, then add 5 because of the denominator. 12/7
1680. 8p4, which is 8!/(8-4)!
