Answer:
■ A random sample of dogs at different animal shelters in Abu Dhabi shows that 12 of the 60 dogs are puppies. Abu Dhabi's animal shelters collectively house 1,200 dogs each year. About how many dogs in all of the city’s animal shelters are puppies?
➢12/60 are puppies. 60 are the number of dogs, 12 is number of puppies.
If there are 1200 dogs, we focus on the 60. 1200/60= 20
Whatever we do to the denominator we do to the numerator, so since we can multiply 60 by 20 to get 1200; we need to multiply 12 by 20 to get the total number of dogs. Which is 240.
60/1200 = x/20 1200x /1200 =12/20 x =240

Answer:
The everage rate of change over the interal 4 ≤ x ≤ 8 will be: 60
Step-by-step explanation:
Given the function
Interval : 4 ≤ x ≤ 8
or
Interval = [4, 8]
so
at x₁ = 4, f(x₁) = 2ˣ - 12 = 2⁴ - 12 = 16-12 = 4
at x₂ = 8, f(x₂) = 2ˣ - 12 = 2⁸ - 12 = 256 - 12 = 244
Using the formula to determine the average rate of change over the interval 4 ≤ x ≤ 8 wil be:
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [244 - 4] / [8-4]
= 240 / 4
= 60
Therefore, the everage rate of change over the interal 4 ≤ x ≤ 8 will be: 60
