4. 8g+8h-16
Answer:
Part A) 
Part B) 
Step-by-step explanation:
Part A) What is the explicit rule for the number of residents
we know that
In this problem we have a exponential function of the form

where
a is the initial value
b is the base
r is the rate
(1+r)=b
so
Let
y ----> the number of residents
x is the time in years
we have
a=1,000 residents
r=1%=0.01
b=(1+0.01)=1.01
substitute

Part B) How many residents will there be in the town in Year 10?
For x=10 years
substitute in the equation


What are the expressions?? is there suppose to be options or diagrams??
Linear, because the points (1,8) (2,6) (3,4) etc are decreasing at a constant rate of -2.
Juan will jump 40 times in 50 seconds.
The unitary method is a concept wherein a problem is solved first by finding the value of a single unit and then multiplying the single unit value to find the necessary answer.
Here, we are given that
Juan jumps 24 times in 30 seconds
Thus, the number of times he will jump in 1 second is given by-
24/ 30 = 0.8
Thus, he jumps 0.8 times in 1 second
Now, we need to find the number of times he jumps in 50 seconds. We can do so simply by multiplying the number of times he jumps in 1 second by 50.
Thus, number of times he jumps in 50 seconds = 0.8 * 50
= 40
Therefore, Juan jumps 40 times in 50 seconds.
