Step-by-step explanation:
The number of people in Pinellas country has been changing at a rate of 1.3% per year.
If in the year 2016, there were 960,730 people in the country and if x represents the number of years since 2016, then the function that models the number of people in the country after x years since 2016 is

Hello there.
Question: <span>Rory bought seven 3-packs of golf balls and five 20-pack of golf tees. How many golf items did he buy in all?
Answer: First you multiply the number of items in the pack by the number of packs bought.
7 x 3 = 21
5 x 20 = 100.
Add together the amount of items.
100 + 21 = 121.
In short, Your answer is Rory bought 121 golf items in total.
Hope This Helps You!
Good Luck Studying ^-^</span>
Answer:
80000 square meters
Step-by-step explanation:
perimeter + dividing fence = 800
let a = length
let b = width
let c = length of dividing fence
perimeter = 2*a + 2*b
let's say...
c is the same as the length
2a + 2b + c = 800
2a + 2b + a = 800
3a + 2b = 800
area = length*width
area = a*b
area / b = a
3*(area/b) + 2b = 800
3*(area/b) = 800 - 2b
area/b = (800 - 2b)
area = (800 - 2b)*b
To make the area large, we make the right hand side large.
800b - 2b^2
If you put in terms of x, y it looks like a downward opening parabola, so the max area is at the vertex. Half way between the roots.
y = -2x^2 + 800x
y = -x^2 + 400x
0 = x*(-x + 400)
roots are x= 0 and x = 400
vertex is at x, aka b = 200
area at b=200 is (800 - 400)*200 = 80000
and a is area/b... 80000/400 = 200
456÷12= 38
I pretty sure... I hope this helps!
