Jose wants to put a fence around his rectangular garden. His garden measures 31 feet by 33 feet. The garden has a path around it

vlabodo [156]

3 feet width is added to both sides .
so the dimensions become 34 feet and 36feet
hence the fencing length required or the perimeter= 2(l+b)
= 2( 34+36)
= 2(70)
= 140feet fence

If two sides of a triangle measure 12 and 7, which cannot be the perimeter of the triangle?

ser-zykov [4K]

Hi,
Let assume x the 3th side.
x<12+7==> x<19
12<x+7==>x>5
So 5<x<19==> 5+7+12<x+7+12<19+7+12
==>24<x<38

Answer:

1.) Exponential Growth

2.) Exponential Decay

3.) Exponential Growth

4.) Exponential Decay

Step-by-step explanation:

1.) f (x) = 0.5 (7/3)^x

↓

always increasing

2.) f (x) = 0.9 (0.5)^x

↓

always decreasing

3.) f (x) = 21 (1/6)^x

↓

always increasing

4.) f (x) = 320 (1/6)^x

↓

always decreasing

EXPLANATION:

It's exponential growth when the base of our exponential is bigger than 1, which means those numbers get bigger. It's exponential decay when the base of our exponential is in between 1 and 0 and those numbers get smaller.
