Answer: The change represents growth with 89% of growth rate.
Step-by-step explanation:
The exponential function is given by :-
... (i)
Where , A = initial value , b= multiplicative factor and x= time period
- We call 'b' growth factor when b>1, we can write b= 1+r , where r is the rate of growth.
- We call 'b' decay factor when b<1 , we can write b= 1-r , where r is the rate of decay.
The given function :
.
By comparing this to (i) , we get
b= 1.89 > 1 , thus it represent the growth.
Also,

i.e. Percentage rate of growth = 0.89 x 100 = 89%.
Simple, all you want to do is subtract. 7-2=5; and denominators are not subtracted thus it would be 5/8. And that is the simplest form already 5/8.
Your answer would be 4 you go with P.E.M.D.A.S so (5-1)= 4 then 4+4=8-4=4
Answer:
Step-by-step explanation:
PART 1
y=mx+b
m is slope and slope is 0 sooo
y=0x+b
it passes through (3,7)
7=0(3)+b
7=0+b
b=7
y=0x+7
so just y=7
PART 2
y=mx+b
y=1/5x+b
1/2=1/5(-2/3)+b
1/2=-2/15+b
1/2+2/15=b
15/30+4/30=b
19/30=b
y=1/5x+19/30
