Answer:
Step-by-step explanation:
we know that
The equation of a exponential growth function is equal to
where
y is the average annual salary
x is the number of years
r is the rate of change
a is the initial value
In this problem we have
substitute
For x=4 years
The formula is
A=p (1+r)^t
A future value 6678
P present value 5300
R interest rate 0.065
T time?
6678=5300 (1+0.065)^t
6678/5300=(1+0.065)^t
Take the log for both sides
Log (6678/5300)=t×log (1+0.065)
Divide both sides by log (1+0.065)
T=(log(6,678÷5,300)÷log(1+0.065))
T=3.7 years

So how many of 5/8 wood pieces out of a 4 5/8 board
let's make the board size into a improper fraction so 8*4+5 = 37
so the board is 37/8
how many times can 5/8 go into 37/8
37/8 / 5/8
"Keep, change, flip" (for division of fractions)
keep the first number, change the sign into multiplication, and flip the last fraction
37/8 * 8/5
That is 7 2/5
Only 7 full 5/8 feet pieces of wood can be cut from a board that is 4 5/8 feet long (remainder 2/5)
Hope this helps :)
