Answer:
7.
green blocks represent n
and normale digits (plus green) are orange
Anne: 1 orange block and increasing 2 green blocks from 2 sides
Sanjay: one line of green and orange line plus 1
Robert: 2 times the amount of green blocks on both lines with 1 orange block on right path
9.
a.y = 6x
b.y = 2^x
c.y = x+10
10.
a. 2 green blocks and 2 orange blocks
c. 3 green blocks and 1 orangle blocks
b. 4 green blocks
d.2 green blocks and 1 orange block
Step-by-step explanation:
for 10, it doesn't really matter
3x-7y=2 ; 3x=2+7y x=2x+7y/3
Answer:
(a) The future value after 9 years is $7142.49.
(b) The effective rate is 
.
(c) The time to reach $13,000 is 21.88 years.
Step-by-step explanation:
The definition of Continuous Compounding is
If a deposit of 
dollars is invested at a rate of interest 
compounded continuously for 
years, the compound amount is
(a) From the information given
Applying the above formula we get that
The future value after 9 years is $7142.49.
(b) The effective rate is given by
Therefore,
(c) To find the time to reach $13,000, we must solve the equation
(x,y)
to be a function
for every x, ther must be only 1 y to corespond to it
basically, x must NEVER repeat with a different y
list them
ah, we see (1,1) an d(1,-1)
also (4,2) and (4,-2)
double offense
1 repeats with 1 and -1
4 repeats with 2 and -2
not a function
domain is all x values
range is all y values
if they repeat, don't list them
domain=(0,1,4)
range=(-2,-1,0,1,2)
