Length(l)= 2w
Width(w)= w
Area(A) = l*w
A= 128 ft²
128= l*w
128= (2w)w
2w²= 128
w²= 64
w=√64= 8 ft
w= 8 ft
length(l)= 2w
l=2(8)
l=16 ft
P= 2l+2w
P=2(16)+2(8)= 32+16= 48ft
P= 48ft

Answer:
The expression provided by the area (square meters) is given by: 
.
Step-by-step explanation:
The area of the algae colony is a function of the radius r (meters), so 
.
The radius of the circle formed by the algae colony is a function of time t (in minutes), so 
. So,
[Substituting the expression for radius]
Then the expression provided by the area (square meters) is given by: .
Answer:
-3
Step-by-step explanation:
Because slope is rise over run.
Rise = -3
Run = 1
Rise/Run = -3/1 = -3
Answer:
The total amount of interest Samantha will pay=$40,842.47
Step-by-step explanation:
Step 1: Determine expression of total interest amount to be payed
The expression for the total interest amount to be payed inclusive of interest is given by;
A=P(1+r/n)^(nt)-P
where;
A=total amount of interest to be payed
P=principal loan amount
r=annual interest rate
n=number of compounding periods in a year
t=number of years
In our case;
P=$40,000
r=4.7%=4.7/100=0.047
n=12
t=15 years
replacing;
A=40,000(1+0.047/12)^(12×15)-40,000
A=40,000(1.00392)^180-40,000
A=40,842.46821
The amount rounded of to the nearest cents=1/100=0.01, round off to the nearest 2 decimal places=40,842.47
The total amount of interest Samantha will pay=$40,842.47
