Answer: There are two formulas that we will use the first one is the y=m x+b and the second one is finding the perpendicular line.
Step-by-step explanation:
the first one is
y=m x+b
y= 3 x -12
the second one is
first find the negative reciprocal of the slope of the original line and use the point slope formula y- y,= m(x - x1) to find the line perpendicular to
Y= 3 x 1
X= 5
Based on the information, there were initially 1200 ferns; the monthly percent rate of change is 68% and this situation is modeled by an exponential growth function
<h3>How to complete the information?</h3>
The given parameters from the question are:
P(n) = 1200(1.68)^n
Where
n represent the number of months
An exponential growth function is represented as:
P(n) = a * (1 + r)^n
Where
a represents the initial value
r represents the rate
By comparison, we have
a = 1200
1 + r = 1.68
This gives
r = 0.68 = 68%
Hence, there were initially 1200 ferns; the monthly percent rate of change is 68% and this situation is modeled by an exponential growth function

Answer:
About $735.03
Step-by-step explanation:
The compound interest formula is A=P(1+r/n)^nt
P is the original amount (principal)
r is the rate
n is the number of times compounded (1 for this one since it is annual)
and t is the time compounded
Answer:36 times for 8 dollars
Step-by-step explanation:
k so first you divide 54 and 12 =4.5 per dollar so you then multiply 4.5 and 8 to get the answer that =36 times for 8 dollars
Answer:
The area of the figure is 143 sq in
Step-by-step explanation:
10 in * 7 in = 70 sq in
12 in * 4 in = 48 sq in
5 in * 5 in = 25 sq in
A = 70 sq in + 48 sq in + 25 sq in
A = 143 sq in
