Let x = the length of a side of the square (m).
The area is
A = x²
The perimeter is
P = 4x
The rate of change of P with respect to x is
P'(x) = 4 (independent of x)
When A = 49 m², then x = 7 m.
The rate of P is 4.
Answer: 4
Answer:
the log function is the "inverse" function of an exponential function
by definition
then 
in this problem you have 
thus what x solves this ?
the answer is 
thus (100,2)
B) the x intercept is when y = 0

x intercept at (1,0)
C) at 100, the curve will hit y = 5000

Answer:
65
Step-by-step explanation:
The problem statement tells you ...
1.20x = 78
Dividing by the coefficient of x gives its value:
x = 78/1.20
x = 65
Answer:
24/3-4
Answer is 12
Step-by-step explanation:
To find the answer, you have to work backwards. You also have to use PEMDAS. Since she multiplied her answer to get 24, you have to work backwards and divide by 3 first. You will get the number 8 after that because 24/3 is 8. Since she also subtracted 4, you have to work backwards and add 4. That gives you an original number of 12.
