That means when x=0
e^-0.2x =e^0=1
So f(0)=15/5=3
Answer:



Step-by-step explanation:
3) Area of a circle is

Where r = 6
Thus,




4) False
Area of a circle is measured by the formula below:

5) The formula for calculating the area of a rectangle is given thus:

Where, l = 10ft; w = 7ft

Answer:
The answer is 3.
Step-by-step explanation:
Given that the Indices Law is,


So the expression is :





Y = -5x + 9
y = 5x + 7
5x + 7 = -5x + 9
5x + 5x = 9 - 7
10x = 2
x = 2/10 reduces to 1/5
y = 5x + 7
y = 5(1/5) + 7
y = 1 + 7
y = 8
solution is (1/5,8)
20/35 gallons per hour
(20/35) * 47 = around 27 gallons in 47 hours
