Answer:
y = 0.2·0.5^x
Step-by-step explanation:
An exponential function is generally of the form ...
y = a·b^x
where 'a' is the function value when x=0, and b is the ratio between values for x=1 and x=0.
In the given table, y = 0.2 for x = 0, so a = 0.2.
We find that the value for x = 1 is 0.1, so the value of b is ...
b = 0.1/0.2 = 0.5
Then the exponential function is ...
y = 0.2·0.5^x
We already know that the area of the rectangle increased by a square of the factor 7. So the dilated area of it (which we will call "Ad"), is:
Ad= (47)(7^2)
Ad= 47x49
Ad= 2303 m^2
What is the area of the dilated rectangle? The area of the dilated rectangle is 2303 m^2.

➷ Use this formula:
Area of circle = 
However, as we are using 3.14 for 'pi', we can write it like this:
Area = 
'r' is the radius which is 12ft
Substitute this value into the equation:
Area = 
Solve:
Area = 452.16
Multiply this value by 0.75 to get the answer:
452.16 x 0.75 = 339.12
339.12 square feet is being watered

bearing in mind B is at (4,3) and D is at (-2,-4).
Well if the straight line is equal to 1 then your answer is 2/3 but if the straight line is not equal to 1 you need to know what it is equal to or you could use the equation y = (2/3)x
"x" would be the length of the straight line and "y" would be two-thirds of it
