Answer:
Part a) The area of the actual fish pond is 
Part b) The length of the fence will be 
Step-by-step explanation:
we know that
The scale drawing is

step 1
Find the actual dimensions of the fish pond
To find the actual dimensions divide the measure of the drawing by the scale drawing
step 2
Find the area of the actual fish pond
The area of the fish pond is equal to the area of a circle p[lus the area of rectangle

we have



substitute

step 3
Find the length of the fence around the entire fish pond
The perimeter of the fish pond is equal to the circumference of a complete circle plus the length of 75 ft two times
so

we have

substitute

Answer:
x = 10
y = 9
Step-by-step explanation:
First, you need to write two equations that represent the information given. I'm going to set the two numbers and x and y.
x - y = 1
x + y = 19
This turns it into a systems of equations. When you add the two equations, keeping everything on each side, you eliminate a variable, and solve for the other.
2x = 20
x = 10
Now, you'd plug x into either original equation.
(10) - y = 1
-y = -9
x = 10
I hope this helped!
First differences are ... 0-7 = -7, -1-0 = -1, 4-(-1) = 5, 15-4 = 11, 32-15 = 17.
Second differences are -1-(-7) = 6, 5-(-1) = 6, 11-5 = 6, 17-11 = 6.
The second differences are constant at 6, so the table values would be best fit by a function that is ...
_____
The degree of the polynomial function corresponds to the level of differences that are constant (when the x-values are evenly spaced).
The quadratic function that matches these values is
... y = 3x² +2x -1
... y = (3x-1)(x+1) . . . . in factored form
