Try doing the rest. I'll start the problems. All you have to do is solve. Don't forget to label!
41. 25 x 25 ÷ 3
42. (20 x 21 ÷ 3) + (15 x 21)
43. (120 x 60) + (80 x 140 ÷ 3)
I used and got 1.1258999e+15 lol Im sorry Im only in middle school
A scale factor allows a shape to be changes into another shape by changing the linear dimensions to the multiples of the initial dimension and a constant
The expression that finds the change in scale factor for the longer pool with a final length of 33 ft. Sierra is building is the option;
Reason:
Known parameters are;
Dimensions of the pool created = 14 ft. wide × 22 ft. long
Final length of the pool = 33 ft.
Let <em>x</em> represent the length of the drawing using the initial scale factor, we have;
The scale factor of the drawing following a final length of 33 ft. is therefore;
The change in scale factor is given as follows;
Therefore;

Our function is
.
We want to find f(5).
Let's substitute 5 for n.
f(5) = -2f(5-1) + 1
f(5) = -2f(4) + 1
We need to know f(4).
f(4) = -2f(4-1) + 1
f(4) = -2f(3) + 1
We need to know f(3).
f(3) = -2f(3-1) + 1
f(3) = -2f(2) + 1
We need to know f(2).
f(2) = -2f(2-1) + 1
f(2) = -2f(1) + 1
We know that f(1) = 3
f(2) = -2(3) + 1
f(2) = -6 + 1
f(2) = -5
Now we can use f(2) = -5 to find f(3)...
f(3) = -2(-5) + 1
f(3) = 10 + 1
f(3) = 11
Now we can use f(3) = 11 to find f(4)...
f(4) = -2(11) + 1
f(4) = -22 + 1
f(4) = -21
Now we can use f(4) = -21 t find f(5)!
f(5) = -2(-21) + 1
f(5) = 42 + 1
f(5) = 43
