Just use derivatives:
f'(x)= .48x-.96 = 0, x = 2, since the coeff of x^2 is +, this is a minimum
x=0 1989, so x = 2 is 1991! :)
Answer:
1) I think the answer is A
2) (A), (D) (B) Those numbers are irrational because irrational numbers are all the real numbers which are not rational numbers, the latter being the numbers constructed from ratios of integers. (change some words please)
3) This number is irrational because irrational numbers are all the real numbers that are not rational.
4) 6/25
5) 0.875 since I can't show work, you divide 7 by 8
6) I don't know the answer, so maybe D and B ?
7) point A
8) 8.3 inches
9) I think it is the = I am not sure
10) Irrational because it has no pattern

Answer:
a. 76 b. 52
Step-by-step explanation:
The perimeter of a rectangle is the sum of its four sides.
Now all rectangles have a width and a length.
To find the perimeter it is 2 width + 2 length or 2W +2L.
So if the Perimeter P = 344 and Width W = 76 and P = 2W + 2L
Then...
2(76) + 2L = 344 multiply 2 and 76
2L + 152 = 344 subtract 152 from both sides
2L = 192 divide both sides by 2
L = 96
The length is 96.
The equation of an area of a rectangle is A or area = width x length or W x L
So the equation is A = W x L
If the area is 4732 and the length is 91 then
91W = 4732 divide both sides by 91
W = 52
The width is 52.
Hope that helps, good luck with your homework!
