A. False. The domain (x-coordinates) starts at 0, not at 100.
b. True. The range (y-coordinates) does start at 100 and increases.
c. True. The graph moves up to the right showing an increase in y as x increases.
d. True. Point (40, 222.11) means that when x = 40 years, y = $222.11.
e. False. The initial point is at x = 0 when the account was opened. At x = 1, it is already 1 year after the account was opened.
Let s represent the short side of the triangle. The long sides of the triangle are each s+1, and the triangle's perimeter is
... s + (s+1) + (s+1) = 3s+2
The length of one side of the square is s-2, and its perimeter is 4 times that, 4(s-2) = 4s-8. The square and triangle have the same perimeter, so
... 3s+2 = 4s-8
... 10 = s . . . . . . . . add 8-3s to both sides
The length of the shorter side of the triange is 10 units.
Perimeter = (2 lengths) + (2 widths) or 2(length + width).
2 (22 + 68.8) = 2 (90.8) = <u>181.6</u>
Percent is pars out of 100
40%=40/100=4/10=0.4
'of' means multiply
0.4 times something=56
divide both sides by 0.4
something=140
th enumber is 140
