Answer:
h(-67) = 3158
Step-by-step explanation:
Simply plug in -67 for <em>x</em>:
h(-67) = -49(-67) - 125
h(-67) = 3283 - 125
h(-67) = 3158
Answer:
The length and width are 11ft and 5ft respectively
Step-by-step explanation:
let the
length = L
Width = W
Area = LW = 55
The length is nine feet less than four times the width
L = 4W - 9
W (4W - 9) = 55
4W^2 - 9W -55 = 0
4W^2 - 20W + 11W - 55 = 0
4W(W - 5) + 11(W - 5) = 0
(W - 5)(4W + 11) = 0
W - 5 = 0 , 4W + 11=0
W = 5 or - 11/4
since the width cannot be negative, W = 5
LW = 55
L = 55/5
L = 11
The length and width are 11ft and 5ft respectively.
Answer:
Step-by-step explanation:
Neither.
It is a complex number. The - sign is the culprit. sqrt(-144) = i * sqrt(144) = 12 i
The "i" is an imaginary representation for the square root of -1. It is a definition for sqrt(-1). So a new category of number has been created. The ancients would have been profoundly surprised to learn that such a thing existed.
