Answer:
(0, 2) and (1, 1)
Step-by-step explanation:
When x=0, the exponential term is 1, so the value of the function is the multiplier, 2. Thus (0, 2) is a point on the graph.
When x=1, the value of y is half of 2, so (1, 1) is also on the graph.
__
For x > 1, y < 1, so (2, 2.25) cannot be on the graph.
f(x) cannot be negative, so (-2, -8) and (-1, -1) cannot be on the graph.
Answer:
width 5
length 7
Step-by-step explanation:
W * L = 35
L = 4 * W - 13
W * (4W-13) = 35
4 W^2 - 13 W - 35 = 0
delta = 169 + 4*4*35 = 729 = 27^2
W = (13 + 27) / 8 = 5 (its the only solution since 13 - 27 is less than 0 which makes no sense)
L = 4 * 5 - 13 = 7
Answer:
1 2/3
Step-by-step explanation:
I will answer the second question :
40---> 14
50----> x
x= (14*50) / 40
x= 17.5
Answer:
495.
Step-by-step explanation:
The number of arrangements of letters = 12! / 8!4! because there are a total of 1 letters and 4 are a's and 8 are b's.
