Answer:
B
Step-by-step explanation:
The exponential function has the form where a is the starting value or y-intercept. B is the rate of change and x is the variable typically time. In this situation, has starting value 4, rate 3 and a -x.
Normally an exponential curve glides left to right growing steeper as it goes. But a -x flips this behavior. The curve starts very steep then gradually slows down. This means only graphs B or D are options. Since only graph B of these two has a y-intercept at 4, graph B is the solution.
It was difficult to see the grid lines but i believe it is a reflection across the y-axis and a translation of (2,-7). Ry-axis T(2,-7)
Answer:
A. 9
Step-by-step explanation:
A counterexample shows that one side is true while the other is false
x>7 and x>11
sub in the answers
9>7 and 9>11 -this is true for the first half but false for the second
5>7 and 5>11 -this is false for both
13>7 and 13>11 -this is true for both
15>7 and 15>11 -this is true for both
Answer A is correct as it proves the statement to be incorrect
This fair seems like 3 autonomous occasions to me. At the end of the day, you do the adjustment and, on the off chance that it doesn't meet details, you do it once more. On the off chance that regardless it doesn't meet details, you do it a third time. At that point you quit, I figure, and attempt to make sense of why you can't get the darn thing right.
In this way, in any case, you have a .6 possibility of getting the alignment right and a .4 chance you have to rehash it. The solution to your question is the likelihood you don't have three sequential disappointments, which is beneath:
1 - .4 x .4 x .4 = 1 - .064, or 93.6%
