Since the variable x is at the exponent, this is an exponential function.
To decide whether an exponential function is a growing or decaying one, we have to look at the base of the exponent.
If the base is between 0 and 1, we have exponential decay
If the base is larger than 1, we have exponential growth.
In your case the base is 3, which is larger than 1, so you have exponential growth.
Thus, <u>option d</u> is your answer
Answer:
b,c,e
Step-by-step explanation:
Use the permutation formula
nPr = (n!)/((n-r)!)
20P15 = (20!)/((20-15)!)
20P15 = (20!)/(5!)
The final answer is choice A
Is there supposed to be an equation that follows? Can I see the entire question?
Answer:
x=88
Step-by-step explanation:
That third line is a transversal, making 92 and x supplementary to each other.
92+x=180
x=88
