Because 35 is divisible by 7, but 23-21=2, so it becomes 25, which 7 is not a factor of. therefore, it is not divisible by 7.
When working with functions (of all types), the average rate of change is expressed using function notation:

For the interval from x=7 to x=8,
1. find f(7) and f(8):
2. use given formula:

Answer: the average rate of change for the interval from x=7 to x=8 is 4374.
Answer:
y = sin(x + 90°)
Step-by-step explanation:
cos 0 = 1
Since the point (0, 1) is on the graph, this graph is y = cos x, but that is not a choice, so this must be the graph of the sine function with a horizontal translation.
sin 0 = 0
sin 90° = 1
The translation is 90°.
Answer: y = sin(x + 90°)
I think it’s
20,400*10=204,000
