Answer:
A
Step-by-step explanation:
Because the x-coordinate is in seconds. Which eliminates answer B
Also, the Y-coordinate is measured in 40 meters per unit, this eliminates C and D.
Which sequence matches the recursive formula? an=2an-1+5, where a1=5. A) 5,10,15,20 B) 5,15,35,75. C)5,15,25,35. D) 5,20,35,40

The recursive formula
means that, to compute the next value, you have to double the previous one and then add 5.
So, we start with 5. To get the second term, we double it and add five, so we have
Next, we will double 15 and add 5:
So, the answer is B, because it's the only option starting with 5,15,35.
Just to check, let's compute the last step:
Which confirms option B
Answer:
5
Step-by-step explanation:
Idc
For this case we have the following function:
f (x) = root (x)
We have the following information:
Reflections
To graph y = -f (x), reflect the graph of y = f (x) on the x-axis. (Vertical reflection)
f (x) = - root (x)
Vertical translations
Suppose that k> 0
To graph y = f (x) + k, move the graph of k units up.
f (x) = - root (x) +3
Answer:
f (x) = - root (x) +3
option C
