Answer:
12
Step-by-step explanation:
12
This sequence has generating function
(if we include for a moment)
Recall that for , we have
Take the derivative to get
Take the derivative again:
Take the derivative one more time:
so we have
Answer:
3, and b
Step-by-step explanation:
1. x =3
Because you have 3 little squares for one x
2. x= -12
b) 15+6=21
Answer:
21
Step-by-step explanation:
if v=2
then uw=21
because 6/2=3, and
14/2=7
3x7=21
Answer:
A) gallons
B) Distance between Town A and Town B is miles
Step-by-step explanation:
A)
We know, number of gallons =
if miles per gallon (mpg) is given as 24 & total distance travelled is 3x miles, then, using formula we have:
Number of Gallons =
B)
Now, given is number of gallons = 2y & we know mpg is 24; <em>so what is the distance?</em>
We use the same formula and solve for distance (let distance between A and B be "D"):
