10. The table shows the number of diagonals for polygons with n sides. Number of
3 4. 5 6. 7. 8
sides, n
Number of
0 2 5 9 14 20
diagonals, d
Find a polynomial function that fits the data.

Determine the total number of diagonals in the decagon shown.

11. Explain why you cannot always use finite differences to find a model for real-life data sets.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

y=mx+b

step-by-step explanation:

m slope

b y-intercept

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

answer is : muchas/tipicas

have a nice day!
