The long piece of the board is 100 cm and the shorter board is 20. you can solve this by dividing 120 by 6 since u need to have a piece that is 5x a piece which is a total of 6 pieces. Then multiply that number by 5 and that is your longest board.
Answer:
The coordinates of the end point B are (14 , 8)
Step-by-step explanation:
let B(x , y)
M midpoint of A and B
⇔ 8=(x+2)/2 and 11=(y+14)/2
⇔ 16=x+2 and 22=y+14
⇔ x=14 and y=8
Answer:
Step-by-step explanation:
what are the equations?
39. 7 times 5 equals 35 plus 4 equals 39 :)
Answer:
Tn = -n^2 - n + 21 is the formula for the nth term.
Step-by-step explanation:
The second differences are all equal in this quadratic sequence.
Now, the quadratic sequence has a formula of Tn = an^2 + bn + c
Find the value of a in an^2 by dividing the difference by 2:
-2/2 = -1
a = -1
Since T1 is 19 and T2 is 15 we can put that into the equation and simplify:
b + c = 20
2b + c = 19
Thus, b = -1 , c = 19 and the general formula for the nth term is Tn = -n^2 - n + 21
