Hello,
Height: y
Number of branches: B=y-3
Number of leaves on one branche:n=10B²-B
Number of leaves on the tree:
nb=n*B=(10B²-B)*B=10B^3-B²
=10(y-3)^3-(y-3)²=(y-3)²[10(y-3)-1]=(y-3)²(10y-31)
a) if y=9 then nb=(9-3)²*(10*9-31)=36*59=2124.

Answer:
x = 11
Step-by-step explanation:
4x + 7 = 3 (2x - 5)

Answer and Step-by-step explanation:
It be more than 2 ounces and less than 1.5 ounces
The amount of plastic that is melted in 5.7 minutes is 1.71
To find this, you would use the point on the graph. Divide both of those numbers by 4.
(4, 1.2)
4/4 = 1.
1.2/4 = 0.3.
So, for every minute, 0.3 of an ounce of plastic is melted.
We then multiply 0.3 by 5.7 to get 1.71.
