y = -4(x +2)² + 7

formula for parabola: y = a(x-h)² + k

Where (h, k) denotes the vertex

vertex: (-2, 7) point: (-1, 3)

First find a:

3 = a(-1-(-2))² + 7a + 7 = 3a = -4

Thus equation:

y = -4(x-(-2))² + 7y = -4(x +2)² + 7

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
