Answer:

Answer written below.

Step-by-step explanation:

1.

In the statement "r(x-axis) o T(2,-3)", the "r(x-axis)" is a rotation about the x-axis and "T(2,-3)" is a translation by 2 units in the x-direction and -3 units in the y-direction. The order of operations is first translate the object by (2, -3) units and then rotate the object around x-axis.

2.

In the statement "T(-2,5) o R 90° CCW", the "T(-2,5)" is a translation by -2 units in the x-direction and 5 units in the y-direction, and the "R 90° CCW" is a counterclockwise rotation of 90 degrees. The order of operation is first rotate the object 90° CCW and then translate it by (-2,5) units.

3.

In the statement "T(1,4) o r(y-axis)", the "T(1,4)" is a translation by 1 unit in the x-direction and 4 units in the y-direction, and the "r(y-axis)" is a rotation about the y-axis. The order of operation is first translate the object by (1,4) units and then rotate the object around y-axis.

4.

In the statement "r(y-axis) o T(1,4)", the "r(y-axis)" is a rotation about the y-axis, and the "T(1,4)" is a translation by 1 unit in the x-direction and 4 units in the y-direction. The order of operation is first rotate the object around y-axis and then translate the object by (1,4) units.

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

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.
