Answer:
(a) x=-3.15cm
(b)y=0cm
Step-by-step explanation:
Locate the point (4.2,4.9) cm and draw the vector 4.5i+3.j with the origin at this point, the end of the vector is going to be in the point (8.7,7.9). With point (2.2,0), after searching, draw a line to the right to represent that the direction of the field is toward the positive x-axis.
Draw a line in each point in the opposite direction of the field in that point, the point where these lines intersect each other is the position of the particle.
Is the point (-3.15,0)cm
(a) x=-3.15cm
(b)y=0cm
41*2=82 because if you do 82 divided by 2 it is 14

Answer:
about 19.92 meters
Step-by-step explanation:
The circumference is ...
C = πd
72 m = πd . . . . . for outer diameter d
d = (72 m)/π
The inner diameter is 3 meters shorter, so is ...
inner diameter = (72/π) m - 3 m ≈ 19.92 m

Hope this helps!
If you use fractions, the answer you get will always be an exact answer in the form of a fraction. resorting to decimals means that you may run into rounding errors and therefore get only an approximate answer. e.g. the fraction 1/3 cannot be exactly represented by a decimal.fractions can be easier to represent the number rather then using decimals which involve writing out many numbers it does not affect the accuracy of the answer UNLESS you are rounding up and down the numbers
