Answer:
x=8, y=4
Look up the 30-60-90 triangle rule
The force created by the object is 3.75 Newton.
Given
Mass of the object (m) = 1250 grams
Convert 1250 grams to kilograms by dividing it by 1000.
Mass (m) = 1.25 kg
Acceleration of the body (a) = 3 
From Newton's second law we know 
By Substituting in the above equation we get
Force = 1.25 x 3
Force = 3.75 
It can also be written as force = 3.75 N
Hence Force created by the body is 3.75 Newton.

To write this expression as a positive exponent we use this rule of exponents: x^color(red)(a) = 1/x^color(red)(-a) 5^-3 = 1/5^(- -3) .
You add them and then divide by how many numbers there are.
a. (3+43)/2 = 23
b. 0
c. -1
