What I usually do is I take the numbers and flip it so now it's 538-247 which equals 291 but since I had to flip it I put a - sign in front of my answer
so 247-538 is -291
To get the percent of increase, we will simply follow these steps:
1- get the difference between the two numbers:
difference = 1.8 - 1.2 = 0.6 mg
2- divide the difference by the original number and then multiply the quotient by 100 to get the percentage
% of increase = (0.6/1.2) * 100 = 50%
Answer: True
Step-by-step explanation:
We know that the quadratics polynomials have this form:
You need to remember that the degree of a polynomial is given by its highest exponent.
You can observe in the quadratic polynomial that the highest exponent is "2", which is the exponent of the term 
Therefore, since the highest exponent is "2", you should conclude that the degree of the polynomial is 2.
Then, you can say that a quadradic polynomial has degree 2.
Answer:
Step-by-step explanation:
Work is said to be done when a force applied to an object cause the body to move in a specified direction.
Work-done = Force * Distance
Since Force = mass * acceleration due to gravity
Work-done = mass * acceleration due to gravity * distance
Given mass = 1.4kg, distance = 0.7m and g = 9.8m/s²
Workdone in lifting the book off the floor = 1.4*0.7*9.8
Workdone = 9.604Joules
- Similarly, work done in lifting a 21-lb weight book 6 ft off the ground is expressed using the same formula as above;
Given mass = 21-lb, g = 32ft/s² and distance = 6ft
Workdone = 21 * 32 * 6
Workdone = 4,032 lb-ft²/s²
Hence, work-done in lifting a 21-lb weight book 6 ft off the ground is 4,032 lb-ft²/s²
