Answer:
Mass = 1.3 Kilograms.
Step-by-step explanation:
Given the following data;
Force = 55.1 N
Acceleration = 41.6 m/s²
To find the mass of the stone in kg;
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
Force = mass * acceleration
Substituting into the formula, we have;
55.1 = mass * 41.6

Mass = 1.3 Kilograms
The exterior angles of any convex polygon add to 360 degrees. So for a regular pentagon, the exterior angle is 360/5 = 72 degrees. The interior angle is supplementary to the exterior angle so is 180 - 72 = 108 degrees. So the sum of them is 5(108) = 540 degrees.
Answer: 540 degrees
Answer:
140 feet
Step-by-step explanation:
You will need to find the perimeter of the backyard to find how many feet of fencing will be needed
the formula for perimeter is: 2l+2w
So 2 times 30 is 60
with 2 times 40 80
60+80 is 140
Thus you will need 140 feet to cover the backyard
Hope this helps!
Answer:
(x-2)^2+ (y+3)^2 = 64
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2+ (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
(x-2)^2+ (y- -3)^2 = 8^2
(x-2)^2+ (y+3)^2 = 8^2
(x-2)^2+ (y+3)^2 = 64
