Answer:
(213.8, 419.3)
Step-by-step explanation:
The center of mass is the point at which the sum of the weights relative to each other is zero. The weight distribution is balanced around the mass, and the average of the mass position coordinates of the scattered weight defines its coordinates. Calculations in mathematics are simplified when formulated according to the center of mass.
For finding the place of the center of the mass we should use the formulas below for X AND Y points:
Segment CM X Position = X proximal + A*(Xdistal - Xproximal)
Segment CM Y Position = Y proximal + A*(Ydistal - Yproximal)
A is the percentage of how much the center of mass is from proximal end.
We have:
Proximal X=213
Proximal Y=400
Distal X=378
Distal Y=445
and the percentage of the distance to proximal end, A=42.9%
Segment Central of mass for X is:
CM X = X proximal + A*(Xdistal - Xproximal)=213+0.429*(378-213)=213.8
CM Y= Y proximal + A*(Ydistal - Yproximal)=400+0.429*(445-400)=419.3
So we found that the point on the space for the center of mass is (213.8, 419.3)
Answer: 803.84 square inches
Step-by-step explanation:
A sphere is a 3 dimensional solid and its surface area is the total number of square units that will cover the sphere's surface.
The formula for the surface area of a sphere is expressed as 4πr^2
Where
r = radius of the sphere
π i s a constant with a value of 3.14
From the information given,
Diameter of the sphere = 16 inches
Radius of sphere = diameter of sphere divided by 2
Radius of sphere = 16/2 = 8 inches.
Surface area of sphere
= 4 × 3.14 × 8^2 = 803.84 inches^2
First solve it
5x-7y = 10 - 5x
-5x
-7y = 10-5x
so divide everywhere by -7 so get the fraction you will get the y-intercept and slope
Answer:
0.1356 g
Step-by-step explanation:
The formula for density is, , so we can plug in our values and solve for m, the mass.
1.2x10⁻²=
m= 0.1356 g
