Answer:
x^-2
Step-by-step explanation:
(x*x*x)/(x*x*x*x*x)
1/x*x
1/x^2
x^-2
Second moment of area about an axis along any diameter in the plane of the cross section (i.e. x-x, y-y) is each equal to (1/4)pi r^4.
The second moment of area about the zz-axis (along the axis of the cylinder) is the sum of the two, namely (1/2)pi r^4.
The derivation is by integration of the following:
int int y^2 dA
over the area of the cross section, and can be found in any book on mechanics of materials.
Answer:
The point slope form of that graph would be D) y + 7 = 2/5(x + 4)
Step-by-step explanation:
We know this by plugging into the point-slope form of the equation, which is listed below.
y - y1 = m(x - x1)
y - -7 = 2/5(x - -4)
y + 7 = 2/5(x + 4)
Answer: Maggie is 7 years old.
Step-by-step explanation:
Maggie = x years old
Maggie’s brother = 4x - 3 years old
x + 4x - 3 = 32
5x -3 = 32
5x = 35
x = 7
93.2
= 93 + 0.2
= 93 + 2 /10
= 93 and 2/10
= 93 and 1/5
As mixed fraction = 93 and 2/10 or 93 and 1/5
