Answer:
1071.8 to 1 decimal point
Step-by-step explanation:
The first thing you would do is multiply the 4/3, 3.14 and the 8^3
So we know that 8^3 is 8X8X8 which is 512
So the first thing you do I 4/3 X 3.14 X 512 = 160768/75 (2143.6 1DP)
Then you would divide this by 2
2143.6/2 = 1071.8
Step 1: learn to draw a free-body diagram. Read your school notes or look up a web site on the subject.
Step 2: Denote the angle of the ramp with the horizontal as theta=tan^(-1)(20/30)=33.69 degrees (approx.)
Step 3: denote the mass of the object as m=100 lb-mass.
Step 4: find force due to mass and gravity = -100g = -100 lb-force. (downwards), denoted by the vector F=(0,-100) lb-force.
Step 5: resolve force along incline:
Force parallel to incline = F1 = -100(cos(theta))
=-83.21 lb-force (negative => down the incline)
Step 6: resolve force perpendicular to incline
= F2 = -100(sin(theta)
=-55.47 lb-f (-ve =>into the incline)
By the way, this question is not calculus 3, but more mechanics, or physics. You have a better chance of getting answers if posted under "physics".
Answer:
x=0
I used phone math!!!!!!!!
In the complex plane, this polynomial has three roots, exactly as its degree is.
Hope this helps.
