Answer:
Solve the inequality k + 6 ≤ 21;
(A)k ≥ 27
<u>(B)k ≤ 15 </u>
(C)k ≥ 15
(D)k ≤ 27
Step-by-step explanation:
Let the point be P, and the masses be located at P1 and P2.
The centre of mass is such that the moments of masses m1 and m2 exert an equal moment at the point P,
and the distance P1P2=d
namely,
m1(mPP1)=m2(mPP2)
The distance of the centre of mass from m1 is therefore
d1=d*m2/(m1+m2)
Similarly, the distance of the centre of mass from m2 is
d2=d*m1/(m1+m2)
Make a square with each side (square root of 2) times the cicrcle's radius (1/2 the diameter) and the square exactly fits inside the circle.
Answer:
D is incorrect
Step-by-step explanation:
If you know the measure of two angles of a right triangle and you only one length of a right triangle then you will be able to ONLY find the length of the third angle of a right triangle and not the other two sides.
