Answer:
i) mAB = mBD (Not True)
Step-by-step explanation:
ii) mAC = mAD , CD is a chord and AB is a diameter. CD⊥AB and hence AC = AD,
Equal chords have equal segments . Hence it is true
iii) ∠BDA = ∠BCA true
iv) ∠PBC = ∠DBA True
Hence the three options are correct except the one.
So our answer is option A mAB = mBD (Not True)
5 cans need to be bought. There are three servings in each can so you divide 15 by 3.
Answer:
12ft
Step-by-step explanation:
i think it is right
<span> RdΘ/dt = v </span>
<span>dΘ/dt = (1/3)/20 = 1/60 rad/sec </span>
<span>5(1/60 ) = 5/60 cm/sec = 1/12 cm/sec </span>
<span>Angular Speed = dΘ/dt = 1/60 rad/sec </span>
<span>Linear Speed = RdΘ/dt = 1/12 cm/sec </span>
X= width of the path.
we can suggest this equation:
(20+2x)(28+2x)=1584
we solve this equation:
(20+2x)(28+2x)=1584
560+40x+56x+4x²=1584
4x²+96x-1024=0
4/4x²+96/4x-1024/4=0/4
x²+24x-256=0
We solve this square equation:
x=[-24⁺₋√(576+1024)]/2=(-24⁺₋40)/2
we have two solutions:
x₁=(-24-40)/2=-32 this solution is not valid.
x₂=(-24+40)/2=8
Answer: the width of the path is 8 m.
