Answer:
x=-1,y=0
Step-by-step explanation:
-10y+9x=-9
10y+5x=-5
14x=-14
x=-1
-10y-9=-9
y=0
Answer:
-1/2
Step-by-step explanation:
Tell me if you want a step by step.
Hope this helps. :)
With 5 elements in A={20,1,6,10,11}, there are 2^5=32 possible subsets, including
the null set, and A itself.
Any subset that is identical to A is NOT a proper subset.
Therefore there are 31 proper subsets, plus the subset {20,1,6,10,11}.
The subsets are:
null set {} (has no elements) ........total 1
{20},{1},{6},{10},{11}.......................total 5
{20,1},{20,6}...{10,11}.....................total 10
{20,1,6},{20,1,10},...{6,10,11}.........total 10
{20,1,6,10}...{1,6,10,11}.................total 5
{20,1,6,10,11}.................................total 1
Altogether 32 subsets.
By definition,
sin(angle) = opposite/hypotenuse
From the picture,
sin(60°) = VT/PV
√3/2 = VT/35
√3/2*35 = VT
30.3 meters = VT
The first one is A because 8/100times 2 equals 16/200
