Answer:
C. Cardinality of set E is equal to that of O
Step-by-step explanation:
We are given that two sets
a set E of non negative even numbers
E={0,2,4,....}
A set O of non negative odd numbers
O={1,3,5,.....}
We have to choose correct option in given options
We know that
Set of non negative even numbers is countably infinite and set of non negative odd numbers is also countably infinite.
Cardinality of countably infinite set=Aleph naught=![\chi_0](https://tex.z-dn.net/?f=%5Cchi_0)
Therefore, cardinality of E=![\chi_0](https://tex.z-dn.net/?f=%5Cchi_0)
Cardinality of O=![\chi_0](https://tex.z-dn.net/?f=%5Cchi_0)
Therefore, the cardinality of set E is equal to cardinality of set O.
Hence, option C is true.
#First u find the gradient first, remember that the formula of equation of the line is y=mx + c
y = 3x - 3
so the gradient (m) is 3
#Now u find the equation of the line
y - y1 = m(x - x1)
y - 4 = 3(x - 6)
y - 4 = 3x - 18
y = 3x - 18 + 4
y = 3x - 14
<h2>
Answer : y = 3x - 14</h2>
Answer:
They will sound together at 2pm
Step-by-step explanation:
Now, the first thing we need to calculate is , in how many minutes will the two gongs strike together.
To be able to do this, we need to calculate the least common multiple of the two numbers 24 and 40
The lowest common multiple between both is 120
This means that the two gongs will sound together at exactly 120 minutes
Now since 1 hour is 60 minutes, this means that 120 minutes will be = 120/60 = 2 hours
Since they both sounded together at 12 noon and the next time they will be sounding is next two hours, their sounding time will thus be 12 noon + 2 hours = 2 pm
Answer:
Impossible
Step-by-step explanation:
Solve the answer 2-5*28 = -138
This would have no answer since an exponential expression can't equal an negative unless it's a negative answer, but in this case, there is no answer that would get you -138.
Answer:
x-5
Step-by-step explanation:
So glad I could help! Here's why well we do definitely need to factor the area.
Because when factoring we have to expressions multiplying by each other.
A=LxW
Factored Expression=(x+5)(x-5)
See now it's LxW.
IF that makes sense and helped you please hit Thank button!
