<span>Find
the speed of each car.
Let a be the first car
Let b be the second car
=> a = x miles per hour
=> b = x + 12 miles per hour
=> 2 (x+ x + 12) = 232 miles per hour
=> 2x + 12 = 232
=> 2x + 12 = 116
=> 2x = 116 - 12
=> 2x / 2 = 104 / 2
=> x = 52 (speed of Car A)
=> 52 + 12 = 64 miles per hour (speed of Car B)</span>
Answer:
A ∩ B = {2, 4}
Step-by-step explanation:
Definition: The intersection A ∩ B of two sets A and B is the set that contains all elements of A that also belong to B.
For example:
If x∈A and x∈B
then;
x∈ A ∩ B
Given the sets:
A = {1, 2, 3, 4, 5} and B = {2, 4}
We have to find A ∩ B.
By definition we have;
A ∩ B = {2, 4}
Therefore, the value of A ∩ B is, {2, 4}
Answer:
Odd function
Step-by-step explanation:
The given function is 
We know that:
- The function is even if f(-x) = f(x)
- The function is odd if f(-x)=-f(x)
- If the function doesn't satisfy these two properties then it is neither odd nor even.
Hence, we substitute x = -x to find f(-x)
Since, f(-x)=-f(x). Hence, the function is odd.
