A negative multiplied by another negative equals a positive!
-5+2
-5+2=-3
Answer:
Step-by-step explanation:
<em>The lines form legs of a right triangle, so the distance between the cars is the hypotenuse</em>
<u>The lines at t hours are:</u>
<u>So the distance d is:</u>
- d = √(70t)²+(45t)² = √4900t²+2025t² = √6925t² = 83.22t
- d = 83.22t

Answer:
A ∩ Bc
Step-by-step explanation:
Home constructed of brick:
Event A
Home is less than or equal to 30 years old.
Event B is: {The home is more than 30 years old}
So the event home is less than or equal to 30 years old is the negation(complement) of B. So Bc.
And:
And means intersection.
We have the intersection of events A and the complement of event B, which is represented by:
A ∩ Bc
