In how many hours would they be 800 km apart?
1 answer:
The two cars (a and b) will be 800 km apart after 10 hours.
<h3>What is the average speed of a car?</h3>The average speed of a car is the total distance traveled by a car within a specific period of covering such distance.
From the given information:
- If the speed of car A (v_a) = 30 km/hr; and
- The speed of car B (v_b) = 50 km/hr
The distance between both cars will be the hours they will meet:
i.e.
30t + 50t = 800
80t = 800
t = 800/80 hrs
t = 10 hrs

An equation is used to represent expressions with equal values. The equation to find the value of b is:
Given that:
To get the value of distance b, we simply add up the length of every item that makes up the cross-section.
So, we have:
Collect like terms
Substitute
Convert inches to feet
Collect like terms
Divide both sides by 5
Hence:

<h3>Answer: As 
and as 
</h3>
Basically, whether x goes to positive or negative infinity, the value of y will head off to positive infinity.
Why is this? It's all because of the leading term 75x^4. This is the term with the largest exponent, so the degree is 4. Even degree functions have the endpoints pointing in the same direction. In this case, that direction is up or pointing along the positive y axis direction. If the leading coefficient was negative, then y would head off to negative infinity instead of positive infinity.
