Answer:
-390 mph
Step-by-step explanation:
Let a and b represent, respectively, the distances of A and B from the airport. The distance d between the planes is then given by the Pythagorean theorem as ...
d² = a² + b²
Differentiating with respect to time, we have ...
2d·d' = 2a·a' +2b·b'
Solving for d', we get ...
d' = (a/d)a' +(b/d)b'
The value of d at the time of interest is ...
d = √(a² +b²) = √(30² +40²) = √2500 = 50
Then the rate of change of separation is ...
d' = (30/50)(-250 mph) +(40/50)(-300 mph) = (-150 -240) mph
d' = -390 mph
The distance between planes is decreasing at 390 miles per hour.
Lets look at the info we have:-
23 orders for Pepsi.
15 orders for mountain dew.
Question:-
How many more orders have there been for Pepsi than for Mountain Dew?
To answer this we will subtract the amount of Pepsi's ordered by the amount of Mountain Dew's ordered. The answer will be the amount of more Pepsi's ordered than the Mountain Dew's.
23 - 15 = 8
8 more Pepsi's were sold than Mountain Dew's.
CHECK OUR WORK:-
15 + 8 = 23
We were RIGHT!!!
So, 8 more Pepsi's were ordered than Mountain Dew's.
Hope I helped ya!1 xD
Yes because you only need to look at the first decimal for problems like these and the first number you see a seven and a one and seven is greater than one
So hmm notice the picture below
you have the center, and a point on the circle... all you need is the radius
then use that radius in the circle's equation
Answer:
line p matches with the first equation
