Answer:
all are answers except P(x) = 7x^2 +11x - 6 and P(x) = x^3+ x^2 + x
Step-by-step explanation:
All answers with a negative slope in the highest order polynomial will approach negative infinity as x approaches infinity. This means that all are answers except P(x) = 7x^2 +11x - 6 and P(x) = x^3+ x^2 + x
Answer: (-5, 2). Please mark me brainliest
Step-by-step explanation: So we are finding the coordinates of point A first we have to mark the x-coordinate (-5) so we have to look at the horizontal line (x-coordinate) and the A is an -5 so the first part should be -5 next we have to do the vertical line (y-coordinate) and it is on the 2 so 2 so the answer is (-5,2).

Answer:
<em>The Boeing 747 had an average speed of 580 mph.</em>
Step-by-step explanation:
<u>Constant speed motion</u>
An object is said to travel at constant speed if the ratio of the distance traveled by the time taken is constant.
Expressed in a simple equation, we have:

Where
v = Speed of the object
d = Distance traveled
t = Time taken to travel d.
From the equation above, we can solve for d:
d = v . t
And we can also solve it for t:

The small airplane travels 1015 miles at a constant speed of v=290 miles/hour. The time it took to arrive its destiny was:

t = 3.5 hours
The Boeing 747 left from the same point 1.75 hours after the small plane and traveled the same distance. It needed a time t' = 3.5 - 1.75 = 1.75 hours, thus its speed must have been:

The Boeing 747 had an average speed of 580 mph.
