Answer:
For part one 30000 and the slope for part two is -2000 and for part three it is y=30000=2000x.
Step-by-step explanation:
If it starts at 30,000 then that is on the 0 on the x-axis.
While the plane is descending by 2000 so that is the slope but because it is descending and not rising it is -2000. If it was rising it would be 2000.
And for part three because it starts and 30000 and it goes down 2000 by the x-axis.
Hope this helps.
Area of a rectangle of length L and width W is A = LW.
Here, A = 60 ft^2 = (12 ft)(2x-3 ft). Let's find the values of x for which the area =60 ft^2, and then the values of x for which the area is greater than 60 ft^2.
60 = 12(2x-3) becomes 5 = 2x - 3 after dividing both sides by 12.
Adding 3 to both sides of this last equation results in 8 = 2x, so x = 4.
Does (12 ft)(2[4 ft] - 3) = 60? Does (12 ft)(5 ft) = 60 sq ft? YES.
The area of this rectangle will be greater than 60 sq ft if x>4 ft. (answer)
Max’s distance : Dave’s distance = 2 km : 5 km = 2:5
Max’s time : Dave’s time = 40 min : 15 min = 40:15 = 8:3
