Answer: Suppose we have four ants, initially at rest, at the four corners of a square centered at the origin. They start walking clockwise, each ant walking directly toward the one in front of him. Suppose also that each ant walks with unit velocity, derive a differential equation that describes the trajectories.
Answer:
The 8th number is -9
Step-by-step explanation:
With an average, the sum of the seven numbers divided by 7 is 15.
In order to add an 8th number, we set up

Answer:
Step-by-step explanation:
64
because the small triangle at the top is isoscel and has the base angles BDE and BED = (180 -48)/2 =66
angle BDE is congruent to DAC = 66, because 2 || BE and AC are cut by transversal BA
angle ADC = 180 -50 -66 = 64
Answer:
Option: A is correct.
Step-by-step explanation:
Since we are given a information that:
A contractor needs to fence a rectangular backyard for a client.
(1) The length of the backyard should be at least(gretaer than or equal to)
150 ft.
The length of the backyard is denoted by 'y' as in the graph.
Hence according to statement (1) we have:
y≥ 150
(2) The distance around should be no more than 450 ft.
This means that the perimeter has to be less than or equal to 450 ft.
Hence, 2x+2y ≤ 450.
So such inequalitiies on graphing will give the graph same as in A option.
Hence option A is correct
