Answer:
at 2/3 seconds
Step-by-step explanation:
S1(t) = t³ + 2
Average speed, dS1/dt = 3t²
S2(t) = t²
Average speed, dS2/dt = 2t
The distance between the objects is
dS1/dt - dS2/dt
= 3t² - 2t
The time the distance between the two object is at minimum is when the distance is 0
That is, when
3t² - 2t = 0
t(3t - 2) = 0
t = 0 or 3t - 2 = 0
t = 0 or t = 2/3
Answer:
You must be trolling. 48 degrees
Step-by-step explanation:
48 plus 42 = 90
285.
60 x 4 = 240.
add 45 = 285.
Move the decimal to the right 11 times. 2,456,00,000,000
Multiple coordinates work. If you turn this equation into y=mx+b form it is easier. That would be y=-7x+9. A couple coordinates that work are (0,9) (1,2) and (2, -5)
