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
The answer is x equals 2.
Answer:
x=2/3, x=3/2
Step-by-step explanation:
6x^2-13x=-6
6x^2-13x+6=0
6x^2-4x-9x+6=0
2x*(3x-2)-3(3x-2)=0
(3x-2)8(2x-3)=0
3x-2=0
2x-3=0
x=2/3
x=3/2
