Rate of change= (y2-y1)/(x2-x1)=(306-360)/(16-10)= - 54/6= - 9
Yeah I might, show me what you've got.
Y=3(t+2), x=4t
By the Pythagorean Theorem
d^2=x^2+y^2 and using y and x from the beginning and 8^2 for d^2:
64=16t^2+(3t+6)^2
64=16t^2+9t^2+36t+36
64=25t^2+36t+36
25t^2+35t-28=0 I'll just use the quadratic equation as this has no nice integer solutions :)
t=(-35±√(4025))/50 and since t>0
t≈0.5689 hr (34:07 in minutes and seconds :P )
This is the time elapsed for Zach
The answer to the problem is 17
Answer:
0
Step-by-step explanation:
dt/dt=-2t/y
fill in the values:
d(0)/d(0) = -2(0)/-6
0=0/-6
0=0
