Answer:
No
Step-by-step explanation:
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
Answer:
option B
Step-by-step explanation:
the slope is -2, so the equation must have -2x in it.
This narrows it down to option C and B
the intercept is at -5, not +5 so the correct answer is y = -2x - 5
Answer:
Step-by-step explanation:
The formula for compounding continuously is
We have that A(t) = 9600, r = .011, and t = 3
Filling in and solving for P:
and
and
so
P = 9288.37
