Answer:
Choice C. 5 miles per hour
Step-by-step explanation:
(1/4)(20) = 5 per hour
Answer:
its the top right answer choice
you'd simply just need to subtract 80 from 210 since its 10 per visit, and after 8 visits well its self explanatory

Answer:
x = 10
Step-by-step explanation:
50 = (6x - 10) rewrite it
50 = 6x - 10
+ 10 + 10 add 10 to both sides
60 = 6x you're left with 60 and 6x
60/6 = 6x/6 divide both sides by 6 to get x by itself
10 = x the answer is whatever you're left with after dividing
Answer:
B. Exponential
Step-by-step explanation:
The annual wolf population in each year is
w = 500 500(0.9) 500(0.9)² 500(0.9)³ …
n = 1 2 3 4 …
The model is w = 500(0.9)ⁿ⁻¹.
This is an exponential model, because the independent variable is in an exponent.
<span>the particle's initial position is at t=0, x = 0 - 0 + 4 = 4m
velocity is rate of change of displacement = dx/dt = d(t^3 - 9t^2 +4)/dt
= 3t^2 - 18t
acceleration is rate of change of velocity = d(3t^2 -18t)/dt
= 6t - 18
</span><span>the particle is stationary when velocity = 0, so 3t^2 - 18t =0
</span>3t*(t - 6) = 0
t = 0 or t = 6s
acceleration = 6t - 18 = 0
t = 3s
at t = 3s, velocity = 3(3^2) -18*3 = -27m/s
displacement = 3^3 - 9*3^2 +4 = -50m
