What is the 6th term of the geometric sequence 4, −20, 100, ...?
shtirl [24]
Let's calculate r of this G.P: (-20)/(4) = - 5(100)/(-20) = - 5So r = -5
The formula to find the nth term of a GP is;
a(n) = a(r)ⁿ⁻¹
<u />a₆ = a(r)⁶⁻¹
a₆ = 4(-5)⁵ = -12500<u />

The velocity of an automobile starting from rest is given by the equation below, where v is measured in feet per second and t is
podryga [215]

Answer:

(a) 0.408m/sec^2

(b) 0.134m/sec^2

(c) 0.039m/sec^2

Step-by-step explanation:

We have given velocity as function of t v(t)=\frac{85t}{(8t+14)}

Acceleration is equation rate if change of velocity with respect to time

So a=\frac{dv}{dt}=\frac{(8t+14)85-85t\times 8}{(8t+14)^2}

(a) Acceleration at t = 5 sec

a=\frac{(8\times 5+14)85-85\times 5\times 8}{(8\times 5+14)^2}=0.408m/sec^2

(b) Acceleration at t = 10 sec

a=\frac{(8\times 10+14)85-85\times 10\times 8}{(8\times 10+14)^2}=0.134m/sec^2

(c) Acceleration at t = 20 sec

a=\frac{(8\times 20+14)85-85\times 20\times 8}{(8\times 20+14)^2}=0.039m/sec^2
