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) $0.134m/sec^2$

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

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

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

Which ordered pairs to the equation 5x+12y=15 (5,-5/6) (-3,5/2) ( -6,15/4) (-5,10/3)

Ksju [112]

Answer:

All of them

Step-by-step explanation:

All we have to do is replace the x and y with their following coordinates

A.(5, -5/6) - - > 5(5) + 12(-5/6) = 25 + (-10) = 15

15 = 15

Yes

B. ( -3, 5/2) - - > 5(-3) + 12(5/2) = -15 + 30 = 15

15 = 15

Yes

C. (-6, 15/4) - - > 5(-6) + 12(15/4) = -30 + 45 = 15

15 = 15

Yes

D. (-5, 10/3) - - > 5(-5) + 12(10/3) = -25 + 40 = 15

15 = 15

Yes

Please anyone<br> its done today<br> 2m2+ 2m − 12 = 0

MrMuchimi

is it factorisatiom or solving equation?

Step-by-step explanation:

2m² + 2m - 12 divide the equation by 2

then: m² + m - 6

factorise: (m + 3)(m - 2)

solve m + 3 =0 or m - 2 =0

m= -3 or m = 2
