Answer:
(a) 
(b) 
(c) 
Step-by-step explanation:
We have given velocity as function of t 
Acceleration is equation rate if change of velocity with respect to time
So 
(a) Acceleration at t = 5 sec

(b) Acceleration at t = 10 sec

(c) Acceleration at t = 20 sec

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
Answer:
7 weeks
Step-by-step explanation:
Week 1 A - 8 M - 2
Week 2 A - 9 M - 4
Week 3 A - 10 M - 6
Week 4 A - 11 M - 8
Week 5 A - 12 M - 10
Week 6 A - 13 M - 12
Week 7 A - 14 M - 14
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
