Answer:
176 mph after 8 seconds
Step-by-step explanation:
This is an arithmetic sequence with common difference 22 mph and first term 22. Thus, the nth term is a(n) = 22 + 22(n - 1).
Thus, the 8th term is a(8) = 22 + 22(7) = 176 mph
Answer:
C=37.680
Step-by-step explanation:
The diameter is 2x the radius, so 6x2 is 12. 12x3.14 = 37.680.
Answer:
c=d(3.14)
c=25.12
Step-by-step explanation:
Answer:
(x + 6)(x - 2)
Step-by-step explanation:
To factor the quadratic
Consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term ( + 4)
The factors are + 6 and - 2 since
+ 6 × - 2 = - 12 and + 6 - 2 = + 4, hence
x² + 4x - 12 = (x + 6)(x - 2)
