48 miles per hour! Just double 30 minutes to get an hour, and double 24 as well which equals 48.
Answer: 4-6x^2
Step-by-step explanation:
f•g = f(g(x))
f(g(x)) = 4-2(3x^2) = 4-6x^2
X = k and y = 0 is the solution
Answer: B
Step-by-step explanation:
Answer:
(a) 34.
(b) Yes.
Step-by-step explanation:
The first term is 3(1)^2 + 1 = 4 ( where k = 1).
The sum of 2 terms = 3(2)^2 + 2 = 14.
The sum of 3 terms = 3(3)^2 + 3 = 30.
The sum of 4 terms = 3(4)^2 + 4 = 52.
So the first 4 terms are 4, 10, 16 and 22 . - increasing by 6.
The common difference is 6 so it is an arithmetic sequence.
The 6th term = a1 + d(n - 1)
= 4 + 6(6-1)
= 34.
