Step-by-step explanation:
The Answer is
D) The rate of change for function B is greater than the rate of change for function A.
Answer:
x = -7/2 or x =1
Step-by-step explanation:
2xx - 5x - 7 = 0
2x(x - 1) + 7(x - 1) = 0
(2x +7) (x -1) = 0
x = -7/2 or x =1
18 choose 7
=C(18,7)
=18!/(7!(18-7)!)
=31824
OR
18 choices for first passenger,
17 choices for second passenger,
....
12 choices for 7th passenger,
so total = 18*17*16...12
but there are 7! ways to order the 7 passengers, so
number of groups
=18*17*16...12/7!
=31824 as well
Answer:the answer is 3120
Just by comparing the plots of f(x) and g(x), it's clear that g(x) is just some positive scalar multiple of f(x), so that for some constant k, we have
g(x) = k • f(x) = kx² = (√k x)²
The plot of the transformed function g(x) = (√k x)² passes through the point (1, 4), which means
g(1) = (√k • 1)² = 4
and it follows that k = 4. So g(x) = 4x² = (2x)² and B is the correct choice.
