Answer:

a4 = 128

a5 = -512

a1= -2

q= (-1)^(n+1) × 4

a5 = a1q⁴ = (-2) (-4)⁴ = -2 × 256 = -512

Use the information to answer the following question.
trasher [3.6K]

Answer:

D is the answer

Step-by-step explanation:

For a: g(x) = 1 when x = 1, for f(x) 1^2 - 2(1) + 2 = 1, a is true.

For b: Both functions do have all real numbers for their domain, b is true

For c: the y-intercept of g(x) is x = 0, for f(x), it is 0^2 - 2(0) + 2 = 2, c is true

For d: g(3) = 7, f(3) = 3^2 - 2(3) + 2  = 5, d is false.

What expression is equivalent to
Vladimir [108]
One way to approach this would be to express 125^2 as (125)(125).

Note also that 125^(4^3) = 125^(1 + 1/3) = (125)(5)

Therefore, the given expression boils down to   

(125)(125)       125
--------------- = ------- = 25
   5 (125)             5

There are other ways in which you could reduce the given expression.
