Yes, 5/7 is rational sense it is a fraction where both it's numerator and denominator are integers.

No, 5/7 is a non rational number. If you divided by 5 by 7 u would get a non repeating and non terminating number and for a number to be rational it has to terminate or repeat.

Piecewise functions have different definitions, depending on when you evaluate them.

Given an input x, your function returns:

  • 2x if the input is negative
  • 1 if the input lies between 0 (included) and 2 (excluded)
  • the square root of x if the input is greater than 2 (included)

You want to know what f(0) is. In other words, you want to know what happens if we give 0 as input.

The piecewise definition tells us that, if the input is 0, the function outputs 1.

So, you have f(0) = 1.

Please help with number 5?
Flauer [41]
Unsure how your teacher wants the table to be filled out, but the solution is about 1.62.

x = 1.75, f(x) =1.0625, g(x) =.75 \\  \\ 
x = 1.64, f(x) =.6896, g(x) =.64 \\  \\ 
x = 1.63, f(x) =.6569, g(x) =.63 \\  \\ 
x = 1.62, f(x) =.6244, g(x) = .62 \\  \\ 
x = 1.61, f(x) = .5921, g(x) = .61

Write the first five terms of the sequence in which the nth term is a_n=(n+1)!/n+1.
VikaD [51]

Answer:a) 1,2,6,24,120

Step-by-step explanation:

The formula for the nth term of the sequence is expressed as

n=(n+1)!/n+1

For the first term, n = 1. Therefore,

(1+1)!/(1+1) = 2!/2 = (2×1)/2 = 1

For the second tern, n = 2. Therefore,

(2+1)!/2+1 = 3! /3 = (3×2×1)/3 = 6/3 = 2

For the third term, n = 3, therefore

(3+1)!/3+1 = 4!/4 =(4×3×2×1)/4 = 6

For the fourth term, n = 4. Therefore

(4+1)!/4+1 = 5!/5 = (5×4×3×2×1)/5 = 24

For the fifth term, n = 5. Therefore

(5+1)!/5+1 = 6!/6 = 6× 5×4×3×2×1)/6 = 120
