When n = 3, which of the expressions below will be greater than 50? Select all that apply. A) (8n2÷9)⋅7 B) 2n2⋅3 –4n C) 4n2–6n+1

True [87]

Answer:

A

Step-by-step explanation:

a)

$(8(3)^{2} / 9) * 7$

8(9) / 9 = 8 x 7 = 56

$2(3)^{2} * 3 - 4(3)$

2(9) * 3 - 12

18 * 3 = 54 - 12 = 42

$4(3)^{2} - 6(3) + 12$

4(9) - 18 + 12

36 - 18 = 18 + 12 = 30

$7(3) + (3 * 8)$

21 + 24 = 45

Given the function f(x) = log3 (x + 1), determine f^−1(2).

zavuch27 [327]

Given: f(x) = log3 (x + 1), look for f^-1 (2)

We are looking for the inverse of a function. The inverse of the function can be obtained by switching the variables and obtaining the values of the new function, before substituting f(2). Using a calculator:

f^-1 (2) = 8

ehidna [41]

4/5x-8=3
move -8 to the other side and add
4/5x=3+8
4/5x=11
move 5x to the other side and multiply
4=5x*11
4=55x
4/55=x
