Question

What is the value of F(x)=2(0.75)^x when x equals 3?A.4.5B.3.375C.1.5D.0.8444What type of situation could be represented by the function f(x)=2(0.94)^x?A.a population declining rate 2%B.a population growing rate at 94%C. A population growing rate at 2%D. A population decline rate at 6%How is the expression log32-log8 written as a single logarithm?A. Log 4B. Log 8C. Log 24D. Log 40What is the value of log 25A.2B.5C.0.699D.1.398

Answer 1

1)

Option D
2(0.75)³ = 27/32 = 0.8437




2)
Option D

Substitute values
when x = 1 ; f(x) = 1.88
x = 2 ; f(x) = 1.76
x = 3 ; f(x) = 1.66
:
:

Clearly It is declining function
1.88 - 1.76 = 0.0681

= ~6%
Option D




3)
log 32 - log 8
= log (32/8)
= log 4
Option A



4)
log 25 = log 5² = 2 log 5 = 2 × 0.6989 = 1.3978

Answer 2

Answer:

1. 0.844

2. A population declining at a rate of 6%

3. log4

4. 2
