Answer:
a) Log ( 2 ) = 4t Log ( 83/80 )
b) 4.7 years
Step-by-step explanation:
Attached below is the detailed solution
<u>a) exponential statement in log form for an investment at 15% quarterly </u>
Log ( 2 ) = 4t Log ( 83/80 )
n = 4 , r = 15
<u>b) using change to base to find double time in yr </u>
Double time in yr
t = Log ( 2 ) / 4log ( 83/80 )
= 4.7 years
Answer:
6400
Step-by-step explanation:
Given the profit function ;
P(c) = –20c2 + 320c + 5,120
The maximum value is given by :
f(h) ; where, h = - b /2a
From P(C) ; a = - 20 ; b = 320
h = - b / 2a = - 320 / 2(-20) = - 320 / 40 = 8
c = h
P(8) = –20(8)² + 320(8) + 5,120
P(8) = - 1280 + 2560 + 5120
= 6400
Answer:
100 • 1.06
Step-by-step explanation:
To get from 100 to 106, simply multiply; 100 • 1.06
The answer is 51
6+36- (-9)
42- (-9)
Answer:
g(x + 8) = 10x + 105 wherever you see it among your answers.
Step-by-step explanation:
I think I have enough here that I can answer the question, but you should always put in your givens.
f(x) = 10x + 25 Put g(x) where you see x in f(x)
f(g(x)) = 10(g(x) + 25 Put the value for g(x) where you see g(x)
f(x+8) = 10(x + 8) + 25 This might be the answer
From here it is a guess.
f(x+8) = 10x + 80 + 25 Combine the like terms
f(x+8) = 10x + 105
