Answer:
Intial Value: f(t) = 2 , Exponential Growth
Step-by-step explanation:
To find the initial value, all we have to do is find the value of f(t) at t = 0
In this case the given equation becomes
from the law of indices we know that any number with the power 0 is equal to 1 (except 0 with the power 0)
hence the above equation becomes
so the initial value is 2.
To find out whether this is exponential growth or exponential decay we need to see whether the base value of the power t is less than 1 or greater than 1, i.e. from
is
> 1 or < 1
if the value is greater, then with each increment in power, the total value will increase while if it is less than 1 then with each increment in power the total value will decrease.
Hence since > 1 then this is an exponential growth

Step-by-step explanation:
To find the amount of profit earned in each product,apply the percent profit formula;
%profit= profit/original price *100
<u>a)Candy </u>
% Profit =65%
Selling price = $6400
This means;
165%=6400
100%=?
Cross multiply
(100*6400)/165 =$3878.80
Original price= $3878.80
Profit= $6400-$3878.80
=$2521.20
<u>b)Wrapping Paper</u>
%profit= 40%
Selling price= $1200
This means;
140%=$1200
100%=?
Cross-multiply
(1200*100)/140=$857.14
Original price=$857.14
Profit=$1200-$857.14
=$342.90
<u>c)Stationery</u>
%profit= 50%
Selling price =$900
This means;
150%=900
100%=?
Cross-multiply
(900*100)/150 = $600
Original price = $600
Profit= $900-$600=$300
<u>d)Calender's</u>
%Profit=25%
Selling price=$3120
This means;
125%=$3120
100%=?
Cross-multiply
(100*3120)/125=$2496
Original Price=$2496
Profit= $3120-$2496=$624
2)
Selling price for pens and pencils =$4500
%percent profit earned = 42%
Profit earned will be:
142% = $4500
100%=?
Cross-multiply
(100*4500)/142 =3169.01
Original price=$3169.01
Profit= $4500-$3169.01
=$ 1331
