Answer:
6.065; 7.358 ; 6.694
Step-by-step explanation:
Given that, profit is quoted using the function :
R = 2pe ^ -0.1p
(a)
When price 'p' = $5
R = 2(5)e^(-0.1*5)
R = 10e^(-0.5)
R = 10 * 0.6065306
R = 6.065
B)
When price 'p' = $10
R = 2(10)e^(-0.1*10)
R = 20e^(-1)
R = 20 * 0.3678794
R = 7.358
C.)
When price 'p' = $15
R = 2(15)e^(-0.1*15)
R = 30e^(-1.5)
R = 30 * 0.2231301
R = 6.694
X=8 is the Answer. So the equation would be <span>-8+4(1+5 times 8 )=156 </span>
Base×Height = Area
So put (2x-6)(x+3) which equals
2x^2+6x-6x-18
Combine like terms=
2x^3-18
Simplify by diving each term by 2 since both terms have factors of 2.
Final Answer = x^2-9
Answer:
decay rate is 2.44% per year
after 40 years, 400*(e^-0.976)=150.73 gm
300=400(e^-0.0244t)
0.75=e^-0.0244t
ln both sides
-0.2877=-0.0244t
t=11.79 years
t (1/2) occurs when ln(0.5)=-0.0244t
t=28.41 years
Have a nice day!
