Write the function below in the form .P=Po^a^t Is this exponential growth or exponential decay? P=2e^-2.2t
1 answer:
Answer:
- P = 2·0.1108^t
- decay
Step-by-step explanation:
The multiplying factor (2) remains the same in any form in which the variable stands alone. The base of the exponential term can be determined by separating the parts of the exponent:
e^(-2.2t) = (e^-2.2)^t = 0.1108^t
Then the function is ...
P = 2·0.1108^t
_____
This could also be written as ...
P = 0.1108^(t-0.3151) . . . . . where the variable does not stand alone in the exponent

Answer:
Eva's age is 44 years
Step-by-step explanation:
Let
x ----> Brita's age
y ----> Eva's age
we know that
The sum or their ages 118
so
----> equation A
The difference in age between Brita and her daughter Eva is 30 years
so
----> equation B
Solve the system by elimination
Adds equation A and equation B
<em>Find the value of y</em>
substitute the value of x in any equation
therefore
Eva's age is 44 years
