Answer:
quadratic
Step-by-step explanation:
Answer:
x° is divided into two parts the upper and the lower.
From the above 85° is alternate to the upper part of x°, hence the upper part of x = 85°.
Also 147° and the lower part of x° are co-interior angles, hence the lower part of x = 180° - 147° = 33°
there x° = 85° + 33° = 118°
Answer:
y=Ae^(1.25t)
Step-by-step explanation:
From the expression y=Ae^kt
After two days of the experiment, y = 49 million, t=2
After four days of the experiment, y= 600.25 million, t=4
A is the amount of bacteria present at time zero and t is the time after the experiment (in days)
At t=2 and y =49
49=Ae^2k…………….. (1)
At t=4 and y = 600.25
600.25=Ae^4k………… (2)
Divide equation (2) by equation (1)
600.25/49=(Ae^4k)/(Ae^2k )
12.25=e^2k
Take natural log of both sides
ln(12.25) =2k
2.505 =2k
k=1.25
The exponential equation that models this situation is y=Ae^(1.25t)
Answer:
bam
Step-by-step explanation:
bam
Yes it is. log(1) and ln(1) both equal zero. But you cannot take the logarithm of 0.
