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)
Add up the numbers of the sides you have then subtract it from the Magic total
Answer:
330
Step-by-step explanation:
Because he runs 6 yards in 1 minute so if we multiply 55 x 6 we get 330.
Answer:
Step-by-step explanation: The answer is 400 flashlight
The answer is 3/2
you can divide each or one of the vertice(s) of the triangle A'B'C' by the triangle ABC to find the scale factor of dilation..... So
vertice of A and A'
A' (7.5)/ (5) A= 1.5 3/2=1.5
A' (4.5)/(3) A=1.5
So, if we put 3/2 in decimal is equal to 1.5, and 1.5 is the scale factor of this dilation between the division of the vertice A' by vertice A
