Answer:
A. AB
Step-by-step explanation:
line segment AB is a chord.
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)
2n-10<28
+10 +10 adding 10 to both sides to get the variable alone
2n<38
_____ divide both sides by 2 to get n by itself on one side
2
n<19
Check:
(2(18))-10<28
36-10<28
26<28 .......................IT WORKS!!!
Answer:
304
Step-by-step explanation:
I divided 38 by 1/8 and then checked if 304 times 1/8 equals 38
Answer:
a^3+3a^2b+3a^2c+3ab^2+3ac^2+6abc+b^3+c^3+3bc^2+3b^2c if you want it expand
(a+b+c)(a+b+c)(a+b+c) is equal to (a+b+c)^3
