Answer:
A
Step-by-step explanation:
Let's check
The formula is 3 *6^(n-1)
The first generation had 3 rabbits
3*6(1-1) = 3*6^0 = 3*1 =3
That works
Try it again with the 2nd generation
n is the number of generation
3*6^(2-1)= 3*6^1 = 18
●●●●●●●●●●●●●●●●●●●●●
We can deduce the formula
The initial number of rabbits is 3
Each time we multiply by 6
So for the generation number n the formula will be :
3*6^(last generation-first generation)
3*6^(n-1)
It would be false to have the same sign.
Answer:
Answer:C = 8
Answer:C = 8Step-by-step explanation:
-2(4c+16)^1/4+2=-2
Move the constant to the right and change the sign
-2(4c+16)^1/4= -2-2
transform expression
![- 2 \sqrt[4]{4c - 16} = - 4](https://tex.z-dn.net/?f=%20-%202%20%20%5Csqrt%5B4%5D%7B4c%20-%2016%7D%20%20%3D%20%20-%204)
Divide each side by -2
![\sqrt[4]{4c - 16 } = 2](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7B4c%20-%2016%20%7D%20%20%3D%202)
raise both side of the equation by power of 4
4c-16=16
move constant to the right and change the sign
4c=16+16
4c=32
THEN DIVIDE BOTH SIDES BY 4
C = 8

The answer is <span>The liquid must be in the cooler fewer than 10 minutes.
</span>
Let:
m - the number of minutes the liquid is in the cooler.
a - the starting temperature
The function is:
f(m) = a - 3 * m (Since the temperature decreases by 3°F each minute m, it has a negative sign)
Let:
m - <span>the number of minutes the liquid is in the cooler.
a - the starting temperature
</span>a = 90<span>°F
</span>
<span>The temperature of a liquid must stay above 60°F:
f(m) > 60
Thus:
</span>f(m) = a - 3 * m
f(m) > 60
a - 3 * m > 60
90 - 3m > 60
90 - 60 > 3m
30 > 3 m
30/3 > m
10 > m
Or m < 10. So the correct answer is The liquid must be in the cooler fewer than 10 minutes.
