Answer:
3 days
Step-by-step explanation:
20/6 is 3.333
Answer:
2^x
64 bacterium
10 hours
Step-by-step explanation:
doubles every hour
if x = hours
2^x
2^x --> 2⁶ = 64
2^x = 1024
1024 = 2^10 ---> x=10
Answer:
solution is
![x=1.353,y=1.613](https://tex.z-dn.net/?f=x%3D1.353%2Cy%3D1.613)
Step-by-step explanation:
We are given equation as
![log_2(3x-1)=log_4(x+8)](https://tex.z-dn.net/?f=log_2%283x-1%29%3Dlog_4%28x%2B8%29)
Firstly, we will find equations
First equation is
![y=log_2(3x-1)](https://tex.z-dn.net/?f=y%3Dlog_2%283x-1%29)
Second equation is
![y=log_4(x+8)](https://tex.z-dn.net/?f=y%3Dlog_4%28x%2B8%29)
now, we can draw graph
and then we can find intersection point
we can see that
intersection point is (1.353,1.613)
so, solution is
![x=1.353,y=1.613](https://tex.z-dn.net/?f=x%3D1.353%2Cy%3D1.613)
The <span>expression that represents n plus 7 multiplied by 3 is
(n + 7)(3)
The entire expression, (n + 7) is multiplied by 3 since it would be inconvenient to state the expression as given above if what is meant was
(n + 7x3). It would have simply been n plus 21.</span>
