Answer:
146.6
Step-by-step explanation:
0.47 * 312=146.64 when rounded to the nearest tenth that = 146.6
Answer:
B. Number the students on the school roster. Use a table of random numbers to choose 160 students from this roster for the survey.
Step-by-step explanation:
The exponential equation that gives the number of bees in week 12 is of:
![y = 4(3)^{11} = 708588](https://tex.z-dn.net/?f=y%20%3D%204%283%29%5E%7B11%7D%20%3D%20708588)
<h3>What is an exponential function?</h3>
It is modeled by:
![y = ab^x](https://tex.z-dn.net/?f=y%20%3D%20ab%5Ex)
In which:
In this problem, considering that the initial week is the first, and the value triples every week, the expression for the number of bees after x weeks is given by:
![y = 4(3)^{x - 1}](https://tex.z-dn.net/?f=y%20%3D%204%283%29%5E%7Bx%20-%201%7D)
Hence, after 12 weeks, the expression is:
![y = 4(3)^{11} = 708588](https://tex.z-dn.net/?f=y%20%3D%204%283%29%5E%7B11%7D%20%3D%20708588)

Answer:
(g o f)(x) =
(not simplified)
Step-by-step explanation:
(g o f)(x) = g(f(x))
g(x) =
f(x) = ![x^{3} + 9x](https://tex.z-dn.net/?f=x%5E%7B3%7D%20%2B%209x)
g(f(-5)) = g(
=
= ![-170](https://tex.z-dn.net/?f=-170)
g(-170) =
= ![\sqrt{-510}](https://tex.z-dn.net/?f=%5Csqrt%7B-510%7D)
