Answer: f(n) + g(n) = -2n^3 + 3n^2 - 2n - 4

Explanation:

f(n) + g(n) = (-2n^3 + 3n^2) + (-2n - 4)
f(n) + g(n) = -2n^3 + 3n^2 - 2n - 4

Answer:

Choice A is correct; Kindly rate

Step-by-step explanation:

A function is said to be increasing over a given interval if the value of the function is increasing over the said interval. From the graph, the function is increasing over the interval since with every change in the x-value, the y-value is increasing

One tool used in genetics is called a pedigree chart,are there any advantages to using this tool?The population of a city is inc

Tanzania [10]

Answer:

A = 236,000 (1.04)^t

population in 2009 : 335,902 people

Step-by-step explanation:

Hi, to answer this question we have to apply an exponential growth function:

A = P (1 + r) t

Where:

p = original population

r = growing rate (decimal form) = 4/100 = 0.04

t= years passed from 2000

A = population after t years

Replacing with the values given:

A = 236,000 (1+ 0.04)^t

A = 236,000 (1.04)^t

Population in 2009.

t = 2009-2000 = 9

A = 236,000 (1.04)^9

A = 335,902 people

Feel free to ask for more if needed or if you did not understand something.

Y is directly proportional to square root of x If y=56 when x=49 find, y when x=81

STALIN [3.7K]

$\qquad \qquad \textit{direct proportional variation} \\\\ \textit{\underline{y} varies directly with \underline{x}}\qquad \qquad \stackrel{\textit{constant of variation}}{y=\stackrel{\downarrow }{k}x~\hfill } \\\\ \textit{\underline{x} varies directly with }\underline{z^5}\qquad \qquad \stackrel{\textit{constant of variation}}{x=\stackrel{\downarrow }{k}z^5~\hfill } \\\\[-0.35em] \rule{34em}{0.25pt}$

$\stackrel{\begin{array}{llll} \textit{"y" directly}\\ \textit{proportional to }\sqrt{x} \end{array}}{y = k\sqrt{x}}\qquad \textit{we know that} \begin{cases} y = 56\\ x = 49 \end{cases}\implies 56=k\sqrt{49} \\\\\\ 56=7k\implies \cfrac{56}{7}=k\implies 8=k~\hfill \boxed{y=8\sqrt{x}} \\\\\\ \textit{when x = 81, what is "y"?}\hfill y=8\sqrt{81}\implies y=8(9)\implies y=72$
