What is the sum of 171

1 answer:

3 0

Divide 171 by 3. 57
Therefore the middle integer is 57
Therefore the highest integer is "2" higher = 59 
The lowest integer is 2 lower to "balance" the higher digit = 55 

Therefore using common sense rather than "let x=....." the answer is 55, 57 and 59.

The formula A=200e^.033t models the population of a particular city, in thousands, t years after 1998. When will the population

svetoff [14.1K]

Answer:

In the year 2010

Step-by-step explanation:

we have

$A=200e^{0.033t}$

where

A is the population in thousands

t is the number of years since 1998

For A=297 thousands

substitute and solve for t

$297=200e^{0.033t}$

simplify

$1.485=e^{0.033t}$

Apply ln both sides

$ln(1.485)=ln[e^{0.033t}]$

$ln(1.485)=(0.033t)ln(e)$

Remember that

$ln(e)=1$

$ln(1.485)=(0.033t)$

$t=\frac{ln(1.485)}{0.033}$

$t=12\ years$

1998+12=2010

Consider the function f(x)=(x-9)/(x^3-81x) Find the vertical asymptote(s) of f(x)

enyata [817]

Well, here's a harder one
Basically, to find a vertical asymptote, we set the denominator to 0. Like this:
x^3 - 81x = 0
Then we solve for x.
x(x^2 - 81) = 0
x(x+9)(x-9) = 0
x = 0, 9, -9
There are vertical asymptotes at x = 0, x = 9, and x = -9.
