Please help me with this!! ***BRAINLIEST IF 2 PPL ANSWER**

Mathematics
1 answer:
marissa [1.9K]3 years ago
5 0

Answer:


Step-by-step explanation:

Problem One

19 + 2*ln(x) = 25                  Subtract 19 from both sides

19 - 19 + 2ln(x) = 25 - 19      Combine

2* ln(x) = 6                           Divide by 2

ln(x) = 3                                Take the inverse log

e^(ln(x)) = e^3                       Reduce

x = 20.09

Problem 2

Getting this to graph in Desmos can be a bit of trouble.  The correct format is y = abs(x^2 - 3x + 1). Knowing about abs and getting the quadratic to work are two separate [and difficult] problems.

The graph for this is below.

The answers (according to Desmos) are (2,1) and (3.4, 2.4). I think you should include D but that is a matter of opinion. I think it's a typo. Whoever made the question up may actually get that answer.

What value should be added to the expression to create a perfect square? x^2 - 20x
boyakko [2]
To complete the square:
we take the coefficient ox "x" (which in this problem is -20)
we divide it by 2
square that number
then add it to both sides of the equation

-20 / 2 = -10
-10^2 = 100
then we add 100 to both sides of the equation:
x^2 -20x
x^2 -20x +100 = 100
******************************************************
To get the roots of the equation, we take the square root of both sides:
(x -10) * (x-10) = 10
(x-10) = square root (10)
x-10 = <span> <span> <span> 3.1622776602 </span> </span> </span>
x1 = <span> <span> <span> 13.1622776602 </span>
and don't forget that square root of 10 also equals  </span></span><span><span><span> -3.1622776602 </span> </span> </span>

The temperature in Jonestown and cooperville was the same at 1:00. By 2:00, the temperature in Jonestown dropped 10 degrees, and
lisabon 2012 [21]
If the temperature at 1:00 is x, then Jonestown's temperature at 3:00 is 
x-10-8 (since it dropped 10 degrees then 8 more degrees)=x-18

Using x for Cooperville too, we get x-6-2 (since it drops 6 degrees then 2 more degrees) = x-8 

Since -8 is greater than -18, Cooperville's temperature is warmer and Jonestown's temperature is lower aka colder<span />
