Find maximum points y=11^(6x-x²) solve using derivative
Darya [45]

Answer:

\boxed{\sf \ \ \ maximum \ is \ 11^9=2357947691 \ \ \ }

Step-by-step explanation:

hello

y = 11^{(6x-x^2)}=exp((6x-x^2)ln(11))

so to know the maximum to y we can check the maximum of

f(x)=6x-x^2

f is derivable and f'(x)=6-2x

f'(x)=0 <=> x = 3

so the maximum is reached for x = 3

f(3)=18-9=9

and then

y = 11^9=2357947691

to be rigorous, we can write the variation table of y to show that there is only one maximum

hope this helps

Why do we square the residuals when using the least-squares line method to find the line of best fit?
Mekhanik [1.2K]

We square the residuals when using the least-squares line method to find the line of best fit because we believe that huge negative residuals (i.e., points well below the line) are just as harmful as large positive residuals (i.e., points that are high above the line).

<h3>What do you mean by Residuals?</h3>

We treat both positive and negative disparities equally by squaring the residual values.  We cannot discover a single straight line that concurrently minimizes all residuals. The average (squared) residual value is instead minimized.

We might also take the absolute values of the residuals rather than squaring them. Positive disparities are viewed as just as harmful as negative ones under both strategies.

I would like to know the answer for this question
g100num [7]
To put words into equations:
x+y+z =50
x=4y
4y=5z -> z= 4/5 y


Which means
4y+y+ 4/5 y= 50
29/5 y =50
29y=250
Y=29/250

In the 2009 to 2010 school year in country a there were 127,004 in students from country B. This number is 24% more than the num
adoni [48]
If x represents the number of students from country C.

then 122% of x = 116,000

122/100 * x = 116000

Transposing the formula for x;

therefore x = 116000 * 100/122 = 95,082 students
