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

The table of values represents an exponential function f(x).

Ostrovityanka [42]

Answer:

-3.98 (nearest hundredth)

Step-by-step explanation:

The average rate of change of function f(x) over the interval a ≤ x ≤ b is given by:

$\dfrac{f(b)-f(a)}{b-a}$

Given interval: -2 ≤ x ≤ 2

$\implies a = -2$

$\implies b = 2$

$\implies f(a) = f(-2)=16$

$\implies f(b) =f(2)= \dfrac{1}{16}$

Substituting the values into the equation:

$\begin{aligned}\implies \textsf{rate of change} & =\dfrac{\frac{1}{16}-16}{2-(-2)}\\\\ & = \dfrac{-\frac{255}{16}}{4}\\\\ & = -\dfrac{255}{64}\\\\ & = -3.98\: \sf (nearest\:hundredth)\end{aligned}$

CAN SOMEONE PLSSS HELP WITH 27 , 28,29!

djverab [1.8K]

The area for 27 is 64cm^2.

For the mean, you add up all the numbers then divide by how many numbers there are. So you would do 45+96+100+39+50 and divide it by 5. So your mean is 66.

Now for 29.
For when n=5 is 8
For when n=8 is 14
For when n=14 is 26

Hope this helps!
