Answer:

B) because 18 times 100 is equal to 5 times x, which means that x is equal to

Step-by-step explanation:

B is the only statement that is true

If you use cross product property to solve these proportions B is the only one that is correct

A) 18/x and 5/100 x= 360 not 36

B) 18/x and 5/100 x=360

C) 18/100 and 5/x x = 27.7 not 36

D) 18/100 and 5/x x= 27.7 not 360

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
