Step-by-step explanation: In order to find the maximum value of a function, you can take the derivative of the function and equalize the result to 0.

f'(x)=(-3x^2 + 12x)'=-6x+12=0

x=2

When x is 2, the function will reach its maximum value.

f(2)=-3(2)^2 + 12.2 = -12 + 24 = 12

The maximum value (f(x)) is equal to 12 and the time passed is 2 minutes which is equal to 120 seconds.

Help if you can but this is kinda urgent any help is welcome tho

Answer:

(Change in y)/(change in x) is defined as the average rate of change.

For a linear equation:

y = a*x + b

A is the average rate of change, and is called the "slope" of the linear equation, and this is a constant.

Then the sentence will be:

"The average change between two ordered pairs (x,y) is the ratio (change in x)/(change in y)

In a linear function, this is called the slope, and it is constant"

A recipe for crumb cake says to mix 3/8 cup of brown sugar and 1/3 cup of white sugar. From this sugar mixture, set aside 1/4 cu

ch4aika [34]

brown sugar= $\frac{3}{8}$

white sugar= $\frac{1}{3}$

you need to mix brown sugar with white sugar

$\frac{3}{8}$ + $\frac{1}{3}$ = $\frac{9+8}{24}$ = $\frac{17}{24}$

then it says you need to set aside 1/4 for the crumb topping from the previous sugar mixture that was $\frac{17}{24}$ , so

$\frac{17}{24}$ - $\frac{1}{4}$ = $\frac{68-24}{96}$ = $\frac{11}{24}$

The sugar mixture used to make the cake is $\frac{11}{24}$
