Answer:

Maximum is 4

Step-by-step explanation:

M(x) is quadratic function, so we need to fin maximum.

m(x)=-x(x-4)

m(x)=-x^2+4x

To find a maximum we need to find m’

M’(x)=-2x+4

M’(x)=0 if x=2

The maximum is in the point x=2

M(2)=-2(2-4)=4

the problem is kamala had 5,026 grams flour in a canister.she brought a 4,158 gram bag of flour.she poured some flour from the

andrey2020 [161]

Hello,

x= amount of flour that she poured in the canister

there was 5,026 grams of flour, and now: 5,026+x

In the bag there was 4,158, now: 4,158

I says that as a result the mass of the flour in the canister is twice the mass of the flour left in the bag, so:

$5,026+x=2*(4,158-x) \\ 5,026+x=8,316-2x \\ 3x=8,316-5,026 \\ 3x=3,290 \\ x=1,096.67$

So, she poured 1,096.67 grams, we subtract this from the initial amount in the bag and we have the answer:

$4,158g-1,096.67=\boxed{3,061.33}$

Answer: there is 3,061.33 grams of flour in the bag
