The function f(x) = –2(x – 10)(x – 200) represents a company's monthly profit as a function of the number of items sold, x. What is the maximum monthly profit?

Answers

Answer 1

Answer: expand
f(x)=-2x^2+420x-4000
in form
f(x)=ax^2+bx+c
vertex (highest or lowest point, depending on graph)
vertex is -b/2a that is the x value
to find the profit, plug that x value back in

f(x)=-2x^2+420x-4000
-b/2a=-420/(2)(-2)=-420/-4=105

x min valu is 105
input to find profit
f(105)=-2(105-10)(105-200)
f(105)=-2(95)(-95)
f(105)=18050

max profit is $18050

How do you do this problem ?5y 9≤4?

Answers

The solution to inequality is,

⇒ y ≤ - 1

We have to give that,

An inequality to solve,

5y + 9 ≤ 4

Now, Simplify the inequality as,

⇒ 5y + 9 ≤ 4

Subtract 9 on both sides,

⇒ 5y + 9 - 9 ≤ 4 - 9

⇒ 5y ≤ - 5

⇒ y ≤ - 5/5

⇒ y ≤ - 1

Therefore, The solution is,

⇒ y ≤ - 1

5y+9≤4
minus 9 both sides
5y+9-9≤4-9
5y+0≤-5
5y≤-5
divdie both sides by 5

A gardener weeds 2/3 of a flower bed in 6 min. How much of the flower bed did the gardener weed in 1 min?

(50 pts) (This is my own experiment 2 see how fast Brainly is and how efficient!)

Answers

(2/3 bed) / (6min) = ('x' bed) / (1min)

Cross-multiply:

(2/3 bed * 3min) = ('x' bed * 6min)

Divide each side by 6min:

1/3 bed = 'x' bed

What is the number between 1026 and 1254

Answers

The number between 1026 and 1254 is 1140 by using the formula average.

To find the number between 1026 and 1254, you can take the average of these two numbers.

The average of two numbers is found by adding them together and then dividing the sum by 2.

Average = (1026 + 1254) / 2

Average = 2280 / 2

Average = 1140

So, the number between 1026 and 1254 is 1140.

It takes omar four minutes to eat eight carrots sticks. how long does it take him to eat one ?

Answers

It takes Omar 30 seconds to eat one considering he ate 8 in 4 minutes ...

If we really wanted to we could turn this into the fraction 8/4
8 being the amount of carrot sticks he ate and 4 being the time it took
now all u have to do is simplify that turns into 2/1 and since the 1 is one minute and her can eat 2 in one minute we can safely say he eats 1 carrot stick every 30 seconds

:) hope this helps!!
