he function C(x) = 400x – 0.2x2 represents the total costs for a company to produce a product, where C is the total cost in doll
liq [111]
To determine the maxima and minima of the polynomial, differentiate the given based on x and equate to 0.
                                   C(x) = 400x - 0.2x²
                               dC(x) / dt = 400 - 0.4 x = 0 
The value of x is 1000. This is the value of the maxima. As the value of C(x) continously becomes lesser as the value of x is set higher, the minima is not identified. Substitute x to the original equation,
                               C(x) = (400)(1000) - 0.2(1000²) = $ 200,000
Thus, the answer is letter B.

If DF+FE=DE, then point F is_________
Dima020 [189]
I believe the correct answer from the choices listed above is option A. If DF+FE=DE, then point F is <span>A. a midpoint of DE (with line over). F is the endpoint of line segment DF and is the starting point of line DE thus it is in between line DE. Hope this answers the question.</span>

Mia is 7.02576 × 10^6 minutes old. Convert her age to more appropriate units using years, months, and days. Assume a year has 36
Naya [18.7K]

Answer:

Number of days = 4879 days

Number of months = 162.63 months

Number of years = 13.37 years

Step-by-step explanation:

Given

Mia's age (in minutes) = 7.02576 * 10^6

Required

Calculate age in years, months and days.

For ease of work, we'll start by converting to days.

First, it should be noted that there are 24 hours in one day

And there are 60 minutes in an hour.

This means that there are 24 * 60 minutes in a day

Number of minutes = 24 * 60 minutes

Number of minutes = 1,440 minutes

So, if number of minutes in a day is 1,440

Number of days in 7.02576 * 10^6 minutes is calculated as follows

Number of days = \frac{7.02576 * 10^6}{1440}

Number of days = 4879 days

Now, we can convert this to month and year, easily.

From the question, it should be assumed that there are 30 days in a month.

If 1 month = 30 days

Then, there are \frac{4879}{30} months in 4879 days

Number of months = \frac{4879}{30}

Number of months = 162.63 months

Converting to year

From the question, it should be assumed that there are 365 days in a month.

If 1 year = 365 days

Then, there are \frac{4879}{365} years in 4879 days

Number of years= \frac{4879}{365}

Number of years = 13.37 years

Can someone help me with this please??
Llana [10]

Answer:

(x-5)*(x+5)

Step-by-step explanation:

= x^2 + 5x - 25 - 5x

= x^2 +5x - 5x -25

because +5x - 5x = 0 so

= x^2 + 0 - 25

= x^2 - 25

25 can be written as 5^2

= x^2 - 5^2

we know that a^2 - b^2 = (a-b) * (a+b)

so x^2 - 5^2

= (x-5) * (x+5)

Hope this help you :3
