Hello there!

The one is asking lot of hard work and I don't know how to write the quadratic formula so I can't show the work for this one.
The answer is : two solutions

#2
Number two is easy to show my work
0 = 3x² + 18x + 27
-3x² - 18x - 27 = 0
Now all we have to do is factorize
-3(x + 3)(x + 3) = 0
Now set each factors equal to 0
x + 3 = 0 or x + 3 = 0
x = - 3
The correct option is A - One solution

A+ Guaranteed! If you have further question or misunderstand the steps please feel free to ask.

Have a nice day!

A company estimates that it will sell ????(x) units of a product after spending x thousand dollars on advertising, as given by ?
zepelin [54]

Answer:

(11\frac{1}{3},20)

Step-by-step explanation:

If the Number of Sales of x units, N(x) is defined by the function:

N(x)=-5x^3+235x^2-3400x+20000,10\leq x\leq 40

N'(x)=-15x^2+470x-3400\\When -15x^2+470x-3400=0\\x=20, x=11\frac{1}{3}

Next, we text the critical points and the end points of the interval to see where the derivative is increasing.

N'(10)=-200\\N'(11\frac{1}{3})=0\\N'(19)=115\\N'(20)=0\\N'(40)=-8600

Thus, the rate of change of sales N'(x) is increasing in the interval (11\frac{1}{3},20) on 10≤x≤40.

To find the mean you add all the numbers and divide by how many numbers there are so in this case 2+3+4+4+6= 19, there are 5 numbers so divide 19/5

PLEASE HELP V IMPORTANT<br> the answers I input were just so I could see other questions.
marishachu [46]

Step-by-step explanation:

(T-S)(2000), when T(x) and S(x) are functions, is equivalent to T(2000)-S(2000), which is 17-7=10

We know that T(x) is equal to everything else, and everything else is S(x)+G(x), so T(x)-S(x) = G(x), or dollars spent on general science
