Answer: C

<u>Step-by-step explanation:</u>

1st letter (E)     2nd letter     3rd letter    4th letter     5th letter

      ₁C₁                   ₄C₁              ₃C₁              ₂C₁               ₁C₁    

        1         x          4        x        3       x        2       x         1        = 24

or

      ₁P₁   x    ₄P₃

       1    x     24   = 24

Find an exponential function that fits the information (hint: putting them in a table may help you see).
Vilka [71]

Answer:

f(x)=8*(3.5)^x

Step-by-step explanation:

2=98

3= 98r

4= 98r^2

5= 98r^3

6= 98r^4

98r^4/98, 98 crosses out and its just r^4. r^4= 14706.125/98

r=3.5

So you plug that in and you get f(x)=8*(3.5)^x

I hope this helped. XD

Simplify each sum or difference. State any restrictions on the variables.
maria [59]

Simplification of the equation \frac{x}{3x+9}- \frac{8}{x^{2}  +3x} is equal to (x² -24)/ 3x(x+3), restriction on the variables are x ≠0 , x≠ -3.

As given in the question,

Given equation \frac{x}{3x+9}- \frac{8}{x^{2}  +3x}

Simplify the given equation,

x/ 3(x+3) - 8/x(x+3)

= (x² - 24) / 3x(x+3)

Restriction on the variables for the above equation is,

x≠ 0 , x≠ -3

Therefore, simplification of the equation \frac{x}{3x+9}- \frac{8}{x^{2}  +3x} is equal to (x² -24)/ 3x(x+3), restriction on the variables are x ≠0 , x≠ -3.
