f(n)= n^2 -6n - 16

Set f(n) =0

n^2 -6n-16=0

Factor it

(n-8)(n+2)=0

Solve for n

n-8=0 n+2=0

n=8 and n =-2

Given:

Mamont248 [21]

Option a. 11 is the right answer

Step-by-step explanation:

To find the value of a function on particular input, the value is put in the function in place of variable

Given function is:

$f(x) = \left \{ {{3x-7\ \ \ x>0} \atop {2x+3\ \ \ x$

As we have to find f(6) and x>0 the part of function 3x-7 will be used

so,

$f(6) = 3(6)-7\\= 18-7\\=11$

Hence,

Option a. 11 is the right answer

What is equivalent to <img src="https://tex.z-dn.net/?f=%283%5E6%293" id="TexFormula1" title="(3^6)3" alt="(3^6)3" align="absmid

kherson [118]

For this case we must indicate an expression equivalent to:

$(3 ^ 6) ^ 3$

For properties of powers we have to:

$(a ^ n) ^ m = a ^ {n * m}$

So, the above expression can be rewritten as:

$(3 ^ 6) ^ 3 = 3^{6*3} = 3^{18}$

Thus, the resulting expression is: $3^{ 18}$

Answer:

$3^{ 18}$
