Answer:

13.6 (Answer C)

Step-by-step explanation:

I think you meant  f(n) = 0.4 * f(n-1) + 12, where * represents multiplication.

Then f(2) = 0.4 * (4) + 12, or 1.6 + 12, or 13.6.

Answer:

Assuming you have f(n)=0.4f(n-1)+12 with f(1)=4, the answer is f(2)=13.6.

Step-by-step explanation:

I think that says f(n)=0.4f(n-1)+12 with f(1)=4.

Now we want to find f(2) so replace n with 2:

This gives you:

f(2)=0.4f(2-1)+12

f(2)=0.4f(1)+12

f(2)=0.4(4)+12

f(2)=1.6+12

f(2)=13.6

12p + 7 &gt; 139 greater or less than
bazaltina [42]

Answer:

\Huge \boxed{p>11}

Step-by-step explanation:

First, subtract by 7 both sides of equation.

\displaystyle 12p+7-7>139-7

Solve.

\displaystyle 139-7=132

12p>132

Then, divide by 12 both sides of equation.

\displaystyle \frac{12p}{12}=\frac{132}{12}

Solve to find the answer.

\displaystyle 132\div12=11

\huge \boxed{p>11}, which is our answer.
