Answer:
I think he made a mistake in the first one
Step-by-step explanation:
Well first of all, let's define what an integer is...
Integers are numbers such as -2, -1, 0, 1, 2 etc etc.

If f(5)=12,
f(6)=0.3*f(6-1)
= 0.3*f(5)
= 0.3*12
= 3/10 * 12
= 36/10
= 3.6
We now know that f(6)=3.6
Now:
f(7)=0.3*f(7-1)
= 0.3*f(6)
= 0.3*3.6
= (3/10) * (36/10)
= 108/100
= 1.08
Answer:
f(7)=1.08
-288/5 or - 57.6 I used a calculator so I cannot solve step by step
Here we can use the distance formula. We label one point

and the other

. It doesn’t matter which point we label with the 1s and which we label with the 2s. The distance will be the same either way (the distance from the subway to the house is the same as that from the house to the subway — to give a related easier to follow example). What does matter is that the 1s are together and the 2s are together.
So let’s call (-4,-3)

which means that -4 is

and -3 is

. We call the other point (4,3)

The distance formula is

We substitute using the points given and obtain:

and simplify to get

The distance is 5 miles

It's 33 because If you divide it by 8 equal groups, you get 4 in each group and 1 left over. 4 is also an even number! Good luck
