Answer:

Step-by-step explanation:
The given function is

To find F(2), we substitute t=2 into the function.
This means that wherever we see t, we put 2

We multiply the exponent in the denominator to get:

We evaluate to get:

We now cancel the common factors to get:

There could be 6 groups of 7 kids, 7 groups of 6 kids, or 14 groups of 4 kids.
56÷7=6 or 56÷4=14.
Answer:
A
Step-by-step explanation:
The TV to have a 16:9 ratio and have a diagonal of 65 inches must have a length & width whose squares add to 4,225 (65 squared) and whose ratio length and width simplifies to 16/9.
B is not an option because
.
C is not an option because
which is 1.777777777778 as a decimal.
D fails for the same reason as C.
Therefore A is the solution because
and 
We are told that f(1) = -1.5, and that f(n+1) = -2f(n).
Then: f(2) = -2f(1) = -2(-1.5) = +3 (answer)
