= 64^(t^3)*64^(-t/2)
= 64^(t^3)*(64^(-1/2))^t . . . . change the sum of exponents to a product
= 64^(t^3)*(1/√64)^t . . . . . . negative exponent signifies inverse, 1/2 power is sqrt
= 64^(t^3)/8^t . . . . . . . . . . . simplify
= (4^3)^(t^3)/8^t . . . . . . . . . .replace 64 with 4^3
= 4^(3t^3)/8^t . . . . matches the first selection only
Hello. In order to complete this question, you must have your graph, and it seems it's not there.
You could use a coordinate plane to solve this.
To reach B from point A, move 2 to the left and 9 down. Hope this helped, sorry I was in a rush-
Answer:

Step-by-step explanation:
Let d= dramas
c= comedies
r= reality shows
Dramas are 1 hour long, comedies are 30 minutes, and reality shows are 2 hours long.
Total time spent on watching = 
[
]
Since he spent 8 hours for this, that means
→ First equation
He watches twice as many comedies as dramas.
i.e.
→ second equation
So, the system of equations could be used to determine how many of each type of show he watches each week:

5 x - 30
Factor out 5
5 ( x - 6)
alternative B
hope this helps !. :)
