Answer:
The first graph in the top left hand corner
Step-by-step explanation:
Factors of 27 are 1, 3, 9, 27.
She can make 5 rectangular prisms os sizes 1 x 1 x 27 or 1 x 3 x 9 or 1 x 9 x 3 or 3 x 3 x 3 or 3 x 9 x 1
Inputs are the first number output is the second. So youre outputs are 2, -1, -1, and 3. so i would say b
Answer:

Step-by-step explanation:
Sin2α = 2SinαCosα.
Cos2α = (Cosα)^2 - (Sinα)^2.
Sin4α can be written as Sin2(2α).
Similarly Cos4α can be written as Cos2(2α).

It is given that tanα=3.
Sinα(Sinα) =
[
], the values either be both positive or both negative, as the value of tanα is positive only on first and third quadrant.
Sin4α =
.
Cos4α =
