6 0

Answer:

20

Step-by-step explanation:

\displaystyle \frac{39(100)+x}{40}=98\\\\3900+x=3920\\\\x=20

Therefore, the remaining student scored a 20 (which sounds weird, but I'm going with it).

Basically you’re multiplying them both
(x^3 + 2x - 1)(x^4 - x^3 + 3)

so you need to make sure you multiply each one, if you do it right, you should end up with
x^7 - x^6 + 3x^3 + 2x^5 - 2x^4 + 6x -x^4 +x^3 -3

simplify by adding like terms
x^7 - x^6 + 2x^5 - 3x^4 + 4x^3 + 6x - 3

your answer would be the third option

Write sin(19°) in terms of cosine.
Leto [7]

Answer:

cos(71)

Step-by-step explanation:

Since 19° is less than 90, we can express this in terms of confunction.

sin(θ) = cos(90-θ)

sin(19) = cos(90-19)

sin(19) = cos(71)
