Answer:
D
Step-by-step explanation:
Secant is hypotenuse / adjacent, while cosine is adjacent / hypotenuse. In fact, secant = 1/cosine.
Here, we know that cos(θ) = 2/19, so sec(θ) = 1/(2/19) = 19/2.
The answer is thus D.
Answer:
x = ±6i sqrt(2)
Step-by-step explanation:
6x^2 + 432 = 0
Subtract 432 from each side
6x^2 =- 432
Divide by 6
6x^2 /6 =- 432/6
x^2 =-72
Take the square root of each side
sqrt(x^2) = ±sqrt( -72)
x = ±sqrt(-1) sqrt(2*36)
We know the square root of -1 = i
x = ±i sqrt(2*36)
x = ±i sqrt(36) sqrt(2)
x = ±6i sqrt(2)
