I think the answer is acid rain ig
Answer:
Step-by-step explanation:
Recall what the relationship between cosine and secant:
In other words, secant is the reciprocal of cosine.
So, if we know cosine, we only need to find its reciprocal to find secant.
We are given that cosine is:
Then secant must be:
So:
Square:
And we're done!
B and F
the x coordinates shift one to the right, so that's B.
the image flips over the x axis so the y coordinates become negative

Answer: C) 2 km west</h3>
Explanation:
With displacement, all we care about is the beginning and end. We don't care about the middle part(s) of the journey. So we'll take the straight line route from beginning to end when it comes to computing displacement.
We start at A(0,0) and end at B(-2,0). Going from A directly to B has us go 2 km west. Keep in mind that displacement is a vector, so you must include the direction along with the distance.
Answer:
x=9
Step-by-step explanation:
The triangle is equilateral which means the sides are equal.
x+9 = 2x
Subtract x from each side
x+9-x = 2x-x
9 =x
