Answer:
X=20Tan(25)
Step-by-step explanation:
So because the cat is looking at the tree it is a strait line making a right triangle with the tree. The cat spots the bird 25 degrees up in the tree making a triangle. Then use SohCahToa, and because u have the adjacent side use Tangent because you are missing the opposite side of the angle. There are a few other ways to find it but that is the simplest way to perform this, GOOD LUCK!
Answer:
<h2>B. y=25x+50</h2>
Step-by-step explanation:
We need to use two points on the line: (0,50) and (2,100).
Then, we find the slope with the formula

Then, we use the point-slope formula to find the equation

Therefore, the right answer is B.
Answer:
t0 = π/4
Step-by-step explanation:
The velocity v(t) = r'(t) = <-2sint,-2cost>
Since <1,-1>⊥v, <1,-1>•v=0. So,
(1)(-2sint) + (-1)(-2cost) = 0
cost - sint = 0

4=a
Answer:
1) x = -2
Step-by-step explanation:
1) x + 7 + x + 11 = 14
2x + 18 = 14
2x = 14 - 18
2x = -4
x = -4/2 = -2
