If you put 0 in the place of x or y, which every one you choose, it will cancel it or and you can just divide the number next to it by the answer (-20, 20). Take it one step at a time, don't try to do both at the same time.
Answer: 0.99
Step-by-step explanation:
SOH CAH TOA
CAH: cosine = adjacent/hypotenuse
Cosine of angle w = 84/85 = 0.98823 ≈ 0.99
Angle Y is 90 degrees, meaning it's a right triangle. Therefore angle W is the top/tip of a triangle, while X is the angle next to Y. If you plug in the information afterwards and follow the trigonometry rule (SOH CAH TOA) you will find your answer.
Answer:
-17.8884
Step-by-step explanation:
- 6.444 - 3.2222 - 8.2222 = -17.8884
The equation of the red parabola is :
therefore , correct option in A
Solution
The sequence is an Arithmetic sequence.
Here the 1st term = -13
An = A(n-1) + 4
Therefore, the common difference (d) = 4
2nd term = first term + common difference
2nd term = -13 + 4 = -9
The answer is -9.
