Answer:
D
Step-by-step explanation:
Let's draw a picture (see attachment).
We know that since our point is (-5, -12), it must pass in the third quadrant. Now, if we drop a perpendicular line from the point (-5, -12) to the x-axis, we have a right triangle. Notice that we already know the two leg lengths of this: -5 and -12.
Cosine is adjacent / hypotenuse. Here, the adjacent side to the angle θ is -5. We need to find the hypotenuse, which we can do so by using the Pythagorean Theorem:
c² = a² + b²
c² = (-5)² + (-12)²
c² = 25 + 144 = 169
c = 13
So, the hypotenuse is 13. Now, plug these values in:
cos(θ) = adjacent / hypotenuse = -5/13
The answer is D.
Answer:
100/19400*12105=62.3969072165 100-62.3969072165 = 37.60% (rounded)
Step-by-step explanation:
100% = 19'400 divide and multiply with the current value, this will give you the % deductions. Simply deduct the result from 100.
Answer:
So a ratio of 8:3 means for every 8 cars that is 3 trucks so we have the number of trucks which is 21 so what i did to find the answer was see how many times 3 went into 21 which is 7 times then you would take the 7 and times it by 8 and get 56 so there are 56 cars.

Answer:
true
Step-by-step explanation:
If the function is odd, then f(-x) = -f(x) for all x. So if the function is defined for x > 0 it must also be defined for x < 0. So that interval is NOT possible.
