Answer:
24
Step-by-step explanation:
cos(x) is just a trigonometric function. To find it on a right triangle, you take the "adjacent" side, which should be the side next to the angle x, and divide it by the hypotenuse.
In this case, the adjacent side is 12. We don't know the hypotenuse, but we can figure it out using the Pythagorean Theorem: 
= 
= 15. So, the hypotenuse is 15.
Thus, cos(x) = 12/15 = 4/5. We want 30 * cos(x), so we get: 30 * (4/5) = 24, and that is our answer.
<span>1+4=5 2+5=12 3+6=21 8+11=40
Explanation: 1+4=5; 2+5=7+5(the previous result)=12; 3+6=9+12=21;
8+11=19+21=40.

Yeah call 911 that would be the better option
Answer:
Population of monkeys after 2 years = 3200
Step-by-step explanation:
Total number of monkeys at the start = 2975
Increase ratio of monkey population one year = 
∴ New population of monkeys after 1 year= 
Decrease ratio the next year = 
∴ Population of monkeys after 2 years= 
Answer:
In mathematics, the magnitude or size of a mathematical object is a property which determines whether the object is larger or smaller than other objects of the same kind. More formally, an object's magnitude is the displayed result of an ordering ( or ranking ) - of the class of objects to which it belongs.
