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.
Actually Welcome to the Concept of the Graphs and plots,
since the given equation is a parabolic equation graph, hence we substitute every value to get the value of variable y.
1.) if x = -5 ,then 25-30-7 => y = -12
2.) if x = -1 , then 1-6-7 => y = -12
3.) if x = -6 , then 36 -36 -7=> y = -7
4.) if x = 0 , then 0+0-7 => y = -7
hence all values are proved above
