Answer:
x = 13 and y = 13√3
Step-by-step explanation:
Recall that sin Ф = opposite side / hypotenuse, and that
cos Ф = adjacent sice / hypotenuse.
if we recognize that the angle Ф is 30° here, then we know that:
x = opposite side = hypotenuse * sin 30° = 26*(1/2) = 13.
and....
y = adjacent side = hypotenuse*cos 30° = 26*√3/2 = 13√3
In summary, x = 13 and y = 13√3
Answer:
The answer is A.
Step-by-step explanation:
I did it.
If the ratio of the posters' perimeter is 4:5 and the larger one is 85 inches, then we may want to know how much is one "part" of the ratio - so we divide 85 by 5:
85 / 5 = 17
So the larger poster is 5 * 17 = 85, and the smaller one is 4 * 17 = 68.
Answer:
f(x) = -|x -2| +1
Step-by-step explanation:
The transformation ...
g(x) = f(x -h) +k
translates the function f(x) so that the point on its graph (0, f(0)) is moved to the location (h, k) on the graph of g(x).
The vertex of the "upside down" absolute value function f(x) = -|x| is (0, 0). In your graph, that point has been moved to (h, k) = (2, 1). So, the transformed function is ...
f(x) = -|x -2| +1 . . . . matches the last choice
