Answer: it’s obviously 7 are u bad -_-
Step-by-step explanation:
To answer this question, we must know some identities:
1. cos(x) is an even function, so cos(x)=cos(-x) [this makes choice (c) true]
2. sin(x) and cos(x) are the same periodic functions with a phase-shift of pi/2, so that sin(x+pi/2)=cos(x) [this makes choice (b) true]
3. also, sin(x) is symmetrical about pi/2, and cos(x) is symmetrical about x=0. This means that sin(x)=cos(pi/2-x) [ this case is not present in the choices ]
(1,6), (6,1), (2,5), (5,2), (3,4), (4,3) are all of the possible sums of 7. So that's 6/36 possible answers. Reduced we get 1/6.
Answer: 5 meters.
Step-by-step explanation:
When a circle circumscribed about a rectangle,
Then the diameter of the circle = Diagonal of the rectangle,
Here, the length of the rectangle = 8 cm,
And, the width of the rectangle = 6 cm,
Thus, the diameter of the circle = 10 meters
⇒ Radius of the circle = diameter/2 = 10/2 = 5 meters.
