Answer:
Step-by-step explanation:
MH is the diameter and it divides the circle in half.
MXH is the arc between the endpoints of the diameter, therefore is semicircle.
Correct choice is C
Answer:
sin 2x + cos x = 2 sin x cos x + cos x = (2 sin x + 1)cos x
Step-by-step explanation:
Given the expression: sin 2x + cos x,
then we can use the formula: sin 2x = 2 sin x cos x, which gives:
sin 2x + cos x = 2 sin x cos x + cos x = (2 sin x + 1)cos x
So there you have two expressions in terms of sin x and cos x, as requested. :D
Remember that there cannot be a negative number in an absolute value.<span />
Answer: f(-x) = x^4 -3x^2 +x^6
-f(x) = -x^4 +3x^2 - x^6
Step-by-step explanation:
at f(-x), place a negative sign inside the function of x itself:
f(-x)= (-x)^4 -3(-x)^2 +(-x)^6
because the powers are even, they cancel out.
