Answer:
LCD = 2(3)(5)(7)(x)(x) is A
LCD = (x - 3)(x + 1) is D
LCD = (x + 2)(x - 3) is C
LCD = 2(3)(5)(7)(x) is B
H(x), or the range of this function, must be y >= 0, as you can never get a negative when square rooting any number.
For the domain, x cannot exceed -2 or 2, as this would mean we'd be finding the square root of a negative number, which can't happen without getting in to imaginary numbers. Thus, the domain must be -2 <= x <= 2.
21/28 is equlvilant to 7/8
Answer: The correct option is (A). angle 1.
Step-by-step explanation: In the given diagram, the measure of ∠3 is 105°.
We are to find the angle that must also measure 120°.
We know that the measures of two vertically opposite angles are equal.
In the given diagram, since ∠1 and ∠3 are vertically opposite angles.
So, the measures of ∠1 and ∠3 are equal.
That is,
m∠1 = m∠3.
Also, m∠3 = 105°.
Therefore, m∠1 = 105°.
Thus, the measure of angle 1 must be 105°.
Option (A) is correct.
