To reflect over the y axis, the formula is (-x, y). For W, which currently is (-6, -4), the -6 becomes -(-6), which is the same as 6, so the answer is (6, -4).
F(x)=2x-5
k(x)=f(x+3)=2(x+3)-5=2x+6-5=2x+1
k(x)=2x+1
From the trigonometry:
tan θ = (sin θ) / (cos θ)
cot θ = (cos θ) / (sin θ)
∴ tan θ + cot θ = (sin θ) / (cos θ) + (cos θ) / (sin θ)
= [ sin² θ + cos² θ]/( sin θ cos θ) = 1 /( sin θ cos θ )
note : sin² θ + cos² θ = 1
Answer:
yaaa
Step-by-step explanation:
The answers are:
__________________________
[B]: "√12 " ; AND:
__________________________
[D]: "<span>√20" .
__________________________
Note: "Irrational numbers" have decimals that are: 1) non-terminating; AND: 2) non-repeating.
__________________________
Consider the answer choices given; and consider the given information that there "should be no more than one answer.
__________________________________
Consider the following answer choices:
__________________________________
Choice A) "</span><span>√9" = 3 . Rule out this choice.
__________________________________
Choice C) "</span><span>√16" = 4 . Rule out this choice.
__________________________________
Choice E) "</span><span>√25" = 5. Rule out this choice.
_________________________________
We are left with 2 (two) remaining answer choices:
[B]: "</span>√12" ; and: [D]: "<span>√20" .
_________________________________
If there are more than one answer, then these two choices should be the correct answer. However, let us explore these two choices, using a calculator.
____________________________
[B]: </span>"√12" = 3.4641016151377546
[D]: "√20" = 4.4721359549995794
_________________________________
These two answer choices should the correct answers.
